Summary: How to export all objects by layer, with each layer exported to a new file.
The following RhinoScript demonstrates how to export all objects by layer, with each layer exported to a new file.
Option Explicit Sub ExportLayerObjects ' Declare local variables Dim strPath, strFile Dim arrLayers, strLayer Dim arrSelected ' Get the path to and name of the current document. ' Surround with double-quotes in case path includes spaces. strPath = Chr(34) & Rhino.DocumentPath & Rhino.DocumentName & Chr(34) ' Get names of all layers arrLayers = Rhino.LayerNames ' Disable redrawing Rhino.EnableRedraw False ' Process each layer For Each strLayer In arrLayers ' Unselect all Rhino.Command "_-SelNone", 0 ' Select all objects on layer. Surround layer name ' with double-quotes in case it includes spaces. Rhino.Command "_-SelLayer " & Chr(34) & strLayer & Chr(34), 0 ' Make sure some objects were selected arrSelected = Rhino.SelectedObjects If IsArray(arrSelected) Then ' Generate a modified path string ' that includes the layer name strFile = strPath strFile = Replace(strFile, ".3dm", "_" & strLayer & ".3dm") ' Export the selected objects Rhino.Command "_-Export " & strFile, 0 End If Next ' Unselect all Rhino.Command "_-SelNone", 0 ' Enable redrawing Rhino.EnableRedraw True End Sub
The script can be altered to export different filetypes: change “strFile = Replace(strFile, ”.3dm“, ”_“ & strLayer & ”.3dm“)” to “strFile = Replace(strFile, ”.3dm“, ”_“ & strLayer & ”.xxx“)” where xxx is the desired filetype extension. Do not forget to update the script name in the second line (e.g. “Sub ExportLayerObjectsIGES”).
