I know it's a broad topic, however, what are some best practices on creating reference planes & axis.
Thanks in advance,
what i do is draw a line in the existing model at the required location, go out of the sketch, insert a new plane using both the endpoints of that line as a reference, and third....an existing plane...this will give you a new plane.....
and very important.....DO NOT REMOVE the line at a later stage...this will kill the new plane and all the sketches,and extrusions on that plane....just HIDE the sketch
Just looked into your bio, and it seems you are an expert in 3D modeling.....Can't understand this question viewed in the light of your experience.....adding a new plane in Sw is quite a basic feature.....
