AutoCAD 2024's SCALE is a uniform 3D scale about the base point: every Z
and elevation scales about the base point's Z (the current ELEVATION for a
point given without one) and every thickness by the factor. cadcraft
scaled X and Y only. The JSON form also takes a Z with the base point.
OFFSET's copy now keeps the source's height: a line's end Zs, a circle's
or arc's centre Z, a polyline's elevation. A circle's or arc's copy has no
thickness and a polyline's keeps it, as AutoCAD makes them.
Grip scaling, ALIGN's scale option and MOCORO stay 2D: their base point is
often a grip or snapped point whose Z cadcraft doesn't keep.
