But as you can see the problem is, that when doing that, CoronaWire is changing the line weight when approaching a vertex. This effect intensifies when the line weight gets stronger. No matter if world unit or pixel size is checked.
The first attached image is with all lines, second one is only isolines.
Is this a known issue? I’d really like to see streamlined lines across multiple vertices
thanks for reporting this! I can confirm that the issue is there and when you make the lines so thick it’s quite apparent. We will fix this in daily build somewhere after 1.3.
