Linetype scaling in model space

  1. Can linetypes have their own scale in model space like dimensions can?

I want both the lines in model space and in layout space to show up as the same dash-dot scale in layout (printed) space, so I am forced to use SetLinetypeScale to 1, and Print Display is set to show linetypes. However, if I go to my model, which has larger units (feet vs inches), the line in model space is showing up as true printed scale (dash-dot dimensions in fractions of an inch). As the dash-dots are so tiny compared to the model, the lines look continuous.

Can there be some Options scaling factor such as dimensions have, for reference only?

  1. Could specific objects be able to have their own linetype scale? For example, I have three basic sizes of centerlines (small dash-dot, medium dash-dot, large dash-dot). But if it so happens that I have a short line, I may need/ want to customize the dash-dot pattern for that particular line, simply so the dashes show up legibly when printed. Currently, I would have to make a unique linetype just for that specific line. If it happens again with another line at a different length, I’m again forced to make a custom linetype. This simply bloats up the linetype list.


Linetypes work a little different in Rhino that Autocad. In the print dialog box if you have this checked then linetypes will print at the true scale no matter what is linetype scale is set to in the model.

No objects currently can’t have their own linetype scale factor. Although multiple people have asked for it, so I think it may be on the wish list.

Yep, using that Match Pattern Definition already, and it makes everything look fine in Layouts. However, what I really want is shown below; and option where the lines in model space can be scaled for viewing reference.

A wish for McNeel’s list.


Yes I agree. It is already there under linetypes, but I would be nice to have it on the front pages where all the others scales are controlled.


Done! That’s exactly what I wanted. Just did not know where it was. Yes, it might be more logical under the same page as the others though.


Got that- added as



Whoops, I spoke too soon. That’s NOT exactly it. That linetype scalar in the Options/ Annotation/ Linetypes dialog box works for model space, but it then changes the scale of similar dashed lines in Layout. If you have the linetype scale set to 1, with PrintDisplay/ LayoutLinetypes=ON, then all the dashed lines look the same in Layout. That’s OK for Layouts, but doesn’t work when you go back to model space. In model space, you want the linetype scalar larger, like 50 or 100 if you’re working in large units like feet, not 1. So what I really am asking for is a true model space linetype scalar, like annotations have. The text, dimensions, and leaders are scaled up as a reference in model space, but then true scaled in Layouts. That’s what linetypes should have.


Thank you,

Huh seem work for me here. So if I have a file were the plan is 1/8"=1’-0" (scale factor 1/96) and I set the linetype scale to 96. They look the same in model space as in Detail in layout space. Check out this example of some details drawn at 1-1/2" = 1’-0" (scale factor 1/8). They look both the same in model space or layout space.


With that said if you actually draw a line in layout space it would look correct, or if you have two or more Details (viewports) at different scale they won’t look correct either. Although if you use “Match Pattern Definition” in the print options they will print correctly.

Hi Guys,

We’re a year older since Matt started this topic and still linetypes are a real headbreaker.
There’s no way to keep them consistent.

1/ There should be a clearer way of defining linetypes. I’d like to regard them as some kind of helpers, when reading a drawing. So everywhere you encounter a linetype, it should be of a consistent size. Off course, we don’t have the luxury to always keep their visual size the same on our screens, when we’re zooming into some geometry in model-space. But what we cán control is the rendering in paper space. That’s why I prefer to think of linetypes as defined in relation to the (printed) paper. And refer to this scale as scale=1.

e.g. Centerline: 10, 3, 2, 3 (my units are mm’s)
Now, drawing a centerline in modelspace, it should only ‘show itself’ as 50 times larger. Like Matt’s earlier suggestion: Model Space Scaling= 50. Setting the scale for viewing in model space would not change the linetype’s settings, not really.

2/ When coming to the layout, regardless of its scale (1/20, 1/50, 1/100), a linetype should always look the same on paper. And I’d like to have them on screen too, not only after printing.

There are some things making it confusing:
*As it is now, in layout, if we draw a centerline on the paper, Rhino draws this line with a linetype scaled up to the set model-scale. This is counter intuïtive.

  • Also on a layout page, model-drawn lines show up differently than do the paper-drawn lines.
  • We can’t presume all ‘detail views’ to be at the same scale. It would be nice if a drawing at scale 1/100 and its detailed drawings at scale 1/10 would have linetypes at a consistent scale.

Best regards,


Hi @BartGo (and @pascal)

This is the best description of my battles with Linetype scaling. It’s exactly right, so thank you for being so clear and thorough about it.

I will also update this and say we are now 2 years since BartoGo wrote this (3 yrs since the original post) and - please do tell me if I’m wrong - this still seems to be an issue. I’m using Beta v6 and I had a hell of a time trying to work out the line scales. Same problem - I use multiple viewport scales in a document, and linetype modeling scale seems to have to be set to around 48 or 50 in order to have the lines read properly while drawing (I draw/model in 2D/3D most of the time in room-size contexts)

Has there been any headway on this front that maybr I just don’t understand in v6?

Thanks as always

Use Options command to define your custom linetypes.

Hello everybody,

I am new to Rhino and need to ask a slightly different question on the same topic.
First of all I am using the Mac version.
Let’s say that in model space I draw a large rectangle, line weight 3mm.
In layout I need to have a detail of that complete rectangle on a small scale (1:25 or 1/4") and an other detail showing a corner of the same rectangle scale 1:1.
For the full size detail I need the line weight to be 3mm which works out fine but by having that the detail with the rectangle on a small scale can’t be read.

is there a way to basically fix the line weight to the model space so that will come out to scale in different details?

Hi Irene,

is there a way to basically fix the line weight to the model space so that will come out to scale in different details?

I believe it is this option in the Print dialog that you are looking for.
I made a simple model and it is attached.


You can preview this on the layput with the PrintDisplay command configured like this:
Print Display (Layout Viewports) ( State=On Color=Print LayoutLinetypes=On ):

Let us know if this works for you.

Hi Mary,
Thank you for the reply.
Unfortunately it’s not fixing the issue.
Maybe I phrased it in the wrong way. I’ve attached a print from a basic model, that should explain a bit better.
The line next to the man has thickness 1mm in the model.
The view on the right is 1:1 and it’s fine at 1mm thickness, I do want a nice thick line.
The view on the left is 1:25 and due to the line thickness, it’s not easy to read, it’s merging into itself. If it was to scale, a line 1mm thick full size should ideally be very thin when view at 1:25.
Does it make any sense?

So far I had solved the problem by keeping a thin line in the model space (0.18) and then, when doing full sizes, I would in the viewport trace over with a 1mm thick line. It allows me to get to the print I need, it’s just not very practical because if something changes I have to retrace over every time.

any idea? :slight_smile:

If you want to scale line width globaly per plot, you can do it in the print dialog:

The following is based on the Windows version, but I assume the Mac side has something similar. You can also adjust line weight per detail via layers. So in your 1:25 detail, double click into the detail to make it active. You can then modify all the object on a layer you are interested by using the per detail controls in the layer pallet. You can leave the line weight heavier in your 1:1 detail.

You can also adjust the print width by the object properties, but this will affect it in all details.


I don’t seem to be able to navigate linewidth management. I want Linetypes that print at the same size of dash and dot in all windows regardless of the window scale.

Choosing “Use Pattern Definition” in Print Settings doesn’t work as expected. if I rely on scaling dimensions in Options, Using Pattern Definition doesn’t respond to a large enough range of scaling to get them to a large enough scale, and if I edit the linetypes themselves to make them bigger, that setting results in different instances of the same linetype printed to different scales.

Of course choosing Match Viewport Display results in linetypes that are scaled with all the objects, varying from window to window.

I am either mismanaging this or something’s off in my project or settings somewhere.

Hi Djhg,
Can you tell us what Rhino version are you using?
The linetype scale, unit and pattern definitions are set per file in Document Settings. The linetype print style (Match Pattern Definition or March Viewport Display) is set at print time. Rhino does not have a linetype scale per object.

Please send us a sample file and images that will show us what you are seeing on the display. Indication what you feel is incorrect and what you expected to see. Also print to PDF and send that file along as well.

Thanks in advance.
We will be able to investigate the issue more thoroughly.

Thanks Mary, but that post was 26 days ago. I’ve somehow limped past it and have other issues to work through at the moment. This is the least of them, but maybe I can get back to it again before too long.

Hi @djhg,
When you are ready to revisit this, just post your files and @mention me.
You can also email with any urgent issues.

Also note that Rhino’s display of linetype scale is by and large completely unusable and unrepresentative or what you will get, especially when working with layouts. If you have your print settings set to Use pattern definition, when printed they should measure as they are in the pattern definition. The display will almost always be wrong, so don’t look for the print to match the display. Really the only way to get a feel of what linetype scale will look like is with check plots.
