CATSettings Pointers for CATIA Users

I'm starting to realize deleting the CATSettings fixes a whole bunch of strange issue in CATIA.
Recently had this problem in CATIA NC workbench:  cannot pick the start/stop points in Multi-Axis Curve Machining.  This only happens with his log-in on his computer; using his log-in on another computer works fine.  The points, in the machining operation window (where you pick other driving geometry) are shown as solid black dots.  Is this a Tools -> Options issue?  Un/Re-installing CATIA doesn't fix this either. V5R18SP7.  Everything else (as far as we can see) works fine.  Any ideas?

CATSetttings is probably the biggest quirk in CATIA V5. I made a screenshot of all my Tools/Options and anytime we go to another revision I recreate my CATSettings. Like many other people, I learned the hard way. Anytime something is acting strangely it usually ends up being the CATSettings.

A few other CATSettings pointers on this. Do not use the same settings folder for multiple versions (R18/R19), keep a back up copy of a clean start - they will get corrupt from time to time. When unpredictable things happen - example your picking issue, replace your settings with clean set. Re-installing Catia does not clean up your setttings directory. You can find your directory in C:\Documents and Settings\USER NAME\Application Data\DassaultSystemes.
In there I would create CATSettingsR18 and CATSettingsR19, to do this you need to modify in the Environment Editor the path in variable CATUserSettingsPath.

Theo Jansen Mechanism drawn in Matlab


For one on my classes this quarter we had to draw the Theo Jansen 12 bar mechanism in Matlab. To do this we had to calculate each angle based on the input angle which in the video is the red link connected to the black base link. This took over 100 lines of code in Matlab which took forever to figure out but in the end it was worth it. There will be more projects to come in the future. Feel free to comment if you have any questions or want to see my .m file for this!

Update on CATIA Train Model

I promise to do a complete "How to" later on, seeing as how this is the CAD Systems Help blog and I don't think I've done much to help other than show off my own work. Here is my progress after about 8 hours of work on the Locomotive 020T Decauville CATIA model, which I uploaded to my 3D Via page. What do you think?

AutoCAD to CATIA: Train CAD Model

I'm working on a new project where I am taking AutoCAD drawings of a steam locomotive and recreating it in 3D with CATIA. After about 4 hours of work here is the result (from 3D Via):

I will be writing a full how-to on this later so stay tuned!
