2D DRAW

Select — tap a shape to select it, drag it to move it. Drag empty canvas to pan. A selected shape's exact numbers can be edited in Properties on the right. Shift+tap picks several shapes at once (they all light up gold) — then Delete removes them all in one go.

Line — tap the start point, tap the end point.

Rect — tap one corner, then the opposite corner (squares and rectangles).

Circle — tap the center, then a point on the edge to set the radius.

Arc — tap the start, a point on the curve, then the end. 2D DRAW solves the true radius through all three points.

Spline — tap points for a smooth freeform curve; double-tap (or ✓ Finish) to end it.

Cut — split a shape right where you tap: lines, rectangles, circles, arcs and paths divide into two pieces there (a circle breaks open into an arc).

RAD — round a corner for real: tap two lines that meet, type the radius, and both lines are trimmed back with a true arc fitted in. Nothing extra is left behind. Rectangles work too — tap one right at a corner and its two edges are picked for you.

Chamfer — the same two-line pick, but the corner is cut straight across at the distance you type.

Offset — tap a line, circle, arc or rectangle, type the distance, then tap the side where the parallel copy should go. Circles and arcs grow or shrink around the same center.

Measure — tap two points and the exact distance shows on the canvas and on the right, with ΔX and ΔY. Near a shape it snaps exactly: the CENTER of circles, squares, lines and arcs first, plus ends, midpoints and radius points — watch for the blue ring and its label so you always measure the point you meant.

Pan — drag to move around the canvas. Pinch with two fingers zooms; the mouse wheel zooms at the cursor.

Fit — zoom so the whole drawing fits the screen, centered.

Views — Top / Front / Side / Iso — see your drawing from the front, from the side, or tilted in isometric, like the simulator's graph views. Views are display only: the drawing, its numbers and its exports never change, and you can keep drawing and editing in any view.

Mirror — flips the selected shape over its own center, left–right or top–bottom.

Copy — duplicates the selected shape, nudged over a touch so you can drag it into place.

Rotate — turn the WHOLE drawing around its center: one-tap 45° / 90° / 180° / 270° or type any angle (negative turns the other way).

Snap — when on, points you place click onto the grid (half a grid step) so numbers stay clean. Measure's shape snapping works either way.

Dims — show or hide the size labels drawn on each shape (Ø, R, lengths, W×H). The header pill does the same — handy for a clean look at the layout.

Undo / Redo — step back or forward through your changes.

Delete — removes the selected shape. 🗑 Clear wipes the canvas (Undo brings it back).

Open — DXF drawings (circles and radius arcs read true, bulges included — a round made of arc pieces reads as ONE full circle), .json drawings you saved here, and .pim / .nc / .gcode programs, which plot as their toolpath.

Save As… — the name decides the format: .dxf (default, opens anywhere), .json (re-open it here later), .png (a picture).

Save as PNG — quick picture of the canvas.

Send to Generator — sends this drawing to the G-code Generator: part size, bolt circles and holes pre-fill, and the ✒️ Profile tab cuts your exact outlines with true G2/G3 arcs and complete circles.

IN / MM — switches the labels only; the drawing itself never rescales. Opening a DXF sets it from the file.
