If you already have cartridges under Autocad, you can start from those (it avoids starting from a blank page !!).
Just replace the Text with properties related to the 3D model (see the Tutorials mentioned above).
Save basemaps (*.slddrt)
Save them as Document Template (*.drwdot)
Note: Remember to create 2 directories locally or on your network :
SW_Fonds of plan
SW_Modèles of documents
In the SolidWorks options, under "File Locations" assign these 2 directories, one for document templates, the other for basemaps.
Attached is our cartridge to show you the "phylosophy" of creation.
Note that you have to automate your cartridge as much as possible, everything or almost everything must be changed automatically (format, scale,......), you have to retrieve the 3D information (SolidWorks and custom properties).
