Point - On Surface

Purpose:

To create or modify a point on the default surface.

Prerequisites:

None.

Instructions:

• In create mode, two of the point coordinates must be entered. Optionally, the third one may be entered as an approximate coordinate. In case of ambiguities, the system will use this coordinate to determine the location in the surface. The exact value of the third coordinate will be automatically calculated when the user pressed 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 the user change the point into another type (three coordinates or point in the intersection between a curve and a plane). Select Surface lets the user select another surface to use in the point definition.

Options:

None 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.
