How to create a cross from 1 part?
Okay, probably my subject-title isn't very clear but I don't know how to put it (English is not my native language).
But I hope I can make clear with a sample what I mean.
I want to create like something on the left. I now did this with several lines. But when I enlarge the thickness of the lines I see that the 'corners' show 'gaps'. How can I create like something on the left from 1 piece, so if I enlarge the thickness it won't show those 'gaps'.
