    Sweeps<\/h1>\nSweeps <\/em><\/span>are created by sweeping (moving) one or more profiles along a selected path. See Figure 22-1 and 22-2. The path<\/span> <\/em>can be an open or closed drawing object but must be one object. If the profile is a closed object, the sweep will create a solid. If the profile is an open object, the sweep will create a surface.\n\nSweeps are used to create models like pipes, tubbing, drain pipes, gasket grooves, and threads.\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"181\"]\"\" Figure 22-1

    Step 12<\/h2>\nUsing what you learned earlier, use the Properties windows and insure that object is a closed polyline.\n

    Step 13<\/h2>\nOffset the pline, towards the inside, at a distance of 0.05 inches. (Figure Step 13A and 13B)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"222\"]\"\" Figure Step 13A[\/caption]\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"234\"]\"\" Figure Step 13B[\/caption]\n

    Step 14<\/h2>\nSet layer: Solid 4<\/span> as the current layer and the current visual style to Realistic.\n

    Step 15<\/h2>\nUse the SWEEP command, as shown below, to sweep both profiles along the path in one command.

    AUTHOR'S COMMENTS:<\/strong> I created two solids, one inside the other, in one SWEEP command. You will see the reason for this in the following steps.<\/div>\n

    Step 15<\/h2>\nTurn layers: Path<\/span> and Profile<\/span> off.\n

    Step 16<\/h2>\nUsing what you learned earlier in the book, use the SUBTRACT command to subtract the inner solid from the outer solid. (Figure Step 16A, 16B, and 16C)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"275\"]\"\" Figure Step 16A[\/caption]\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"300\"]\"\" Figure Step 16B[\/caption]\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"210\"]\"\" Figure Step 16C[\/caption]\n\n
    AUTHOR'S COMMENTS:<\/strong> AutoCAD has an easier method, known as shelling, of creating a hollow solid without creating and subtracting an inner solid. Shelling will be taught in Module 29.<\/div>\n

    Step 17<\/h2>\nSave and close the drawing.\n

    WORK ALONG: Using the SWEEP Command - Part 2<\/h1>\n

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

    Step 2<\/h2>\nSave and name the drawing: AutoCAD 3D Workalong 22-2<\/span>. (Figure Step 2)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"500\"]\"\" Figure Step 2
    Dimensioned Drawing[\/caption]\n

    Step 3<\/h2>\nSet the current view to SE Isometric, the current UCS to World, the layer: Path<\/span> as the current layer, and the current visual style to 2D Wireframe.\n

    Step 4<\/h2>\nUsing Figure Step 2 as a reference, draw a closed pline as shown in the figure. (Figure Step 4)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"402\"]\"\" Figure Step 4[\/caption]\n

    Step 6<\/h2>\nUsing what you learned in the first workalong, fillet all of the corners, in one step, with a radius of 10. (Figure Step 6)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"400\"]\"\" Figure Step 6[\/caption]\n

    Step 7<\/h2>\nOffset the closed pline 5 mm towards the inside. (Figure Step 7)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"400\"]\"\" Figure Step 7[\/caption]\n

    Step 8<\/h2>\nSet the system variable ISOLINES to 24.\n
    AUTHOR'S COMMENTS: <\/strong>The ISOLINES system variable controls the smoothness of the curved faces. See Module 17.<\/div>\n

    Step 9<\/h2>\nSet layer: Solid 1<\/span> as the current layer. Extrude the outer pline 25 mm in the negative Z. (Figure Step 9)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"400\"]\"\" Figure Step 9[\/caption]\n

    Step 10<\/h2>\nFreeze layer: Solid Off<\/span>. Change the layer of the extruded outer solid that you created in Step 9 to layer: Solid Off<\/span>.\n
    AUTHOR'S COMMENTS:<\/strong> I changed the solid to layer Solid Off so that the solid does not get in the way of extruding the second solid.<\/div>\n

    Step 11<\/h2>\nExtrude the inner pline 20 mm in the negative Z. (Figure Step 11)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"400\"]\"\" Figure Step 11[\/caption]\n

    Step 12<\/h2>\nChange the layer of the first solid from layer: Solid Off<\/span> to layer: Solid 1<\/span>. Turn layer: Path<\/span> off. Your drawing should match the figure. (Figure Step 12)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"400\"]\"\" Figure Step 12[\/caption]\n

    Step 13<\/h2>\nChange the visual style to Realistic. (Figure Step 13)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"400\"]\"\" Figure Step 13[\/caption]\n\n
    AUTHOR'S COMMENTS:<\/strong> When the visual style is realistic, it is easier to select the solids when you are using the SUBTRACT command.<\/div>\n

    Step 14<\/h2>\nUsing the SUBTRACT command, subtract the inner solid from the outer solid. (Figure Step 14)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"400\"]\"\" Figure Step 14[\/caption]\n

    Step 15<\/h2>\nChange the layer of the solid on layer: Solid 1<\/span> to layer: Solid Off<\/span>. Turn layer: Path<\/span> on and set layer: Profile<\/span> as the current layer. Set the visual style to 2D wireframe. (Figure Step 15)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"400\"]\"\" Figure Step 15[\/caption]\n

    Step 16<\/h2>\nChange the current UCS to Right.\n

    Step 17<\/h2>\nDraw a closed pline 2.5 x 2.5 inches. Start it by snapping to endpoint of the inner pline. (Figure Step 17A, 17B, and 17C)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"277\"]\"\" Figure Step 17A[\/caption]\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"279\"]\"\" Figure Step 17B[\/caption]\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"378\"]\"\" Figure Step 17C[\/caption]\n\n
    AUTHOR'S COMMENTS: <\/strong>The pline you just drew is the profile for the sweep. It must connect to the path (inner pline).<\/div>\n

    Step 18<\/h2>\nSet layer: Solid 1<\/span> as the current layer.\n

    Step 19<\/h2>\nUsing the SWEEP command, sweep the 2.5 inch closed pline using the inner pline as the path. (Figure Step 19)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"400\"]\"\" Figure Step 19[\/caption]\n\n
    MUST KNOW:<\/strong> The SWEEP command requires at least one profile and a path. The path can be an open or closed object. The profile must be closed object to create a solid. The path must pierce or touch the profile.<\/div>\n

    Step 20<\/h2>\nChange the layer of the solid on layer: Solid Off<\/span> to layer: Solid 1<\/span>. Turn layers: Path<\/span> and Profile<\/span> off and change the visual style to Realistic. (Figure Step 20)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"400\"]\"\" Figure Step 20[\/caption]\n

    Step 21<\/h2>\nUsing the SUBTRACT command, subtract the solid that was created using the SWEEP command from the original solid. (Figure Step 21)\n\n[caption id=\"attachment_973\" align=\"aligncenter\" width=\"400\"]\"\" Figure Step 21[\/caption]\n

        Key Principles in Module 22<\/p>\n<\/header>\n

        \n
          \n
        1. Sweeps are created by sweeping (moving) one or more profiles along a selected path. The path can be an open or closed object but must be one object. If the profile is a closed object, the sweep will create a solid. If the profile is an open object, the sweep will create a surface.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n

          Step 1<\/h2>\n

          On layer: Profile<\/span>, draw the profile as a closed pline and on layer: Path<\/span>, draw the path as a single pline. (Figure Step 1A and 1B)<\/p>\n

          Step 2<\/h2>\n

          On layer: Solid 6<\/span>, create the solid using the SWEEP command.<\/p>\n

          Step 3<\/h2>\n

          Create the slots by first creating one and mirror it to create the opposite slot. Subtract them to complete the object.<\/p>\n
