A new option is available in Draft to give assembly display configurations and PMI model views full control over what is displayed in drawing views. Now you can show surfaces, curves, centerlines, sketches, coordinate systems, and reference planes in a drawing view, in addition to the solid design bodies.
The new option—Include reference, sketch, and construction items—is available in the following locations:
On the General tab (Solid Edge Options dialog box), to define a document level preference.
On the Display tab (Drawing View Properties dialog box), to override the display of a selected drawing view.
You can use this option to reduce complexity in a drawing. For example, you can display tube, pipe, or frame centerlines without displaying the solid bodies of the tubes, pipes, or frames.
