First, access the vertex through GeoData, for example through its Id like:

geoData = ExtAPI.DataModel.Project.Model.Analyses[0].GeoData
vertex = geoData.GeoEntityById(27)

Then the coordinates can be accessed with:

vertex.X
vertex.Y
vertex.Z

The coordinates are in meters, so how can I obtain them in millimeters?

Hi - from geodata the units are as far as I can see always in meters (m). So easiest is just to multiply the above script by 1000, if one wants it in mm.

Dear Erik,Thank you!
May I ask one more question?
Can coordinates be obtained with reference to an arbitrary coordinate system?

vertex.X

I got the following error:
'NoneType' object has no attribute 'X'
What could be wrong, please?
