I am trying to create a truck door with a hole for the window.

Tried and failed:

1. Lofting the 2 curves - failed

2. Projecting the window curve onto a planar trim (that defines the whole door) and then trimming - failed.

3. I cut rhe 2 curves into 4 pieces each to make a boundary or sort but as I got more than 4 I tried fillet and failed.

I am trying to create 2 curves (in pink) to loft

the zoomed window you see is what I try to Fillet - and fail and I tried intersecting and extending - everything fails !!!!

I haven't had this kind of thing in Rhino

I AM DESPERATE - Have I paid 2000 U$ for a piece of nurbs-amateur junk or am I doing it all wrong ?

Nurbs aren't mathematically inclined to putting holes in them... you may want to use polys, or if NURBS are required, perhaps try seperating the pieces. I'd have to see your reference to tell you where you might be able to.

Mike, Hi

That is exactly what I was try after failing with the hole - as you can see there are the small lines marked with yellow arrows - I sperated it into 4 areas - each to loft or boundary - but then, I failed.

This is a fantasy truck so no reference .

what I meant was instead of trying to make the door all in one continuous shape like that, perhaps make just the lower door portion by itself, and have the upside-down "U" frame of the window as a seperate piece... and don't even worry about trying to make them look seamless.

Or, use polys and put holes wherever you want. lol user added image

You gotta remember, Maya isn't just a nurbs program... it's got a lot of other stuff in there, too. user added image

Actually , I didI start the truck with polys and then decided I would like the cabin in Nurbs, take a look:

Well, I don't know anything about Filleting or anything else you said, but here is the way I would model a nurbs door. This is the easiest way in my opinion. The first image is your door made from a nurbs circle. It is one whole object with one isoparm traveling around the exterior edge, which might be helpful in some cases. This proceedure is accomplished by smoothing the poles of the circle with the Smooth tool in Edit Nurbs?Sculpt Surfaces Tool. This can be easily done in the top view. You then take each vertice and position it so that it is parrallel with all other vertices on an axis. This is probably the hardest and most complicated way to model a flat surface.

The second image illistrates your door made mostly from one single nurbs plane. You simply take the vertices and model a little at a time, inserting isoparms along the way to give you more to work with until you make the two ends of the plane meet. There is no way to stick or combine these two isoparms, so your only choice is to patch it. Create a plane (the green one in image 4), position it in between the two ends, and stich it.

There is another way as well, which caters to a door model that will be attached or stiched to other parts of the truck. As you can see in the third image, the door is made up of 4 nurbs planes or "patches." You can stich these together, then select exterior isoparms on specific patches to connect other parts of your truck to the door. Modeling a patch door can be done either by creating several plane, then positioning them into their proper places, or by modeling what you see in image 2, selecting several isoparms, then choosing Edit Nurbs> Detach Surfaces, THEN recombine the patches by stitching the isoparms together.

*whew* You probably didn'y understand a thing I just said did you? Read it over a few times. Anyway, I hope this helps in some way.
