Overview
MAPP 3D presents users with an intuitive interface to create 3D models of venues, add loudspeakers and microphones, and optimize a system design using Meyer Sound Labs products. This page provides detailed information about the MAPP 3D interface and functions.
Operating Systems
MAPP 3D runs on the current versions of MacOS and Windows operating systems. Though it may operate on earlier operating system versions, proper operation has not been tested.
Video Monitor Display
MAPP 3D supports 1280×768 up to HD and Retina resolution displays. Higher resolutions may scale incorrectly or cause application instability. Please update graphics drivers to the latest version, which may enable 4k resolution.

Select Model View, Object Settings, Processor Settings, or Measurement View.
View Preset Drop-Down
Select view (camera) position from the default or custom views (created by clicking CREATE NEW in Viewport tab).
Main Window Tabs
At the top of the Main Window, there is a row of tabs used to switch between Model View, Object Settings, Processor Settings, and Measurement View 
.
NOTE: Tabs can be un-docked from the application window by double-clicking the tab. To re-dock the tab, double-click the top bar of the un-docked tab.

Available Tools In Model Tab
Primitives
These icons represent the primitive shapes that can be added to the model and modified 
. Primitives are used to represent the geometry of the venue or are added to CAD drawings where pressure plots are desired. Primitive types include 3D shapes, 2D shapes, and a Free Draw option. The Free Draw tool is used to create polygons by entering coordinates or clicking in the Model View for each vertex.
Available Primitives
Modifiers
Primitives can be manipulated in various ways by using modifiers . Extrude and Trim modifiers apply to only 2D Primitives. Offset modifies both 2D and 3D Primitives. Union, Intersect, and Subtract apply only to 3D Primitives. Objects must be on an unlocked layer to be modified.
Modifiers – 2D and 3D
Properties
When a Primitive is selected, its properties will be displayed in the Primitives tab 
. Different properties will be displayed depending on the geometry that is selected, but generally include position, orientation, and size. Objects must be on an unlocked layer to be modified.
Object Properties
Layers
All layers in the project are listed under this tab . Layers embedded in an imported DXF or SKP are also listed. Layers can be toggled between, locked/unlocked, made visible/hidden and renamed. Use the ADD and DELETE buttons to modify layers. It can be helpful to hide certain layers to work within a model. Use the Layer Management window to change layer colors, merge layers, and make bulk changes.
