Dev:Ref/Requests/Cross section modifier

Cross section modifier

Google Sketchup has a very nice cross section tool, which comes handy when creating buildings with furniture or FPS maps. See a demonstration here: [1]

Currently the boolean tools will treat closed meshes like solids, but cross section should treat them as hollow objects.

Another problem is that boolean modifiers take a lot of time to compute, on the other hand cross section doesn't have to be very accurate as it will not be in the final render. No need to compute cross section for small triangles, as they can simply be culled. (I mean it would be modifier that doesn't actually modify the mesh, only the preview image.)
