Vectorworks question

[CGN]

is it possible to use a spline as a trim edge?, and, are there any other splines types in vectorworks? the tool that i'm using to draw the spline is called "Nurbs curve tool".

Thanks for the help

I assume that you have VW 10 or later. Place a 2D object over the 3D surface and use the Project tool in the 3D palette. It has a trim mode that enables you to generate trimmed NURBS surfaces. You can also build the NURBS surface as a solid and then use the Subtract, Add, Intersect, etc tools in the Model menu.

Thanks Claes thanks for your help actually that was another question that I had, but I didn't explain myself correctly in the first one what I meant to ask is, for example if I draw the 2D profile of a boat, and my sheer and fairbody are sketches drawn with splines can a I use this spline to trim lines, circles or polylines?

Many thanks for the help

I assume that by trim you mean chop off and not align to curve / surface (as in TouchCAD).

Make user that the Spline is on top of the object to be trimmed (Tool menu -> Send -> to Front, etc if not) and then use Tool menu -> Clip Surface. Despite it's name this command also works with non-surface objects.

Thanks claes for your help, but still i can't make it work, and i have this message (see image), i will keep trying to found out what i'm doing wrong

Ah, it was a 3D Spline. I thought you meant a 2D Spline. Try this:

I forgot. If the lines are to be trimmed are 2D, select the 3D spline, Tool menu -> Convert copy to plygon - > No render in the dialog -> you now have a 2D representation of the 3D spline that you can use for trimming.

Thanks Claes i got it, and is working fine!, many thanks for your help
