CAD > Snap > Trace Cloop Snap

Snap to all corners along a construction line segment. This snap mode can be used as a quick method for building DDLoops ( CAD > Build > DDLoop) and FFLoops ( CAD > Build > FFLoop) and Tunnels ( CAD > Build > Tunnel).

To use this snap mode you simply pick a single points on the desired construction line segment and all points on this line will be automatically selected. For example if you select point 4, points 5, 6, 7, 8, 1, 2 and 3 will automatically be selected.

Notes:

The location of all points along construction lines can be viewed by setting the View > Render > Cline dot radius parameter.

Before using this trace snap mode, construction lines should be cleaned up using the CAD > Pack and Renumber Clines function.

The CAD > Edit > Smooth Construction Lines function can also be used to aid in cleaning up construction lines.
