Can anyone tell me the trick to smoothing a curved surface after doing a boolean subtraction on it. I'm tired of going in and editing point by point to adjust the angles. The surface seems to have hills and valleys along the edges of the boolean subtraction. Help!!! Scott

Scott, you might try starting with objects that have more faces in them — this may help your boolean objects retain the shape(s) you are looking for. Tesselate them before booleaning. After the boolean operation, do some Surface/Smoothing/Object/Auto Smooth ops with varying degrees of smoothing to get the desired surface on your finished object. Use Optimize, or Gus's recently UL'ed real-time G-Shaded viewer to quickly check your model during the processes. -Alan

I've tried all of the above. It always comes back to point editing. Thanks! Scott

Scott, If you've been manually editing points I assume you've tried using auto-smoothing and you're not get the results you wish. Auto-smoothing is a best fit approach, but to get selected areas with a variety of angles smoothed appropriately I would suggest selecting the faces that you want smoothed together and detaching them. Then use auto-smooth for a best fit on that group, and then attach them back to the object. This can be time consuming as well but you have a greater degree of control and is not as time consuming as point editing on a complex mesh. There are ways that you can assign a face to a specific group but this can get messy with a complex mesh. Smoothing groups can overlap, which may or may not be what you want. Try detaching them, this works in most cases and if you need them to share a group you can assign the detached portion all at once. If you need to, you can then re-weld the vertices, just don't use auto-smooth again. <g> -JE

Yes! It never occured to me to detach them and auto-smooth. Thats definately easier than point editing. Many Many Thank! Scott Lunsford Tennessee Production Center, Inc.

Scott, It works really great on beveled edges too. Glad to help. -JE
