There are two types of reference lines in Section Designer. They are line and circle reference lines. Sometimes you may find it useful to snap to a reference line. Other times you may want to align items to a reference line.
Reference lines and circles are initially drawn by
selecting the appropriate Draw menu > Draw Reference
Lines command or clicking the associated toolbar button, , and selecting the appropriate flyout toolbar button.
The geometry of the reference line is defined by the coordinates of the end points. To draw a reference line you left click once on the start point and once on the end point. You can then, if desired, right click on the reference line to bring up the Shape Properties form where you can modify its dimensions.
The geometry of the reference circle is defined by the coordinates of the center point and a diameter. To draw a reference circle you then left click once to draw the shape. The center of the shape is located at the location where you left click. The shape initially comes into Section Designer with default dimensions. You can then right click on the reference circle to bring up the Shape Properties form where you can modify its dimensions.
