Manage worksessions through script

Scripting
1

I would like to be able to modify worksession files in an automated way. I would like to specify which model is the active one and I would like to automatically add or remove models to a worksession. I would also like to be able to save a worksession to a specified location.

If a .rws file would be human readable, all of the above would be very straightforward, however, it is not. I can’t seem to find any references in the Rhino Common reference, nor in any Rhino Script reference.

Can anyone help me out?

RhinoScript contains the following worksession related methods:

WorkSessionModelAliases
WorkSessionFileName
WorkSessionModelCount
WorkSessionModelNames

Check the RhinoScript help file (Help -> Plug-ins -> RhinoScript) for details.

These methods, along with the fact that the Worksession command is scriptable, should allow you to do what you’ve described.

For example, the following script allows you to set the currently active worksession model.

Sub TestWorksessionCurrentModel
	
  Dim arrModels, strModel, strCommand
	
  arrModels = Rhino.WorkSessionModelAliases
  If IsNull(arrModels) Then Exit Sub
	
  strModel = Rhino.ListBox(arrModels, "Select model to set current:", "Worksession")
  If IsNull(strModel) Then Exit Sub
	
  strCommand = "_-Worksession _Current " & Chr(34) & strModel & Chr(34) & " _Enter"
  Call Rhino.Command(strCommand, True)

End Sub

Does this help?
