So I’m faced again with the monotonous task of reconstructing a pre-exisiting building based on just plans/sections (This time for use in bim). In order to build the model correctly, I’ll need centerlines and center points of all elements. I’ve looked through the forum and found conversations about medial axes, and roof centerlines, but nothing really that directly addresses the problem at hand. The problem I have is that the wall polylines (taken from dwg) represent walls of different thicknesses and orientations, never perfectly perpendicular. Is there a method I’m missing? I realize I can just go through and draw centerlines manually, but with a multiple levels and multiple buildings, I’m hoping for a more automated solution.
