The Import tool is used to import geometry from a number of file formats (described here) into Impact. The tool is started from the File menu.
Select file to Import
Once the tool has started the Import form is displayed, and you can select the file to be imported.
Unless the Import/Export MTS is chosen automatically (see the Smart Match section on the CFF2 page of the Import Settings) the MTS form is displayed.
Depending on the Palette Mapping in the chosen MTS and the geometry in the imported drawing there may be some unresolved palette mappings. This is explained in the Impact Project section of the Import / Export Settings Palette Mapping page.
If necessary the Resolve Palette Mappings form is displayed.
