View Full Version : Combining Triangles into 4-sided polys??

OK...stupid noob question here. How do I turn two selected triangles into a single 4-sided polygon? In Wings3D I would just select the two polys and then choose dissolve and have an instant 4 sided poly. Is there a similarily easy way to do it in C4D? My search results are not turning up anything yet...I may not have the correct terminology so I am unsure what to look for.

Thanks!

make sure to unclick the "evaluate angle" check box if your merging triangles that aren't exactly "flat"

But what if you have a cube and you knife one side. Then you get there triangles on the otherside, how can you get the other side to be like 2 nice quads?

new to this shit..

knife the entire shape, not only the side of the cube.

Sometime it's not so easy to do that, and you have to delete and recreate some poly, but it's not the cube problem.

Thanks Claudio :thumbsup:, but I suppose that this technique force me to use details where I have no needs. I'm wrong? Any other tips? I see a lot of meshes that are composed by most of quadrangles, but in cinema, using SDS, I find this quite difficult. The only technique that I have read about was Claudio's one. Thanks in advance for any reply. :)

Sometimes you just have to live with triangles, or else with some unnecessary polygons. You may want to pick up this plugin which is cheap but very effective:

I have a page on dealing with keeping a mesh quadrangular in C4D up at:

http://www.bmc.med.utoronto.ca/c4d/Addingres.html

It may help in dealing with C4D's no n-gon meshes...

Thanks AdamT and NWoolridge. :thumbsup:
Both advices are very useful. It is some time I was searching such stuff. :wavey:
