Learning Outcomes<\/p>\n\n<\/header>\n

\n\nWhen you have completed this module, you will be able to:\n
    \n \t
  1. Apply the SLICE command to cut solid models into two individual solids.<\/li>\n \t
  2. Apply the SECTION command to create 2D cross sectional regions through solid models.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n

    Sectioning<\/h1>\nThe SLICE and SECTION commands are used to create cross sections from solid models. They can be very useful commands and save you drawing time.\n\nThe SLICE command, see Figure 20-1A and 20-1B, cuts a solid model into two individual solids.\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"284\"]\"\" Figure 20-1A
    Before Slice[\/caption]\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"358\"]\"\" Figure 20-1B
    After Slice[\/caption]\n\nThe SECTION command, see Figure 20-2, creates a two dimensional region along a selected cutting plane. The region can then be relocated to produce a cross section view in 2D and used as a detail drawing. See Figure 20-3 and 20-4.\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"296\"]\"\" Figure 20-2

    WORK ALONG: Sectioning Solid Models<\/h1>\n

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

    Step 2<\/h2>\nSave and name the drawing: AutoCAD 3D Workalong 20-1<\/span>.\n

    Step 3<\/h2>\nUsing the figures as a reference, draw the closed plines on layer: Pline<\/span>. (Figure Step 3)\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"500\"]\"\" Figure Step 3[\/caption]\n

    Step 4<\/h2>\nDraw the solid model on layer: Solid 7<\/span>. (Figure Step 4)\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"296\"]\"\" Figure Step 4[\/caption]\n

    Step 5<\/h2>\nTurn layer: Pline<\/span> off. Set the current UCS set to World and make a copy of the solid model 12 inches along the X axis. (Figure Step 5)\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"411\"]\"\" Figure Step 5[\/caption]\n

    Step 6<\/h2>\nSet the current visual style to 2D Wireframe. On the original solid model, enter the SLICE command, as shown below, to slice it into two parts. (Figure Step 6A and 6B)\n\nCommand: SLICE<\/strong>\n\nSelect objects: 1 found\n\n(Select the solid model.)<\/em><\/span>\n\nSelect objects:\n\n(Press Enter.)<\/em><\/span>\n\nSpecify first point on slicing plane by [Object\/Zaxis\/View\/XY\/YZ\/ZX\/3points] <3points>: (mid) <\/em><\/span>P1<\/strong>\n\nSpecify second point on plane: (mid) <\/em><\/span>P2<\/strong>\n\nSpecify third point on plane: (mid) <\/em><\/span>P3<\/strong>\n\n(Ensure you snap to the midpoint of each edge. If you drew an imaginary line from P1 to P2 to P3 and back to P1, it would form a cutting plane. You will have to orbit the model to do this.)<\/em><\/span>\n\nSpecify a point on desired side of the plane or [keep Both sides]: B<\/strong>\n\n(Enter B to retain both sides of the slice.)<\/em><\/span>\n\nCommand:\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"278\"]\"\" Figure Step 6A[\/caption]\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"247\"]\"\" Figure Step 6B[\/caption]\n

    Step 7<\/h2>\nChange the current visual style to Realistic. (Figure Step 7)\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"296\"]\"\" Figure Step 7[\/caption]\n

    Step 8<\/h2>\nUsing the MOVE command, move the right half away from the left half. The distance you move it is not important. (Figure Step 8)\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"381\"]\"\" Figure Step 8[\/caption]\n

    Step 9<\/h2>\nYour model should now appear similar to the figure. (Figure Step 9)\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"353\"]\"\" Figure Step 9[\/caption]\n

    Step 10<\/h2>\nSet the current visual style to 2D Wireframe and set layer: Hatch<\/span> as the current layer. Using the copied solid, enter the SECTION command, as shown below, to create a cross section. (Figure Step 10A and 10B)\n\nCommand: SECTION<\/strong>\n\nSelect objects: 1 found\n\n(Select the solid.)<\/em><\/span>\n\nSelect objects:\n\nSpecify first point on Section plane by\n\n[Obj\/Zaxis\/View\/XY\/YZ\/ZX\/3points] <3points>: (mid) <\/em><\/span>P4<\/strong>\n\nSpecify second point on plane: (mid) <\/em><\/span>P5<\/strong>\n\nSpecify third point on plane: (mid) <\/em><\/span>P6<\/strong>\n\nCommand:\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"257\"]\"\" Figure Step 10A[\/caption]\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"256\"]\"\" Figure Step 10B[\/caption]\n\n
    AUTHOR'S COMMENTS: <\/strong>You will have to orbit the model a bit to select the correct lines.\n<\/strong><\/div>\n
    AUTHOR'S COMMENTS: <\/strong>The SECTION command creates a 2D region.\n<\/strong><\/div>\n

    Step 11<\/h2>\nUsing the MOVE command move the region, that you just created, outside of the solid. The distance you move it is not important. (Figure Step 11)\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"345\"]\"\" Figure Step 11[\/caption]\n

    Step 12<\/h2>\nExplode the region to convert it to lines. On layer: Hatch<\/span>, add the lines to complete the cross section view as shown the figure. (Figure Step 12)\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"191\"]\"\" Figure Step 12[\/caption]\n

    Step 13<\/h2>\nSet the current UCS to Front, the visual style to 2D Wireframe and set layer: Hatch<\/span> as the current layer. Using the HATCH command, insert the hatch pattern ANS131. (Figure Step 13)\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"190\"]\"\" Figure Step 13[\/caption]\n\n
    AUTHOR'S COMMENTS: <\/strong>Since HATCH is a 2D command, you must have the UCS located on the Front and the visual style set to 2D Wireframe.\n<\/strong><\/div>\n

    Step 14<\/h2>\nYour drawing should now appear similar to the figure. (Figure Step 14)\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"405\"]\"\" Figure Step 14[\/caption]\n

    Step 15<\/h2>\nMove the original solid back together using osnap to locate it exactly. Use the UNION command to join the two halves into one solid model. Using the Properties window, check to ensure that you only have one solid object. (Figure Step 15)\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"212\"]\"\" Figure Step 15[\/caption]\n

    Step 16<\/h2>\nSet the current UCS to Right<\/span> and the visual style to 2D Wireframe. (Figure Step 16)\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"234\"]\"\" Figure Step 16[\/caption]\n

    Step 17<\/h2>\nEnter the SLICE command, as shown below, to cut the solid through the centre of the hole on the XY plane. (Figure Step 17)\n\nCommand: SLICE<\/strong>\n\nSelect objects: 1 found\n\n(Select the solid.)<\/em><\/span>\n\nSelect objects: Specify first point on slicing plane by\n\n[Object\/Zaxis\/View\/XY\/YZ\/ZX\/3points] <3points>: XY<\/strong>\n\n(The XY plane is selected to be the cutting plane.

The solid will be sliced through centre of the circle, parallel to XY plane.)<\/em><\/span>\n\nSpecify a point on desired side of the plane or [keep Both sides]: P8<\/strong><\/span>\n\n(Only the left side is kept.)<\/em><\/span>\n\nCommand:\n\n[caption id=\"attachment_904\" align=\"aligncenter\" width=\"267\"]\"\" Figure Step 17[\/caption]\n

        1. The SLICE command cuts a solid model into two individual solids.<\/li>\n
        2. The SECTION command creates a two dimensional region along a selected cutting plane. The region can then be relocated to produce a cross section view in 2D and used as a detail drawing.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n
