ModelSpinner

ModelSpinner is a toggle: one command to open, the same command to close. The wheel appears as a floating overlay that follows your cursor.

1. Type SPIN in the command line — or press the hotkey (default: F4).
2. The wheel appears near your cursor. It follows you with a soft leash — move the cursor away and the wheel drifts along.
3. Click any section on the wheel to rotate the viewport.
4. To close: type SPIN again, press the hotkey, or press Escape.

The eight sections around the wheel give you instant access to preset and custom rotation angles. Every rotation uses DVIEW → Twist followed by UCS → View, so your UCS stays aligned with the screen.

1. 90° Left / 90° Right — rotate the view by exactly 90° counterclockwise or clockwise.
2. Custom Left / Custom Right — rotate by your custom angle (default 45°, configurable in Settings).
3. World (center button) — reset the view twist to 0°, aligning with the World Coordinate System.
4. Restore (⚓) — go back to the exact twist angle that was active when you opened the spinner. Useful as a quick undo.

The most powerful feature: pick two points in the drawing and ModelSpinner aligns the view so that the line between those points is either horizontal or vertical on screen.

1. Click Pick 2p on the wheel. The spinner hides and you get a point prompt.
2. Click the first point — typically one end of a wall, road, or building edge.
3. Click the second point — the other end. A rubber-band line shows the direction.
4. ModelSpinner calculates the angle and rotates the view so the picked line appears horizontal (default) or vertical on screen.
5. The measured angle is saved. The spinner reappears with the updated Recall value.

After using 2-point alignment, the measured angle is stored in settings and survives across sessions. Click Recall to re-apply it at any time — even in a different viewport or after restarting AutoCAD.

1. The Recall section shows the last measured angle (e.g. "−23.4°").
2. Click it to apply that exact twist to the current viewport.
3. This is useful when you've rotated back to World and want to return to the building's angle without picking points again.

The small triangle on the edge of the wheel indicates the drawing's Project North direction (based on NORTHDIRECTION + ANGBASE). Clicking it rotates the view to align with Project North.

1. The Project North triangle moves around the wheel's edge in real time, showing where North is relative to the current view twist.
2. Click the triangle to rotate the view so that Project North points up on screen.
3. The compass needle in the center also updates with an elastic animation, giving visual feedback of the current orientation.

In paper space, viewports are often locked to prevent accidental zooming or panning. ModelSpinner detects this and handles it gracefully.

1. If the active viewport is locked, ModelSpinner shows a red overlay: "Viewport locked! Unlock temporarily?".
2. Click ✓ to temporarily unlock the viewport. The spinner opens with full functionality.
3. Click ✕ to cancel — the viewport stays locked and the spinner closes.
4. When you close the spinner, ModelSpinner automatically re-locks the viewport.

Click the ⚙ section on the wheel to open the Settings dialog. It shows a live preview of the wheel with your changes.

1. Custom angle — the angle used by the two custom rotation sections (default: 45°). Enter any value.
2. 2-point alignment — choose H (horizontal) or V (vertical) for how the 2-point pick aligns the view.
3. Hotkey — click the button and press any key to assign a new hotkey. Default: F4.
4. Wheel size — slider with three sizes: Small (120px), Medium (160px), Large (200px).
5. Wheel opacity — slider from 20% to 100%.
