Any fast way to get all node coordinates?

lance.xi — Mon, 14 Jan 2019 09:00:11 GMT

I want to output all the nodes coordinates with NodeID.

The code I used is some one posted in the forum as following:

Dim StudyDoc, Node, Label, Coord
Set StudyDoc = Synergy.StudyDoc()
Set Node = StudyDoc.GetFirstNode()
While Not Node Is Nothing
    Label = StudyDoc.GetEntityID(Node)
    Set Coord = StudyDoc.GetNodeCoord(Node)
    DataFile.Write Label & Chr(9) & Coord.X & Chr(9) & Coord.Y & Chr(9) & Coord.Z & vbCrLf
    Set Node = StudyDoc.GetNextNode(Node)
Wend

The problem is that, when the model is complicated, it requires several hours to output.

Any other solution is faster?

Thanks!

Hello Lance,

the fastest way is to export the mesh into a text file format such as the Patran format or the UDM format. This writes all the mesh information into a text which you can then quickly read back using standard vbs commands to get the coordinates.

In fact, this is how many of the scripts I have written read and process the mesh information. Some of these scripts are already included as part of the Moldflow Insight installation (Look in: C:\Program Files\Autodesk\Moldflow Synergy 2019\data\commands). For example, look at the ExportGasCoreSTL.vbs file and find the ReadData function in the MeshClass class. Notice also that ReadData is called in the Class_Initialize function immediate after the line: "Synergy.Project.ExportModel UdmName" which is the command to have a script write the mesh data into a text file having the name of path which is stored in the variabel UdmName.
