I use solidworks 2014 and in addition to my job as a bar turner I also do violin making. I would like to make a 3D mold of a musical instrument bottom to be able to make the one if in 5-axis machining afterwards.
I would like to make in a rectangular platform a part of a sphere in a circle in the center of this platform.
I drew my rectangle on a thickness of 25mm and in the center a circle of 320mm, in which I would like to do a material removal with a radius of 1035mm. But how do you just remove material from the circle?
You take a plane passing through the axis of your circle 1 of 320mm.
You draw a circle 2 of R1035 on this plane + a line for construction with one end attached to circle 2. This end is at the meeting point with your circle 1.
Then a removal of material by revolution. And you should get what you want.
Or you draw your circle 2 R1035 + collinear construction line on your face of the rectangle + 320mm side for this line (which is the same as taking the diameter of your circle 1).
I did it differently because I couldn't do what I could explain. I have traced my half profile from the side, an axis of revolution and a boss per revolution, it is not rectangular but it is only an unimportant detail.
Another problem, on this famous mold, I drew my final flat outline , I drew a curve under my foreground and then using the surface-extrusion function I created the surface with the shape of my curve that we see underneath.
But if we look at the width direction it's straight, and I would like to similarly give a curve on the width, but how do I do that from my new surface?
