Curved Dashed Tool
This tool allows you draw a dashed curved line.
This is typically used for connecting electrical symbols. In this case, the tool is simply the WildTools B-spline tool installed here and set up to draw two styles of dashed lines.
The Projection Line tool closely emulates the process most draftsmen use on a drawing board. You establish a reference line, and when you click on the drawing, projection lines are drawn perpendicular to the reference line. This allows you to set up a view in any direction.
When you select the too, the reference line will be shown as a 'crawling' gray line.
To change the reference line, hold down the Option key and click on any line in the drawing, or the side of a rectangle or polygon. The object that you option-click may be inside a group.
In the tool's dialog, you set whether the tool will place a fixed-length projection line, a line extending from the click-point to the reference line, or a point on the reference line.
To place a projection line, you click in the drawing.
