Description

Description:
Draws an icon at the given position in the game world. This command has to be executed every frame. Use the Draw3D Mission Event Handler (which is executed every frame if the user can see the icon).
In order for the results of this command to be visible through a custom camera, enable HUD with cameraEffectEnableHUD.
showHUD false will hide the icon drawn by this command.
In order for arrows to appear, the icon texture should exist. The arrow size is proportionate to the icon size.

Examples

Example 1:
Icon and text:
addMissionEventHandler ["Draw3D", { drawIcon3D ["targetIcon.paa", [1,1,1,1], ASLToAGL getPosASLVisual cursorTarget, 1, 1, 45, "Target", 1, 0.05, "TahomaB"]; }];
Example 2:
Just text:
addMissionEventHandler ["Draw3D", { drawIcon3D ["", [1,0,0,1], ASLToAGL getPosASLVisual cursorTarget, 0, 0, 0, "Target", 1, 0.05, "PuristaMedium"]; }];
Example 3:
iconPos = player getPos [10, 0] vectorAdd [0,0,2]; addMissionEventHandler ["draw3D", { drawIcon3D [ "\a3\ui_f\data\IGUI\Cfg\Radar\radar_ca.paa", [0,0,1,1], iconPos, 5, 5, getDirVisual player, "COMPASS", 0, 0.3, "PuristaMedium", "center", true ]; }];
Example 4:
Since Arma 3 logo black.png2.04
pos = player getPos [10, 0] vectorAdd [0,0,2]; addMissionEventHandler ["draw3D", { _k = 10 / (player distance pos); drawIcon3D [ "\a3\ui_f\data\IGUI\Cfg\Radar\radar_ca.paa", [1,0,0,1], pos, 1 * _k, 1 * _k, 0, name player, 0, 0.04 * _k, "RobotoCondensed", "right", true, 0.005 * _k, -0.035 * _k ]; }];

As command syntax indicates, this command expects icon position in format PositionAGL meaning that over the land it expects PositionATL and over the sea PositionASLW.
This command works well with addon textures, however getting it to display mission textures is a bit tricky. Follow this guide.

You should rely exclusively on modelToWorldVisual for a moving object's icon position if you want it to accurately stay at the correct height over the sea. It computes faster than ASLToAGL.
Width, height, and textSize are proportional to the user's interface size, which can optionally be compensated against via size / (getResolution select 5)
Additionally, width and height are inversely proportional to the fovLeft and fovTop parameters from the user's ArmaProfile, and AFAIK those parameters are not retrievable via scripting. For example, a fovTop higher than the default value of 0.75 will make all 3D icons smaller vertically. I'm not sure if this is a bug or by design, however it is definitely annoying to take into account.

drawIcon3D and BIS_fnc_addStackedEventHandler work well together.
Using formatting commands with drawIcon3D will not work, instead, they will be added to the string.
["uniqueID", "onEachFrame", { drawIcon3D ["myIcon.jpg", [1,1,1,0.5], getPos player, 1, 1, 0, format ["%1\n%2", "Dreaded", "Entity"]]; }] call BIS_fnc_addStackedEventHandler;
Shown text will be Dreaded\nEntity. (A3 1.32.127785)

The "text" parameter must be a string. You cannot use Structured_Text.
