Insert Egress Sloped Photometric Calculation Area

The Insert Egress Sloped Photometric Calculation Area command is used to insert a sloped area on the drawing, such as stairs, where egress illuminance levels are to be calculated.

To insert a sloped egress area boundary on the drawing, go to

Ribbon: DM Electrical->Point-by-Point Photometrics-> Insert Egress Sloped Photometric Calculation Area

Pulldown Menu: DM Electrical->Point-by-Point Photometrics->Insert Egress Sloped Photometric Calculation Area

Insert Sloped Photometric Calculation Area Boundary Dialog Box

See the Common Photometric Boundary Information section for information about the values in this dialog box.

Inserting the Sloped Egress Calculation Area on the Drawing

To insert the calculation area on the drawing, press the OK button. The settings you specified in the dialog box will be used for the area.

You will be prompted to draw the calculation area on the drawing. The area will be inserted as a rectangle. The top elevation will be on one side of the rectangle and the bottom elevation will be on the opposite side of the rectangle. The two connecting sides will slope from the top side to the bottom side.

You will draw two lines to define the area. The first line should start at the top elevation of the slope and end at the bottom elevation of the slope. The top and bottom edges of the boundary will be drawn perpendicular to this line. The sides of the boundary will be drawn parallel to this line.

The second line you draw should start at one side of the slope and end at the opposite side. The locations of the sides of the rectangle will be determined by the start and end points of this line.

You will first be prompted to specify a point on the slope that is at the top elevation.

Specify top of calculation area:

You will then be prompted to specify a point on the slope that is at the bottom elevation.

Specify bottom of calculation area:

You will then be prompted to specify a point on one side of the slope.

Specify point on edge of calculation area:

You will then be prompted to specify a point on the opposite side of the slope.

Specify point on opposite edge of calculation area:

A rectangular boundary will be inserted on the drawing enclosing the specified points. The outline of the boundary will be thicker at the higher elevation to help you visualize how it slopes.

You will then be prompted to insert the calculation schedule, group the calculation area with another area, or press ENTER to finish the command.

Specify insertion point for calculation schedule or point inside boundary to group with:

Insert a Calculation Schedule: To insert a calculation schedule, select a point on the drawing that is not inside of another calculation area. A calculation schedule will be inserted at the point specified.

Group the Area with Another Group: To group the area with another group, select a point on the drawing that is inside of another calculation area. The two calculation areas will be grouped. If the selected calculation area already has a calculation schedule on the drawing, it will be used as the calculation schedule for the group. If it does not have a calculation schedule, no calculation schedule will be used for the group.

Finish the Command: Press ENTER to finish the command without inserting a calculation schedule or grouping the calculation area with another group. No calculation schedule will be inserted and the calculation area will be in its own separate group.
