This is a limitation of the OpenCASCADE kernel that FreeCAD uses. Sketches containing B-Splines often cannot be properly tapered.This is done to facilitate the design of molds and molded parts. Note that inner structures receive the opposite taper angle. This option is only available if Type is either Dimension or Two dimensions.

A positive angle means the outer pad border gets wider. Tapers the pad in the extrusion direction by the given angle. Tick the checkbox to extrude half of the given length to either side of the sketch or plane. introduced in version 0.20 Symmetric to plane If checked, the pad length is measured along the sketch normal, otherwise along the custom direction. introduced in version 0.20 Length along sketch normal In case the pad uses a Custom direction, it can be changed. If checked, the pad direction will be shown. Custom direction The sketch is extruded along a direction that can be specified via vector values.When this is method selected, you can click on any edge in the 3D model and it becomes the direction vector for the extrusion. The sketch is extruded along an edge of the 3D model. If you have selected several sketches or faces to be extruded, the normal of the first one will be used. Sketch normal The sketch or face is extruded along its normal.You can select the direction of the extrusion: This option is only available when Type is either To last, To first or Up to face. Offset from face at which the pad will end. This option is only available when Type is either Dimension or Two dimensions. Multiple units can be used independently of the user's units preferences (m, cm, mm, nm, ft or ', in or '). The directions can be switched by ticking the Reversed option.ĭefines the length of the pad. This allows to enter a second length in which the pad should extend in the opposite direction (into the support). The pad will extrude up to a face in the model that can be chosen by clicking on it. If there is no support, an error message will appear. The pad will extrude up to the first face of the support in the extrusion direction. The pad will extrude up to the last face of the support in the extrusion direction. With the option Symmetric to plane the pad will extend half of the given length to either side of the plane. This can be changed by specifying another Direction. Extrusions occur by default normal to the defining sketch plane. The default direction for extrusion is away (outside of) the support, but it can be changed by ticking the Reversed option. Type offers five different ways of specifying the length to which the pad will be extruded:Įnter a numeric value for the length of the pad.
