Currently in Creo 2.0 you can define many sketches that can be used to create an extruded feature. The only way to change which sketch is used for the extrude is a manual redefine or reroute. I would like to be able to use a parameter to control which sketch is used for the extrude feature. This should work similar to parameter used for patterns by table. This would give me the ability to write relations to control the parameter for different situations and reduce user input. This will greatly reduce time and improve accuracy on designs. Do not limit this to just extruded features, apply to ALL features that can use a predefined sketch.
Please vote for this if you think it is a good idea to improve Creo.
