Shell Curve - Combined

Purpose:

To create or modify a curve as a combination of two intersecting curves.

Prerequisites:

None.

Instructions:

• In create mode, the user will be prompted to indicate two curves. Any curves already selected will be used as input to this function. When two curves have been selected, the user must indicate what part of each curve to use for the combined curve. After this, the curve will be created by the selected parts of the two curves. Note that the curves must intersect.

• In modify mode, the curve may be changed. Select Type lets the user change the curve into another type (intersection between surface and plane, intersection between surface and general cylinder or parallel curve). By use of the button Modify Box the extension of the curve can be changed.

Options:

None available.

Result:

• In create mode, a new shell curve will be created and selected.

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