Are there any APIs officially from GRABCAD for bulk download
I wanted to use grabcad library with specific category for Deep learning project, can anyone suggest ways if we are allowed to do so. I wanted to use GRABCAD models to create my own database (for my usecase).
No, there is no API for that.
If your question is a request to do so, it seem like contactin GrabCAD directly would be your best option to understand what is feasible.
It seem that your proposition might create some problem regarding competition: easily downloading all available models on GrabCAD might just allow competitors to start off with GrabCAD Database.
