Sketch, Doodle and Design to Scale Use Archisketch as you would a tracing pad. Sketch. Draw to scale. Layer over your sketch to further develop your ideas. Erase. Add symbols, colour, text and dimension lines. Import images or plans to set the scale. Zoom in without loss of quality. Rotate a shape, a layer, or the entire drawing to try different options. Visualize your ideas in 3D and see them in context. Use smart one- and two-point perspectives, and adjust your perspective grid and view point. Align your perspective to an image, and your lines automatically snap to the vanishing point. Print your drawings to scale up to A1 size, or export sketches to use in a CAD application or Adobe Creative Cloud. Archisketch is a scale-aware sketching program ideal for Architects, interior and landscape designers, product designers, design students, or anyone working with design on an iPad.
