Construction Line Tool Options

The following tool options are available:

Draw from center Start your sketch from the center or midpoint.
Automatically create constraints Select this sketch option to automatically generate constraints based on shapes created or on snaps. This option is enabled by default.
Snap to grid Select this sketch option to turn snapping on or off while sketching. The cursor will snap to the minor grid spacing increment while you sketch. The defaults are 1mm for Metric and 0.125in for Imperial units.
Snap to angle Select this sketch option to turn angle snapping on or off while sketching. The cursor will snap to the angular snap increment while you sketch. The default is 15 degrees.
Fit Curves Disable this mesh option if you do not want the system to fit curves through the points.
Tolerance This mesh option determines how many points will be found, which also determines how many curves will be created. The smaller the tolerance, the more points will be found and the curves will be generated.
Auto-merge When this mesh option is enabled, the system will merge lines and arcs to form splines. Splines are displayed pink.
