Point on curve |
Scroll |
To snap an object’s characteristic point to another curve, use the Point on Curve 
command.
Step-by-step instructions
1.Select a curve to locate the point on. The name of the selected curve is displayed in the Object field on the Parameter Panel.
2.Select a point.
|
When working with a drawing please note that all the parameterized objects must belong to the same view. |
If the existing constraints do not prevent placing the point on the specified curve, then the image will be rebuilt, and after that the preset condition will be fulfilled. A Point on Curve constraint will be applied to the curve and the object that the indicated point belongs to.
3.To complete the command, click Finish 
.
Additional features for applying constraints...
The Point on Curve constraint can be created automatically when constructing objects in parametric mode. To do this, the Snaps option must be enabled in the Parametrize list when setting up the parametric mode. The parametric mode is configured for the graphic document in the section Parametrization settings dialog, and for a sketch in the model - in the section Sketch. The constraint will occur when entering a characteristic point of an object using the Point on Curve snapping, when constructing a circle using the command Circle center point on object, when placing points on a curve using commands Point on curve and Point at specified distance, and also when using editing commands that remove part of a curve from the point of its intersection with another curve (for example, Curve trimming) or vice versa, extend the curve to an intersection with another curve (for example, Extend to next object).
Constraints are displayed in the graphic area in the constraint preview mode. The point on the curve is shown by the symbol
