Printing shaded views - surface edges color incorrect

Just to be clear: although I have narrowed the problem down to printing selected objects in Shaded view, it still needs resolving.


Understood. Thanks Max. This is still on our radar…

Hi Max.

I tested this again in 5C146w (the latest RhinoWIP) and I am still having problems reproducing the behavior you are seeing. I’m drafting up a TODO item: MR-2651 …sorry to be dense about this, but what am I doing wrong? Can you please take a look at the steps I’ve drafted in MR-2651 and see what I’m missing?


Hi Dan,
I stumbled upon this once again using the latest WIP, so I searched for this thread to see how this bug was recorded and I noticed I never replied to your latest request. Sorry about that.
The step that you missed between #10 and #11 is to go to the “visibility” options in the printing dialog, and check the box “only selected objects”.


@maxz, @dan - here, with ‘Selected objects only’ in Visibility, I get a blank white page in the pdf preview, without that setting I get object color edges, even though the viewport shows black edges - the original complaint, I think.


Not the original complaint Pascal, see my post about halfway. The complaint was and is colored edges with “Only selected objects”, black edges without ( i.e. printing all visible objects).
I am puzzled why you are getting a blank page though, assuming that you did select some objects to begin with.


Thanks for getting back to this and for the clarifications. I’ve amended MR-2651 with the steps as I understand them. Please double-check those as I’ve changed them to integrate your feedback.

Unfortunately, I’m still getting the same expected result from where I sit. Can you please walk-through the steps in that item to see where I’m going wrong? I feel like I’m missing something obvious here :confused:


Hi Dan.
Th steps in MR-2651 are now correctly describing my actions. However, I am getting a different result, I’ll let the pictures speak for themselves:

However, I noticed something that may hold a clue: as soon as select an object and open the print dialog, the black edges change to colored ones, even before I check the “only selected objects” -box!

I tried changing the select color, without result.

Some of my settings:

Hope this helps,

Edit: Note that all my examples above are using “Display color” as the output color. “Print color” does not show the black edges at all, regardless of the visibility setting. “Black and White” shows black edges all the time.

It looks like the examples you showed in your MR-2651 write up are using black as the object color ( I cannot see your output color setting), which will always have black edges since that is the native edge color, so you would not be able to see the difference.

This bit of clue I’m not sure what to do with, but…good news…

I am able to reproduce what I think you are seeing (finally!) I was doing something quite wrong, which you noticed:

Yes indeed, in the MR-2651’s writeup step 4, I wrote Black! (I’ve since changed it to Blue). That was a mistake on my part…now that I change that critical detail, I think I am better understanding the report. Can you please look over MR-2651 once again to make sure? (I’ve edited it quite a bit).

Thanks again!

Hi Dan,
I am glad that this bug continues to have your attention, but I don’t quite understand why you have gone a different route and color the edges blue instead of the object cyan as I did, but in the end it does not make a difference I guess.
My comments on MR-2651:
step 8: There is no reference to the visibility settings when the picture was taken. Assuming that “only selected objects” is not checked at that point, it already displays my “clue”, in the preview the edges appear black instead of blue.
This makes step 9 sort of obsolete. It may be better to move step 6 (selection of the object) to a new position between #8 and #9, and edit step 9 to show that toggling the “only selected objects” setting makes no difference.

As you can see, I am getting more and more convinced that selection of objects is triggering this phenomenon, and not the visibility settings.
I made this screenshot of two objects, the larger cube is selected, the smaller is not. “only selected objects” is off.


Sorry, I’m probably overly fixated on the title of this topic, or the “surface edges color incorrect.”

How about this, since I’m completely confused, can you please write out the steps you are taking again to reproduce what you are seeing? I’m unable to get the preview to show the wrong color. I just want to make sure we’re taking the same steps and seeing the same thing. Feel free to just copy/paste from MR-2651 if you like. I’m not even sure what I should be looking for anymore.

OK, here goes:

To Reproduce:

  1. Launch Rhino for Mac; start a new modeling window.
  2. Set layer color “Default” to cyan.
  3. Create 2 Boxes.
  4. In Preferences > Display Modes, create a custom display mode (based on the default Shaded mode) called “Shaded copy”.
  5. In “Shaded copy” settings, in the Objects tab, under the Surfaces section, set Edge color usage: to Use single color for all edges and set the Edge color to Black. Close the Preferences window.
  6. Set the Perspective viewport to Shaded copy…at this point you should have a cyan box with black edges like this:
  7. Select one of the boxes you created in step 3 above.
  8. Run the Print command.
  9. In the Print dialog, change the Linetypes and Line widths settings to match those showed in this image:
  10. In the Print dialog, check Visibility to ensure all objects are printed:
  11. Print to PDF using the PDF > Save as PDF option in the lower-left corner of the Print dialog.
    EdgeColorTest.pdf (217.1 KB)

Expected Result: The surface edges print in black.
Actual Result: The surface edges of the selected object print in cyan.

Max (sorry, I did not manage to capture volatile dropdowns from my screen as you did to show the view settings)

Edited: I removed the “lighter shade of cyan” bit, in fact the edges are not distinguishable except for the darker shaded surfaces

Thank you @maxz! Finally, I’m seeing what you’re seeing. Much appreciated. I will amend MR-2651 with your instructions. Thank you for the hand-holding here.


My pleasure. Somehow you managed to print the surfaces darker than I did, the cyan edges do stand out much more.


@Marlin: I see this is slated for 6.x, is there any chance that it can still be resolved in version 5?
I tried to create a workaround with a customised “Pen” mode which shows the object color, which works sort of but the edges are grey i.s.o. black. And I was not able to show individual objects in layout details using SetObjectDisplayMode, see SetObjectDisplayMode - missing display modes


Edit:, OK, so the missing display modes has been resolved, but the main problem still exists, and the part-workaround I found does not work in Layouts.

Edit2: I found a better workaround, in the Preferences > Display Modes > General > Surface edge settings > Edge thickness / Color reduction, set to 1 and 100% (for black edges).

I have the same problem. I have the ‘show edges’ setting set to solid color (black). In my layout it appears black, when I print it appears the same color as the object. I have tried selecting it and not selecting it, neither works. I just started running Rhino 6, not sure if there is something new I need to do, I never had this issue in Rhino 5. Although when I open this back up in Rhino 5 my background is showing up grey instead of white on certain detail views but not others.

Anyone figure this out in Rhino 6??

I have the same issue as Maxz. Set me surface edges to black. They appear black in model space and in layout, when I print, the edges show up the same color as the surfaces.

Anybody figure this out yet?

I tried that, I still dont get the black edges on my parts. Driving me nuts

RH-38049 is fixed in the latest Service Release Candidate

In your print settings there is a section that says ‘output color’. There are 3 options, ‘print color’ ‘display color’ ‘black and white’

‘Print color’ will be selected by default, you want to use ‘display color’, this will translate the color in your layout into your print.

OAN: the issue you are having where black is showing up grey, instead of using true black, use a very dark grey. True black shows up as grey in rhino.

Hope this helps, the edge color was driving me insane for the past hour.
