V8 Polysurface lineweights: wireframe vs shaded views

Is there a way of getting polysurface edges to print at the assigned print width in anything other than wireframe view?

Hi Andrew -

In Rhino 8, I would recommend to use the new linetype properties on objects/layers and configure your display modes as required. You can then use this in the print options:

Hi Wim,

In the attached I have set the middle plate at the top a linetype width thicker than the other plates. I have set “use linetype widths” in the print dialog.
My Arctic mode modified to show edges responds to the setting, but Technical and monochrome do not.

It is crucial in documentation that objects appear the same across different display modes. Is this possible?
And is there a way to control the linetype used for hidden lines in Technical and Monochrome display modes?

Thanks,
Andrew

Hi Andrew -

The linewidth system for technical display modes is completely different than that for the other display modes, also in Rhino 7. It’s planned that the two systems merge into a single display pipeline at some point in the future.

We are introducing vector print from technical display modes in Rhino 8. The hidden lines will follow the hidden linetype pattern, and will, as such, be configurable. Visible lines will likely use the “continuous” linetype in the first implementations in the release version of Rhino 8. It’s somewhat unclear to me if, or when and to what degree, the viewport in the technical display mode will reflect what the vector output will be. All of this is actively being worked on and, thus, too early to tell for sure…

Hi Wim,

Until the pipelines are merged, is there a way to control the display of line widths of objects using different display modes on the same Layout?

It’s really bugging me (and my boss!) that I can’t have objects look the same on the same sheet.

Hi Andrew -

Not if you are mixing display pipelines.

Hi Wim,

I made a discovery today. Drawings print at different lineweights depending on the monitor Rhino is working on. WHen working directly off my Dell laptop monitor (3840x2400), line widths displayed close to as expected. The difference in lineweight between technical and non-technical was noticeable but acceptable:

Then I plugged the laptop into the work monitors (fairly average low-res monitors) and the lineweights were out of control:

I was losing my mind trying to get the drawings to print properly till I realised it was the monitors. Once I unplugged and printed natively off the laptop, the drawings printed as expected.

Are you able to advise what display modes are affected by screen resolution? I did not realise this was a thing until now…
It’s certainly not expected or desirable. If one sets their print width to a certain size, one would expect the drawing to print the same, regardless of monitor resolution.

And are you able to advise how I can increase the line weights of my technical display modes? Is it the pixel scale option in the print dialog?

Sorry for all the questions, but drafting and documentation - being able to communicate the design to others effectively - is a crucial and fundamental function of software like Rhino. Being able to have absolute control over how a drawing looks is critical.

Thanks,
Andrew

@Andrew can you send me that last file?
What display modes are you using?
