Booleans that stay live

In a lot of tools, a boolean is a one-way door. You union two shapes and the originals are gone.

Sources stay sources

In Varial, the result of a union, subtract, intersect, or exclude remembers the shapes it came from. Move or reshape a source and the result rebuilds.

One step in history

A rebuild is folded into the edit that caused it. Undo once and you are back where you were, not halfway through a rebuild.

Warnings before you ship

If a source goes missing, Varial tells you, and it will warn you again before you package the file.
