1. After the Boolean operation, you can add the rounding function, automatically round the corners, and set the size of the rounded corners.
2. Curves can be used to divide edges on polygons, and they can be routed automatically, and can quickly select the faces in the curve. This way, the modeling efficiency of hard-edged faces can be improved a lot. You can refer to MODO software, their modeling efficiency is too fast , I hope you can improve the speed of mechanical modeling.
3. Maya polygon modeling has not made much progress in the efficiency of hard-edged surface modeling. Recently, MODO software is much stronger than Maya in polygon modeling. I hope MAYA can develop hard-surface polygon modeling functions that are more efficient than MODO. MAYA is too slow to do hard surface modeling.
