How To Measure Profile

UpdatedOctober 16, 2024

Profile

In the On-Axis application, term “profile” means a sectional view (or “cut view”) that is measured with one or more measurement points (“targets”) with a laser distance finder. The distance and angle are measured for each point and the profile of the audience area is calculated from this information.

Step 1 – Instrument Position

Mathematics is based on trigonometry and in order to calculate the geometry correctly, the position of the measuring instrument must always be set.

The height at which the measuring tool is held. Swipe to recall your stored measuring instrument.
Depth offset can be used to allow measurements behind (-) or in front (+) of the actual starting point. Sometimes the laser does not hit every place and you just need to step back for a better view.
When you´re not measuring from the floor, like on a stage, use height offset to adjust for height differences.

Step 2 – Measurement Table

Measure the profile in order from front to back.

There are two types of tables. Standard where all rows of the table are regular measurement points. And another type is table with offset where the first measuring point is an offset point. The offset is used in Arena and Circle models, where the offset tells the app the distance of the measuring instrument to the profile.

Standard Table (Basic)

Table With Offset (Arena & Circle)

When the first measurement point is Offset Target, the first measurement point is taken at the joint of the floor and the profile. The first plane is then used as a offset and it is not included in the drawing. The profile starts drawn from where the floor ends. 

Step 3 – Measurement Modifiers (optional)

Long press the tool symbol to access the measurement modifiers menu, where you can customize measurement points.

The Seat Height parameter enables measurements to be taken using the seats. Set the height of the seat and choose whether the measurement is taken on the floor or on the seat.
Manual Depth allows you to manually enter the depth of that measurement point. Manual input can be used, for example, in situations where the coordinates of the measuring point must be determined using an alternative method.
Manual Height allows you to manually enter the height of that measurement point.
Note

Manual input can also be used in situations where the profile needs to be drawn from a section image.

By default, the measurement points are linked to each other and a plane is always drawn between them. If this is not desired, you can deactivate the link feature between measurement points, leaving it undrawn.
