About This Tool
Paper for three-dimensional sketches
An isometric grid provides three drawing directions: vertical and two diagonals at 30 degrees to the horizontal. Use the equilateral triangles or their corner dots to keep parallel edges aligned when sketching cubes, furniture or mechanical parts. This tool generates blank paper; it does not draw or measure your objects.
