Circuit Studio Crashes When Creating Contents of Mesh Folder

larry_137

I have been having a problem with CS crashing when either adding a 3D object to a footprint or viewing the PCB in 3D. I have written several other discussions on this on Element 14. I think I have finally narrowed down where the problem is. CS crashes when it is creating the files that go into the Mesh directory. The location of this directory is given (and can be changed) on the General tab of the PCB page under System. Any operation that would create an entry for this directory causes CS to crash. I have tried running as Win 7, I have updated to Win 10 Pro 64. I have completely deleted and re-installed CS. I bought and installed a new graphics card (Radeon Pro WX 5100) that supports DirectX 12. None of these things has solved the problem. However, if I copy my project and load it onto a machine on which CS works (my laptop), when I open the project CS proceeds to mesh the components in the library/project and write them to the Mesh directory. If I copy the files in the Mesh directory back into the Mesh directory on the problem machine, everything works fine. I can load components, I can view the board in 3D (and it displays correctly) and CS appears to function normally. As long as I do not do an operation that requires a refresh of the Mesh directory, all is well. My system has an Intel Core i7 960 processor, 9 GB of RAM, Radeon Pro WX 5100 Graphics, 1T SSD main disk drive, and is running the latest version of Win 10 Pro 64 bit. I am hoping someone can figure this out, or if a new version of CS is in the works, that this will provide enough info to fix the problem.

  • Does your username on the problem machine have a space in it, by any chance?  I have a dim recollection of something similar happening a while back.

  • Well done tracking that down!

     

    FWIW my mesh directory (Preferences > PCB Editor > General > Mesh Dir) is given as:

    C:\Users\username\AppData\Local\Altium\CircuitStudio {44D4D589-96A6-4A60-A915-7BEFDDF7C186}\Mesh

    Never had issues with it or cause to change it, so thats the default directory for me.

     

    Could it be a write permissions problem?

    Antivirus?

    Yes, it does. A good point, but a year ago, I did a full PCB design through production release (board is now on the market) with no problems. At the time, I had Windows 7 64 bit, and an Nvidia K2200 graphics card that supported DirectX 11.0. Sometime around last fall, the same project suddenly started to have this meshing problem. I have upgraded to Win 10 Pro 64 bit and a new video card with DirectX 12.0 support to no benefit.

    Good suggestions. I tried moving the directory and then setting the permissions so that anybody could read/write. Still no luck. I turned off real time scanning and firewall (just because) with no happy outcome.

    Whoa! I spoke too fast. I turned off McAffee but forgot I also had Malwarebytes running. I turned of Malwarebytes and the meshing went through, at least on a single trial. Voltsandjolts you may have grabbed the gold ring. I want to be careful, I have thought I had solved this before, but that is a tremendous lead. Thanks!
