The contour can be created the same way as the Shape Primitive with the exception that this

contour does not have to be closed and there is an extra Scale parameter adjusting its size

compared to the path used for the extrusion.

The path is yet another modified Cardinal-spline based shape, drawn the same way as the

contour of the 3D Model or the Shape Primitive. The path can be closed or unclosed, and you can

also check if you want the end caps created. You can set three materials to define the final look

of your model. One material for the extrusion itself, and two for the two end caps.

Other settings are:

– Smooth normals: check if you want a less segmented, smoother look.

– Rounded joins: this setting influences the way the segments of the model will connect at

specific points of the path.

– Tx, Ty, R, Sx, Sy: You can transform the contour shape at every point of the path. The

transform is 2D, and Rotation is only possible along the Z axis. By adjusting just the size

of the contour (Sx, Sy) at the path points, you can easily create a beveled extrusion of the

contour.

– PathStart, PathEnd: These are the only animatable parameters of the extrusion. It

defines the number of segments that will actually be drawn on screen. If PathStart is 0

and PathEnd is 1, all segments are drawn, if PathStart is 0.5 and PathEnd is 1 then only

the second half of the model is drawn. Of course, the greater the number of segments of

the model, influenced by the subdivision setting, the more precise is the animation you

can create by setting keyframes for these parameters.

– Auto: If checked, any change in any of the settings will automatically update the final

model. If you use complex and more detailed contours or paths this can result in a much
