\n\nWhen you have completed this module, you will be able to:\n
    \n \t
  1. \u00a0Describe and apply the SOLIDEDIT command and the Shell option to create a hollow cavity, with a specified wall thickness, in a solid model.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n

    Shell<\/h1>\nA shell <\/em><\/span>is preformed when material is removed from the interior of a solid model leaving a hollow cavity with a specify wall thickness. This is done using the Shell option in the SOLIDEDIT command. See Figures 29-1, 29-2, and 29-3.\n\nAfter entering the Shell option, you can specify one or more faces to be removed. That leaves the remaining faces for the shell walls. If no faces are specified for removal, the shell creates a hollow model. The thickness of the shell wall can also specified.\n\n[caption id=\"attachment_1194\" align=\"aligncenter\" width=\"247\"]\"\" Figure 29-1 Solid Before Shell[\/caption]\n\n[caption id=\"attachment_1194\" align=\"aligncenter\" width=\"225\"]\"\" Figure 29-2

    WORK ALONG: Shelling<\/h1>\n

    Step 1<\/h2>\nUsing the NEW command, start a new drawing using template: 3D Layout English<\/span>.\n

    Step 2<\/h2>\nSave the drawing with the name: AutoCAD 3D Workalong 29-1<\/span>.\n

    Step 3<\/h2>\nOn layer: Solid 3<\/span>, draw the two solid models using the multiview drawing as a reference. Start the bottom left corner of the cube at 0,0,0. (Figure Step 3A and 3B)\n\n[caption id=\"attachment_1194\" align=\"aligncenter\" width=\"600\"]\"\" Figure Step 3A

    AUTHOR'S COMMENTS: <\/strong>The Shell option is one of the trickiest options to use. The problem most student have is not knowing how to remove and add the faces back in. Watch the prompts as you select faces, it will tell you how many faces were removed so you know how many you have to add back in. If the commands does work the first time, undo the command try again. Keep doing this until you find it easy to do.<\/div>\n

    Step 6<\/h2>\nUsing what you just learned, click the Shell option again but this time, create a pipe with a 0.25 inch wall thickness. You will have to remove both ends of the pipe. See the command below.

    AUTHOR'S COMMENTS: <\/strong>As I said before, the Shell option is one of the trickiest options to use. In this step, you will have to orbit the model in the middle of the command to remove the face on the opposite end of the pipe.\n<\/strong><\/div>\n\n[caption id=\"attachment_1194\" align=\"aligncenter\" width=\"467\"]\"\" Figure Step 6B[\/caption]\n\n[caption id=\"attachment_1194\" align=\"aligncenter\" width=\"214\"]\"\" Figure Step 6C[\/caption]\n
