Section Plane UCS alignment

Tim Neumann

Is there a way to align the UCS with a section plane? See attached image. The marked plane is at an odd angle, so would be nice to have the option where the UCS sees the plane as an entity in which you could click on it and it realigns with it. In the same vein, how do you align a view with a section plane without

using the UCS? May not even be possible, checking my old Acad books and so far no answers.

When you double-click the section entity, its 'Clip Display' status will be enabled  (instead of the 'Live' status as in AutoCAD).
By default, the 'Use Lids' option of sections is On, which means that 3d solids that are intersected by the section plane, will get a temporary 'lid', which gives them a nicer look compared to looking at their innards.
Another nice thing about these lids is that you can snap to them...
So, now you execute the UCS command and snap to the lid geometry to define it...
