Thin Wall Sweep

An additional mode for creating a thin-walled feature allows you to change the extrusion result. The result is a body similar to the one created using the Shell operation. This mode is available only when extruding planar contours.

When setting the thickness, there are several options in the drop-down list:

No – the extrusion result remains unchanged (it is used to obtain a surface body based on a surface contour; for a wire contour, the result is the same as the extrusion result without turning on the thin-walled element mode);

Source profile                                        Surface body

With giving the required thickness to the side walls in various ways (inside, outside, symmetrically, with different wall thicknesses inside and outside the original face), a thin-walled solid body is created from a surface body by adding thickness to the walls.

New faces in a thin-walled body are formed by extruding a contour equidistant from the original extrusion contour. The shape of the faces depends on the way gaps are processed when creating an equidistant contour:

By Curve – a continuation of the curves forming the source contour is created.

By Line – straight lines are created from the break points, tangent to the contour lines at the break points.

Round – rounding is created between the end points of neighboring segments of the created contour.
