Slicing a solid with a surface

[hconel]

Hi,
I am trying to slice a cube with a surface. Solid is created by Pad command and surface is created by filling 4 spline edges.


I am expecting to get 2 bodies in the end and delete one. However, I was not able to achieve this via commands under Part workbench, Slice did not work.
Can you offer a workaround or point what I'm doing wrong?
Thanks in advance,
Huseyin

Hi Huseyin, welcome to the forum.
Please add your FreeCAD info as described in the IMPORTANT link above. Serious enhancements have been made to the slice commands in 0.18. You should try in that version the command "Slice apart", it works here out of the box.

Hi Huseyin

As Chrisb says posting the version you use helps, but your part works with the single surface if you use the 'slice apart' command in the PartWB, you will need the latest 0.18 version, see below gif. Really useful addition in 0.18.

It works in 0.17 as well, but you have to extract the parts yourself using a Part CompoundFilter.

There's another older school way from before surface booleans and not so reliant on versions or specialised tools: part extrude the surface beyond the cube and intersect extrusion and cube, then subtract extrusion from cube.

Hi
Without using Partdesign Wb, I propose this result
With more competent should get as well with Partdesign Wb
