One of the options in the attached Python script is to output a column showing ‘Other Attributes’, which my script gets from Attribute User Text. This works great, unless the Value is a function, in which case it doesn’t work at all.
Here are steps to repeat the issue:
Make an sphere.
Select sphere and go to the Attribute User Text panel.
Click on Fx.
Pick something, like ModelUnits.
Run my script.
From the command line, select Columns.
Change OtherAttributes to Yes.
Click enter, and finish the script.
The output should go to the history window, but the ModelUnits will be incorrect.
In contrast, if you manually enter a value in AttributeUserText, it will show up on the BOM correctly.
To clarify:
When I use a script to get Attribute User Text, the value returned in the script is sometimes a formula, not the result of the formula. So, instead of getting ‘Inches’ for ModelUnits, the script returns ‘%<ModelUnits()>%’.
Here’s a Rhinoscript example: if I create a sphere, open Attribute User Text panel, and click on Fx and pick ModelUnits, then run the following, the output is ‘%<ModelUnits()>%’ instead of what I see in the Attribute User Text panel, which is ‘Inches’. Is there a way to return ‘Inches’ instead? ModelUnits isn’t the best example b/c I can get that other ways, but…I just want to be able to retrieve the values of UserText.
Dim strObject
strObject = Rhino.GetObject("Select object")
If VarType(strObject) = vbString Then
Rhino.Print Rhino.GetUserText(strObject, "ModelUnits")
End If
import Rhino
import System
def _IsFormula(str):
if str and str.startswith("%<") and str.endswith(">%"):
return True
return False
def TestPrintFormula():
filter = Rhino.DocObjects.ObjectType.Curve
rc, objref = Rhino.Input.RhinoGet.GetOneObject("Select curve", False, filter)
if rc != Rhino.Commands.Result.Success:
return
obj = objref.Object()
if not obj:
return
coll = obj.Attributes.GetUserStrings()
print("KEY, VALUE")
for i in range(coll.Count):
if obj:
key = coll.GetKey(i)
value = coll.Get(i)
if _IsFormula(value):
value = Rhino.RhinoApp.ParseTextField(value, obj, None)
if not value:
value = "####"
print("{0}, {1}".format(key, value))
if __name__ == "__main__":
TestPrintFormula()
apologize but i do not see this (and all other above examples) working here too. It seems the only thing your script prints is:
KEY, VALUE
After trying to debug this i’ve found that anything after calling the ParseTextField method seems to fail to print. Eg. if i run this code:
if _IsFormula(value):
print "IsFormula returned True"
value = Rhino.RhinoApp.ParseTextField(value, obj, None)
if not value: value = "####"
print "Hello ?"
print("{0}, {1}".format(key, value))
the script prints this:
KEY, VALUE
IsFormula returned True
I do get the same either using V7 or V8 most recent versions. Rhino running in english language on a Win10 running in german.
Here is a specific script (exactly what Pascal posted). Result is a ‘return’ on the command line (no text, just a blank line). It sounds like Pascal is getting the same result that I am. I’ll attach the Rhino file. I don’t think this is the same bug that Clement is seeing (if I put a print command after the ParseTextField line, it does print.) I’ve tried your exact script too, and the result on the command line is “Select curve” then “KEY, VALUE”, then “0”
import Rhino
def main():
filter = Rhino.DocObjects.ObjectType.Curve
rc, objref = Rhino.Input.RhinoGet.GetOneObject(“Select curve”, False, filter)
if rc == Rhino.Commands.Result.Success:
obj = objref.Object()
if obj:
formula = obj.Attributes.GetUserString(“CurveLength”)
print(formula)
value = Rhino.RhinoApp.ParseTextField(formula, obj, None)
print(“{0}”.format(value))
if( name == “main” ): #call function defined above
main()
