Tablet touch quick start

Eidograph uses one pointer-event model for touch, pen, and mouse. On a tablet you can construct, select, multi-select, animate, and save without a keyboard.

Prepare the layout

1. Use landscape orientation for more canvas and side-panel space.
2. Drag the right-panel splitter to resize it; the inner splitter changes the height of the Figures list.
3. If controls are small, choose L or XL in Settings › Appearance › Font size. This scales interface chrome, not the canvas or exports.
4. Fold the right panel when you want to focus on the canvas.

Core gestures

Gesture	2D canvas	3D canvas
Single tap	select or place a tool control point	select or place a 3D control point
Drag a free point	move in the plane and write coordinates	move on a camera-facing plane
Drag a bound point	move along its path	move on a linear carrier or sphere
Drag empty space	pan	orbit the camera
Two-finger pinch/move	zoom about the midpoint and pan	zoom and adjust the view
Long-press an object	enter touch multi-select	enter touch multi-select

If a second finger lands during drawing or a drag, the one-finger operation is cancelled safely and becomes a two-finger view gesture.

Draw in one gesture

With Segment, Line, Ray, Circle, or another two-point tool, press to place the first point, drag to see the live preview, and release for the second point. Tapping points separately also works. Arc and Ellipse need three control points; follow the previews in order.

With This project › Canvas & zoom › Auto-dock while dragging enabled:

• near a point, coordinates snap while the new point stays free;
• near a path, the definition becomes bound and later drags stay on that path;
• the candidate highlights before release, so move away to reject it.

Touch multi-select and bulk edits

Hold a canvas object or Objects-panel row still for about half a second. It joins the selection and sticky multi mode starts; later ordinary taps toggle more objects without a modifier key.

With two or more selected, the bottom bar offers:

• Edit… for shared color, opacity, and visibility;
• Delete for selected objects and their dependents;
• × to clear the selection and leave multi mode.

Tap empty space or press Escape to clear as well. Multi-select taps never turn into accidental drags.

Parameters and animation

Open Params to move the slider for every param; release writes the value into the script. The status-bar play, pause, and stop controls run animate; Stop writes the current animated values back to text.

Save your work

Choose Save from the project tab to write .eido. Before testing a new build or uninstalling, use Save As and place important files somewhere explicit. Download an example project to practise dragging and parameters on a tablet.
