A recent thread caused me to take a closer look at bounding boxes - and their use (or in this case - non use) by the inferencing engine.
It turns out that you can’t directly use bounding boxes edges, vertices, or faces as inferred origins or destinations of moves, rotates, scale, or tape measure operations.
This seems silly to me. SketchUp (SU) has obviously generated the bounding box as a displayable entity, but the generated
geometry pseudo geometry isn’t recognized by the inferencing engine. Why not?
I run into this problem often when using 3D warehouse components with rounded edges. I want to use the bounding box - usually a corner - as the point I “grab” in a move, yet without extra effort - I can’t!
@Box suggests hovering over an edge that is on the bounding box, then hovering over another edge which (along with the first) defines the corner of the bounding box, then a snap point is enabled at the corner. (see suggestion here)
@Coty points out that you can create guidelines to create a snapable inference point. (see here.)
And in the same post, @Coty suggests plugin alternatives.
My point is that it shouldn’t be this hard! SU has already created the bounding box. Surely adding the corners and edges - perhaps even faces - of a bounding box (when the whole group or component is the active selection) to the available inferences can’t be too hard!
