Hello All;
I have been trying to figure out how to do something in Lightwave 10 for quite some time and as it turns out my summer student (Who is using LW too) has been wondering the same thing though that he saw in a video tutorial.

Take a look at the circled area in the attachment below. I would like to know how to make that curved shape from presumably a straight edge that follows the contours of the sphere - some points need to be moved following the contours of the sphere.

My student who is using Lightwave this summer has wondered how to do a similar thing though instead of a Lunar habitat, he saw a video where the person moved some points along the contours of lines in a head model.

We both would be greatful if you could give us some tips and ideas about how to do this. Thank you very much.

You mean that you have ready geometry, and then want to project points or other less or more dense geometry on it, and slide?
Such tool is Push from TrueArt's Modeling Pack http://modelingpack.trueart.eu
When it's used with points already projected to background geometry, it's sliding them.
Check this video

to ensure it's what you want.

Is there any way to do this without a plug-in ? Basically, I want to move (or slide) a point along a line (or curve). That's an easier way to describe what I'm trying to do.

I located a free plug-in called DEdgeSlide which does pretty much what I'm trying to accomplish (Except with edges rather than points) though it doesn't work with LW 10 yet. However, it would be nice if there were some way to do this without a plug in.

Any suggestions ?

Thanks. Tim

If there would be built-in solution would we waste time writing such tools.. ?

Geez ... sorry I asked.

There is a free plug-in called PointMoveOnEdge.

You could create a spline that closely follows the path in question, then in Layout have the 'following' object just travel along the spline. I can't remember the command at the moment, but I've used it before.... long ago
