Isometric paper on iPad

Isometric paper is graph paper for drawing in 3D. On iPad you skip the printer, pick the lattice size you want, and your lines can snap to it.

What isometric paper is

Height goes up; width and depth follow the diagonals.

Its three line sets match a box’s three edges, so sizes count in lattice steps, with no perspective to work out.

Why draw it on iPad

Fresh sheets, snapping, undo, three densities.

A pad holds up to 50 pages, and snapped lines stay true when you draw fast.

How to sketch on isometric paper

Block in the box

Carve out features

Angled cuts last

Circles: ellipses

Put both ends of a slope on lattice points. Then size it: How to dimension an isometric drawing.

Choosing a lattice size

One 2 × 2 × 2 cube, three sizes.

Small fits more detail; Medium is a good default; Large blocks in big shapes fast.

Other papers in the same app

Ringed papers snap lines to them.

Grid and dot grid suit flat views and floor plans. Change paper anytime from More.

Isometric paper in PencilCAD

Line snaps and welds; Ink fills a closed shape.

Open More and choose Isometric: Small, Medium or Large.
Tap the toolset chip beside the page count and choose CAD, or use Settings → Tools, then drag with Line.
For a free line, tap Snap (the magnet) at the top right and turn off Snap to grid.
Add sizes with Dimension.
In Sketch, drag a color from Ink onto a closed shape.
