Learn an action
Choose one of six plays and press Play action. Use the step rail, side breakdown or timeline to review a moment. Step pause stops at the end of each phase. 2D and 3D share the same positions and clock.
Read the court
Green numbered players attack; coral X-marked players defend. Solid lines show off-ball movement, wavy lines show dribbling, dashed lines show passes or shots, and a T marks a screen. Live drawing traces routes as the action unfolds; Full step reveals the complete current phase.
Draw your explanation
Press D or the pen icon. Draw freehand, drag an arrow, circle a zone, or place a screen marker. Choose a color and undo or redo. Your ink is anchored to the court and remains when you orbit, resize or switch 2D / 3D. Each play keeps its own annotations for this session. Opening a different file or reloading clears them.
Camera and exports
Drag to orbit; scroll or pinch to zoom. Coach, Top and Courtside frame the play. Player follows your selected player for a close look at the movements. Focus expands the workspace. The camera icon exports the current view, including ink; Export board image creates a high-resolution 2D board with the current annotations.

A note on the animation
The articulated characters illustrate running, dribbling, passing, receiving, screening, defensive slides and shooting. These are procedural teaching animations, not motion capture. Defender reactions and finishes are deliberately scripted; each play shows one read, not every possible response. Screens must be established before contact.
Everything needed to run this board is included in this file. No account, no remote assets, no uploads.
