Can I import multiple layers from AutoCAD into Slide?

Yes. DXF files can be imported into Slide using the File > Import > Import DXF option.

Once you select the dxf file to be imported the dxf import dialog will appear. The individual layers in the dxf file can be assigned to the different boundary types in Slide

Importing entities in DXF format is equivalent to adding them using the options within Slide (e.g. Add External Boundary etc.).  Therefore, the same rules apply, and model entities are automatically checked for validity, intersected if necessary, etc. Make sure that the external boundary is a closed 2D polyline, encompassing all material boundaries.

For a full description of importing dxf files in Slide see the Import DXF topic in the Online Help.
