It seems that the API we used in ePD2005 for modifying symbols is not available in EE2007. I have two scripts, one cleans up symbols that we have created using SymXpert, the other creates a POP (part on part) symbol from a regular symbol. A POP symbol looks like a regular symbol, the pin information is replaced with graphics and text. These scripts no longer work in EE2007. The new symbol editor is Tcl based but I haven't seen a way to have the editor call a Tcl script from within the tool to modify a symbol.
What does Mentor propose that we use to modify DxDesigner symbols programmatically?
