Adding and deleting points |
Scroll |
When creating 3D spline, spline on surface or broken line delete specified points and add new ones to existing parts of the curve (segments of the broken line). These actions are performed in the editing mode.
To add a point to a segment of a curve (broken line), use the buttons above the Point parameters table. To do this, select a point to add the new point to, and then click the corresponding button. A new point will appear in the graphic area, and a row with its parameters will appear in the point parameters table.
For description of buttons, see the table.

Description |
|
|
Insert vertex before current one |
You can add a point between he current point and the previous point. The new point gets the number of the current point, and numbers of consecutive points are incremented by 1. You can also add a new point by pressing the <Insert> key. |
|
Duplicate vertex |
You can add a new point with the same coordinates (and with the same weight, for a spline by poles) as the current point. The new point gets the number of the current point, and numbers of consecutive points are incremented by 1. |
|
Insert vertex after current one |
You can add a point between he current point and the next point. The new point gets the number next to the number of the current point, and numbers of consecutive points are incremented by 1. |
Deleting points
You can delete curve points both in curve creation and in curve editing modes. More information about modes...
To delete a point in Creation mode, hover the mouse over the row Point parameters table, corresponding to this point, and click the "x" icon in the appropriate row, which appears in this line.
To delete a point in Edit mode, select it in the graphic area or in the points parameters table, and press the Delete button 
above the table or the <Delete> key. You can use the same way to delete several points at the same time by selecting the corresponding rows in the table.
After the points are deleted, the object is redrawn according to the position of the remaining points.
