Square Sketch — Manual

Basics

Foreword

You don't need this manual for your first drafts, as the built-in tutorial explains the most important things step by step in a sensible order.

This manual is intended as a reference once you have completed the tutorial and for further study.

Drawing area

The drawing area has no boundaries. You can start your draft anywhere and expand in any direction.

However, if you want a border for orientation or to maintain a fixed size, you can place a frame.

You can also place multiple frames next to each other to divide the drawing area.

Frame

A frame is a rectangle that contains and delimits a draft or a part thereof.

You can draw a frame from lines yourself or use one from the examples.

When exporting or printing, the frame is invisible if Lines at margin is set to Hide.

Grid

When you zoom in, the grid is automatically refined in two steps: first 1/2 and then 1/8.
