Line weights MASSIVE v8 and useable V5

Hi,
0.5 line weight was able to make line stand out a bit from the rest. (in V5) when print preview was ON.
now in V8 its MASSIVE.
what setting makes my line weights behave as before , else I am facing a massive blow to my visuals. everything a mess.

and with PP off too thin to see easily.

Hi Steve, did you try the recommendations i provided the other day?

A file is always helpful in these cases. Thanks

Hi, not yet, as V5 has shaded mode curve width pixels 1. , so if all my v5 projects are set in pixels, should not they continue to be so in V8 ?
I need to be sure the appearance is as per V5, when I open them to V8, and V5 uses pixels.

so whats happened to make pixels appear so different ?

Steve

I believe its due to scaling being added. I prefer the units so that you can control the width in relation to Rhino objects if need be.

I am a little puzzled, exactly where and what do I get hold of and clone, then in future I dont use shaded I use shaded custim, or what ?
or does the altered line weights sit within a normal shaded mode ?

and what do I make it so as it matches V5 ?

it means my V5 will open to shaded and need altering on each and every project ?

please elaborate more.
I ddnt expect having to alter shaded mode etc.

Lineweights are pretty buggered in V8. I think this needs to be brought out into the open more. It’s really really bad and I don’t want to even guess how many hours I’ve got into it.

There’s certain things you can avoid in order to make the lines appear not so bad. It depends on which display mode you’re basing your visuals off of. Japhy mentioned curve scaling which is one possible cause:

You can control lineweight both with layers and linetypes. Things get a little complicated as you have to pick a means of controlling your line thickness both as displayed and printed. Print Display is also broken (completely broken in some display modes, might work in others). I could type you a novel but your best chance of getting concise help will be by both sharing your file and exporting your display mode.

If you post small example files with an isolated condition in R5 and R8 I will be happy to take a look.

You have 3 overall ways to control Object Line weight in Rhino 8:

  1. Object Property Settings
  • Layer (Section Style, Print Width, Linetype)
  • Section Style (By Layer, By Parent, By Clipping Plane, Custom)
  • Linetype Override
  • Print Width Override
  1. View Settings
  • Display Modes
  • Display Modes have various Object Types with different options (Scale, Width Usage, Edge Settings)
  • Print Preview
  1. Project Settings
  • Linetypes
  • Width Units (Pixels, Doc Units, MM, …)
  • Print and Display - User Model Units
  • Print Settings (Apply Display Modes, Raster/Vector), Units, Default Width)

Great summary!

It has to be mentioned that a lot of this stuff is broken right now. Check the post history. I feel like McNeel is ignoring a lot of the issues going on. Print Display is broken in certain display modes if not completely broken. It might work in model space it usually is not working in layouts. The lineweight/type issues I’ve mostly narrowed it down to a scaling issue. It seems like someone doesn’t understand how things should scale. Curves scale properly but objects (edges, Silhouettes, intersections, etc… ) and section outlines don’t. Display modes based on Shaded seem more reliable. Also if you control line weight through the Display Mode and not using Linetypes that seems more reliable but still doesn’t cure every issue.

Currently it’s a mess!

As far as I understood from the beginning of V8 development is that PrintDisplay is considered “Deprecated” and that line weights should be controlled by assigning linetypes that have a thickness defined to objects or layers - and are thus seen in realtime without PrintDisplay being active. There are still the issues of layout space scaling - whether you use it or not and how you do.

I have definitely noticed some bugs with linetype display scaling in model space even with correctly defined linetypes applied.

I’m more than happy to adjust the PrintDisplay command to work how users want it to work. I could use some very specific input on exactly what you want to see.
