FrameWright can split GDL objects in 3D with the same simplicity as the standard ‘Split’ tool (below):

1. Draw a split line across the selected items
2. Click on the side to remain selected

As with rotation, all the split objects can still be individually edited (including further splitting and/or rotation) and no new GDL objects are created. Split objects can be sensibly stretched (see right), and hotspots are placed on all cut edges to enable segments to be easily clipped together.
