CST2013: Loft Curves Mode

Modeling: CurvesCurve ToolsLoft Curves

In this mode, you may interactively select profile and path curves for the generation of a free-form surface.

Please note that all profiles and the path must belong to different curves. To move items from one curve onto another, use the Curve Change Curve operation.

The generated free form surface passes through all profile curves. If a path curve is specified, the intersection vector between each profile cross-section and the path curve will be calculated. These directions will then be applied to the profile curves to determine the tangential direction of the generated free form surface at the given profiles.

When you first enter the mode, you will be asked to double-click on a curve to select the first profile curve for lofting. By moving the mouse across the screen, all pickable curves at the mouse’s location will automatically be highlighted. As soon as a curve is highlighted, you may double-click on it to make your selection.

You may change the view at any time by using the standard view changing options.

After the first profile curve has been selected, the next profile needs to be selected in the same manner. This step-by-step selection of profile curves may be ended by pressing the RETURN key. Please note that at least two profile curves must be specified.

When the selection of profile curves is finished, the path curve may optionally be specified. This stage may be skipped by pressing the RETURN key.

After the curves have been selected, a loft curves dialog box appears where you may specify a name , a component and a material for the new shape.

You may terminate the mode at any time by pressing the ESC key.
