Issues with Technical DM PDF printing

Hi All,

There are some curves freshly pulled onto the surfaces.
In Technical DM those curves are partially recognized as hidden and as a result printed dashed.
My workflow is to have hidden lines off so I have partially missing words in resulting PDF.
Also PrintDisplay shows text in full. I don’t trust it anymore.
For instance, Shaded DM makes full text visible in printed PDF.
I understand, it’s a different display pipeline.

I would highly appreciate two things: curves on surfaces printed correctly and proper work of PrintDisplay.

Hello @Gijs and @wim

Could you please take a look? Is it something on my side or you can reproduce it?

Hi Screamer -
I’ve taken several looks since you posted that…
This is dependent on the display mesh, but in my (quick) tests so far, I can only make it worse… Normally, we bias curves toward the camera to make sure that they are over curved surfaces like in your sample. Biasing has its downsides as well, but technical display modes seem to be handing this somewhat differently, though, and so-called Fake2d is something different still.

[FWIW, the layout in technical display mode looks a lot better on my Mac than it did on Windows…]

I’m afraid that PrintDisplay is a legacy workflow. I wouldn’t dream of using it to “predict” vector PDF output. I’m funneling scarce resources to fixing the way forward, not the way back…

Hello @wim

I saw this fixed in the latest RC. Thank you.
But I see another issue with the same file.
You may try to reproduce it.

My Technical DM is modified to show no edges (creases, silhouettes). Just curves.
But output PDF still has edges shown.
Is it possible to get rid of edges?

Hi Screamer -

No, that doesn’t appear to be possible.
I’ve put this on the list as RH-87047 Print: Vector Print Prints Turned Off Edges

Thank you, @wim

Unfortunately, I have another Technical DM issue with curves on surfaces. Now it’s read thru.
Could you please try to reproduce?
