To Change the Soft Point Type
1. In the Model Tree, right-click the Style feature that contains the curve to edit and choose Edit Definition. The Style tab opens.
2. Click Style > Curve Edit. The Curve Edit tab opens.
3. In the Style Tree or graphics window, select the curve that the soft point lies on.
4. On the curve, select the soft point.
5. Click the Point tab, and then in the Type box, select a soft point type, or right-click the soft point, and choose a soft point option from the shortcut menu:
Length Ratio—Maintains the position of the soft point to the percentage of the length from the beginning of the curve to the point, relative to the total length of the curve.
Length—Determines the distance from the beginning of the referenced curve to the point.
Parameter—Maintains the position of the point by keeping its parameter along the curve constant.
Offset from Plane—Determines the position of the point by intersecting the referenced curve with a plane at a given offset.
 
* If multiple intersections are found, the value closest parametrically to the previous value is used.
Curve Intersection—Snaps the soft point to the intersection of two curves or two edges. Displays as an “x” in the graphics window.
Lock to Point—Locks the soft point to a defining point on the reference curve, finding the closest defining point on the parent curve, typically an endpoint.
Linked—Indicates that the point is a soft point, but that none of the above soft point types are applicable. This includes soft points on a surface or a plane and soft points to a datum point or vertex. For example, a curve point that is snapped to a surface is linked.
 
* Linked indicates a state; it is not an action.
Unlink—Disconnects the soft point from the parent geometry. The point becomes free and defined at the current location.
6. Type a value for the corresponding soft point type in the Value box.
7. To export the value for modification outside the Style feature, click the Value check box.
