Determining the Scale Factor for a 3D model

Before importing a 3D object, you must consider the scale factor to use. You can calculate the appropriate scale factor for a 3D model by comparing the measuring units used by Harmony to the ones used by your 3D modeling software.

This can be done by importing a cube that is 1 unit in size, cubed, in your 3D modeling software, into Harmony. Then, you can adjust this cube's scale factor until it matches a unit in Harmony.

To be able to match the size of the cube against a unit in Harmony, you can enable the 12 Fields grid. Units in a 12 Fields grid are shorter vertically than they are horizontally, to match the 4:3 aspect ration of legacy standard displays, but you can use their horizontal size as a reference for square units in Harmony.
