Activity 1.4.2 Making Sketches in CAD, we used the sketch tools to place our names on a sketch plane that was located tangent to the outside surface of a wrist band model. Emboss is a function that allows the user to raise a design from a surface, or carve a design into a surface. This function requires a feature and a profile, such as the wrist band and text. We used the emboss function to project the text down onto the surface of the wrist band, and extruded the letters a distance of .02 inch.
. In Activity 1.4.2 Making Sketches in CAD, we used the sketch tools to insert a JPG graphic onto a sketch plane that was located tangent to the outside surface of a water bottle model. Decal is a function that allows the user to place an image onto a model surface. This function requires a feature and sketch, such as the water bottle and the logo graphic pictured above. Graphics must be either JPG or BMP formats. We used the decal function to wrap the image around the surface of the water bottle.
The coil function allows the user to extrude a closed profile along a helical path and around an existing axis. The axis may be an existing edge, a sketched line, or a work axis. We used the coil function to turn the existing circle into a spring form by coiling it around the Y axis of the Cartesian coordinate grid. The Y axis must be selected from the origin folder in the browser bar. The spring will have a height of 6 inches and the circle will revolve around the Y axis a total of five times.
A rib is a relatively thin flat member that acts as a brace support. It is also referred to as a web. The rib function allows the user to place such a support between two intersecting surfaces. A line profile has been created on a work plane that exists midway through the object. We used the rib function to turn this line profile into a .125 inch support web between the two perpendicular surfaces.
. The rectangular pattern function allows the user to make copies of an existing feature in one direction, or two directions simultaneously. Existing edges or the axes of the Cartesian coordinate grid must be selected to identify the desired direction(s). We used the rectangular pattern to copy the existing cylindrical extrusion six times in the horizontal direction and four times in the vertical direction.
Some patterned features follow contoured paths. We used the rectangular pattern function to copy the existing rectangular extrusions 13 times along the curved path of the base feature.
. The sweep function allows the user to extrude a closed profile along a path. The path may be open or closed. The profile and the path must exist as two separate sketches. We used the sweep function to extrude the circle along the existing path to create the form of a paper clip.
