Mass: Divide surface gives different types of division

[kichappa]

I have created this mass to make the exterior of a building. I intend to make it a triangular pattern wall.

I have 2 triangles on the same mass. Yet, when I "divide surface" them, I get two different kinds of division. Further, if I change the pattern to triangles, I get this.

The lower surface is just ugly. I don't know how to make it look like the upper triangular surface.

Also, is there some other way to make these triangular glass curtain for the entire boundary? (other than using mass)

I don't understand what you are doing with the divided surface. Are you intending to use a Pattern-Based Curtain Panels?

Roof/Sloped Glazing by [Mass] Face would be another approach.  Or Curtain System.

Yes, I am going to use the pattern-based curtain panels. If I click on Wall by Face and set the type to Curtain Wall, Revit gives me some error.

Curtain systems will give me a rectangular pattern only. Can I set the pattern? I'll check out the Roof by Face method.

What tile pattern grid are you using? 

[kichappa]

Triangular (flat) pattern.

Well then, you can forget the other approaches.  Pattern-Based Curtain Panel is it.  But I can see where you will have issues, especially at those smaller surfaces.  You can change the UV spacing, but then the grids/patterns won't align with adjacent surface using a different UV spacing.  It's a design challenge for sure.

Okay. The problem I face now is in this lower triangular surface. In the upper one, the grid is independent of the boundary of the triangle. The grid is orthogonal. In the lower triangular surface, the grid is not orthogonal. Revit sets the top vertex as the origin and the two sides as the axes. I don't want those lines to coincide at the top vertex, rather, it should be independent like the upper triangle. How can I make that happen?
