Hello, I came accros OpenSCAD few months ago, and I love its simplicity; Great job there!! I usually use the software to build parametric surface models that are supposed to be used later in a "Meshing" operation, and I would like to have an easy (& native) way to specify boundary patches in the STL file. For example, I would like inlet and outlet faces to have their own regions in the exported file. I'm currently using modes to do so, and when it's difficult, I import the generated STL into another tool and make needed chages. Is there any better way to achieve this? Can OpenSCAD store created objects somehow (I found no docs on this)? Thanks in advance.

Such has been requested and discussed a number of times, but doing so breaks the key operating model with quick preview and slow full render. The closest is to export a STL then import it and do CSG. ----- Admin - PM me if you need anything, or if I've done something stupid...
