### Importing a Direct CAD File

Instead of translating CAD data into the internal CAD format of PC-DMIS, the Direct CAD file types are accessed directly. That is, the CAD data of these file types remains in its native format after being imported. Routines native to the CAD type are used for all calculations done on the CAD data. Accessing the CAD data directly eliminates problems that can occur because of translation inaccuracies or limitations.

The "Direct CAD Interfaces" documentation discusses importing Direct CAD Files in detail.
