rs.CurveDomain returns tuple instead of a list

[Grischa]

Hi Steve,

Isn't the rs.CurveDomain() supposed to return a list?

At the moment it is returning a tuple instead.

I'm asking because the rs.TrimCurve() example doesn't work with the tuples.

Python Code:

import rhinoscriptsyntax as rs
 
curve = rs.GetObject("Select a curve to trim", rs.filter.curve)
 
if rs.IsCurve(curve):
 
    domain = rs.CurveDomain(curve)
 
    domain[1] /= 2.0
 
    rs.TrimCurve( curve, domain )

As tuples are immutable it throws:

Message: 'tuple' object does not support item assignment

Traceback:
line 9, in <module>, "C:\Users\Win7Pisa\AppData\Local\Temp\TempScript.p y"


Thanks,
Grischa

It is supposed to be returning a list according to the Help... I'm not sure if I would be wanting to change the numbers in place anyway - I think that would be confusing if for some reason later you wanted the domain of the curve from the variable (domain) but you had modified it... As you're trimming the curve I guess it doesn't matter though...

I guess the workaround is to force domain to be a list and modify that.

domain = list(rs.CurveDomain(curve))

Hi guys,
I just changed the CurveDomain function to return a list instead of a tuple in order to match the documentation. This will be in the next V5 beta or you can get the modified script beforehand from github at
