Use editing grips to relocate or modify curves and tangents using visual design cues. If you created profile entities using the constraint-based tools, some editing grips are not available. For example, if you attach a floating curve to a fixed or floating tangent, the editing grip is not available for editing the PVI of the two entities.

Grip Type |
Behavior |
---|---|
at point of vertical intersection (PVI) |
Moves the PVI, changing grades and lengths of adjacent tangents. Preserves curve length and radius. Use with ORTHO mode turned on to move PVI horizontally or vertically. |
at end of tangent |
Adjusts the tangent length while preserving the grade. Modifies the grade of adjacent tangent. Preserves curve length and radius. |
at end of tangent |
Adjusts the tangent length and grade simultaneously. Modifies the grade of adjacent tangent. |
at tangent midpoint |
Moves the entire tangent, without changing the length or grade. Changes the location of adjacent PVIs and the grade of adjacent tangents. Preserves the radius and length of adjacent curves. |
at curve endpoint |
Moves the endpoint along the tangent, without affecting the tangent grades or PVI location. Changes position of both curve endpoints so that midpoint remains near PVI. Changes the curve length and radius. |
at curve midpoint |
Moves a pass-through point for the curve, changing the curve length, radius, and position of both endpoints as required. PVI location is not affected. After the curve is edited, this grip moves to the new midpoint. |
