Thank's for help. I corrected my mistake. Now It solve OK.

I have an issue when using Linkbranch. My Spacemouse Compact is erratic when rotating around 1 axis. Works and has worked with official 0.19 versions without any issues.

Encountered an issue with Assembly 3 today. I've attached some screen shots below. I created an assembly with two sub assemblies. I constrained the parts using the "Plane Coincident" constraint. The Elements used for the constraint are two sketch circles within each assembly. They can be seen in the first screen shot as the green circles along the axis of the hinge. When I set Lock Angle constraint of the Plane Coincident constraint the "True" and set the angle to 0 the first screen shot illustrates the result. When I change the angle to -45, the result is illustrated with the second screen shot. When I change the angle to -90, the result is illustrated with the third screen shot. The third screen shot appears to be incorrect. The top cover should be at a right angle to the bottom but it appears to have the same orientation as when the angle is set to 0.

Has anyone noticed anything unusual about adjusting the Angle when using the Plane Coincident constraint? Perhaps I am misunderstanding how this property is intended to be used?

Any constraints that involves angle is troublesome in most algebraic based solvers, because they are actually constraining the cosine value of the angle. So there are four angles that satisfy the constraint.

You can try replacing the Plane Coincident with the Attachment constraint. The attachment constraint is special, as it does not rely on the algebraic solver. It simply copies the placement of one part from the other. You can adjust the Offset property of either of the constraining Element to get the designed angle. Be aware though, asm3 may decide to auto convert the Attachment constraint to a Plane Coincidence if the part is indirectly constrained to some non-fixed part. For example, if a part is attached to another part that has an axial constraint. You'll be fine if the chain of parts contains only Lock and Attachment constraints.

I just tried my own Spacemouse Compact on Windows. It seems working fine. I didn't modify any space mouse related code from upstream. Maybe it's the upstream that did some changes, as it seems that your upstream download is slightly older. Maybe you try updating the space mouse driver and see. I just made a fresh install of the driver before trying.

I'm having a bit of a problem recovering a file that I used as a path finder for ways of modelling "in context"/reverse engineer a shape. It contains a major assembly in the SU30_Assembly file comprised of more sub assemblies. While working with the file and with no cyclic reference errors till that point FC crashed. Upon reopening I get this error message.

If I dismiss the error message and load one of the sub assembly files like Cannopy_Assembly and try a recompute/refresh FC will always crash with this mesage:

I've just started learning the assembly 3 workbench and am using 0.19. Is it correct to assume that there's no big issues or should I really be using RT's linkstage3 branch. I'm fairly new to Freecad and don't want to venture out of the box too much if I can help it

And I'd also like to extend a big thank you to jpg87 for his excellent site on learning assembly 3. It's helping me get my head around the concepts.

There is some problem with the bundled asm3 inside the upstream pre-built release. You can still use upstream FreeCAD if you want, but you'll need to manually clone my asm3 repo into your user directory. For Windows, it is located in c:\users\<your_user_name>\AppData\Roaming\FreeCAD\Mod\.

Hey guys. Can you please update the asm3 repo? Thanks!

Thanks for the heads up on the issues with the bundled asm3. I've downloaded your repo as a zip (I'm git illiterate) and will place in the Mod subdirectory you have indicated. I looked in that directory already and there's no asm3 files, but is that because the existing ones are are located elsewhere as it's included with the .19 system ?

Looking forward to learning this new workbench and thanks for your help !
