After you click Display settings from the left pane of the Steel tab, the parameter options are as shown.
Under Display, specify which elements to display in the drawing area:
If Redraw acceleration is selected, then when an entire structure is displayed, a part of structure elements will not be shown (for example, connection details or connection symbols) due to an acceleration of model display on the screen. It is recommended to activate this option in the case of large structures.
Under Clipping presets, specify values for distances between clipping planes and UCS.
For Marking of machinings, select a color of machinings made in elements of a structure model.
