NURBS Curve Direction Arrows

[Bruce Kieffer]

How do I see the direction arrows on a NURBS curve. I've been trying to loft all day. I see no arrows. This is a screen shot from the VW lofting video.

Before you use the loft tool, select your NURBS curves and check 'show direction' in the OIP, then when you use the loft tool and cycle through your curves, the direction will display.

@Bruce KiefferHi, have you been able to complete a loft or have you still been unsuccessful??

Have you converted all your shapes to Nurbs??

Got it. Show direction has to be checked on as you pointed out.

Here's what I want to loft, but I'm not having any luck.

I need to make this pull.

If you place the path snapped along the side of the profile objects, does it behave differently?

[Bruce Kieffer]

Yes, but the results are not symmetrical. One side is concave, the other convex. I will try one other way and see if that works. Is there a way to do a multiple extrude along path?

 

I'm moving this question to the solid modeling section of the community board.

Bruce,

I played around with this and I'm not sure the VW Loft Tool is actually capable of making it (I stand to be corrected by @Benson Shawwho is the VW NURBS master). I also tried the same shapes in Rhino for comparison. Rhino has so many more options when creating the same shape using the Sweep1 or Loft commands. I've attached my results.

I've personally never had much luck with the VW Loft using a single rail curve and multiple profiles. I know there's a wishlist item for improving the Loft Tool, perhaps this thread should be included with that submission. A drawer pull like this is a pretty common piece of hardware to draw.
