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.
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…

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?
Unfortunately, I have another Technical DM issue with curves on surfaces. Now it’s read thru.
Could you please try to reproduce?
The file is attached. 1111.3dm (3.7 MB)
I’m seeing that in your file, but I can’t reproduce this from scratch.
I’m just getting a spinning wheel when I try to run your video so I don’t know if that gets into the details of how to reproduce this.
When I turn on the camera of your detail, it looks like this:
I’m seeing something else going on as well and will get that on the list ( RH-87161), but could you provide instructions on how to get a detail’s camera to behave like the one in your file?

Hello, @wim
Thank you for paying attantion to my problem.
This is weird. Works perfectly on my side. You may try different browser.
Yes, I have no issues with standard Right view of the Detail too. Text doesn’t go thru the surface.
But my detail has slightly different angle than Right view.
It’s perpendicular to the front face of the body, marked by red arrow below.
So, in order to replicate the issue, here is the instruction below (working on the same file, attached couple posts above):
0. Let’s delete any detail from the layout.
Create a detail. Activate it. I make it Shaded for better managing.
I make it Perspective first, for easy picking of surface I need.
Activate Auto Cplane. Ctrl+Shift+Click on the front face.
Keeping Ctrl+Shift pressed, start View rotation with RMB. Release keyboard buttons and then push it back while keeping RMB pressed. This should align view perpendicular to the CPlane (to the selected face in our case)
Change the display mode to Technical. Activate layout. Try to print. Here we are. Text is see thru now.
BTW, if you will try to print the Model space in Perspective view with Technical DM, you will be surprised. The text is see thru and all the curves are off place.
I don’t know what’s the issue with this particular file. But trying the same with brand new file and simple box with fillets on ribs doesn’t reproduce the issue. All the duplicated edges seemed to be in place.
I’ve just replicated the issue from scratch.
Made similar L-shaped polysurface, added fillets, duplicated edges (changed line type), added text curves (pulled to the back face), rotated all slightly. Then all the manipulations with Detail view from above. Same see thru result.
Thanks, it looks like this was introduced in 8.19 as a result of a different fix. → RH-87169 Print: Fake2D: Curves are Moved
Thanks, I’ve added such model to RH-87169
What I was trying to reproduce, however, was RH-87161 - namely that occluded surface edges are showing through in the technical display mode in model and layout space, not the curves showing through in print preview and print. I’m not seeing that when placing the camera with your instructions.

Could you please at least unroll this thing back till whole issue is fixed? At that time I had a workaround with drawings. Now I don’t have any.
How can I download previous Rhino RCs, btw?
I see this fixed (not by YouTrack, but by testing) on the latest build of V9. Thank you!
But it still persists on V8.
Does this mean it won’t be fixed for V8?
I’m not sure how you are testing this on in the WIP as the settings for display modes are completely messed up for the time being.
At any rate, as you noted, this is not reported as fixed in RH-87047 - which is set to Rhino 9. I can only assume that means that this is something that will only happen in Rhino 9, yes.
