Default Arc Properties



The Get Info dialog and all of the commands in the Arc menu affect existing arcs, specifically those currently highlighted. To affect future arcs as they are created, use the Set Arc Defaults... command of the Info menu.

The dialog that appears allows you to set defaults for specific types of arcs or for all subsequently created arcs. When setting defaults for specific arcs (the top radio button) use the "Next arc" button to cycle through the desired types. When setting defaults for all arcs, use the "Reset to initial defaults" button to disable this overriding feature and resume individual arc type settings.

The rigid, fixed-angle, and slidable constraints may be controlled with this dialog, as can the negated, directional, and end-extension properties. It is also possible to specify the default width and angle for newly created arcs. The angle field is the preferred angle increment in degrees for newly created arcs (90 for Manhattan, 45 for Manhattan plus 45-degree angles, and 0 for any angle). The "Pin" is the default node to use when joining two of these arcs.
