[BUG] Generated geometry is incorrect and cannot be properly extruded using the solidify modifier about cad_sketcher HOT 10 OPEN

This is similar to my issue #440. I have reproduced this bug using points and lines, and changing the Mesh Curve Resolution to 1 did not "fix" it. The .zip contains the .blend file and a .txt file that describes the steps I used to create it.

I can create a cross shaft using two sketches - one a horizontal rectangle, the other a vertical rectangle, and then boolean UNION them together.
You MUST use the Point / Line approach if you encase the plus object (shaft) in a circle to get a bore because the two union'ed rectangles do not work.

i'm experience a similar issue (see sketch) with a bunch of holes in a flat plane . i tired the "trick" to see if different mesh curve resolutions would solve the issue but so far i'm unable to find one. the best i can tell it's an issue with face orientation so that the solidify is happening in the opposite direction indicated by the offset

This is a serious blocker. Anything aside from the simplest topology results in issues.

I seem to be able to manually work around the issue for now by extruding manually

A workaround that I documented on the Discord before is to remesh the object using the mesh to curve and fill curve nodes on geometry nodes, before Solidify,

I suspect that this happens due to the order of how the model was sketched and constrained, causing the creation of excess points with wrong rotations, when filling the shape. So don't use the built-in "Fill Shape option" or use object type "Curve", if this happens.

Hi @wipmate , @dtremain , @jmsunseri , @hlorus , I tried to reproduce your issues and found a solution that works and the reason causing the problem.

The problem comes from the fact that Fill Shape doesn’t work well with complex shapes. Don't know if adding/switching to bpy.ops.mesh.beauty_fill() in mesh converter could work better.

Solution:
-Update the sketches by unchecking Fill Shape.
-Exit the sketch.
-Duplicate your mesh (if you go back to sketch mode, the changes will be lost).
-Select the copied mesh, in Edit Mode (select everything with A) use ALT + F to fill. If you have complex geometry and ALT + F doesn’t work, create face "islands" manually.

I think it would be advisable to recommend using a step-by-step workflow:

-Sketch for basic geometries
-Sketch of shapes to use as booleans

@dtremain the attachment seems to be missing, you might have to post it on GitHub directly.

The error seems to be related to Blender 4.2.1 LTS. I didn't have a problem in 4.1.
