Script to Export Selected Objects into DXF while the annotation inside the selection become the filename

Scripting
1

I am writing a Rhino script to export the selected Objects into a DXF file. As each object in the 3dm has a name nearby. So during the selection, I am selecting all the curves + the name.

For example:

I have started a script like this, but the problem is I do not want to loop through all the selected objects to find the text. Is there a fast way to get the Text string out from the selection?

Sub SmartSelectionExport()
Dim arrObjects
Dim strObject
Dim strFileName
Dim strPathName
Dim strAnnotation

arrObjects = Rhino.GetObjects("Select objects for export as .DXF", 4 + 512, True, True, True)

If IsArray(arrObjects) Then

	For Each strObject In arrObjects
		If Rhino.IsText(strObject) Then
			strFileName = Rhino.TextObjectText(strObject) + ".dxf"
		End If
	Next

	If IsNull(strFileName) Then
		Exit Sub
	End If

	strPathName = Rhino.DocumentPath() + "\" + strFileName
	
	' runs the export using the file name/path and your settings
	Call Rhino.Command("-_Export " & chr(34) & strPathName & chr(34) & " Scheme Default Enter", True)
End If

End Sub

Also, I do not want to have to press Enter to finish the selection. Is there a way to disable that?

This is probably not the best way to do it but it works. Using the code attached, you need to pick the text wanted for the name as the first pick of the selection:

arrObjects = Rhino.GetObjects("Select objects for export as .DXF", 4 + 512, True, True, True)

If IsArray(arrObjects) Then
strObject = arrObjects(0)

If Rhino.IsText(strObject) Then
  strFileName = Rhino.TextObjectText(strObject) + ".dxf"

Else
Rhino.Print "First Picked item is not text"
Exit Sub
End If
End If

If not IsNull(strFileName)Then
strPathName = Rhino.DocumentPath() + “” + strFileName

' runs the export using the file name/path and your settings
Call Rhino.Command("-_Export " & chr(34) & strPathName & chr(34) & " Scheme Default Enter", True)

End If

Rhino.UnSelectAllObjects

Haven’t figured out how to grey out the code yet…

If the name chosen for the dxf already exists in the folder, then that existing file will be over-written

Take care using the ‘Default’ export scheme as it will explode all your polylines, your black lines will remain black at the recipient end, tricky if they have a black backfround, your layer names are full path which can be really messy for the recipient and ‘chord height’ is un-checked, so there is a good chance your polylines will lose accuracy which could go un-noticed until assembly time. It would be safer to experiment and create a custom scheme to suit your needs.
