Hey everyone,     This is my first post here, and I was never forally trained on autocad, so please excuse me if I'm not using the proper terminology. I have surface that was given to me and I need to convert it to a solid in order to cut it on our CNC. The surface is very complex and I believe there may be some tiny gaps that are preventing me from converting it to a solid. I've been reading a lot of the forums and I've done the usual conversion techniques, such as the convert to solid command. I've also converted it to a mesh and tried converting it to a solid that way but no luck. Any advice would be great, Thanks!

Too bad your stuck with AutoCAD 2008 as you might have better luck using the SURFSCULPT command.  Then again, if there are gaps then your chances of success with any command are going to be slim to none.

Actually, we've recently been updated to Autocad 2013

Well, I was able to load my surface into Inventor and stich it together. After I exported it back into Autocad as a block reference I was able to explode it and it came out as a 3d solid. Now the only problem is that this 3d solid has about a zillion different points and is so complex that even trying to move it takes about 5 minutes.

Time to buy a new computer perhaps?What kind of file size are we talking here?What are your computer specs?

The file is 44.5 MB, my computer is a Dell 3.60 GHz processor 8 GB of RAM

Yeah, I could see why you would have problems.  What are you going to do about it?

Lol, I'm not really sure. I was trying to figure out how to smooth out the solid, or just somehow reduce the amount of grips, but I'm out of ideas now.

With the system you are currently running I think you will have your hands full.
