When is a curve not a curve (Solved)

Recommended Posts

In this example I have created a letter T as a polygon. I also added a letter T and converted to curves. Why the different behaviour to the geometry - subtract operation?

I have seen this happen in other software when the two objects shapes/curves are in the same direction or in different directions when combined. Perhaps try reversing the direction of one of the two then do it again?

I was sceptical of your answer but mirroring the letter T made a difference. Well done.

Now having read this article

https://2dgameartguru.com/vector-orientation-understanding-a-frequent-problem/

I have a different perspective of this issue, previously I had literally flipped the letter T, now I show the solution with simply reversing the NODE ORDER using the Reverse option in the Node tool. Certainly now a handy tip for me.
