Here, a complex shape forms the top of the model, whilst the second sketch is a simple circle.

By adding many sketches, it is possible to model the cross-section of a complex aircraft fuselage, and by altering individual sketches the model can be modified and re-lofted until the final shape is produced.

This activity highlights the kinematic capabilities of Pro/DESKTOP. By clicking on the hyperlink below Pro/DESKTOP will be loaded with the model shown on the left activated.

By using the select parts tool you can select the flap, and by keeping the mouse button depressed move the flap up and down. This is a simple example illustrating how parts can be combined using assembly constraints to produce models which animate.

The wing was modelled as described in the previous sections.

A rectangular sketch was then drawn on the was then drawn on the wing to represent the size of the flap. The wing was then saved.

Two extrusions then produce the assembly. The first uses the subtract material option which creates the wing with the cutout. The wing is then saved under a different name. The second extrusion uses the intersect material option which removes the wing and leaves the flap.
