SETUP

To start working with DrawDebugTools DDT is very easy. 

Drag and drop DDT prefab in your scene:

Call drawing functions from your code.

EXAMPLE

This is an example of drawing a sphere, grid, and a 3d text:

Code :

DrawDebugTools.DrawGrid(Position, GridSize, 1.0f, 1.0f);
DrawDebugTools.DrawSphere(Position, 1.0f, 12, Color.Green);
DrawDebugTools.DrawString3D(Position, Rotation, “SPHERE”, TextAnchor.LowerCenter, Color.White, 1.5f);

The signatures of the functions used are:

DrawDebugTools.DrawGrid(Vector3 Position, float GridSize, float CellSize, float LifeTime = 0.0f);
DrawDebugTools.DrawSphere(Vector3 Center, float Radius, int Segments, Color Color, float LifeTime = 0.0f);
 DrawDebugTools.DrawString3D(Vector3 Position, Quaternion Rotation, string Text, TextAnchor Anchor, Color TextColor, float TextSize = 1.0f, float LifeTime = 0.0f);

The tool is available on asset store:
