NURBS Loft

[APE Design Ctr]

Hi all,

I am having problems lofting a NURBS surface to create a solid. I have created one NURBS surface, and all I want to do is make a duplicate copy of it, make it 3/16" higher in the Z position, and then create a solid from those 2 surfaces.

I am trying everything, and cant get it to work

Anyone have any suggestions?

You have NURBS surfaces - the loft requires NURBS curves.

I'd approach the model a little different.

I'd draw the oval, then extrude it a little higher than the desired height (allow for trimming). Use subtract solids to cut the two holes through the model. Then, use the two NURBS surfaces to split, or section the model. Delete whatever exists outside of the necesary object.

thanks.

theres no option (like in Cinema 4d) to bridge open surfaces on a NURBS surface in VectorWorks is there?

Katie's method works, but VW can also provide what you want. Use the extract curves tool to get the edges of the big shapes. This makes a group of the two edges. Enter the group and use the loft tool, no rail mode - click each curve with the tool and you will see a bar between them. Pick "Ruled" in the dialog box and click the go button (or press Return). Repeat for each of the pairs of circles for the holes.
