I've been struggling since I got here to do this correctly, but I haven't had much luck. I'm trying to make a proper rooftop, but I can never get the seems to line up. The prims I'm using are cubes. The isoscoles triangles are cubes with a topsize of zero, and the right trianges are cubes with a topsize of zero and topshear in the appropriate direction. Is there some math or a formula one of you math guys know that I can use to figure out the rotations I need to line up an isoscolese triange with right triangle such that the hypotenuse (on the right triangle) is seemless? Does that make sense?  Grazi PS. They are also flat (ie, have a thickness of 0.01 on the y) PSS. that isosceles triangle is actually an equilateral triangle.

I'm not much of an expert builder, but I've noticed there are certain problems with building using thicknesses as small as you indicate in your post.

Can't really help you here, but I've noticed problems with using pyramid shapes and textures. It seems like you can't get the angle right on the textures. They appear slanted and no amount of rotation corrects the problem.
I noticed a similar problem when, having been thwarted by the pyramid, i tried using cubes that were cut away into triangles.
So the short of it: I, too, am having the problem and have been unable to find a suitable workaround other than to not use triangular, texturized, pieces.

What do you mean by a 'proper roof'? I'm certain I could help with the maths, but i'm not certain what shape you are trying to achieve... maybe you could link to a picture/photo of something with a 'proper roof' so I know what you're after

I use quartered, hollowed cylinders, stretched on two axises and inverted inside-side upwards, to provide a sloped roof. The tricky part is making it thick enough so that I can overlap triangles inside them so that there are no holes.
You can check out my Varney shop for an example. A LM is in my profile
