My workflow for developing energy models starts with creating a line drawing in AutoCAD from the plans that includes only those features which will have a significant impact on the energy performance results. I typically snap to a 1' grid to avoid too many small surfaces and/or small gaps or overlaps.
Anyhow, I had a colleague helping me out who did not quite understand the importance of precision in this whole process (which I understand was definitively failure on my part). So now I have a very large complex building outlined with an indeterminate number of slight offsets between spaces.
Does anyone have a clever way/extension to extrude these line drawing in sketchup without creating a bunch of super small spaces and/or gaps? or perhaps some way to edit the drawings in AutoCAD?
