trying to automate a boring task I have found what I believe is a bug in rhino.
The following script starts Grasshopper, loads a script and bakes an object. That all works per se. Object is baked and I can interact with it inside rhino. Commenting out the layout part of the script shows this.
The second part of the script adds a new layout and adds a detail to the layout. Executed by itself - skipping the GH part of the script - it works fine - layout is created, detail added.
Executing them after each other however (as in the script below) crashes Rhino on the line where it should add the detail. I tried switching away from the Layout back to a viewport but that did not help…
import Rhino
import rhinoscriptsyntax as rs
import scriptcontext as sc
# GRASSHOPPER PART
objPlugin = rs.GetPlugInObject("Grasshopper")
if objPlugin is None:
print("Error")
if objPlugin is not None:
#objPlugin.LoadEditor()
objPlugin.ShowEditor()
doc = objPlugin.OpenDocument("E:\\test.ghx")
if doc is False:
print("Error loading doc")
objPlugin.RunSolver(True)
objs = []
objs = objPlugin.BakeDataInObject("e9eb1dcf-92f6-4d4d-84ae-96222d60f56b")
# LAYOUT PART
a4_height = 297
a4_width = 210
lay = rs.AddLayout("Teste",(a4_height,a4_width))
if not lay:
print("Error in creating layout")
# Tried switching away from the layout in order to prevent crash, failed.
rs.CurrentView("Top")
# Crashes on next line
sideview = rs.AddDetail(lay,(0,0),(a4_height,a4_width),"Side View",3)
Does anyone have an idea what could provoke this? I have included an .GHX file that creates 10 cones called test.ghx, put it somewhere and change the path in the python script to reproduce. I think the GUID for the component to be baked should remain the same.
Rhino Version is 7 SR23 . It crashes without a “Report crash window”.
Any hints as to what I may do to resolve this issue (updating some obscure object table before adding detail or what not…) would be greatly appreciated!
Thank you very much and best regards

layout_id should be valid for all I know as all the checks below have not given any reason to suspect otherwise.
lay = rs.AddLayout("TestLayout",(a4w,a4h))
if not lay:
print("Error in creating layout")
ret = rs.IsLayout(lay)
if ret == True:
print("Is a layout")
sideview = rs.AddDetail(lay,(0,0),(a4w/2,a4h),"Side View",3)
frontview = rs.AddDetail(lay,(a4w/2,0),(a4w,a4h),"Front view",1)
So IsLayout returns True and then in the AddDetail the :
layout = scriptcontext.doc.Views.Find(layout_id)
Line causes the crash…
I have tried saving the file after the GH bake, opening a new one and then loading the saved file… does not work either. BUT… if i open a new rhino instance, load the saved file and execute the layout part it works… I’m really “at the end of my latin” here

Sadly it does not offer me that option, it just dies all silently and doesn’t even offer file recovery or anything else… it is just gone :).
Super interested to hear what you think about it

sure, here is a dumbed down script and i reattached the GHX file as well below I will outline the exact steps.
import Rhino
import rhinoscriptsyntax as rs
import scriptcontext as sc
# GRASSHOPPER PART
objPlugin = rs.GetPlugInObject("Grasshopper")
if objPlugin is None:
print("Error")
if objPlugin is not None:
#objPlugin.LoadEditor()
objPlugin.ShowEditor()
doc = objPlugin.OpenDocument("E:\\test.ghx")
if doc is False:
print("Error loading doc")
objPlugin.RunSolver(True)
objs = []
objs = objPlugin.BakeDataInObject("a54c048f-08a2-4799-a03b-c22eb64f36eb")
rs.Command("_-SaveAs "+chr(34)+"E:\\BakedObjs.3dm"+chr(34)+" _Enter",False)
rs.Command("_-New "+chr(34)+"Small Objects - Millimeters.3dm"+chr(34)+" _Enter",False)
rs.Command("_-Open "+chr(34)+"E:\\BakedObjs.3dm"+chr(34)+" _Enter",False)
# LAYOUT PART
a4_height = 297
a4_width = 210
lay = rs.AddLayout("Teste",(a4_height,a4_width))
if not lay:
print("Error in creating layout")
# Tried switching away from the layout in order to prevent crash, failed.
rs.CurrentView("Top")
# Crashes on next line
ret = rs.IsLayout(lay)
if ret == True:
print("Is a layout shouldnt crash :(")
sideview = rs.AddDetail(lay,(0,0),(a4_height,a4_width),"Side View",3)
Open a fresh Rhino
Load the Python Script Editor
Paste the script (save it for convenvience)
Set a breakpoint on the sideview = AddDetail line (optional - crashes in debug and not debug mode)
Execute the python script
(GH Loads, GH opens the test file, bakes objects, saves file etc.)
Continue at the breakpoint / or direct crash (if not debug mode)
→ The bakedObjects.3dm file contains the cones
→ Loading that file in a fresh Rhino and only running (comment out all the grasshopper stuff in the beginning and start with loading the file BakedObjs.3dm) the Layout part works → Layout is created no crash…
Hope that helps to reproduce it… if not let me know because it is really driving me crazy (all the tests I could do point to a non understandable issue for me).
