Little update from me.
The mentioning of logos made me take a look at the logos I created and I saw they are made with fp_poly.
So I made it again using polygons and a width of 0.00001. Then I put a SMD pad on top of it
I also used a polygon to create the solder mask as it will not get affected by the mask offset which you get when using a pad.
I made a picture to demonstrate both ways I did. (Taken in pcbnew.)
I must say I'm quite happy with the polygon solution and prefer it over the stacked trapezoids.
As it's only for a connector on the board edge, I will only connect traces to the inwards of the board, so that won't pose a problem.
Also it looks much cleaner this way
Again, thanks for all the help.
