Figure frame
Sets the exact export crop on the canvas; its border and handles never appear in the exported figure.

A figure's crop determines which parts of a setup appear in a publication or presentation. It is a composition choice, separate from any optical aperture or physical enclosure shown in the drawing.
In OpticalSetup
Place a frame around the desired composition and resize its edges or corners. The frame controls the export bounds, while its own border and editing handles remain canvas-only. Leave room inside the crop for component names, probe readouts, and any beam endpoints you want to show.
The example frames a small lens bench. Resize the frame and export the scene to compare the crop. Light continues to propagate beyond the frame on the workbench.
The frame never clips traced rays or acts as an optical stop. Content outside its bounds can be omitted from the exported picture while still contributing to the simulation.
