Little problem creating a solid from surfaces?!

Anonymous — Sat, 12 May 2018 14:28:40 GMT

Hello to all who read this!

I am relatively new to Autocad and until now was able to solve appearing problems without help. But atm I am really stuck. I want to design a reflector for a COB LED and simple solids just didn't cut it. So I used surfaces for the first time.

Here is where I am struggling: I designed the outer and the inner shell for the base of the reflector, so far so good. Now I try to close the gaps at top & bottom to convert the model to a 3d printable solid. I was partially succesful but its not possible to use the sculpt-command in order to convert the model into a solid. If anyone can give me a hint, I would be very happy. Thx in advance, have a nice day, Robert Zimmermann.

Result in attached dwg.

Steps in screencast.

In short words:
- The outer surfaces get a "ceil" and a "floor", using the surfpatch command.
- command Surfsculpt to get 3D-Solid
- The inner surfaces union to one surface (union command)
- slice the solid created above with this surface to remove the inner volumen.

Thank you so much for taking your time and me by the hand. Now it is so obvious to me, sometimes all the possibilities are a bit overwhelming for my brain. 1 hour ago I was frustrated, now I am very happy and able to proceed with the project...
