If you need to avoid the triangulation, try .obj. It also has the advantage of being fairly ubiquitous.

And the company I send the models to, do need them in 3DS. Don't know why don't they move to .KMZ

As far as im aware the 3ds format can only handle triangles, os your model will inveitably become triangulated if you export to .3ds.

What puzzles me is why does it do it randomly, only on some of the faces. I tried exporting to .obj with the same result. When I open it with a 3DS viewer, some of the the faces are perfect rectangles, but others are made by these triangles. This is really exasperating me. Before sending the results, now I have to open every model with a 3DS editor and erase those lines one by one

Hi all. After many months learning a lot from this forum, it's time to ask, as I haven't found any solution for my problem.

I need to send some 3DS models for job. I don't use 3DS at all, as I do all my work with SU. My problem is when exporting to 3DS. Example: when I export a cube to 3DS (6 faces) it divides every face into 2 triangles, resulting 12 faces. I really don't know how to avoid this and it is very important for my job. Any idea?

In the next link, you can see an example. On the left, the SU model. On the right, the exported 3DS file. This matter only happens on some faces, as you can see.

Thanks in advance and sorry for my english
