I'm building a surface from multiple parallel straight linestrings. There are only a few defined points along each line, so the surface is drawing the triangles much larger than I would like. I would normally use the Corridor tool for something like this, but it won't work in this specific situation.

Is there a way to automatically divide a linestring at regular intervals?

Below is a snippet of what I'm working with. You can see in the center that the triangles extend the entire length of that section because the vertices are at either end.
