We have the wall depicted red with its location at Level 00 (z=0.0 m). It has one layer that is extended -0.3 m below Level 00.
When using Grasshopper to analyze the model, it is not recognized on Level 00.
Why are objects assigned to levels via their bounding geometry and not their location? Is there a way to keep a clean model and get correct Level assignment (meaning: I do not want to make an additional Level below Level 00 and cut the wall into pieces)?
