Join Dialog
-
Use the Browse... button to access an Open Design dialog to populate the Join with edit box.
-
If required, select the Save As check box and enter the required design name for the merged design.
-
Use the Join at dropdown list to select the required curve type (either SECTION, PLINE or TANGENT) and then choose the particular curve from the dropdown list.
-
To perform the operation click the Join button.
If two curves with the same name or position exist in the two designs and have a common intersection point, they will be joined and any discontinuity at the join will be removed. If no common intersection exists then the following actions are taken:-
-
Knuckles, tangents, Pines, diagonals, Clines, patches, - The curve from the joining design will be stored with the character "1" appended to the name. If this curve also exists, then the character "2" will be tried and then "3", and so on. If the curve name is 8 characters long then the 8th character will be replaced with "1", "2",
-
Boundary curves - The curve from the joining design will be saved as a Tangent curve.
-
Waterlines, buttocks - The curve from the joining design will be stored as a Pline with name "Wposition" or "Bposition". For example, Waterline 2.5 in the joining design which has no common intersection with Waterline 2.5 in the current design will be saved as Pline W25000.
Patch definitions only are merged into the current design. The Patches will need to be refitted by the user.
