OS. Using functions that only return a single value

Type nodeCount = geometry.GetNodeCount and then press Return.

This uses the OpenSTAAD method GetNodeCount() to return the number of nodes in the active STAAD.Pro model into the specified variable.
Type beamCount = geometry.GetMemberCount and then press Return.

Similarly, this uses the OpenSTAAD method GetMemberCount() to return the number of members in the active STAAD.Pro model into the specified variable.

Tip: Reference the OpenSTAAD API Documentation for details on available methods and what values are accepted as input or returned from each.

Your program at this point should look like:

Python

from comtypes import automation
from comtypes import client
import ctypes
os = client.GetActiveObject("StaadPro.OpenSTAAD")
geometry = os.Geometry
geometry._FlagAsMethod("GetNodeCount")
geometry._FlagAsMethod("GetMemberCount")
nodeCount = geometry.GetNodeCount
beamCount = geometry.GetMemberCount
