RAY command
Creates rays.
Icon:
描述(D)
Creates a ray (semi-infinite line) from a combination of options including point, direction and angle.
Methods to begin a ray
This command has 6 methods to begin creating a ray:
- Start of ray
- 水平(H)
- 垂直(V)
- 角度
- Bisect
- 平行
You can continue adding unlimited rays until you press Enter to end the command.
- Start of ray
- Begin creating a ray by specifying the starting point of the ray then:
- 方向
- Specify the direction of the ray from the starting point.
- 水平(H)
- Begin creating a ray horizontal to the x-axis then:
- 位置
- Specify the starting point of the ray.
- 垂直(V)
- Begin creating a ray parallel to the y-axis then:
- 位置
- Specify the starting point of the ray.
- 角度
- Begin creating a ray based on an angle then:
- Enter angle
- Specify the angle of the ray.
- 位置
- Specify the starting point of the ray.
- Bisect
- Begin creating a ray which bisects the angle between two imaginary lines then:
- Set vertex point
- Specify the start point of the ray.
- 指定二等分角起点
- Specify a point to define the first imaginary line. The vertex is used as the other point.
- 指定二等分角终点
- Specify a point to define the second imaginary line. The vertex is used as the other point.
- 平行
- Begin creating a ray parallel to a line or polyline segment then:
- Set offset distance for parallel infinite ray
- Specify the offset distance for the ray.
- Select entity for parallel infinite ray
- Select a line or polyline segment from which to offset the ray.
- Side for parallel infinite ray
- Specify the side on which to place the ray. The ray’s start point is parallel to the line’s start point.
Options within the RAY command
After you begin creating a ray, the following options may be available:
- 参照
- Select an entity to use a reference angle then:
- Enter angle
-
Specify the angle to place the ray relative to the selected entity.
- 位置
- Specify the starting point of the ray.
- 位置
- The Location prompt repeats so that you can draw more angled rays with different starting points. Press Enter to end the command.
- 实体
- Select a line, arc, a polyline segment to bisect then:
- Select side for ray bisection
- Specify the side on which to place the ray.
- 通过点
- Specify a point through which to draw the ray.
- Select entity for parallel infinite ray
- Specify the entity to offset with the ray.
- 指定通过点
- Specify the point through which to draw the ray. This point is the ray’s start point.
