Creating Perpendicular Line on Selected Shape
Select a shape located on the drawing to create a perpendicular line based on the shape.
Shapes that can be used as a base are lines, polylines, infinite lines, rays, circles, arcs, ellipses, elliptical arcs and B-Splines.
The following 2 methods can be used to create a perpendicular line.
- If the coordinates for the foot of a perpendicular line are fixed, select a "shape" to be used as a base, and specify the "foot point of a perpendicular line" and "end point."
- If the coordinates for the foot of a perpendicular line are not fixed, specify the "start point" and select a "shape" to be used as a base.
To display a command parameter to be executed, click 
/ 
of command parameters, or press Tab key or ← / → key on the keyboard.
- Point [Line] on [Shape] menu, and click [Perpendicular Line].
Then you will be able to create a perpendicular line.

When coordinates for the perpendicular line intersect point are fixed
- Switch the parameter on Command Window to [Base Shape], and click a shape to be used as a base.
- Click the foot point of a perpendicular line on the drawing.
- Click the end point of the perpendicular line on the drawing.
A line to connect the foot of the perpendicular line and end point will be created.
A line to connect the foot of the perpendicular line and end point will be created.
- Switch the parameter on Command Window to [Start Point] box, and click the start point of a perpendicular line on the drawing.
- Click a shape to be used as a base.
A perpendicular line connecting the start point and selected shape will be created.
