AutoCAD: List of Objects

The list of all the AutoCAD object types. Links to the different categories of objects and relevant posts about them.
Català - Castellano - Deutsch
Back in September I started the series "AutoCAD list of Objects". As the series is finished right now, I thought i would be good to have a main post that works as a directory for all of the posts of the series. So here are the links to all those posts.
Remember that you can access this typo of posts that work as a directory of the website by clicking on the "directory" link on the orange navigation bar on the header.

• List of 2D Objects
• List of 3D Objects
• List of Annotation Objects
• List of Reference Objects
• List of Dynamic Block Objects/Entities

If you find any missing objects, please don't hesitate to contact me and I'll add them on the right category. Thanks!!

AutoCAD: Updating Fields Automatically

A system variable controls how fields are updated, play with it if you are having trouble.
Català - Castellano - Deutsch
My post about using fields in dynamic blocks has aroused some comments (mostly on the spanish version of the post) about the fact that the field of the sample block does not update automatically. I set myself to find why was that and if there was a solution.
This is the block I am talking about.The idea is that when you stretch the dynamic block, the field that shows its width should stretch too. Unfortunately this seems to not be possible, as fields require at least a "REGEN" to be updated. The research let me to discover the FIELDEVAL system variable, that actually controls how fields are updated. This are the options on setting the value of this system variable:

• 0: Not updated
• 1: Updated on open
• 2: Updated on save
• 4: Updated on plot
• 8: Updated on use of ETRANSMIT
• 16: Updated on regeneration

At least I didn't waste my time completely...and you get to learn something new too.

SketchUp Plugin: Geometric Curve Smoothing

Another free form editing plugin for SketchUp. Who said sketchup could only handle boxy geometry??
Català - Castellano - Deutsch
Editing curves and so called free form geometry is something important when we want to design buildings that are something more than a set of boxy shapes. Slowly, the ruby programmers are coming with more and more plugins to do this, turning SketchUp slowly into a great tool, too, for free form modelling.
The latest one I came across with, is the Geometric Curve Smoothing. What it does is better explained on the video below.



The plugin is still under development (currently version 1.1 is out). You can download this version via the author's page.

SketchUp Plugins: Smart Push Pull

Push faces smartly with this plugin from a4chitect.
Català - Castellano - Deutsch
The standard push pull tool doesn't give us sometimes the results we want when the geometry we have is not formed by perpendicular faces. If we have oblique adjacent faces to the one we want to push/pull. Let's see an example of what I mean. On the following model, we want to push the face colored in orange.


The standard Push Pull tool only considers the selected face, regardless of what type of geometry is adjacent to that face. The result would be something like this.


But if what we want is that the push operation understands that there is an oblique face "touching" the face we are pushing, we need to use the SmartPushPull plugin created by a4chitect. This plugin will allow us to get the following result without the need of complicated cleanups.



The plugin is still under development, so I'll just post the link to the Sketchucation thread where you will be able to download it and get the newest versions as soon as they are published.
One of the things you will notice is that the current version v0.26 does not delete the original face and lines, but this can be partially solved by using the "delete coplanar edges" plugin, that we saw on a previous post at CAD-Addict.

Powerpoint: Batch Importing Images

How do you import at once a set of images into PowerPoint?
Català - Castellano - Deutsch
I have never talked about PowerPoint here in CAD-Addict because it always feels it is a bit off topic. But the truth is that PowerPoint (or any similar version like its pen source counterpart - OpenOffice's Impress) is an important tool involved on the CAD work-flow, as the final tool used to present most of what we've done with other programs. So expect once in a while to find some posts about it from now on, specially now that at school I am using it more and more for my presentations.
Today, just want to describe an easy way to batch insert images in Powerpoint. This is useful to create simple presentations. Once we have created our presentation sheets, we might want to import them into PowerPoint at once.
To do this, you simply need to go to the insert tab (Office 2007) and click on Photo Album. Click on "select picture from File/Disk" to search for the folder were you have stored your presentation drawings and simply select the ones you want to include in your presentation. See the dialog box you will be dealing with below.


You can choose the layout you want for the inserted images, normally, fit to slide is for the use of doing a presentation of drawings the most adequate, but you could play with the other options in case you need it.

AutoCAD: Extracting Data to Excel

Do you need to extract the object properties to an excel sheet? Easy, don't do it manually.
Català - Castellano - Deutsch
Sometimes we might need to get information of some of the objects exported to an Excel Sheet to do some further calculations there. A good way to automate this process if we have a lot of objects is to use the DATAEXTRACTION wizard.
To access it simply type DATAEXTRACTION and follow the instructions. You'll be able to select which objects you want to export data from (or alternatively all the objects on a drawing or several drawings, see below)


You can always select which properties of the objects you want exported (length, object type, layer, color, etc) making it simple to later differentiate the objects in Excel.



By default, Object Name and Count will also be exported. Object Count means that if you have 2 objects with their properties being identical (those that you are exporting), the exported excel sheet will only show 1 row, and a count of 2. Name, is basically the type of object. See the image with 5 lines, and the excel sheet obtained after exporting only the layer and length of the objects.



As you can see the lines with equal length and layer show only once in the table, with a count of 2. If we had included other properties in the export settings (like start X or start Y) the lines would not have been grouped because the data extracted would be different.

SketchUp: Easy Paint different Objects with Random colors

Need to paint a bunch of faces randomly? Don't do it manually, there is a plugin for that.
Català - Castellano - Deutsch
Chris Fullmer published a while ago the plugin clf_extrapolate_colors.rb that allows us to paint a bunch of faces with random colors. It is very easy to use and it allows a good level of control on the randomization process, i.e. which colors should appear more often, etc.
On the smustard page where you can download the plugin there is also a very useful video posted by Chris that explains more in depth what this plugin is capable of.

SketchUp 7.1 Released

New update available.
Català - Castellano - Deutsch
I am quite late on this, last weeks my access to internet has been less regular than desirable. In any case, a new update on SketchUp is out. Version 7.1 brings some new features, so far nothing impressive though for what I've seen from the videos posted at the Official Google SketchUp Blog. Judge by yourself.
New Tools in SU to model context

New Tools in Layout 2.1


As I said before, so far I am not impressed by this new features. What about you? Did any of you try them? Are they worh updating to 7.1?
