The coordinate pairs are treated as ( x, y) values in the % Coordinate Matrix Example: % Square Cross-Section with Center at and Side Length 2 The Revolved Solid block sweeps the L shape about an axis lying on the cross-section plane to obtain the final peg geometry. The figure shows a cylindrical peg, a Revolved Solid whose cross-section, like the angle beam, consists of two thin rectangles arranged in an L shape. Revolved examples include cones, domes, pistons, gear shafts, and pipe bends. As with extruded shapes, the cross-section can have an arbitrary outline with or without holes. The sweep can span a full revolution or a lesser angle between 0 and 360 degrees. Use the Revolved Solid block to make an angular sweep of a cross-section about an axis that lies on the same plane as the cross-section. The cross-section outline is fixed by the number of sides of the polygon and it cannot contain holes. This shape is a simpler version of General extrusion and is suited only for solids whose cross-sections are regular polygons-those with sides of the same length. The Extruded Solid block provides a second extrusion shape, named Regular extrusion. The Extruded Solid block sweeps the L shape linearly out of the cross-section plane to obtain the final beam geometry.Ī Note on Extruded Solid Shapes. The figure shows an angle beam, a general extrusion whose cross-section consists of two thin rectangles arranged in an L shape. General extrusion examples include straight beams, plates, spars, struts, and rods. The cross-section can have an arbitrary outline and one or more hollow sections-though the rules for specifying cross-sections differ slightly when holes are present. The sweep spans the length specified in the Extruded Solid block dialog box. What is the Extruded Solid Block?Ī general extrusion is a linear sweep of a custom cross-section along an axis that is normal to the cross-section plane. The Extruded Solid block can either be a General extrusion or a Regular extrusion. Use them when modeling solids that have arbitrary yet constant cross-sections along or about an axis. Modeling Extrusions and Revolutions Extrusions and Revolutionsįor solids with custom cross-sections, the Extruded Solid and Revolved Solid blocks enable you to create truer solid representations than simpler shapes such as Brick Solid, Cylindrical Solid, and Spherical Solid often allow.
