Venue

Quickly Draw Venue

In some instances, users need to quickly and accurately build a model in MAPP 3D without importing CAD or SketchUp drawings. This page contains information about measuring venues and creating a MAPP 3D model based on measurements.

Tools Needed

  • A laser range-finder and an inclinometer are needed. Several models are available that include both fuctions. Some models have longer ranges, cameras, and other helpful features, especially for longer distances outdoors in daylight. The accuracy should be less than +/- .25 m and +/-0.2 degrees.
  • A standard camera tripod with a small, laser reflective target for the range-finder. A small white box is sufficient.

Templates

Create templates to decrease time spent on-site. It is helpful to add and label layers, processors, loudspeakers, and microphones. Also, add geometry representing a generic stage and generic seating areas representative of a venue type, e.g., arena, proscenium, shoe box, or fan-shaped.

Multi-Level Visual Aid

A Multi-Level Visual Aid (MLVA) is a tool used to convert measured coordinates, distances, and angles to Free Draw geometry. A Reference Point is chosen, distance and angle measurements are taken, and entered. MAPP 3D creates a Free Draw object based on the entered measurements.

Seating Sections Added with Multi-Level Visual Aids

Multi-Level Visual Aid Example – Add Rectangular (non-curved) Balcony

The stage is located in the model with 0, 0, 0 at the point where the face of the stage meets the floor, on the center line of the room.

The width at the front and rear of each seating area is recorded, 25 m and 28 m for this balcony.

Select the Reference Point Position (measurement position), in this example, 0, 0, 2.5 m is downstage center, 1.5 m above the 1.0 m tall stage, to have a better angle when measuring the balcony seating.

If not taking measurements facing directly downstage, enter the degrees of rotation in the Reference Point Azimuth, the Z-axis rotation.

Distance and angle measurements are taken from the Reference Point to the top of the backs of chairs in the first and last rows.

The geometry added represents the chair height. The prediction plane can be offset from the geometry, typically 0.3 m (1 ft) above the seats.

Select INSERT > MULTI-LEVEL VISUAL AID and enter the coordinates of the Reference Point Position, then the distance and angle measurements to the front seat and rear seat in the balcony, along with the widths:

Model View – Multilevel Visual Aid Added as Free Draw Geometry, Point 1 and Point 2

NOTE: The Reference Point Position (yellow sphere above) is the measurement location, in this instance: 0, 0, 2.5 m.

Click INSERT to preview the new geometry. Click OK to convert the Multi-Level Visual Aid to a Free Draw object with points that can be edited later if needed.

For contiguous seating areas that have different inclinations, add more points using the buttons, take additional measurements, and enter them in the MLVA dialog.

Venue Drawing Examples

Below are examples of different venue types. There are a variety of ways to quickly measure a venue and represent it in MAPP 3D. The steps below are intended as a guide and are expected to be modified for specific circumstances.

Arena Example – Symmetrical

Another way to use Multi-Level Visual Aids (MLVA) is to draw a single line representing the section view of a seating area, an Architectural Profile. The Extrude Linear or Angular modifier is then used to create the seating areas and architecture.

Record all measurements in digital or analog form to be copied/pasted or entered into MAPP 3D dialogs later.

Although there are many steps, they can be completed in about 10 minutes with proper preparation and when the steps become familiar.

Measure Arena Floor

There may be hockey dashers that define the floor, if not, use the first row of seating.

Step 1: Measure and record length (X) and width (Y) of the arena floor. Where they intersect will be 0, 0, 0 in MAPP 3D (O for origin). From the origin, right and up are positive x,y coordinates, left and down are negative x,y coordinates.

Measure Arena Floor, O = Origin, 0,0,0

Locate Reference Point Position

The Reference Point Position is the location from which the Architectural Profile will be measured.

Step 2: Move to the location where the curve of the corner seating becomes straight on both sides of the corner. Place the tripod here (R for Reference Point).

Place Tripod Where Corner Curve Stops on Both Sides of Corner

Step 3: Move to x = 0 m, measure distance to the tripod target and record the distance (A).

Measure Distance (A)

Step 4: Move to y = 0 m, measure distance to tripod target and record distance (B).

Measure Distance (B)

Step 5: Measure and record the height of the tripod mount to the floor, (Z).

Tripod with Target, Measure Height (Z)

Step 6: Mount the range-finder/inclinometer to the tripod at location, (R).

Measure Seating and Architecture

This example assumes that the Architectural Profile, the shape of the seating area, is symmetrical. Asymmetrical Architectural Profiles are discussed later in this page.

Step 8: Measure the Architectural Profile. Take measurements at the beginning and end of each seating section and architectural feature starting at the bottom and progressing to the top.
