Add Point

The Edit->Add Point command in the Model module allows you to add individual points to a curve, a face, or a polygon mesh object. For surface objects, it allows you to add rows of points in the U and/or V direction.

Procedure

1. Choose the Edit->Add Point command.
2. Select an object.
3. If you select a polygon mesh:

• Left mouse button adds a point after the last point.
• Middle mouse button adds a point between points.
• Right mouse button adds a point before the first point.

As the point is added, you can drag it to another spot to modify the shape of the polygon.

You can also add points using the Polygon->Vertex command.

4. On closed curves, all mouse buttons add a point on the curve where you click.

On open curves:

• Left mouse button adds a point after the last point.
• Middle mouse button adds a point between points.
• Right mouse button adds a point before the first point.

5. If you select a face:

• A point is always added between two points because a face is a closed object.

6. If you select a patch surface:

• Pick the location on a line in the direction (U or V) in which you want to add the row of points.
• Click any mouse button to add the row of points.

7. If you select a NURBS surface, the NURBS Add Row/Column dialogue box is displayed:

• Select the direction (U, V, or both) in which you want to add the new row of points. A magenta curve appears on the surface, perpendicular to the direction of the added points.
• Use the Location sliders to choose exactly the surface position in which to add the row of points.
• Click Add to add the row of points. You can continue adding rows using the Location slider and the Add button.
• Click Exit to accept the settings or Cancel to cancel the operation and exit the dialogue box.

You can also use the Effect->Subdivision command on NURBS curves or surfaces to add points or rows of points.
