BUG: Print Vector PDF Make strange dots at a certain scale

[Pipouille]

Hi,

I’m having a problem with PDF printing in vector output. Strange dots appear if I print the drawing at a scale of 1:10 or 1:25, from Wireframe and Technical Display modes. The dots don’t seem to appear at a scale of 1:5.

Wireframe 1:5

Wireframe 1:25

Technical 1:5

Technical 1:25

The drawings are made up of hatches and solid curves, some of which come from make2D.

Hi Pipouille -

@Pipouille

Strange dots appear if I print the drawing

Thanks → RH-84872 Print: Curves Print As Hatch Dots

Until this is fixed, you could use the SelShortCrv command to select and hide short curves. The length you need will depend on the scale of the detail.

Hi Wim,

As always, thanks for the summary and the clear follow-up.
Hope this problem isn’t too complex.

@wim

Until this is fixed, you could use the SelShortCrv command to select and hide short curves.

It can help, but not in all cases. As always with selection tools, blocks are not considered.

Best,
Pipouille

+1 the only workarround for now is to make2d
(top make2d bottom pen-displaymode)

thank you for the quick fix - at least at my end it works again!!

I printed with pen (white background) interestingely when I reimport the drawing back into rhino (which works miles better than make2d) and I zoom in there are those weird circles, that I cant find when I zoom into the pdf…

[…] and I zoom in there are those weird circles […]

I take it that you import PDF file with the “Import fill as” option set to Boundary curves?

[Sebastian_Wimmer]

thats correct - thank you very much! @wim

BUT: the circles just transform to dots when I use hatches

You are simply confirming the YT report…
I guess I don’t understand your feedback in this thread.

Sorry @wim I did not want to spread confusion - the printing issue was „fixed“ in the latest service release candidate yesterday - at least so much that you cant see the dots anymore when printing, I just wanted to add that when you import those pdf back into rhino de dots reappear (altough very very small)

Hi,

Thank you for the quick fix! But indeed it’s true that the problem doesn’t seem to have been completely solved.

If I take the same model as the one posted previously. I still have a few spots with dots appearing.

This creates gaps in some cases. And reimportation is therefore strange.
Here, it’s as if a line had been converted into a dot, leaving a space.

Hi sebowim and Pipouille -

@Pipouille

But indeed it’s true that the problem doesn’t seem to have been completely solved.

I see that, when importing the PDF back into Rhino, the hatches are still visible.

When looking at the PDF file, however, I’m not noticing any issues with the file that was provided.

→ I’m not seeing anything wrong here, and note that this is zoomed in 3200%!

Is this somehow still impacting your workflow?
