About Design Objects
Creo Flexible Modeling allows you to edit sheet metal Design Objects. Design objects, as opposed to features, are modified on top of the current model state, preserving design intent. Design objects are based on sheet metal features and are created when you do one of the following:
Create sheet metal features in a Sheetmetal part from Creo Parametric release 4.0 and above.
Create a Recognition feature for sheet metal features that were created in a Sheetmetal part in releases prior to Creo Parametric 4.0.
Create a Sheet Metal Recognition feature in a non-native part.
Sheet Metal design objects are visible in the Design Objects Tree when you enter Creo Flexible Modeling. When you are editing design objects, you can use the Sheet Metal Items smart filter to aid selection. Design objects are available as search filters in the Geometry Search Tool. When you move the mouse over a design object that can be edited in a tool, its attributes display.
