I’m trying to produce a terrain using the sandbox tools, but the TIN ends up jumping over most of the edges in this area. It seems like the From Contours tool actually ignores edges, and instead just triangulates the end points?
Here are the contours I’m trying to create a mesh from:
Here are the results of running From Contours
And here’s that same view, but with Endpoints shown, and back edges:
This was imported from CAD, and you can see it’s a little funny how the contours are created.
But the TIN basically ignores edges and just “connects the dots” wherever points occur. I’ve run the Simplify Contours plugin with no improvement. Does anyone know a solution for this? I was hoping to find a plugin that would “divide” a selection of edges, inserting end points at a set interval. I think that would produce a better result, but I haven’t been able to find anything. Any other ideas? I’ve attached the contours lines if you’d like to mess around with it. MSketcher_Contours.skp (1.0 MB)
