Hi,
how can this band merge on the middle?

127768

i think, it is a simple function on LW.
I mean not simple scale on middle, on comlpex geometry is so not possible.

Thanks,
Roland

This is not complex geometry so you should just scale this and merge point and delete the two point polys. On complex geo you could merge average points 2 by two...or split it in half and delete edges

Split middle polygons in half.
Remove unwanted edges around it.

I would select the top row of edges and from the Construct Tab use Dissolve loop. Then select the bottom row of points and then select one of the points on the middle row and select Align | To Last Point's Z from the Modify Tab.

Like this:

It will work only with flat geometry. Random rotate plane and try again.

Hi,
my first little solution:

127774

Is not the fastest way ;)


PS: "Dissolve Loop" is cool, for correct point position use AxisTranslate in ModifyTab. Thanks!

My solution using EasySplit (http://easysplit.trueart.eu) for cutting and SwiftEdgeLoop (http://www2.trueart.pl/?URIType=Directory&URI=Products/Plug-Ins/SwiftEdgeLoop) for dissolving edges on mass:

It takes 30 seconds.

After recording video I realized SwiftEdgeLoop doesn't require in this case to select all these polygons. Because these edges are closed edge loops by them self.

Well yes, obviously. I was just going on the first example image.

In the case of curved or detailed geometry (and without the need to purchase a third party plugin). I would select each set of points, in turn and run Weld Average (which I have setup as the shortcut CTRL+SHIFT+W to make it easier to select each time) and then in the Polygon Statistics Window (w) select and delete all 2 point polys (2 Vertices). This will pull your points in further, so a little tweaking maybe needed.

No need to select point pairs in turn..... :)

1) Select the poly loop (not the tris on the end.... but they won't be included if you hit "select loop" (or arrow key) anyway) 127777
2) Run Multi Merge Average (https://www.lightwave3d.com/assets/plugins/entry/multi-merge/) (there's even a percentage slider if you want the new seam not to be dead center) 127778
3) before dropping selection (they are now 2 point polys) Hit delete. 127779

Oh that's nice! And it works on curved/detailed geometry too. Nice one JoePoe.

Hmm, does this Carl Merritt have a website? He's got a lot of useful looking plugins up on the list.

Alas, it would appear that his site is dead http://www.m2estudios.com/plugins.html but his scripts are quite old now.

I can't write 'em, but I sure can find 'em :D

One little gotcha.... You can go straight to Multi Merge Average with the poly selection IF the polys were created in an orderly fashion.
If not created orderly, convert the selection to points and it should work fine.

...and there's also Weld Group Average (https://www.lightwave3d.com/assets/plugins/entry/cp_weldgroupaverage/) :hey:
(no slider flexibility here, but you save a click because there's no interface....same deal with order)
