Chapter 5. - Creating a Fire Protection Diagram
Use the Zoom Window command to zoom in around the
Double door.
This is also called “zooming in”, and is very helpful as it allows you to adjust the
view of the diagram on the screen so you can see exactly what you want to see.
Just place two diagonal points to define a window around the area you want to
view.
The Break Icon
Click on the Break (BR) icon in the Edit/Modify bin on the lefthand toolbox.
Click on the line near point A in Figure 5.10.
Autosnap to the hinge of the door symbol near Point B.
Autosnap to the hinge of the door symbol near Point C.
An opening will automatically be made in the line.
Select the Zoom All command,
It is not really necessary to snap to the endpoints of the door, but it does create an
opening that is more accurately sized. Now you can perform the same procedure
to break a hole in the vertical wall for the other door in Figure 5.11.
More Doors
In this section, we will add a Fire Door symbol and break an opening on an interior
wall. Then we will create an opening on the other interior wall.
Refer to Figure 5.11 for the following steps:
