Selecting structural levels

You can select structural levels by clicking the relevant check box. The program takes into account the drawing file status when the corresponding structural level is selected.

• Clicking a check box selects the relevant structural level and all subordinate levels.
• Clicking a check box while selecting and holding the Ctrl key selects this structural level only; subordinate levels are not included.
• If subordinate structural levels are selected, a fill is applied to the check box of the superordinate structural level.
