By Layout: Assign a curve library to alignment in a layout. The assigned Curve library will be updated to reflect the shape of the alignment in the layout.

By Select: Assign a curve library to a line object.

By Draw: Draw a line and at the same time assigns a curve library to that line. The draw function comes with some of the sketch functions.

Layoutwise: If it is checked on, the whole alignment will be selected as one line and a curve library will be assigned to that line.

Options
The options below are activated when ‘Assign library> By Layout or By Select’ is selected.
- From Start: Assign a curve library in a forward direction (from the start to the end).
- From End: Assign a curve library in a backward direction (from the end to the start).

Offset-y: Apply offset value in the y-axis based on the line to assign.

Offset-z: Apply offset value in the z-axis based on the line to assign.

Rotation-x: Input the rotation angle in the x-axis(Based on the positive direction of a line object to be assigned).

Rotation type
- All: Rotate all Beta angles of offset curves and single curve constraints in each object respectively.
- Rot. Offset: Only rotate the offset curve for each object in a curve library.
- Rot. Obj.: Only rotate the Beta angles of the single curve constraint.

Bounding Box - All: 선택된 모든 객체를 감싸는 최소 크기의 박스 형태가 Preview 됩니다.The shape of The preview that the smallest one box that wraps all selected objects is Previewedwill be displayed.

Bounding Box - Each: 선택된 객체를 각각 감싸는 최소 크기의 박스 형태가 Preview 됩니다.The shape of the smallest box that wraps each selected object is PreviewedThe preview that the smallest several boxes wrap each selected object will be displayed.

Original Model : 원본 형상과 동일한 Preview가 표출됩니다.Preview The preview the same as the original shape is will be displayed.
