This is the first time I noticed that there was a Viacad section here on CNCZone. Shout out for mmoe who assisted me on the Bobcad forum a few months back by recommending this CAD package. It is a great value for the price and is much more intuitive for basic 3D work than BobCad.
I had a design change where I had to go from a pure symmetrical object to one that transitions from round to nearly square (see screen shot). Think of this as a bowl but I won't go into details about what it is exactly. My objective is to 3D print this, so I need an enclosed solid. For something produced from primitives, this is fairly straight forward in Viacad (I use version 8). Problem is that I had to create this by transitioning from a circle to a radiused square and then skin it. First I couldn't figure if it was even possible to skin it in Viacad, so I sent it to BobCad V25 where I was able to put a skin on it. It has some wrinkles but I can try a higher resolution (ie more transition rectangles) later if I get this basic concept to work.
So first question is 1) Should I be able to do all of this in Viacad? If so, how would you go about it. I couldn't figure it out from the surface utilities or find a tutorial/video on it.
Second question 2) Assuming you can't do this in Viacad, how would I go about properly closing my inner and outer shells so I can print this? I have two surfaces here and not a solid, so can't use solid add/subtract.
I'm attaching the screen shots and a zip file with the wireframe viacad file, the shell one is too big to upload.
