While the file is being loaded, Arbortext IsoDraw CADprocess automatically examines the content as during import and begins converting it to its own data format.

When converting the file format, additional dialog boxes will appear (depending on the particular format) which allow you to control the data loading process. The dialog boxes are always opened with the settings made under Preferences in the Edit menu. With a number of formats such as IGES, VRML, and Wavefront, a structured conversion process is used for the 3D data. Because of this additional functionality, the placement of IGES format data is described below by way of example. All dialog boxes for these formats and the dialog boxes for the other two formats AutoCAD DWG and DXF are described in the Arbortext IsoDraw Data Exchange Reference.
