The adjustments and the adding of new blocks in the header file can be performed according to two variants:

1. Extending an existing header file

2. Create a new header file.

 

To create a new header file, following steps are required:

•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, 2013 and 2018, however not for older versions.
