Hi – I am having a really weird error when I enable & then disable the display conduit within a function, & then run more code, for some reason the len() function does not work. I am trying to get the length of a list, & found that list.Count works in this case. However, it is really weird that when…

Oh, also, I just tested the list.Count with the display conduit code commented out, & receive an error ‘list’ object has no attribute ‘count’ strange.

ACTUALLY – we just discovered that if you are importing Rhino to a python script you can call a list.Count, BUT if you do not import Rhino, a list has no attribute Count. Does Rhino somehow extend pythons list class to have the attribute Count??

I don’t think anyone is going to be very helpful without looking at some sample code…

here is the function where the conduit is called: def buildRules(shapeList,topos,sShapesIn ): addShape = False shapeRuleAddData = rs.ListBox(shapeList, "Select Shape to Add Rule", "NT_vTools v1") if shapeRuleAddData is None: return None shapeRuleAddDataTok = shapeRuleAddD…

vTools_latticeSetup_7.py (8.5 KB) here is the .py file – if you uncomment line 174 & run, you will get the error I am mentioning… Maybe the first question I have, though, is why when you import Rhino, you the Count attribute for lists work, but w/o importing rhino, if you try list.Count, it doesn’…

Well, I’m not smart enough to run your script. Perhaps a data file and some instructions might help. But on line 185, I do see this: len = bBox.Diagonal.Z len is a Python function, and you are reusing the symbol as a variable. Not sure this is allowed.

Yeah, it’s just setup to store brep objects in rhino’s document data. That does solve the issue, but it doesn’t answer my question of why a list, when you import Rhino, has Count as an attribute, but if you don’t import rhino, there is no Count attribute. In python, I know there isn’t meant to be Co…
