Create a soft point
|
• Hold down SHIFT while you select and drag a free point to snap to the nearest geometric entity. When  Show Original is selected, you can snap to the original curve• Click > > and select and drag a free point to snap to the nearest geometric entity |
Graphics window
|
|
Move a soft point along a curve, edge, datum plane, or surface
Move a free point according to the movement constraint you set
|
Select and drag the point
|
|
|
Change a soft point reference
|
Select the soft point, right-click, choose Pick Soft Point, and select a new reference
|
|
|
Flip a soft point parameter to the opposite end of its reference
|
Select the soft point, right-click, choose Flip Soft Point. Also flips the direction of the soft point tangent when the first constraint is G1, G2, or G3.
|
|
|
Override the selected drag constraint to move a point in a straight line that is normal to the active datum plane
|
Hold down ALT while you select and drag a point
|
|
|
Override the selected drag constraint to move a point horizontally or vertically along the plane of the screen
|
Hold down CTRL + ALT while you select and drag a point
|
|
|
Delete points
|
• Select points, and press DELETE
• Select points, right-click, and choose Delete
|
|
|
Select multiple points along a curve between two selected points
|
Select a point, and press and hold down SHIFT while you select a second point along the same curve
|
|
|
Clear all point selections
|
Right-click and choose Deselect All Points when one or more points is selected
|
|
|
Nudge a point
|
Select a point and press UP ARROW, DOWN ARROW, RIGHT ARROW, or LEFT ARROW
|
|
|
Move a soft point to an exact location
|
Modify the Type and Value
|
Point tab of the Curve Edit tab
|
|
Move a free point to an exact location
|
• Specify X-, Y-, and Z-coordinate values
• Select the Relative check box to treat the x-, y-, and z-coordinate values as offsets from the original position
|
|
|
Place a soft point on a specific reference
|
Select a soft point, and do one of the following:
• Click the References collector
• Right-click the graphics window, and select Point Reference Collector
Then select a vertex, point, curve, edge, axis, datum plane, facet, or surface for the soft point to lie on
|
Point tab of the Curve Edit tab, under Soft Point
|
|
Offset a soft point from a plane to specify a distance along a reference
|
Select a soft point, and do one of the following:
• Click the Plane Reference collector
• Right-click the graphics window, and select Point Plane Collector
Then select a plane from which to offset the soft point
|
Point tab of the Curve Edit tab, under Soft Point
|
|
Nudge a point
|
• Select a point and click  ,  ,  , or  • Select a point and enter a value in the Adjust box |
Point tab of the Curve Edit tab, under Point Movement
|
|
Apply a dragging constraint to the selected point
|
Select a constraint from the Drag box
|
|
|
Apply an extend constraint to the nearest endpoint
|
Select a constraint from the Extend box
|
 |
• When you snap a free point of a planar curve or a curve on surface (COS) to a datum plane or to any another intersecting surface, an offset from plane soft point is created.
• To nudge a point using the arrow keys, you must first activate the graphics window. You cannot nudge a soft point.
• Planar curve points can only be dragged using the Free and Horizontal/Vertical methods. The Free drag method is the only one available for curve on surface (COS) curves.
