@ugur_yavan_61 Quickstart Guide for Dynamo in RSA 2023 - Robot Structural Analysis - Dynamo (dynamobim.com)
Did u read this ??
i don’t have the RSA documentation but in revit api startpoint and end point work in this manner with this method of “GetEndPoint” , Here if need startpoint passing indes as 0 and 1 for the endpoint so u could see if there’s something similar to this exist in RSA Api.
Thanks,
BM
