Otherwise...
- if the template goes outside the image, there is a crash.
- I would have expected the pattern to be cropped along the lines of template?

I guess you mean the opposite (pathes that go outside template and are clipped on template boundaries)

No, I meant that the template can become bigger now than the image. In the last version this guided to a crash. But you are partly right: the other function is also implemented very rudimentary. There are still some issues, so I did not mention it as new feature. E.g. when a pattern point is exactly at a template point, or when a path-edge is going completely through the pattern, or … some special cases. Most of the time the result will only contain a few wrong colored triangles, but sometimes it also contains wrong triangles.

With this feature, it's now almost easy to create a 3D pattern, by creating two opposite checkerboard templates, create both triangulations and merge them, then cleanup (some triangles next to seams don't receive the right color) and make the projection. Two little things that would help a lot for that:
- when loading a new template, keep scale and position of previous one.
- Offer the possibility to name the output file to avoid unwanted overwrite.

In a future version, it should be possible to define ‘hard’ edges in the template. These will split the result into smaller areas. I think the creation of 3d patterns will be a little bit more comfortable then. But to name the output file would be a good improvement in any case.

Took me a while to find how: just key in ldraw color code in the color swatch boxes!

Sorry, bad description from my side.
