Is it possible to fill a shape with a pattern, if the shape is one that has been imported from a Sketchup model?
There’s a couple of options. You can trace over the shape with the drawing tools in LayOut so that you get a shape to fill with the pattern or you could explode the viewport so the SketchUp edges become lines in LO. For that, you might want to make sure they shape you intend to fill is in its own scene.
