Point - On Surface

Purpose:

To create or modify a point on the default surface.

Prerequisites:

None.

Instructions:

• In create mode, two of the point co-ordinates must be entered. Optionally, the third one may be entered as an "approximate" co-ordinate. In case of ambiguities, the system will use this co-ordinate to determine the location in the surface. The exact value of the third co-ordinate will be automatically calculated when you press the Ok button. Apply has the same function as the Ok button, but keeps the form open for input of another point.

• In modify mode, the point definition may be changed. Select Type lets you change the point into another type (three co-ordinates or point in the intersection between a curve and a plane). Select Surface lets you select another surface to use in the point definition.

Options:

Not available.

Result:

• In create mode, a new point at the given location will be created and selected.

• In modify mode, the selected point will be updated with the new definition data.
