Armatures is a property of Structural elements, that holds, at the moment, only Rebars. In the future you could think of different kinds of armatures, so I made it a bit more generic. Actually I wonder if it shouldn't be called "reinforcement" instead...
StructuralSystem is a default name given to the structural system objects, that are created when you select an axis and a structural object.
The optional volume to be subtracted is this: when you insert a window into a wall, a default subtraction volume is calculated from the outer size of the window, that is then subtracted from the host wall. But windows have an extra property that allow you to set a custom object as the subtraction volume. This is the description string of that property.
The structural nodes are the nodes system we've started to implement some time ago, to be exported - one day- to pybar.
FYI it's quite easy to find a string in the source code:
Code: Select all
grep -r "The structural nodes of this element" src/Mod/
For the MeshToShape stuff, I don't have anything at hand right now, I think, but any model found on the sketchup 3d warehouse will do, just export it as collada from sketchup... But mesh to shape conversion is a tricky business... Even with totally impeccable, clean, solid, non-manifold meshes, sometimes it doesn't work completely well...
