I’m drafting a pretty normal architectural drawing set in Rhino 5 educational, using Layouts and then Print to make PDFs. Using both CutePDF and Adobe PDF writers, I am getting these fuzzy spiky edges around my solid hatches. It appears to be worse on spline/bezier curve outlined hatches, but still is bad on lines-and-arcs polyline border hatches, and even infects some line-only polyline border hatches.
If I zoom in on the PDF, the spikes are still there although they decrease in size, and I can tell from the refresh-draw render when panning on the PDF that the hatches are made up of thousands of very skinny mesh-like triangles…I have changed the lineweight on my HATCH layer to no avail, it’s currently at Default. Same appearance on different computers and devices when I send the PDF. How to give my hatches a haircut??
