Help geometry with respect to points or cursor position

Group of geometric features and characters that are visible on the screen only. Help geometry will not be printed or exported. Use these functions to determine, for example, an intersection or to define a reference point. The various functions are divided into three different groups.

• Help geometry with respect to points or cursor position
• Help geometry with respect to a reference line
• Help geometry with respect to reference circle/arc
