1. Click the button.

   The Capacity Calculator dialog appears:

   
   The dialog has multiple fields.
   1. For Social Distancing, you can enter the social distance value and press the Calculate button to estimate socially-distanced maximum occupancies.
   2. If you just know the Occupancy Rating and Capacity Factor, you can enter these values and calculate a Maximum Occupancy.
2. To calculate capacity for social distancing, enter the social distancing desired. This may be in metres or feet and inches, depending on the active unit setting.
   1. Press the Calculate button.

      i. This button is not enabled until a social distance has been entered.

   2. Estimates are shown in the Estimate 1 and Estimate 2 fields.

      i. To pick an estimate, press the Use Estimate 1 button or the Use Estimate 2 button. The selected value is entered into the Capacity field, and the Density field is updated based on object area and capacity.

      ii. To not use any estimate, click Cancel.

3. To calculate based on Occupancy Rating and Capacity Factor, enter values in those fields.
   1. The Maximum Occupancy is calculated based on OR x CF% = Maximum Occupancy.
   2. To use this value as the object’s capacity, click on Use OR x CF%. The selected value is entered into the Capacity field, and the Density field is updated based on object area and capacity.

Where a Delay Point or Waiting Zone capacity has been estimated, you can see the Capacity Calculator workings:

4. Right-click inside the object. A submenu "Capacity Calculator detail…" appears. Inside are options to show Estimate 1 (the square tessellation) and show Estimate 2 (the hexagonal tessellation)
   
   Note: The submenu does not appear when multiple objects overlap at the right-click location.
5. Click either option.
   1. Show Estimate 1 example. Note the square-grid arrangement of occupancy circles:
      
   2. Show Estimate 2 example. Note the hex-grid arrangement of occupancy circles:
      
   In both cases, Blue circles are counted in the estimates, red circles are excluded.

   1. The filled dot at the centre of each circle shows how close an entity would be an obstacle.
   2. Where an entity would be "too close" to an obstacle, the circle is excluded.
   3. The dot the largest entity size in the Simulator's system database, approximately 0.215m in radius.
6. To hide the estimate display, right-click inside the object again, and select Hide occupancy estimate for….
