Problem description

When attempting to set a zero distance joint between vertexes it fails to adjust the location.

After some experimentation it appears it is because the Std_Part object added (because Insert as Part is ticked) to the to the Part Extrude the Placement is not handled correctly.
If the Part Extrude is is linked with "Insert as Part" unticked, joints work as expected.

@PaddleStroke also concerning the distance joint

Can you please attach the files so I can test?
It seems the JCS is not positioning correctly.

[macdroid53]

• Create a new document
• Create a Part WB solid (Sketch and Extrude)
• Save
• Create a new document.
• Create a Part Design Body, Sketch, and Pad
• Save
• Create a new document
• Create an Assembly
• Save
• Click Insert link
• Tick "Insert as Part"
• Insert the the Body and Extrude from above files
• Attempt to add a Distance (or any) constraint

With source 36120, produces the same results as shown in movie earlier in this issue thread.

I gave instructions above on how to test.

[macdroid53]

Is this stalled?

[PaddleStroke]

@macdroid53 do not worry I will fix it. I have just not come to it yet.

[PaddleStroke]

I cannot produce this error (in my current branch at least). JCS are positioning correctly.

First is that I killed the 'insert as part' option that made little sense. But even recreating the same as with insert as part (basically it created a part and put the link in the part) I cannot reproduce the problem.

Now I'm not sure if this bug is fixed in my branch or if I have not reproduced the exact same file.

Please make sure to attach the file when you report a bug so that it removes uncertainty regarding it's reproduction.

Any chance you can try to reproduce this bug in my dev branch?
Thanks

I have no file that shows the issue. Once the file has been saved the behavior is different. I am happy to provide a file when it shows the issue...in this case there is none.

This image shows what I get after "Insert as part" is used and I attempt to make a constraint.

Note the vertex selected and the axis that is associated. This does not happen is the "Insert as part" is not used.

It does not happen if the file is closed and opened again (I just noticed this) (but, after reopening the file, attempting to create a constraint crashes FreeCAD.)

I'm happy to build your branch, unfortunately, I know how to build main, I know how to build a PR...but, I don't know how to get your dev branch source to build. Sorry.

@macdroid53 great thanks, it's a PR actually : #12406

[maxwxyz]

#12406 currently does not fix distance of 2 vertices with offset 0.
Also lines do not work:

[PaddleStroke]

@maxwxyz I have put a fix for distance 0 between 2 vertexes. Was there a stand alone issue for this problem?

[maxwxyz]

@PaddleStroke this one here

[PaddleStroke]

Ah right, I got confused because later @macdroid53 mentioned problem concerning all joints.
So anyway the initial problem of the issue is fixed. Distance of 0 between vertex is fixed.

I mentioned that because it didn't appear to be the joints but the way the Part container was added to the solid it "Insert as part" was active and the user moved the cursor before click to drop the solid.

This effected all joint types when "Insert as part" was active.
