Rhino 8 Section Style Issue

I am having a persistent issue with creating section drawings with clipping planes in layout. Whether I use “section style” or set the display mode for all cuts to have a solid hatch and heavy lineweight, they all come out the same. They default to hairline linewidth and the fill matches the applied material.

I have had this issue for a while now and see it has come up on the forums before, but I can’t find a satisfactory answer. Please advise

Hi @real_cool_cowboy ,

I see two approaches to solving this. Change your default line width to .25mm (or larger if preferred) or change the dpi to less than 600 at this paper size. 300 for instance with hairline width will have more of a contrasting thickness between the section silhouette and the hatch.

I hope that helps.

I appreciate the response. It is worth noting that this problem arose recently, and the section style was working (somewhat) well prior to that (~August). I opened an older file that I had been using while section style was working and re-PDF’d old drawings that had proper lineweights before, and now they are displaying incorrectly with lineweights and hatches all messed up.

I say this only to indicate that no changes have been made to my rhino settings, print settings or display modes since then, and this might be a bug or problem with a recent update.

Hi Real -

So you always print to the same paper size, no matter which file?
At any rate, if you can provide a file that used to (somewhat) work and the print settings, I can try that in previous versions of Rhino 8.
-wim

can i send it to you directly?




clipping plane settings dont work either
spot the difference

and with sections styles



Hi Cowboy,

Try duplicating the Continuous linetype (default is set to pixel width), change the new linetype to your file units and set to the layer you are using for your objects.

japhy you are a king
this worked
thank you so much

Also try the Rhino 8 sr15 release candidate now to print with the scaled boundary width.
You can turn this on in Rhino with the Options → Updates Statistics and pick update frequency as Release candidate. And then Check for updates.

The Print Width that is assigned to layer with the custom section style, will now be scaled by this factor.

Give it a try with the Release candidate if printing this boundary is a goal.
Sincerely,
Mary Ann Fugier
