The VTYP (view type) command controls the hidden-line representation of pictures. Six possible VTYP settings are provided. These give progressively greater graphical accuracy at the expense of increasing processing requirements. The facility allows you to produce preliminary and intermediate drawings (where graphical accuracy can be of secondary importance) quickly, leaving only finished drawings to incur the greatest processing overhead. The default VTYP setting is WIRELINE, which gives a conventional wireline picture.
Wireline Hidden Line Removed representation produces a View where hidden lines are removed from individual significant elements (EQUI or SUBS) but not from items hidden behind them.
Local Hidden Line representation gives a picture where hidden lines are removed from individual significant elements (EQUI or SUBS), but not from items hidden behind them.
Global Hidden Line representation gives a picture where all hidden lines are removed.
