How to convert an AutoCAD model to a Sketchup model for Sefaira

There is a fairly easy approach to simplifying models from other 3D modeling software and getting them into Sketchup. Here is a step by step process for exporting an AutoCAD model and simplifying it in Sketchup in order to upload it to Concept.
Export the AutoCAD model as a .DWG file
Import the .DWG in Sketchup (a function available for free on Sketchup 7, but only in the Pro version of Sketchup 8)
Create a cross-sectional plane parallel to the ground in Sketchup
Lower the cross-section down to an elevation that isolates the building footprint while eliminating extraneous objects (structure, mullions, etc.)
Right click on the cross-section and 'Create Group from Slice'
Move the slice away from the original model and copy it
Create a new Sketchup model and paste the copied slice into it
Delete any extraneous lines from the building footprint and complete the polygon surface
Extrude the footprint up to the building height, and then modify the roof and windows as needed
