rs.AddLeader problem

[Sandra3 (Sandra)]

Hi
I couldn’t find out how to create a leader from script. Currently I’m using Rhino 7.
got the same problem with

rs.AddText(rs.AddText(“Hello Rhino!”, (0,0,0)))

I’ve tried all the codes at this post.

Any suggestions?

It works if launched by th Rhino Python Editor

Thank you

Hi guys. If you want to fiddle with the Rhino document from GHPython, you must explicitly set the script context to target the Rhino document. Here’s one approach: import Rhino as rc import scriptcontext as sc import rhinoscriptsyntax as rs # Set context to Rhino document and disable redraw sc.doc = rc.RhinoDoc.ActiveDoc rs.EnableRedraw(False) # Fiddle with the Rhino document # Set context back to Grasshopper rs.EnableRedraw(True) sc.doc = ghdoc

Thank you @AndersDeleuran

• how to recognize command in RhinoScriptSyntax that need scriptcontext?, and
• the leader and the text aren’t dynamic. Are there other command to do that?

@Sandra3

… how to recognize command in RhinoScriptSyntax that need scriptcontext?

You can usually tell by the output window error message (refer to your screenshots). Other times it depends on what you’re trying to do. For instance, rs.AddPoint will simply return a point (i.e. that exists only in memory), but if you change the script context to target the Rhino document first it will “bake” the point (i.e. add it to the Rhino document).

Afraid I don’t know. But, you can inspect the rs.AddText source code and see what it’s actually doing.
