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
SHIFT
key when
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.
Create a point.
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.
Click to specify the slope.
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
key to constrain the slope to 15-degree
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.
