Is there a CAD-System, which has an API and allows to use the API without the GUI (just using the Core). The CAD-System API should be able to:
- load multiple 3d-models
- change parameters of loaded models
- set references/mates/constraints between parts/assemblies
- create dxf from assembly/part
- add dimensions to dxf
important: would be really nice if it would be useable without the user interface.
