3D Cross section view of an assembly?

[JamesLiu]

This is probably a silly question. I cannot figure out how to create a 3D cross section view in Assembly4 and A2Plus.

An example of 3D cross section view is as the following,

There is no way to do this exactly. You can define a clipping plane, but that doesn't keep the faces.

Std_ToggleClipPlane

The easiest way to simulate it is to add a big cube, and just cut the assembly with the cube.

It's pity that clipping plane loses the faces. It would be great to have an option to keep the face on clipping plane.

The boolean 'Cut' operation of Part WB works only between two shapes, but not on the assembly. I have to create the cut parts one by one, it is workable but tedious.

When using the Cut operation of PartDesign WB in Assembly4 model, it complains "PropertyLinkList does not support external links".

maybe a quick-hack, can you export the assembly to a mesh file (ex. step or stl) then do the boolean cut on the mesh?

Nope, the Linked parts of Assembly4 model cannot be exported into STL mesh or STEP.

Vielen Dank, Wilfried! The Cross-Section Macro works on part model smoothly, but fails on an Assembly4 model due to <class 'AttributeError'>: 'App.Part' object has no attribute 'Shape'.
