Curve List: All the defined blank lines are added to this list.
Create: The program provides four methods to create curve: Free Curve, Rectangle, Circle/Ellipse and Sector. Refer to Section 7.5.5 for detailed description about Curve Editor.
Note: The created curve will automatically be projected onto the model mesh.
Select Line: Select a line, parameterize it to Free Curve and define it as trim line.
Input boundary: Define blank line by selecting the inner and outer boundary line of the model.
Output line: Export the line in the list. The line created here is the parameterized line in eta/DYNAFORM, which can only be selected and edited in the curve editor. If the user requires exporting line or editing line with curve tools, he/she must click Output line and transform the parameterized line to the line that can be used freely.
