    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?
