I need to do some work, I need the following features.
1. I would like to call CAD file to calculate the area, and automate repetitive tasks such as marking.
2. I want to save the output as dwg, dxf file.
3. Can I load dwg, dxf files?
The PLUGIN can only import files, not export. The main reason is that we forbid in our EULA the use of our Plugin as a batch solution to process files.
Concerning your third point, here is the list of all file formats supported by PiXYZ.
