Video Transcript

This is Phil Cook at simply rhino and in this short video were going to look at the new shell polysurface command in rhinoceros3d 5.

Here you can see we have a model of a bottle, which is a closed polysurface and has some protruded areas and some recessed detail areas.

If we were to step back to Rhino3d 4.0 then the way we would have to create a shell from this model would be reasonably complex. We first of all have to delete this top area here, and then use the offset surface command to produce the b surface here I want to offset inwards by 1.4mm and then I’ll take a look at the result I get from this momentarily hiding the outer polysurface. In Rhino3d 4 as most of you know you get a series of separate surfaces and very often when you try to join these surfaces there will be a number of naked edges and so there is quite a lot of repair work that would need to be done to this and then the final operation would involve manually creating the top surface here between the inner and outer shells.

If we look at the same procedure in Rhino3d 5 now we can use the new command called Shell PolySurface. I select the thickness in this case 1.4mm and then I select the face that I want to delete, then I let the command run. The command takes a little while but when it has run you will see that it creates a nice inner shell for me. And if I just check the model you will see that I have no naked edges and i’ve got a completely closed manifold solid. If you just take a look inside here you can also see that the quality of the b surface that it creates here is quite good as well. This is going to be a big time saver for a lot of designers using Rhino v5.
