3D Spline PropertyManager
The 3D Spline
PropertyManager controls the following properties of a sketched
3D Spline:
Existing Relations
Relations . Displays relations inferenced automatically
during sketching or created manually with Add Relations. When
you select a relation
in the list, a
is highlighted in the graphics area.
Information
. Displays the status
of the selected sketch entity (Fully
Defined, Under Defined,
and so on).
Add Relations
You can add relations
between spline points, between spline handles, and between spline handles
and external sketch entities. Selections
appear when the relevant geometry exists in the sketch.
Options
When Maintain Internal Continuity
is cleared,
the curvature scales down abruptly. |
|
When Maintain Internal Continuity
is selected,
the curvature scales down gradually. |
|
Parameters
Specify any appropriate
combination of the following parameters to define the spline if the spline
is not constrained by relations.
|
Spline
Point Number. When you
scroll through the points, the corresponding coordinates appear below |
|
X Coordinate. The x coordinate of the spline point. |
|
Y Coordinate. The y coordinate of the spline point. |
|
Z Coordinate. The z coordinate of the spline point. |
|
Tangent
Weighting1. Controls the left
tangency vector by modifying the spline’s curvature at the spline point. |
|
Tangent
Weighting 2. Controls the right
tangency vector by modifying the spline’s curvature at the spline point. |
|
Tangent
Radial Direction. Controls the tangency direction by modifying
the spline’s angle of inclination relative to the X, Y, or Z axis. |
|
Tangent
Polar Direction. Controls the elevation angle of the tangent vector
with respect to a plane placed at a point perpendicular to a spline point. |
|
You can also dimension to spline handles.
|
|
Tangent
Driving. Enables spline control using Tangent
Weighting, Tangent Radial Direction,
and Tangent Polar Direction. |
|
Reset
This Handle. Returns the selected spline handle to its initial
state. |
|
Reset
All Handles. Returns all spline handles to their initial state. |
|
Relax
Spline. When you first sketch a spline and display the control
polygon, you can drag any node on the control polygon to change its shape.
If dragging results in a spline that is not smooth, you can re-select
the spline to display the PropertyManager and click Relax
Spline under Parameters
to re-parameterize (smooth) the shape. The Relax
Spline command becomes available again by dragging a node on the
control polygon. |
|
Proportional. A proportional spline retains its
shape when you drag the endpoints; the entire spline resizes proportionally.
You can add dimensions and relations to internal points of proportional
splines. |
