Assembly 4 can't update assembly after modifying part

Post by neutronstar »

Hello, I'm a FreeCAD noob coming from SolidWorks and Fusion360. I'm using Assembly 4 to connect two parts and I'm having trouble updating the assembly when I change a dimension of one of the parts. The second part should move when I change the dimension but it stays in place. The first part is called "palm" and it's the large one that's fixed in place. The second part is called "servo". The dimension I'm changing is called palmSize under the palm model's first sketch. (75mm to 68mm)

Before I change the part dimension:

After I shrink it:

Clicking the rebuild button that looks like a Rubik's cube while in the Assembly 4 workbench does nothing.

The palm's LCS "LCS_servo1" moves with the part shrink as expected, but the servo's LCS "LCS_1" does not come with it even though they were supposed to be connected.

Any help would be greatly appreciated :D

My system:
OS: Debian 11
FreeCad: 0.19.2
Assembly4: 0.10.7

the "servo" part is broken, "BaseFeature" is not set (your probably copied something from another file).

Yes, I copied the servo from a .stp file. I'm not sure how it got broken, but I deleted the "servo" file and started again. I copied the .stp file into the new "servo" file like this:
