Ray

Toolbar: Draw 2D > Ray ()

Menu: Insert > Ray

Keyboard: RAY

Experience Level: Intermediate

Draws an infinite line in one direction from or through a specified point.

 

  1. Select the start point of the ray.
  2. Select the direction of the ray.

Infinite ray: Bisect Horizontal Vertical Angle Parallel <Start of ray>: To draw a ray using a point and direction, specify the starting point of the ray. To draw a ray that bisects a point or entity, choose Bisect. To draw a ray in a horizontal direction, choose Horizontal. To draw a ray in a vertical direction, choose Vertical. To specify the angle of the ray, choose Angle. To draw a ray parallel to another entity, choose Parallel.

Direction: Specify the direction in which you want to draw the ray.

Direction: Specify the direction in which you want to draw another ray. The second ray is drawn from the same starting point as the first ray. You can continue to draw rays by specifying directions. To stop drawing rays, right-click the mouse or press Esc.

To draw a ray that bisects a point or entity

 

  1. Specify the point to bisect.
  2. Specify the start of the bisect angle.
  3. Specify the end of the bisect angle.

Choose Bisect.

Entity <Vertex point>: Specify a vertex point for the ray to bisect. To select an entity to bisect, choose Entity.

Bisection angle start point: Specify the start of an angle.

Bisection angle end point: Specify the end of the angle.

To select an entity to bisect

Choose Entity.

Select line, arc, or polyline segment to bisect: Select the entity you want to bisect. You can only bisect lines, arcs, or polylines.

Select side for ray bisection: Select the side from which you want the ray to project. The ray is created perpendicular to the entity. You can continue selecting entities to bisect.

To draw a horizontal ray

 

  1. Specify the start point of the ray.

Choose Horizontal.

Location: Specify the starting point (left side) of a horizontal ray.

Location: Specify the starting point of a second horizontal ray. You can continue to draw horizontal rays by selecting starting points. To stop drawing rays, right-click the mouse or press Esc.

To draw a vertical ray

 

  1. Specify the start point of the ray.

Choose Vertical.

Location: Specify the starting point (bottom) of a vertical ray.

Location: Specify the starting point of a second vertical ray. You can continue to draw vertical rays by selecting starting points. To stop drawing rays, right-click the mouse or press Esc.

To draw a ray by specifying its angle

 

  1. Specify the start point of the ray and an angle.

Choose Angle.

Reference <Enter angle (45°)>: To accept the default setting for the angle, press Enter, or enter a new value. To specify an entity to use as a reference point, choose Reference.

Location: Specify the starting point of a ray.

Location: Specify the starting point of a second ray. You can continue to draw rays by selecting starting points. To stop drawing rays, right-click the mouse or press Esc.

To draw a ray using an entity as the reference point for the angle

 

  1. Select the reference entity.
  2. Select the start point of the ray and specify the angle.

Choose Reference.

Select reference entity: Select the entity you want to use as a reference point for the angle.

Enter angle: Enter an angle at which to draw the ray, measured from the reference point in the direction defined on the Drawing Units tab of the Drawing Settings dialog box.

To draw a ray that parallels an entity

 

  1. Select the entity you want to parallel.
  2. Select the side for the ray.

Choose Parallel.

Through point <Distance for parallel infinite line> (2.5000): To accept the default setting, press Enter. To specify a point from which you want the ray to project into infinity, choose Through point. To specify the distance from an entity that you want the ray drawn, enter a value.

Select entity for parallel infinite line: Select the entity that you want the ray to parallel.

Side for parallel infinite line: Select the side of the entity where you want to draw the ray.

To select the through point

Choose Through point.

Select entity for parallel infinite line: Select the entity that you want the ray to parallel.

Through the point: Select the point from which you want the ray to project into infinity.
