Snap to Grid

[gwpriester]

If you hold down the Ctrl key, lines will be constrained to the angles that you have set in Page Options > General. Xara usually sets this angle at 45 degrees. But you can select other angles (I use 15 degrees), or set your own. For example, 72 degrees if you want to draw a star.

There is also an Isometric grid option (right click on the rulers and select Grid and Ruler Options. It is not a true isometric grid. There is a reason for this but I have forgotten a long time ago why.
