Hello all, I’m new in Dynamo and I already searched a lot on internet to find an answer to my question but unsuccessfully… I’m working on a Python Script and I want to use the “Curves” methods (Curve.StartPoint, Curve.Length, etc) that we can find in dynamo nodes. I added all the possible and inim…

You cant replicate in a python script. You’ll need to loop through your list of curves item by item and perform your action: startpoints = [] for crv in curves: startpoints.Add(crv.StartPoint) OUT = startpoints

Hello @Mostafa_El_Ayoubi , thank you for your answer ! But it’s already what I’m doing and in fact it works for a lot of methods (like Line.ByStartPointEndPoint) but it doesn’t work for curves methods like Curve.Length, Curve.StartPoint, Curve.EndPoint, … :confused:

It is possible that there are other functions called Length , StartPoint etc. in the other libraries you imported, resulting in the interpreter being incapable of knowing which function you’re calling (I may have not phrased that correctly, but I think it’s the general idea)

Ok maybe… But even if I specify Curve.Length(mycurve) ? The error I get when I try to compile is “TypeError: getset_descriptor is not callable”

@Mostafa_El_Ayoubi is right, so in these cases you have to specify the reference assembly, namespace, class then the method. A good example is Plane.ByOriginNormal. To use in Python you have to declare the following otherwise it throws an exception: pln = Autodesk.DesignScript.Geometry.Plane.ByOrig…

Ok thank you ! I tried this but now I get an other error : NameError: name ‘Autodesk’ is not defined

If you’re importing ProtoGeometry then it should work. Post your code

Here is the beginning of my code, I take as input argument the curves representing the bases of my walls and I try to get the StartPoints in my Python Script [image]

@Thomas_Mahon or @Mostafa_El_Ayoubi any ideas ? :slight_smile:

Ok thanks, it works ! Thank you for your time !

Hi @ansobr ,
you just need :
import clr
clr.AddReference(‘ProtoGeometry’)
from Autodesk.DesignScript.Geometry import *
