Sorry about the spelling, and fat fingering.
Look at the pdf, with 2 viewports of the same drawing. One is set to 24 scale and the smaller one is set to 48, but as you can see the hatching scale is the same size on both drawings. But when I zoom in and out, I want my hatch to zoom in and out at the same rate.
I don't know maybe it's only this hatch, wh-diagcross. but this is a problem I have had many times with a lot of other hatch patterns.
Look at the second hatch , now it did what I want , it reduced with the objects.
That's what I am trying to figure out, I want the hatch to zoom with the drawing, it seems to have a mind of it's own sometimes.
Probably just me.
