How can ı change automotically stl file when ı changed sldprt file
Accepted answer

The STL file is generated from the sldprt. It has no connection with the sketches and features of the sldprt. It requires a completed sldprt with the STL generated only from the surfaces of the completed part file. As the sketch features are not part of the STL the sketches in a sldprt can't change the STL
