AutoCAD: Select objects before running the Command

This is a common problem after having FATAL ERROR crashed. The settings go wrong and you can't select the object first. No worries, it has an easy solution
Català - Castellano - Deutsch
Norman asked me recently the following question:

My CAD had a fatal error.
Where I used to click on a command then an object (eg: select block then copy)
I now have to click on the button then select object (eg: click on copy then select the block)
Can anyone help me change this back?

This is a common problem that occurs after crashed. For some reason there is a system variable that goes nuts after the fatal errors.

This system variable is called PICKFIRST. It controls what is called the "noun-verb" behavior of AutoCAD. This is the logic behind the variable.

0 - Turns OFF PICKFIRST. Select objects after a command is invoked.
1 - Turns ON PICKFIRST. Select objects before or after a command is invoked.

I can't tell you why this happens, but at least now you know how to solve it.

SketchUp Plugins: Modeling Twisted Torus

Model Interesting Shapes with the Torus Plugin using the twisting function.
Català - Castellano - Deutsch
I recently posted about how to model basic shapes like Torus, Spheres and Ellipses with or without a Plugin. Although on the videos I showed you that the shapes can be done without plugins, I've been playing a bit more with the Torus plugin and it is quite useful.

The best fucntion is to me the possibility to model twisted torus. See with the following two images what can be done.




Te plugin can be download at the author's blog.

Autodesk Navisworks Freedom: Clash Detection Viewer

Download the Free Viewer for Navisworks.
Català - Castellano - Deutsch
I was working recently in a project where collision detection was needed to ensure that the work done by architects, structural engineers and MEP Engineers was fitting with each other. The program chosen to do this was Autodesk Navisworks.

As with almost all Autodesk Products, the license price is quite expensive (~$10,000). Luckily, only the consultant in charge of the clash and collision detection had to assume this license price. All other consultants could visualise the collisions detected using the free viewer, Navisworks Freedom.

Autodesk navisworks Freedom is the free counterpart to the expensive Autodesk Navisworks Manage. It allows to visualise the 3D Model and to see the collision markups created with Navisworks Mananage. For us, it was enough to have Navisworks Freedom installed in all relevant workstations and have only the Clash Detection Constultant do his job and to send us the file so each spacialty (Architecture, Structre, MEP...) could follow up on the markups and solve the issues.

You can download Navisworks Freedom here

New Beta Features at CAD Addict

New Site layout and some extra features to increase user participation
Català - Castellano - Deutsch
I've been doing some "controlling" of the site through my analytics thingy. I discovered less than 9% of visitors are using screen resolutions under 1152 pixels wide, so I decided to increasde the website layout width to better handle some new features I had been testing in the last weeks. If you are of that low 9%, I am sorry if this causes you some discomfort, but the site needs to evolve following the user trends.


CAD Addict Forum: I have been receiving an increasing amount of questions through the contact form. I've managed to answer almost all of them so far, but I might not be able to do it in the next months. For this reason I've set up a Forum where you can directly post your questions, and I can reply there or anyone else can help. This way, we will all benefit from the questions and answers instead of remaining a private thing between me and one of you.


Comments: For shorter comments, random stuff, off topic discussions,etc. I created a conversation page using Google Web Elements. Let's see if there is a need for this. You can comment using your Open Id login.

This is all pretty new, so please be patient if something doesn't work properly. And of course feel free to let me know what you think about it and if you have any suggestions to improve it.

Book: Constructing the Future: nD Modelling

A reference book for many scholars writing and researching about BIM. A must read to understand the full potential of BIM.
Català - Castellano - Deutsch
On my process to write my master thesis about BIM as a project management tool I found many scholars referencing this book in their papers so I decided to get a copy.

Constructing the Future: nD Modelling. Despite being a book published in 2006, it is worth reading, for it is very comprehensive in scope and deals with all aspects of Building Information Modeling, from its role as an Estimating tool, to its use for Construction Management or how to use it by Facility Managers. It also mentions the importance of International Foundation Classes for better cooperation, and many more aspects I would recommend you to discover by yourself.

There are many blogs out there that post tutorials about how to model complicated things using Revit, ArchiCAD or other BIM packages. To me what is more relevant about BIM is its potential as a Catalyst to change and improve the design and construction process. I think this book is key to understand this.

To get a copy for yourself click on any of the images below to buy it directly on amazon.

Sign your Documents in Acrobat

Use stamps to sign your document without the need of printing them and scanning them later.
Català - Castellano - Deutsch
Nowadays, more and more applications mean filling up forms and sending them electronically. Many people like to print those forms, fill them up, sign them, scan them and then send them back. I personally prefer to do a everything in my computer. It helps me keep track of my applications and to have a record of my documents, plus I think an applications typed in the computer looks more professional.

So this post is for those who like to do that. I normally download the application PDFs, use the typewriter to fill out the different fields and when it comes to signing the document I used to find a problem. Acrobat doesn't let you insert an image that easily. I have my signature scanned and I use it in word documents, but in PDFs is not that easy. I found the solution not so long ago.

Acrobat has a feature called stamps. You can set up a custom Stamp, and used a JPEG scanned version of your signature. To create a custom stamp see the image below, it is under Comments & markup.


Once you have the custom stamp created follow the same path but this time go to Sign Here (or whatever subcategory you used to save the custom stamp) and add the stamp, your signature, to the document. On the image below you can see the custom stamp with a random signature I found on the internet ready to be used.


That's it, now you can avoid completely to print your documents. For me it is not a question of beeing green, but a question of beeing practical, I move a lot, and sometimes work in coffee shops, I not always have a printer ready, so with this system I do not need to stop what I am doing to wait till I get access to a printer and a scanner.

Cheers

SketchUp: Drawing Torus, Spheres and Ellipses

Drawing Spheres, Torus and Ellipses is quite easy. There are some plugins though that make it even easier.
Català - Castellano - Deutsch
Some basic shapes like a Sphere, a Torus or an Ellipse are not included in the default tools in SketchUp. They all can be done quite easy without the need of a Plugin, but of course anything that speeds up the modleing process is more than welcome.

Here you can see a quick video showing how to model a Sphere, a Torus and an Ellipse in SketchUp with the standard tools.


As you can see, it is a pretty simple process. Still, some of you might want to have these tools directly accessible on the Draw menu. For this, Regular Polygon has created several Plugins, simply click on the links below to access the Plugin website and to download them.

• Sphere
• Torus
• Ellipse

They also have two plugins called Superellipse and Supperellipsoid (Sort of rectangle with rounded edges, or cube with rounded edges) for this one I don't see a some way to draw it easily with the standard tools, so here comes the link to the two of them.

• Superellipse
• Superellipsoid

My Parents House in SketchUp

This is just a post to share some work with familyCatalà - Castellano - Deutsch
Long ago I modeled my parents house in SketchUp. I used this building to learn basic and not so basic modeling technics. No one would call the building an architectural masterpiece, but its a bit illogical and random architecture made it a good bulilding to learn SketchUp (and other programs too).

I already used this same model long ago when posting about the SketchUp Web Exporter (unfortunately now the post is not working properly because of the transition from google pages to google sites)

So here come some screenshots of the building.

SketchUp Plugins: Soft Selection Plugin

Add vertexes and perform Soft selection operations in SketchUp
Català - Castellano - Deutsch
Thomthom has a very interesting plugin called Vertex Tools to perform Soft selection of vertex. It is not free (it costs $20) but if you need to perform this sort of operation it will be worth paying for it.
On a previous post about Rhino, I already explained what soft selection is and what we use it for. Below you can see a video explaining the functionality of the Vertex tools Plugin.
