Detail drawings are created from a template drawing in the component_drawing_template model in the parts folder. The parts folder is located in:
C:\Users\Public\Documents\Autodesk\Parts
You can modify the template drawing to your own requirements.
During installation, the component_drawing_template model is put in the following folder:
C:\Program Files\Autodesk\PowerShapexxxxx\file\assembly
When you create hole schedules for an assembly for the first time, a copy of this model is automatically imported into the parts folder.
