Shell
Shell
Adding a Shell feature to a part provides an easy way to remove volume from a solid by offsetting faces either to the inside, the outside or to both sides of the part. When we first start the shelling process, by default, all faces are chosen and a uniform thickness is applied. It is possible to control the wall thickness on each face individually and to exclude faces to create parts with open sides. In this tutorial, we will explore the 3 types of shelling and exclude a face to create a casting.
Shell Part 1
Shell Part 1
Create a 3" diameter circle and extrude it .1"
Start a 2D-Sketch on the top of the cylinder, use project geometery to trace the top surface, and the offset tool to create a .25" smaller circle.
Use the line tool to bisect the inner circle then use the trim tool to remove the bottom half of the inner circle.
Finish Sketch.
Use the Revolve tool to revolve the semi circle 180 degrees, click OK.
Use the shell tool to create a shell of the object you made.
You must click the bottom face of the object to remove it while making the initial shell.
Save as "Shell Part 1"
Shell Part 2
Shell Part 2
Start a new 2D sketch and create a 9" diameter circle.
Finish Sketch.
Use an Offset Plane to create a 4" diameter circle 7" above sketch 1.
Finish sketch.
Use the Loft tool to connect the two sketches.
Hide the visibility of the work plane after you loft.
Use the Shell tool to create a .1" shell - remove top and bottom faces.
