This might arguably deserve to be in the building forum, but I'll try here first.
This will be difficult to explain as I do not know the proper terminology, so bear with me, please.
Let's say you make texture which is a simple grid of horizontal and vertical lines. Texture the large face of a 4x3x1 prim, rotated so that the face is flat and at 0 degrees rotation.
Now duplicate this prim and rotate the prim, say, 72 degrees CW.
The grid of the new prim is 72 degrees out from the original prim.
Now rotate the texture in the new prim, 72 degrees CCW, using the texture pane.
What you end up with is not a re-aligned grid, as I had hoped. The resulting texture is skewed, for lack of a better word. A quick check shows that it was caused by the prim not being a square. Lengthening the 3 meter side to 4 meters fixes the distortion.
Is there a way to avoid this distortion, assuming that the prim size cannot be changed?
Can I do in with the prim tools, or do I need to make a texture specifically for this prim? Would that even work?
Thanks in advance!

I *think* I understand. Use the texture repeats to increase/decrease the number of times the texture is shown on the face.
I think what is being said is that a grid on a tilted prim is tilted, and that to have the prim be tilted but the texture straight up/across you'd rotate the texture. To have the grid be squared use repeats. It's sort of a non-question if it's what I think it is. _____________________

Use planar mapping instead of default. This is one of the things it's for.

Also you may be interested to try unticking "Stretch textures."

To have the grid be squared use repeats. I'm not sure how repeats factor into your understanding of my obviously poor explanation of my problem. The distortion comes into play because the face of the prim is not square (the texture is square). The repeats fields do not change the distortion. _____________________

Ah, yes, Chosen - I almost said that but just wasn't sure. Thank you for that bit of info.

No? _____________________

Chosen Few! Thank you. That looks to be exactly what I need.
I've never even noticed that setting before. LOL. _____________________
