Under Windows, no installation is required. After downloading solvespace.exe, you can run it immediately. If you wish to continue using SolveSpace, then save solvespace.exe somewhere convenient (e.g., on your desktop).

Under OS X, run the .app file directly from the disk image, or drag it to Applications to install. Under Linux, build and install, or get SolveSpace through your distribution's package manager.

Files saved by 2.3 are usually readable by 2.0, but some new features are unsupported in older versions.

Quick start: The first time SolveSpace runs, you will see an empty workplane.

• To draw a line, choose the Sketch → Line Segment (or circle, or arc, or ...) menu. Then left-click to define the endpoints. Hit Escape if you want to stop drawing before you've formed a closed contour.
• Right-drag to pan, center-drag to rotate, and mousewheel to zoom. To align the view's rotation back to the workplane, choose View → Align View to Workplane.
• To select a line, hover the mouse over the line (it turns yellow), and left-click (it turns red). To dimension the line's length, choose Constrain → Distance / Diameter.
• To move the dimension, drag it. To change the dimension, double-click it, type a number, and hit Enter.
