Hello Sim4Life community,
I'm trying to create a Petri dish model with a liquid solution, but I'm consistently failing with the Boolean Subtract operation.
Goal:
Petri Dish: Outer R=18mm, H=11mm. Needs a 1mm solid bottom and an open top.
Solution: R=17mm, H=10mm. Needs to fill the Petri's cavity, flush with the top edge.
Intended Object Setup (Z-ranges):
Outer Cylinder: Base at Z=0mm, Top at Z=11mm.
Inner Cylinder (for subtraction): Base at Z=1mm, Top at Z=10.9mm (Height=9.9mm).
Solution Cylinder: Base at Z=1mm, Top at Z=11mm.
My Problem:
When performing Boolean > Subtract (selecting Outer Cylinder first, then Inner Cylinder):
The result is either completely empty in 3D space or a flat "disk" (no bowl shape).
This happens despite the Sim4Life tutorial stating the operation subtracts from the first selected object.
Key Questions:
Why does Subtract fail like this (empty/disk)? Is there a common issue with precisely aligned surfaces (e.g., Z=10.9mm vs Z=11mm for cylinder tops)?
