Hidden Mode
To redraw in hidden mode:
1. Press 2D HIDDEN LINE.
2. Pick HIDD DRAW.
3. Identify the appropriate viewport to use the z-value information when redrawing.
Creo Elements/Direct Drafting displays the drawing partially covered (depending on the z-values associated with the assembly drawing).
Note that Creo Elements/Direct Drafting displays "-H-" in the upper left hand corner to confirm hidden mode.
