Determine scale factors for rotated groups

tr=group.transformation.to_a xscale = Math::sqrt(tr[0]*tr[0]+tr[1]*tr[1]+tr[2]*tr[2]) yscale = Math::sqrt(tr[4]*tr[4]+tr[5]*tr[5]+tr[6]*tr[6]) zscale = Math::sqrt(tr[8]*tr[8]+tr[9]*tr[9]+tr[10]*tr[10])

Find area of scaled faces?

Got a fun puzzle today: I’m trying to find the area of the faces in a component that has been scaled. Naturally this distorts the materials on the component. First I search the model to find the particular faces I’m interested in, then I check to see if the parent component has been scaled. It it’s been scaled, I can’t trust the measurements, such as face.area. The parent of a Face is always a ComponentDefinition instead of a ComponentInstance. There is no way to access the entities in a Com…
