Today’s beta build improves the extrude function in the Transformations panel.
Extruding by a negative value now works correctly*
Extruding from the “back” side of an object now works correctly*
The extruded distance for Transformation objects is now foreshortened — the Extrude and Move distance and direction now match
Extruding compound paths is now disabled, since it doesn’t work correctly anyway
Changing Draw Settings will tell Transformation objects to update
* At least it appears to work correctly in simple tests. There are still some rotations where the Z (depth) axis direction flips direction, which is also being studied now.
