Point parameters table |
Scroll |
Each point of a spline or broken line is defined by a set of parameters. Their values are displayed in the point parameters table in the vertex Coordinates group on the Parameter Panel.
This table contains the following parameters:
•point position parameters:
•for 3D splines and broken line — point coordinates (for spline by poles — coordinates of the vertices of its defined broken line;
•for spline on surface — values of the U and V parameters;
•icons of links and constraints applied to the curve points;
•advanced options:
•for spline by poles: point weight;
•for broken line: vertices fillet radius.
The row numbers in the table correspond to the order of points on the curve. Each row contains the parameters of one point. You can use arrow keys to navigate between rows.
When you define points, their parameters are automatically entered into the table. A new row is created for every point. In editing mode, you can modify the point parameters in the table. This mode is enabled automatically when any row of the table becomes active.
If a setting cannot be edited, its cell has gray background. For example, you can only change the coordinates in the table if the points were plotted By coordinates and if they are not linked to a point object or specially plotted point.
The cells of the point parameters may be populated manually or automatically. For example, when you drag a point with your mouse or enter its coordinates in the Coordinates field, the coordinates of the point in the table will be modified automatically.

You can set same parameter values for several points at the same time using the table and the fields on the Parameter Toolbar. Use the following procedure. Select the rows of the points in the table. The Vertex Design group fields will contain the parameter values corresponding to the top selected row. Enter the required parameter value in the Vertex Design groups (not in the table cell). This value will be propagated to all cells of this parameter selected in the table. |
Using the buttons above the table, you can perform several actions with points and their parameters:
•save point parameters to a file and read them from file (except for surface spline),
•add point groups (except for surface spline),
•undo the spline shape change in points,
•delete associative links (except for spline on surface).
The set of buttons depends on the ability to perform the corresponding operations as well as current command operation mode.
Displaying relations and restrictions
All links and restrictions applied to the curve points are marked with special icons in the cells in the Connection column (the point is displayed in the header of this column).
Icons and their values are shown in the table.
Point relations and restrictions

Description |
|
|
A point on a curve is associatively related to a point object of the model. |
|
|
A point on curve is specified while building a special point and it has an associative connection with it. This link is automatically created when the special point is plotted using any method except for By coordinates. More details on the associative link with a plotted point... |
|
|
The movement of a point of spline by poles (spatial or surface) is restricted. This restriction depends on the mating of the spline in one of its terminal points. Depending on the selected mating condition, the restrictions may apply to one spline point (adjacent to the terminal point) or to two points: the adjacent point and the next one. For details on mating of the spline by poles with objects, see section Notes on mating of the spline by poles with model objects. |
You can use the table cells with the icons of the relations to remove these relations. To delete a link of a curve point with a point object of the model or with a specially plotted point, please click the corresponding cell in the Connection column.
Please note that once an associative link is deleted, you cannot restore it or create a new one using the point parameters table. To do this, you need to specify a point object again or plot a point.
