AddDetail script crashing Rhino

I can’t figure out why my script is crashing rhino. I can successfully complete the layout but not the detail.
The instant before rhino crashes a white rectangle appears on top of all four rhino viewports. Its definitely something that I am doing wrong. Not a rhino problem. (852 Bytes)

Hi @Ryan14,

Do you crash if you run the script in Rhino and not Grasshopper?

Here is the message I got.

Looks like there is a similar post to mine, without an answer.

Hi @Ryan14,

Here is a working sample. Perhaps you can adapt it to your requirements.

import Rhino
import scriptcontext

def AddLayout():
    scriptcontext.doc.PageUnitSystem = Rhino.UnitSystem.Millimeters
    page_views = scriptcontext.doc.Views.GetPageViews()
    page_number = 1
    if page_views: page_number = len(page_views) + 1
    pageview = scriptcontext.doc.Views.AddPageView("A0_{0}".format(page_number), 1189, 841)
    if pageview:
        top_left = Rhino.Geometry.Point2d(20,821)
        bottom_right = Rhino.Geometry.Point2d(1169, 20)
        detail = pageview.AddDetailView("ModelView", top_left, bottom_right, Rhino.Display.DefinedViewportProjection.Top)
        if detail:
            detail.DetailGeometry.IsProjectionLocked = True
            detail.DetailGeometry.SetScale(1, scriptcontext.doc.ModelUnitSystem, 10, scriptcontext.doc.PageUnitSystem)
            # Commit changes tells the document to replace the document's detail object
            # with the modified one that we just adjusted
        scriptcontext.doc.Views.ActiveView = pageview

if __name__=="__main__":

Good morning @dale

I will see what I can do with that. Thanks for your help!

I still can’t figure out where I am going wrong.
I copied your code while inputting the gh variables in place of the things that I wanted to change to no avail. I also change the document settings from mills to inches.
Here’s the result.

Still no thoughts on this?

Hi @Ryan14,

Can you post a .gh file that isn’t working?

Good Morning @dale
Here is the Gh File I cannot get to work.

Thank you for your patients with me. It is much appreciated.

Hi @Ryan14,

Does this work any better? (5.1 KB)

Just tried it. Instant crash. :sob:

Something interesting. If you watch the last second of the capture the It shows the default 4 view (Unintentionally) and there is a little grey viewport tab right behind the (Top) Viewport Tab.

Also, Just tried with Details set to 0. It successfully created a layout. Just with no Details.

Hi @Ryan14,

Can you run Rhino’s SystemInfo command and post the results?

Sure Thing!

Thanks @Ryan14,

GH isn’t all that happy about layouts being created from a solution. I’ve created an issue so we can investigate further.

You are amazing. Thank you for your time and for looking into this for me. Let me know if you ever find an answer.

-Ryan Grossmann

I know I am tacking onto an older post, still this year though.
I am running into this same exact issue. I can create the layouts in gh no problem, as soon as I try to use the AddDetail function Rhino crashes.

any headway on this in Rhino 7?

What does this comment mean?
Giulio Piacentino commented 24 Aug 2023 05:53
@Dale Fugier this is the old GhPython. I’ve fixed this, but I’m not sure about the new Python plans.

After creating the layouts in gh, I can select things in rhino and on the gh canvas, which is different from a comment in the issue.

Oh! in the issue it references 7.34 as the release target. I’m on 7.33
