I have done o lot of things with MOI3d in the last year, and I love it. Also the hints in this forum are very valuable for me.

But now I am at a point, where I need some help from the experts. If I missed the right forum entry, please apologize.


We want to print a two part laminating form for a engine nacelle for a new plane of a friend of mine.

I spent hours to model it, I tried loft, sweep, combination of solids and so on. At the end I succeeded with the network function. And after some more hours I also got a planar front plate and glued everything together. When I saw the word "solid" and found no naked edges, I thought, my problem are served, but they aren't yet.

- I want to cut out the wing connection and the exhaust part (green lines), but no boolean or trimming option works. In part 2 I tried as a test several boolean Operations (blue lines and the ball). I am able to shoot a hole, when it is totally inside the the solid, but other ways not. I am also not able to perform a boolean or trimming operation between the test ball and the solid or between the extruded solid. Why does this not work? I thought, a solid is a solid, isn't it?

- At last we want to generate a shell (3 or 4 mm, the outer side needs not to be exact). But the offset and shell function seems to be be limited (no constant angle or no way to generate a closed solid or a valuable surface). I wound like to have more options here. In former times, I played a little bit with Rhino, wasn't there a drape function, which generates a very lose coupled but closed area? I also thought, scaling the solid, an subtracting the unscaled part and yield as result a shell. How would you come around with this problem, which arise quite often?

Thank you for your advice in advance.

P.S.: I use the October beta version of MIO3d.
