I have a model with a lot of proprietary information in the internals of the equipment. The model has a number of piping interfaces where the equipment connects to the Plant. The client requires an Autocad file format from us to put into their Plant layout and the file size must be as small as possible so as not to slow their model down.
In the past I have exported to a step file and then imported that file into Autocad, but I don't believe this is the correct solution for my requirements.
Are their certain options in the export settings that I should be using?
Set up your view with only the parts you want to export displayed then
use the 'Export Displayed Only' option when creating the step file.
Alternatively you could look at using simplified assemblies.
Have you tried using the Simplify Visible Faces command? Depending on the shape of your assembly this might work well for you.
Once you simplify the model (which copies all the visible surfaces from the parts to the assembly,) you can right click on the simplified assembly, and select Save As.
