View Full Version : Rounding causing a critical error.

If you look at the perspective view, I'm trying to round the highlighted (in green) edge of the grey box to match the front edge of the yellow box. When I click the rounder tool nothing happens, so I pull up the numeric box and enter my values, accept and get the following error:
"L105: No polygons selected for Rounding. An error has occurred the may leave Modeler unstable. Please save work immediately."

I've tried selecting polygons and doing it, I've tried doing an edge bevel, then rounding it and I get the same result. I've tried making the rounder bigger and smaller...

The grey box is a box that had the corner cut out via Boolean and the inside corner was rounded.

Am I going about this the going way?

You could try reversing your operations. Round the grey box to match the yellow one (before boolean), then do a rounder on the corner of the box you will use to cut the corner off the grey box. Then do the boolean subtract.

Since you only have a few forum posts, I may be wrong, but I'm guessing you're new to LightWave. Having said that,
1. First off, EVERYONE will tell you Rounder is a bit quirky to work with.
2. After performing your boolean operation, did you merge points ("m" softkey)?
3. In the Rounder numeric panel, you must "activate" the tool, in the top-most tab.

eKalb: Yes I've tried doing the rounding first, which worked, and then trying to do the Boolean, but then the Boolean doesn't work.

Rudy: I've been using LightWave now for about 4 months. I come from a Rhino/ CAD background. After the Boolean I did merge all points, and made sure the rounder was active. I believe the "failure" has something to do with the Boolean and rounder commands not being able to work together so close to one another, but not sure.

I've recently went over Richard Culvers tutorial; http://lightwiki.com/wiki/Fundamentals_of_Subpatch_Modeling
as well as the free Lynda.com tut; http://www.lynda.com/home/Player.aspx?lpk4=81737&playChapter=False

and I'm attempting to create this another way.

Thank you for your responses.

I'm at work right now, so I don't have access to LightWave, but I see no reason why you shouldn't be able to get the results you're after. I will say, though, that I am used to using Rounder in point, rather than edge, edit mode. Thus, you should only have two points selected for that edge. If you've got more than two points, this could be an indication that your merge points action didn't complete as you expected, in which case you may have to weld some points.

Yeah, try a "fixed" merge at something small to catch any stray points.

Should work.

Rounder is awesome -once you know the rules it plays by. This is a simple operation you're trying to perform, so there's an issue somewhere. . .

I see two layers selected in your example. If you aren't doing so, use Rounder on a single layer.

1) Always Merge points as previously stated.
2) Use the Statistics panel (w) and make sure there are no single or two-point polys.
3) Unify Polys (I). Rounder won't work on redundant geometry.
4) View the layer in Wireframe mode to look for stray points.
5) Weld points that are too far apart (but still close together) that Merge misses. (The distance Merge Points uses can be manually adjusted too.)

Hope this helps,
