Ray
The Ray tool creates a ray defined by an initial endpoint and extending infinitely in a specified
direction.
Note: You can constrain the slope to 15-degree increments by pressing the
creating or modifying a ray.
Creating a ray
1.
Select Ray from the Lines toolbox.
2.
Click to create or select the initial endpoint of the
ray.
3.
Position the ray in the desired orientation, and click
to specify direction and slope.
If the ray is created in free space, a point is not
created. If the ray is not in free space, it is attached
to a second point.
Modifying a ray
Translate a ray without changing its direction and slope
by selecting the Pointer tool from the Pointer toolbox.
Then using the Pointer :
4
For a ray constructed with a single point, drag
the point.
4
For a ray constructed with two basic points, grab
the ray away from the points and drag.
Change the direction and slope of a ray using the Pointer
tool:
4
To change a ray constructed with a single point,
grab the ray away from the point and drag. Press
the
SHIFT
increments.
4
To change a ray constructed with two basic
points, drag either of the points.
4
Changing a ray constructed with a dependent
point is relative to the object to which it is
attached. You may drag the object or the point,
depending on the construction.
