Description

Blender 3.5.0
SketchCAD master e7bf7d2
Ubuntu 20.04 ( stock Ubuntu, no kernel hacking or anything )
CPU: AMD FX(tm)-8150 Eight-Core Processor
GPU: Radeon R7 370

Stock Blender works Fine ( except for ray tracing which is just super slow )

When I start with the first use case for CAD Sketcher I do not see the square.

To reproduce:

1. Open blender.
2. Delete camera, light, cube
3. Press Ctrl+Shift+A
4. Select the X,Y plane ( Note, the YouTube video I saw will go into x,y plane view, but here I have to press number pad 1 to get it to look like on the YouTube vide, https://www.youtube.com/watch?v=1jNDLUDL0gc )
5. At this point I select the CAD Sketcher square
6. When I go to draw there is no visual feedback that I am drawing a square.
   Then, when I lift the mouse I only see pink small lines

I can try by click and dragging

I saw the square in black lines once upon a time. Now looks broken.

I can use some advice on how to erase the CAD Sketcher cache files so I can start from the beginning. Maybe some cache files changed format ?

I have installed CADSketcher from source following the guide.
And also run

blender --log-level -1  

But this does not give any leads to dig deeper.

Thanks

The content of the console would help a lot here.

Here is the blender log after repeating the steps to reproduce the error:

This might be a problem with the gpu where custom shaders are having an issue. Did you try the addon with previous blender versions?

[jeremyvillalobos]

Tested with blender 3.0 and have the same issues.

Then I tested 2.93.17, but for this version, I was not able to select one of the planes after pressing Ctrl+Shift+A

Let me know if there is a more specific version you want me to test.

Do you know of a thread for the custom shader issue so I can take a look ?

This is the log for the new error on 2.93.17. I think I saw somebody else with this error so I will try to find and link.

Ahh the addon is supported for blender versions 3.0 and beyond so the error you got woth 2.93 is expected behavior. But good to know that it's failing with 3.0 as well.

There were some changes to shaders recently, could you try again with the newest addon version?
