Insert General Sloped Photometric Calculation Area
|Up Previous Next|
The Insert General Sloped Photometric Calculation Area command is used to insert a sloped area on the drawing, such as stairs, where general footcandle levels are to be calculated.
To insert a sloped general area boundary on the drawing, go to
DM Electrical->Point-by-Point Photometrics->Insert General Sloped Photometric Calculation Area
Insert Sloped Photometric Calculation Area Boundary Dialog Box
See thesection for information about the values in this dialog box.
Inserting the Sloped Calculation Area on the Drawing
To insert the calculation area on the drawing, press OK. The settings you specified in the dialog box will be used for the area that you insert.
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.
When you define the area, you will draw two crossing lines in the middle of the rectangle. The first line will start at the top edge of the rectangle and end at the bottom edge of the rectangle. The second line will be perpendicular to the first and go from one side of the rectangle to the other.
You will first be prompted to specify a point on the edge of the rectangle that is at the top elevation.
Specify top of calculation area:
Then you are prompted to specify a point on the edge of the rectangle that is at the bottom elevation.
Specify bottom of calculation area:
Then you are prompted to specify a point on one of the sides of the rectangle that slopes.
Specify point on edge of calculation area:
Then you are prompted to specify a point on the other side of the rectangle that slopes.
Specify point on opposite edge of calculation area:
A rectangle will be inserted on the drawing enclosing the specified points. The outline of the rectangle will be thicker at the higher elevation to help you visualize how it slopes.
You will be prompted to specify the location of the photometric schedule on the drawing for the new calculation area or indicate another calculation area that the new area is to be grouped with.
Specify insertion point for photometric 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 you 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, none will be used for the group.
Not Insert the Calculation Schedule and Not Group the Calculation Area: Press ENTER to not insert a calculation schedule and not group the calculation area with another group. No calculation schedule will be inserted and the calculation area will be in its own separate group.
