So i'm currently working on a steel diagrid frame, to support a 8 storey building. One of the facades is sloping inward making the area smaller as the elevation goes up. this result in two triangluar sides with incomplete surface grids. My pattern is made from "Metric Curtain Panel Pattern Based" with a triangular(Flat) base grid.
Now, i want the surface pattern to fill the whole grid, so I can join the triangular sides with the sloping backside.
Below: the first picture displays the building, and the secound one off walls with the border tile set to "empty" the third with "parcial"
in other words, I want the pattern to be "cut" outside the grid surface. I have tested with different parameters and pattern familys, but always with the same result. How do i accomplish this?
