In the 3D Environment (Model): The Point on Curve/Surface command creates a set of points on a selected curve or surface.
In the 2D Environment (Drawing): The Point on Curve command creates a set of points on a selected curve.
First you have to choose a Curve/Surface and select the point creation method from the Points drop-down list.
| By parameter |
Using this method, after selecting a curve specify the number of points to be created using the Points Along U option in the selection list. If the surface is selected — the Points Along V options enable you to specify the number of points to be placed in the respective directions. But the Points Along V option is de-activated for curves. Once you have specified the number of points, you can mention the start and end points for U, in the respective mini-dialog boxes that appear on the curve or surface. Take into account that if this method is selected and you have already picked a surface, then to change the method you will have to reset your selection. This is because of the fact that the By distance method applies only to curves and is not available for surfaces. |
| By distance |
Using this method, select a point on the curve (using the Point selector). Starting from this projection of the point on the curve, the number of points specified in Points Along U will be created on the curve, each at a distance from the previous one you can define in the Point Distance mini-dialog box (or specified by dragging the corresponding handle). When this method is selected, the Distribution mode under More Options is automatically set to Curvilinear and cannot be changed. |
The inserted points will never be placed beyond the curve, that is:
- The point distance will move only until the last point is inside the curve.
- The number of points will increase until the distance value allows the points to be placed on the curve.
Note
In case when no projection is found, a warning message — "No Projection" — is prompted. |
The Distribution option available under More Options in the selection list helps you to distribute the point entities in two different ways:
Point entities are positioned at equal parametric variations. The difference of the parameter value at two subsequent points is the same for any couple of points.
