arcs are objects?

[BobD]

Hello All,

I am trying to build a polyline which represents

the outline of a segment top door. It is composed of an arc and three lines. I need to take this polyline object and do an intersect suface against a grid of windows to then create

a segment top window grid.

I am creating the arc with arcbycenter and cannot find a way to create one polyline object with the four pieces. I have tried to do an addsurface of the arc, but it seems that arcbycenter does not create an object from which I could grab a handle.

The only vw arc command which creates a polyline is arcto, but I don't how to algorithmically calculate control points.

Any ideas out there?

Thanks,

BobD

Try Compose on the lines plus arc. If it gives you two pieces, do Add Surface on the results.

Hey Bob,

I was able to get a handle to the arcbycenter with LActLayer.

LNewObj didn't work though.

Andrew - thanks for the suggestion. I did a little research on NURBS and ended up calculating

the necessary control point locations and then used ArcTo. This resulted in the polyline object I needed.

Charles, thank you for the suggestion,

you're always on the money!

My apologies, I didn't notice this was the VectorScript section, and thus my answer wasn't VectorScript-related. (I check out the most recent posts list rather than going group by group.)
