Create header file

For the cad export a header file (as dxf or dwg) must be definied. For this either an existing file can be used or a new header file can be created.

A new header file is created as follows:

•Open your CAD program (e.g. ACAD).

•Save the empty file as dwg or dxf.

The version number depends on the version you are working with. I.e. if the CAD drawing is saved as Version 2011, it will work for 2011, 2012, and 2013, however not for older versions.
