Section planes in the new 3D viewer

We have added section planes. Right click an element in the model and create a section plane from there. You can save several planes in the same view. To remove one, select the section plane and press Delete.

This works only in our new 3D viewer, and for now only for IFC files. Revit is coming.

If you have not tried the new viewer yet, you can turn it on under Project Settings as an opt in feature.
