Bas Vellekoop Posted November 1, 2018 Share Posted November 1, 2018 Hi guys, Is there a possible modeling technique in which it is possible to fillet the 2 edges of these nurbs surfaces and give them a radius of lets say 10mm? @Jim Wilson You maybe any suggestion? fillet edges.vwx Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted November 1, 2018 Vectorworks, Inc Employee Share Posted November 1, 2018 Do you mean something like this? I may have misunderstood which edge/direction you were looking for: fillet edges - JimEdit.vwx 1 Quote Link to comment
zoomer Posted November 1, 2018 Share Posted November 1, 2018 Well, in Microstation's implementation of Parasolid from a decade or more ago you would find such in Surface Tools. If in VW there is no way to combine/stich both Surfaces and apply the fillet Tool in any way, in this special case it looks like a simple extruded Profile so far. Maybe the Fillet Tool would work on a simple 2D-ish Extrude ? Another option would be SubD with "helper Edges" to control the Radius of that bevelled Edge and finally converting back to NURBS if it should get more of a free form later. (Can test as VW is rendering) Quote Link to comment

If thats what hes going for, but didnt want the FINAL to be flat, its always possible to extract the bent/filleted surfaces and then youll be back to NURBS surfaces with no thickness. However, I shelled the original NURBS outward, which would make the resulting extract from this a bit too large, had i shelled them inward the exterior face would have maintained its original dimensions.

Bas Vellekoop Posted November 1, 2018 Author Share Posted November 1, 2018 (edited) a very fast sketch 🙂 Hope this explains what i want 🙂 @Jim Wilson @zoomer I`m able to do it is the following way, Shell the nurbs surfaces, fillet the edges, and then extract the inner surfaces again and shell them again.

Vectorworks, Inc Employee PVA - Admin Posted November 1, 2018 Vectorworks, Inc Employee Share Posted November 1, 2018 Ahh I see now, much tougher. Especially defining a particular fillet since it curves in 3 axes, I'll poke at it some more and see what I get. Quote Link to comment

Especially defining a particular fillet since it curves in 3 axes, I'll poke at it some more and see what I get. Yeah I know, but when possible very nice. The way i did it now is through a detour. I would be beter if it was possible on the nurbs sufaces. I thought i was maybe possible with the fillet tool from 2d pallet. I thought it worked on nurbs curves as well, but not sure.

zoomer Posted November 1, 2018 Share Posted November 1, 2018 Hmmh, so to create the whole thing from a Generic Solid first, which has a stacked Body form so you can get your "Profile Shape" by carefully using Fillet Tool, (Like to get your single Arc by filleting 2 Edges until they meet and such) Subtracting a Volume from that vertical Edge, (so it looks like a bended Sheet Metall Body) Finally Extract the Faces again ?

zoomer Posted November 1, 2018 Share Posted November 1, 2018 Sorry to bring other Tools into play but I think if you are doing such things more often in the future, for me it looks like that, as a companion to VW : https://www.bricsys.com/en-intl/sheetmetal/ Quote Link to comment

Bas Vellekoop Posted November 1, 2018 Author Share Posted November 1, 2018 This is how i do it now. Bit of a detour. @zoomer I download the bricsys but i was very quickly back in vectorworks 🙂 @Kevin McAllister It is not possible to fillet the edge wit h this command to my knowledge. 1 Quote Link to comment
zoomer Posted November 1, 2018 Share Posted November 1, 2018 (edited) For the first part, for me works well : - Create an Arc + a Line - Compose - Extrude - Apply Fillet Tool for the Edge Of course I could have created a Polyline in one go for the Profile to extrude. But it is nice that VW Fillet works on 2D Extrusions .... Edited November 1, 2018 by zoomer 1 Quote Link to comment
zoomer Posted November 1, 2018 Share Posted November 1, 2018 EDIT OK, asking for that thing above to convert into a SubD - was too much. And I don't know really what I can do with 3 separate NURBSies when converted. Quote Link to comment

You could then draw the angled edges and rounded corners on the flat surface and trim them off using the Project tool. Kevin Quote Link to comment
zoomer Posted November 1, 2018 Share Posted November 1, 2018 (edited) I read that such 2D-ish Objects could be cut by 3D Solids too, never tried. And the Eraser and Cutter Tool often do things in 3D that you would not expect too. But I think these 2D-ish are a bit of a blind alley. When converted to Solid it seems to destroy the roundness and make it polygonal. At least when I Thicken it with the Shell Tool. One side stays round, the other side gets polygonal. Just like in the past when I cut my Cylinder Columns from a Floor Solid. As soon as edited the round wholes got Mesh-y Edited November 1, 2018 by zoomer Quote Link to comment

zoomer Posted November 1, 2018 Share Posted November 1, 2018 Yes, staying 2D as long as possible for me seems to be always a good idea. Quote Link to comment
