Each of the splines in this screen grab represents the position of a metal tube. Is there an easy way to create the tubes, or am I stuck making and positioning cylinders? I know about rail extrudes, but I'd still have to position discs for each one.

Introducing TopMod. ta ta ta ta ta-taaaaa!!

Add some control edges on the tube parts, subdivide and done! :)

Layout > Surface Editor > Advanced > Render Outlines (check box on)

use negative line size, experiment with lines sizes

Thanks. The second one is pretty cool, but it looks like there's no actual geometry created. I'll try to figure out Topmod tomorrow. I looked at the site and figuring out how to install it made my head hurt.

It's portable...
Take the files into a folder, run the exec. tada :D

I like it has tessellations methods nowhere seen. And quite handy to make high genus models.

the negative line trick is rendering purpose only, it doesn´t create any actual geometry..so not sure that is what you really would want.

Top mod is cool, I had a lot of crashing with it though, so a little unstable at some times, but creating poly frames is cool, and you can create amazing shapes to print out too:)

Truss 2 will work but its 32 bit only.

And don't forget LWCad.

creating framework like topmod or truss? how?

LWCad can do the same thing as truss2. Convert the mesh to curve then use profiler. Attached is an example of a box with 3 segments per axis.

Correct, the negative size thing also does not work in reflections etc. if I recall.

Yeah, this is what I've done before knowing Topmod, also the first image shows the limitations of negative thickness.

So reflection works but if the thing is big enough you'll notice stepping in the shading. Transparency is even more fragile.

Personally where the negative thickness really shines is on wires, where having real geometry is dreadful heavy.
9.6 Render, so they don't have pespective:

I got to this point, but I'm not sure how to make them tubes rather than triangular cross sections. What do you mean by control edges?

Ah only know I noticed your post.
Control edges are the yellow edges added in the last frame of that picture. Otherwise when subdivision was activated the holes would not be rectangular but round.

In 11.5 reflections and perspective do work.

Transparency, Reflection and at certain distances diffuse. You can see the little balls. Modo as a nice way to tackle this with an option: Render with polygons and respective number of sides option. Plus this is made on curves, not 2 point-polys.

Anyway perspective is a great addition.

I've found that I could access all attributes in the surface editor.
I then tried the node editor.
Car-paint was no problem. So the surface possibilities are endless.
Perspective is fine as shown.
All this of course is native LW.

Thanks to Dana Burman for the initial find.
