6. Create new layers: You will find that there is usually only one layer within the dwg. For
later use, its best to create a series of new layers (I name them to correspond with the material I will later
apply in Revit), for instance, "Toyota paintwork", "Toyota glass", "Toyota wheels" etc. For ease of viewing, ensure
these have all different colours (the actual colour is irrelevant unless you are very fussy!).
7. Once the layers are created (normally no more than seven or eight are needed), you need to
pick the individual meshes, one at a time and assign them to those layers. I find it easiest to start with all
layers switched off except for the layer the object started in. Then, for example, select the main bodywork , and
assign the new layer to it. You will see it then disappears (as the new layer it has gone on to was switched off)
thus just leaving the objects that you still need to assign a layer to.

8. Once all the objects have disappeared (it takes a few minutes), switch everything back on
and take a look. Type "shade" to view it as a shaded object if you prefer. Try to see that your material
distribution matches that of the real object. (For many of the cars I have imported, I will check out the
manufacturer websites to see images of what material goes where on the real vehicle for an authentic
visualisation). Save the file, close AutoCAD.
