MEASURING A VENUE

You are required to enter the venue’s dimensions into the 
M3D Placement Calculator.

If scaled sectional drawings of the venue are available, you 
can use the dimensions from these drawings to determine 
the M3D array setup.

If scaled sectional drawings of the venue are not available, 
you can measure the venue by using a laser range finder, 
or alternatively, a long measuring tape.

Another less accurate option is to measure the venue by 
pacing it off, using a pedometer similar to item 3 in Figure 
5, and using this measurement to make an educated 
estimate.

Figure 5 shows some tools that can aid in the process of 
aligning an array and focusing it to the requirements of a 
specific venue:

1.  Binoculars

2.  Laser measuring tool

3.  Pedometer

4.  Laser inclinometer

5.  Self-leveling, four-way laser
