How far could you go with Architectural Software?

You learn AutoCAD, then Photoshop, then SketchUp, then Revit, then 3DMax...See how far others have gone...
Català - Castellano
If you followed similar steps as I did, probably you started in School learning som CAD software. I was actually taught Microstation SE back in 1998. Together with this you probably learned some image editing program like Photoshop or Corel Draw to improve your presentations (I actually love the discussions between people with vector shaped brains because they learned Corel first and those with Raster shaped ones because they stated with Photoshop).
Soon after that comes the attempt to go 3D, not only for presentation purposes, but also from the design point of view.
Before @last software released SketchUp (yes, Google didn't create SketchUp, they bought it in 2006) crossing the 3D threshold was too much for many. Many of my friends back in School would say "I can't do 3D", nowadays it seems to me impossible to imagine an architecture school without almost all the students using SketchUp or something similar to design their buildings.
The use of 3D modeling programs is vital as I see it in the design process. Some old school guys say that real models are better, but I respectfully disagree. While a real model is a great tool to show to clients and to get a sense of scale of what you are doing, it rarely allows you to understand the real effect of the buildings and spaces you are creating. Modeling in the computer allows you to get that view from the human position as if you were in the project.
The hard step to do next is to have the ability to use 3D not only for design purposes but for presentation. Reaching and acceptable level of Image realism (enough to look professional with a client or to not let your professor make fun of you) takes some time. The most challenging part is to be able to stick to one rendering program/plugin and develop your skills fully.
In many years I've got into 3D MAX, V-Ray, Maxwell, Cinema 4D, Rhino... I have to say that for the easy of use so far Maxwell Render has proven to be the easiest to use (although render times sometimes skyrocket when using Multilight).
Many have followed this road before, and some have been extremely successful in getting the most of the process, reaching levels of excellence with Computer Graphics Software that allowed them to jump to other fields thanks to that.
I was reading in CGArchitect an Interview with Tino Schädler, who starting with an Architect background made it to the Film industry after becoming truly proficient with Maya.
Thanks to Tino, i got to discover some CG Artists who have done great jobs lately. Like Joseph Kosinski. For most of us involved in Architecture Software and struggling to work smarter, it seems a very long shot to ever reach similar levels, but as the end of this post I thought it would be nice to dream a bit.
Those levels of imagery require of course full time dedication, super powerful computers and time, but as read in Tino's Interview, improving those skills (even if it doesn't mean that you will turn into a CG Artist) can only help you on your daily struggle for better designs, better buildings (and better pay).

AutoCAD: Things that SHIFT can do for you

Do you know that the SHIFT Key can make your life much simpler?
Català - Castellano - Deutsch
After many months finding tips about how to work smarter and easier, I realized that some Keys in the keyboard really make a difference on your work speed. That is the reason why I want to start a series of posts explaining what some of these keys can do for you, to improve the way you work.
We will start with the SHIFT Key, since it is the one that so far has proven to me more useful. This is a quick list of how SHIFT will make you work faster with AutoCAD:

• SHIFT while drawing a line will lock the perpendicular inference. It is like a temporary activation of the ORTHO mode. If you press SHIFT, a tooltip with similar to the macro Icon of digital cameras appear to show you that ORTHO mode is temporary active.
• When using FILLET or CHAMFER, pressing SHIFT while selecting the second entity will override the fillet radius or the chamfer distances with a value of 0. Very useful if you want to keep certain radius or chamfer distance but once in a while you need a sharp corner.
• When Selecting Grips of an object, holding SHIFT will allow us to select multiple grips (deeply explained here).
• When we are selecting objects, pressing SHIFT will allow us to deselect any of them.
• When using TRIM or EXTEND, pressing SHIFT will toggle between one command and the other (i.e. if you typed TRIM and press SHIFT and select the object, it will extend instead of trim).
• For object snap tracking, object points are automatically acquired. If you press SHIFT you will avoid acquiring points for object snap tracking.
  
• SHIFT + SPACEBAR: cycle through selection peviews If selection preview is turned on, you can cycle through the objects by rolling over the object on top to highlight it, and pressing and holding SHIFT and then pressing SPACEBAR continuously. When the required object is highlighted, left-click to select it. If selection preview is turned off, hold down SHIFT + SPACEBAR and click to cycle through these objects, one after the other, until the one you want is selected. Press ESC to turn off cycling.
• SHIFT + RIGHT MOUSE CLICK: Will call the Osnap contextual menu (see more here).
• SHIFT + TAB: When working with Dynamic dimensions, it cycles backward through all editable dimensions (TAB only will cycle forward)
• On AutoCAD Architecture, when we draw Walls, SHIFT allows us to choose the Justification Line. Once we started drawind the wall, by prssing SHIFT we will cycle throught the different possibilities (left, center or right)
  

I have to confess that 2 or 3 of these tips I never use them, but some others have become so fundamental to my workflow, that is hard to imagine how I worked without them for so long.

Architecture Software Acronyms

What do all these acronyms stand for? CAD, CAM, BIM, IPD, CAE, AEC...Not so long ago, a friend of mine started publishing in his blog a list of Acronyms related to the Business Intelligence field. For a long time I wanted to do something similar, so finally that pushed my laziness away and here comes the list.
Since this website deals with Architecture related software, I'll try to list all those acronyms related to this topic, or at list the ones that I am acquainted with. The list might get updated as new abbreviations develop or I get to know them. Here is the list:

• CAD: Computer Aided Design. Sometimes also referred as CADD (for Computer aided Design and Drafting). The most basic one (and the one that gives name to this website). Although originally understood for 2D drafting with a computer, nowadays is also used to refer to 3d Design. Most of the big names in CAD software deliver products with strong 3D modelling capabilities. The Almighty AutoCAD is the industry most widely spread CAD package in the construction industry.
  
• CAM: Computer Aided Manufacturing. Originally Computer Aided Machining. Is the use of computers (and designs generally prooduced with CAD systems), to streamline the production of goods.
  
• CAE: Computer Aided Engineering. Although in many countries the functions of CAE software are performed by Engineers and not by Architects, in some places like Spain, the Architect still plays the main role in this field, specially on Building Structural Analysis. The tasks accomplished with this software are analysis, simulation, design, diagnosis of built solutions (and thus, of buildings) and many others. The software range might go from CAD/CAM software to Structural analysis programs, Heating and AC system calculators, etc.
• AEC: Architecture Engineering and Construction. The explanation is kind of obvious, software or any tool related to these 3 fields. The abbreviation is used by many BIM software to name some of the tools such as the AEC Polygons.
• BIM: Building Information Modelling. This is were the industry seems to be strongly moving to. BIM means not only building a 3D modell of a building, but also adding to these model all sorts of real life properties, such as materials, plumbing, structure, etc. It is in certain way like building in a computer a complete model previous to the construction of the real thing. ArchiCAD is known to be the first BIM software (released in 1987), other big names on BIM are Revit by Autodesk, Allplan by Nemetschek or Bentley Architecture (the BIM version of Microstation).
  
• IPD: Integrated Project Delivery. Not very extensively explained, seems to be a step forward from BIM. A way to not only build a model that has all the information of a project, but also to create an interconnection between Architects, Owners and Constructors (and all providers involved in the process) to minimize costs and maximize building efficiency. In this video, you can see a brief (and a bit stressing) introduction to IPD.
• CGI: Computer Generated Imagery. A wide meaning of this would be any image you produced using the computer (kinda obvious eh!). The use of the term refers mostly to 3D imagery and animations produced using any of the softwares explained above (and many others)
  

There are other 3 letter Acronyms related to architecture like GMP (Guaranteed Maximum Price) and others, but I am not going to explain them here since they have few to do with Architecture related Software

AutoCAD: PROJMODE system variable

Control the projection mode for TRIM and EXTEND commands. Recently a colleague asked me: "When I am unable to trim lines, because “EDGE IS PERPENDICULAR TO UCS XY PLANE”.. what do I do?". I sincerely had no idea, but since "I don't know" is not the kind of answer I like to give I started looking for an answer. Googleling the problem showed that the quick solution was to set PROJMODE to 0. Tried and it worked. The next step was to know what was PROJMODE.
PROJMODE is a system variable that allows us to control the projection settings for the TRIM and EXTEND Commands. The default option for PROJMODE is 1. These are the three states of the variable and their result:

• PROJMODE (0): True 3D mode. This means that if two objects are not coplanar, you will not be able to TRIM or EXTEND using them as a reference.
• PROJMODE (1): Default setting. It projects to the XY plane of the current UCS. See that this will allow you to trim or extend lines that have different Z values, but the lines will remain on different planes. Remember that the command FLATTEN is an Express Tool that allows you to bring all geometry to Z=0
• PROJMODE (2): It projects to the XY plane of the current view. If your view is alligned with the current UCS (using the PLAN command or alligning the view by default to the UCS) there is no difference between setting the variable to 1 or to 2. If the view has been rotated the results on trimming will vary.

I still have not very clearly found out the reasons for initial error message, but at least we found a work around and we learned something new.

SketchUp: Turning the Rotate Plane 90 degrees

How can you turn the rotate plane to be 90 degrees of a face? I've been struggling for so long and it was so easy...
Català - Castellano
For a long time I struggled to figure out how to rotate a surface on any plane that wasn't that of the surface itself.
Let me say it differently, imagine that you draw a circle, and then you want to turn that circle 90 degrees.The rotate tool will magnet to the circle plane(the plane perpendicular to the blue axis if you drew the circle on the ground). Rotating the circle using the green or red planes becomes troublesome without this.
And THIS is basically to know that if you click and drag on the surface of that circle, you'll be able to select any perpendicular plane to the surface.
This tip is, funny enough, kind of explained in the introductory tips of sketchup, under the chapter "creating a sphere". I think it is a good lesson for me to never underestimate what you can find in the default help of a program...

SketchUp: Bonus Packs, Extra Materials and Components

Did you know that Google itself provides more Components and Materials than those installed in SketchUp?
Deutsch - Català - Castellano
The installation of SketchUp will provide you with a reasonable amount of components and materials. But if you feel like you need more, be aware that Google itself provides free bonus packs to download from this website.
Specially useful is (was) the set of new materials. (update: the set of extra materials is no longer available online) Be aware that installing this bonus packs will overwrite the previous components if they are of the same type. But don't worry, these extras come with all the standard components and materials that you normally find in SketchUp.

SketchUp: Export Multiple Scene Images at Once

Exporting multiple Scene Images might be tedious without this trick.
Català - Castellano
From pushpullbar and a post by Torlai we find a solution to a common problem when working with a large number of scenes. What if I want to export easily a JPEG of each scene at once?
The 4 easy steps to follow are very simple:

1. Go to Window -> Model Info -> Animation -> uncheck the Scence Transitions box.
2. Go to the File menu -> Export -> Animation, set the file type to JPEG
3. Use the Options button to adjust the size of the images.
4. Export animation.

SketchUp: Hide All the Edges.

There is an easy way to hide all the edges of an object in SketchUp.I was recently working on a complex SketchUp file, and for the sake of the presentation I needed to hide all the edges of some very complex objects. I wondered why there is no option like Hide --> All edges. So we would keep the faces visible but the edges hidden.
The trick is simple. Remember that SketchUp has many different modes to show faces and edges. One of these modes is the wireframe mode. This will be or work around this problem.
We will edit the component or group that we want to have with hidden edges and we turn on the wireframe mode on. Then we will see only the edges, so we select all the geometry and go to Edit --> Hide. That simple, after that all the edges will be hidden. Switch on any mode that shows the faces and you will find your geometry with hidden edges.

SketchUp Plugins: Volume Calculator

Discover a plugin that will allow you to calculate volumes of objects.
Català - Castellano - Deutsch
There is a useful plugin for Sketchup called VolumeCalculator21.rb. It allows us to calculate the volume of an object. The only requirements are that it needs the object to be a group or component, and for maximum accuracy the geometry has to be clean. For clean geometry basically we need that each edge has two faces, no more no less, but that will ensure that the volume calculation is precise.
I tried it with basic geometry and the results were exact, when I tried it with very complex and not clean geometry, I got different results from time to time, so the importance of using clean geometry is very clear.
Still, I think it is a plugin worth having. To use it (after downloading the plugin and saving it to the plugins folder in SketchUp) select the group or component you want to know its volume, right click, and you will find an option called volume. Select that and you will get a dialog box that will ask you for which units you want to use and other options. It is very simple to use.
You can download the plugin here. Thanks to the author TGI.

AutoCAD: Meet the OSNAPs

Have you ever wondered what does each and every Osnap do? I did, and I tried to find out.
Castellano - Català
On my personal experience and according to what colleagues and friends tell me, it seems that none of us takes full advantage of all the OSNAPs available in AutoCAD. I think the way we work is mostly based on the way we always did, so we tent to not try new things, we like routine.
Once said that, I must admit that many times discovering a good way to use some of the OSNAPS makes your work flow improve considerably. So it is worth trying all of them and seeing what can they do to improve your AutoCAD proficiency. As a way of self discovering some of the OSNAPs I never use, and to share those that I think are the most useful, here is a compiled list of them with some quick description of what are they for and how they improve your drafting experience.
First a quick tip for those who don't know this. If you press Shift+Right Click on the drawing space, a contextual menu with the list of OSNAPs will appear ( See this previous post for more information about this). We will use this contextual menu (the picture on the left) as a list to describe each Osnap individually. The letters between parenthesis are the text entry/shortcut for those Osnaps

• Temporary Track Point (tt): If for any reason you like to work with Object Snap Tracking (OST) not active, this OSNAP will allow you to track from one point you select. It has a weird behaviour I have to say, because it seems not possible to use it twice in a row (I need to investigate more because so far it doesn't make sense)
• From (from): It allows you to click on a point and set the distance from that point you want to start or finish drawing. Almost impossible to use accurately if OST is Off, unless you use relative co-ordinates. It is actually useless in most situations because OST already allows you to do most of what "from" does (if someone knows any other use of this please don't hesitate to collaborate)
• Mid Between two points - (m2p): My favourite one, it allows you to snap on a point exactly in the middle of two given points. Very very useful and quite unknown since it doesn't appear in the Osnap Settings Dialog Box.
• Point Filters (.x .y .z): For those who used Microstation and miss that pressing the space bar to lock one of the Axis, this will make the trick. We can, for instance select to lock X, select the X coordinate that we want locked, and then choose any point. The resultant point will have the X we locked using this Osnap and the X and Z of the last selection. It can combine multiple axis locked, XY, XZ, YZ.
• Endpoint ( end ): One of the most basic ones. Not much is needed to mention since normally everyone works with this one permanently active. It will snap to one of the endpoints of an object, showing a square sign.
• Midpoint (mid): Another of the classics, it snaps to the midpoint of an object, it shows the triangle sign.
• Intersection (int): It snaps to the intersection of two objects. The objects need to have a real intersection, if no intersection is found between two objects that apparently are intersecting, check the Z values of this objects, since one or both might be not on Z=0. The sign is the X
  
• Apparent Intersection (app): What the previous osnap doesn't find as an intersection this one will. According to the active view it will ind the visual intersection between two objects. The sign is a square with an X inside.
• Extension (ext): It will let you choose any point on the extension of an arc or line.
• Centre (cen): Points to the center of an arc, circle or ellipse. The marker is a circle.
• Quadrant (qua): Points to 4 Points on a Circle or Ellipse. These 4 points depend on how was the UCS when this geometry was drawn and will always follow the direction of this original UCS. They would be the North South West and East coordinates of an Arc or Ellipse, being North where the Y axis is pointing. In Arcs or Portions of Ellipse they behave as if the Circle or Ellipse was complete, but only those that fall on the arc or portion o ellipse will be selectable. The sign is a square tilted 45 degrees.
• Tangent (tan): Allows to draw lines tangent to circles, arcs or ellipses. It doesn't work if we are drawing an arc. The sign is a circle with a line.
• Perpendicular (per): Finds the point that makes the line you are drawing perpendicular to the geometry you want. It can be used with lines, arcs, circles and ellipses. The sign is like an inverted T.
• Parallel (par): Only for lines. It allows you to draw a line parallel to another one. It is less intuitive to find out how to use it. You must select the first point, then chose Parallel Osnap if it's not permanently active, point on the line you want the new one to be parallel to. A Double line sign appears, then move the cursor away to where the parallel line should be. A dotted line appears and the parallel Osnap marker shows on the original line, click a second point.
• Node (nod): To snap on points or nodes. If you draw points using the POINT command, the only way to Snap o them is using "node" osnap. Also, when you use MEASURE or DIVIDE, points (nodes) will appear on the object (unless you use the [Block] option). The sign is a circle with an X.
  
• Insert (ins): With this object snap you can point to the insertion points of objects like Blocks or Text. The sign is a shape consisting of two squares.
• Nearest (Nea): Not to be used if you are trying to be precise, this osnap will select the closes point on an object, it can be useful for quick drawings and measurements, but it shouldn't be used for drawings requiring precision.
• None (non): If at some point we need to select a point and we don't want to use any osnap we can select the None Osnap that will turn them all off for one click. It would be the equivalent of pressing F3.

Photoshop: ICON Creation Plugin.

Customize your desktop icons by easy creating your own .ico filesI always feel writing a bit off topic when adding Photoshop topics here, but still I think they are worth it since in some way or another, most of us end up being involved working with Photoshop at some point. This Plugin might be even more off Topic than others. Still, I felt to share it here.

Some of us like to personalize our desktop and folders in a visual way that help us find the Icons quickly. I personally hate having a whole bunch of Icons that basically have only the image of a folder. I like to differentiate each important folder with a personalized icon, so when i need to access them either from my desktop or from the Quick Access bar it is easy and very visual.

Long time ago I tried a program call Microangelo, that worked pretty good, but it has only a 30 day free trial.

Since Photoshop is probably already installed in your machine, a much better option is a plugin for this program that allows you to save any image to an ICON (.ico) format. On this website you can download the ICON plugin for free. The plugin is under the GNU General Public License.

AutoCAD: Showing the XClip Frame

Sometimes is important to find out the frame that was used to clip an XREF. There is a system variable for that.If you want to know the frame you or someone else has used to Clip a Block or an Xref, there is a system variable that alllows you to do so.

The System variable XCLIPFRAME toggles between visible and invisible XClip boundaries. Being 0 for invisible and 1 for visible. Some important points to consider are:

• the Xclipframe will show on the same layer as the XREF or Block is.
  
• Xclip frames inside Xrefs will appear in the drawing regardless of those Xrefs having other Xrefs as overlays or Attachments. And there seems to be no way to modify that.

Personally is not a system variable that I use very often, usually only to check what was the intention when creating certaing clipping on Xrefs.
