Model A Lapbelt

Model A Lapbelt

Model A Lapbelt

(OP)
Imagine a seat in a movie theater, attached to the ends of the armrests of the seat is a lap/seat belt that connects one armrest to the other.  I don't do surfacing.. how do you suggest I model the webbing of the belt in a draped (slacked) position?

RE: Model A Lapbelt

I'd probably use splines to create your basic edges.  Use either a sweep or loft to connect the splines (edges) with what can be mostly a straight line, if the belt material is similar to an automobile seat belt (relatively rigid).  It depends how complicated your path needs to be--mostly smooth/straight or quite convoluted--as to whether a sweep or a loft would be simpler.

RE: Model A Lapbelt

Just curious, why don't you do surfaces. Because that seems to me the way to go with this and once you have th shape that you want all you have to do is thicken your surface and it becomes a solid.

RE: Model A Lapbelt

(OP)
I've been using SW since 96+, the companies and products that I have worked at/on have never required surface modeling, so I have never taken the time to learn.  My world revolves around simple prismatic shapes, configs, and sheet metal; a loft or swept here or there, and that's about it.

Jeff, I'll give your process a try.

RE: Model A Lapbelt

Post some images if you get part-way there and need some help.  Perhaps we can figure it out from there if necessary.

SHAME on you Mango...!

That there was some "tough love".
