in order to inspect a model properly and be able to measure the thickness of a wall it is important that the section plane be aligned to the face of an object as oppose to manually rotating a section plane and trying to get it aligned.
We are pleased to announce the availability of our sectioning tools. Using the sectioning tool group you can create a section plane to clip the model. The default option is to align the clip plane to the face of an element you pick but other orientations are also available. You can place multiple section planes to clip the model for your needs.
