Assign a symbol to a graphics in a view using Avenue

Summary

When you assign a symbol to a graphic, it is important you select the appropriate symbol type for the graphic type. If you select the wrong symbol type, you may get error messages.

This script below demonstrates how to check the graphic type before assigning a symbol.

Procedure

1. Open a New Script window.
2. Copy and paste this code.
   
   

   Code:
   '-- Get the GraphicList from the active view document
   theView = av.GetActiveDoc
   theGList = theView.GetGraphics
   
   '-- Create a BasicMarker symbol type
   aBasicMarker = BasicMarker.Make
   aBasicMarker.SetColor(Color.GetRed)
   
   '-- Create a TextSymbol symbol type
   aTextSymbol = TextSymbol.Make
   aTextSymbol.SetSize(24)
   
   '-- Cycle through the GraphicList
   '-- If it is a GraphicShape of type point, set symbol to aBasicMarker
   '-- If it is a GraphicText, set symbol to aTextSymbol
   
   for each g in theGList
   If (g.is(GraphicShape)) Then
     If (g.GetShape.Is(Point)) Then
       g.SetSymbol(aBasicMarker)
     End
   ElseIf (g.Is(GraphicText)) then
      g.SetSymbol(aTextSymbol)
   End
   End
   
   theView.Invalidate  

   
   
3. Compile the script and run it.
