Hi All, I thought there was a way to have Lightwave select every other poly (see image).

What do you mean by "every other".. ?
If you want to select polygons which are between one polygon and other polygon, try Selection > Specialty > Select Path.

ps. I found inspiration from your post, to make plugin which will calculate area of selected polygon, and allow selecting polygons within tolerance +- range from it (if "area of poly +- tolerance from user" -> "select it").

Are you going to make an LScript? That would be great! I know you can do this in other 3d programs. So there is no way of currently doing this?

Use select Nth

I never make LScripts. I am writing C/C++ plugins exclusively..

Use select Nth

That won't help if somebody needs to select polygons with exact area +- some tolerance.

f.e. polygon has 1m^2 area, +-1 cm^2 tolerance. And instant update while playing with tolerance slider.

Cool! You really going to make one?

It looks to me like Select Nth Pattern will do exactly what Tony3D indicated he wanted to do in the original post. Looks like he's making a gear and wants to select every other polygon around the circumference of his disc to extrude the teeth.

To do so, select the entire outer polygons by selecting two adjacent ones and use right-arrow to complete the ring, then use Selection=>Speciality=>Select Nth Pattern with parameters 2,1, with the result:

You're right. Select two+ polygons in row, then Select Loop, and then Select n-th, will select every 2nd, every 3rd and so on. If that's what he initially wanted to do in OP. That's why I asked what he meant by "every other".. Select Path was also answer..
I started discussion about completely new tool in my post..

Yes, that works great! I saw that, but didn't understand how it worked! Thanks again!

I occaisionally wonder about the proper 'formula' or algorithm to use Select N to make arbitrary pattern selections. But usually it's just faster to use Selection Sets or Parts in combination w/Select N.
