apply textures to non-simple solids

[SUSANNA]

I must apply a texture on a wall (imported by autocad), which is not a simple parallelepiped, presents its merits divided into triangles (forgive profane language). I would like the texture to be applied to a face of the wall without changing cordinates in every triangle of surface. How do I do that?

select the wall and, from the list of modifiers, apply the one with name uvwmap

done, but I suppose it should be set somehow... in fact I launched the render and nothing changed... I read a mini course to understand something, but for now I did not take a spider from the hole: mad:

I spent the evening bidding with 3d studio with the uvw map...
the steps I make are these:
I create a wall
on the material editor imposed a multi subobject with 6 sub material that sticks to the 6 faces of the solid
then I select the solid- I go to mesh select, I select with poles a face, then I go to uvw map (the mapping is set to planar), allineo to y (the long side of the wall, which is the front of the wall, is aligned with the x but if they select the alignment with x it creates me a rectangle parallel to the thickness of the wall and not to the front that I fit at this point the orange rectangle is applied to my face, which is a rectangle, with the long x longer side (and the length and width values are rightly different). Now I go to awrap uvw, edit....and opens the window where I should see my rectangular face. It's a perfect square! Why? ? ? ?
I'll get a little bit of a headache.

My mother who wicks.... :

1. Why do you want to give multi subs to the faces of the wall? do you have different materials on each face?
2. if yes, then ok, when you apply the UVmap after the mesh select (I prefer the polyselect but not to mess up, prefix where you can the poly) if you do fit, you adapt the mapping to the size of the face to which it is applied, then it would suit you to have a seamless texture and apply the mapping of the texture dimmings to not have deformations
3. The unwrap for now let him lose... very convenient, but first it is better to understand the basic mapping
4. See this website http://www.ecosystem3d.com/corsi/moduloa/prog3dstudio.htm based on an old version of 3dstudio, but technically still current
