When opening a drawing file into Navisworks or Simulate and the objects or elements in the drawing are either wireframe, single line or just missing from the drawing. This is typically due to the drawing having some CadWorx objects in it. What you will need to do is contact CadWorx and request the version of object enabler that you will need and install that on your machine. If you have CadWorx on your machine you will still need to get the appropriate object enabler(s).
If you are not sure if the file contains any CadWorx elements in it look at the Navisworks scene statistics for any messages about the file. Do the following:
To view scene statistics
1. Click the Home tab and slide out the Project panel.
2. Click Scene Statistics.
