Ray

Start of ray

Specifies the starting point of the ray.

Pick a point in the drawing, or enter x,y coordinates; prompts you:

Direction - specify the direction of the ray.

The Direction prompt repeats so that you can draw multiple rays from the same starting point.

Press Enter to exit the command.

Bisect

Draws a ray that bisects entities perpendicularly; prompts you:

Entity/<Vertex point> - enter an option.

Entity

Draws rays perpendicular to the midpoint of lines and polyline segments, and the center point of arcs and polyarcs; prompts you:

Select line,arc, or polyline segment to bisect - select a line, an arc, a polyline segment, or a polyarc.

• Line or polyline segment - draws ray perpendicular to the segment's midpoint:

• Arc or polyarc - draws ray perpendicular to the arc's center point and through its midpoint:

When you select a line or polyline segment, Bricscad prompts you:

Select side for ray bisection - choose the side on which the ray should emerge.

The 'Select line,arc, or polyline segment to bisect' prompt repeats so that you can draw rays on other entities.

Press Enter to exit the command.

This option works with splined polylines, but not with spline entities.

Vertex point

Draws rays that start at the vertex point and bisect two pick points; prompts you:

Bisection angle start point - specify one part of the bisection angle.

Bisection angle start point - specify  the other part of the bisection angle.

Horizontal

Draws rays horizontal to the current UCS; prompts you:

Location - specify the horizontal location of the ray; pick a point in the drawing, or enter x,y coordinates.

The 'Location' prompt repeats for drawing multiple horizontal rays at different starting points.

Press Enter to exit the command.

Vertical

Draws rays vertical to the current UCS; prompts you:

Location - specify the vertical location of the ray; pick a point in the drawing, or enter x,y coordinates.

The 'Location' prompt repeats for drawing multiple vertical rays at different starting points.

Press Enter to exit the command.

Angle

Draws rays at angles; prompts you:

Reference/<Enter angle (0)> - enter an option.

Reference

Draws rays at an angle relative to another entity; prompts you:

Select reference entity - choose a line. The line provides the reference (base) angle.

Enter angle - specify the angle, measured relative to the entity.

Location - specify the angle's start point; need not coincide with the entity's end points.

The 'Location' prompt repeats for drawing multiple rays at the same angle.

Enter angle

Specifies the angle; enter an angle or pick two points to indicate the angle; prompts you:

Location - specify the starting point of the ray.

The 'Location' prompt repeats for drawing multiple rays at the same angle.

Parallel

Draws rays parallel to lines and polyline segments; prompts you:

Through point/<Offset distance for parallel infinite line> (Through) - enter an option.

This option works only with line segments.

Through point

Specifies the point through which to draw the ray; prompts you:

Select entity for parallel infinite line - choose the entity to offset with a ray.

Through the point - specify the point through which to draw the ray; this point also specifies the ray's start point.

Offset distance for parallel infinite line

Specifies the offset distance.

Enter a value or pick two points; prompts you:

Select entity for parallel infinite line - choose the entity to offset with a ray.

Side for parallel infinite line - specify the side on which to place the ray.

The ray's start point is parallel to the line's start point.

The 'Select entity for parallel infinite line' prompt repeats for drawing multiple rays at different offset distances.

Direction

Specifies the direction of the ray.

Pick a point, or enter x,y coordinates.
