Rather than clicking, you can also hit Enter when you have positioned your cursor, or you can enter the exact coordinates using the number keys on your keyboard.

The Gate object is displayed in the workspace. At each end of the gate you will see that there are automatically created trapezoids. These represent the space where Entities queue to use the gate when it the gate is occupied. You cannot modify these areas.

Depending on where your cursor is placed, the Gate object will display an arrow indicating whether the gate is an In, Out, or Switch gate. The illustration above indicates an Out gate (because the cursor is hovering over the trapezoid at the 'paid' side of the gate).

If you shift the cursor towards the centre of the Gate, you will see a double arrow, indicating the Switch state.

And if you move the cursor to the trapezoid at the 'unpaid' side of the gate, you will see a green arrow, indicating the In state.

The Edit Gate dialog box is displayed. Its active contents will differ according to which state of Gate you have chosen. Here a 'Switch' gate's parameters are illustrated.

• Orientation matches the orientation specified when the Gate was drawn but can be changed here, if an alternative orientation is wanted. Changing orientation automatically enables and disables the appropriate 'IN' and 'OUT' options and tabs.
• Choose the Gate Control Profile which manages the timing and operation of the gate from the Control profile list.
• Use Step into gate options to select whether queuing entities will step into the gate immediately behind the current occupier or wait for the occupying entity to leave the Gate.
• By default, entities queue at a Gate informally, but politely (as dictated by the Gate's focal segment directional arrows). To apply formal queuing instead, tick the Formal Queue box.
