    WORK ALONG: Drawing a Solid Model with Arcs and Rectangles<\/h1>\r\n

    Step 1<\/h2>\r\nCheck the current project and if necessary, set it to Inventor Course.\r\n

    Step 2<\/h2>\r\nUsing the NEW command, start a new part file using the template: English-Modules Part (in).ipt<\/span>.\r\n

    Step 3<\/h2>\r\nSave the file with the name: Inventor Workalong 18-1<\/span>. (Figure Step 3A, 3B, 3C, and 3D)\r\n\r\n[caption id=\"attachment_1378\" align=\"aligncenter\" width=\"500\"]\"\"<\/a> Figure Step 3A

    3D Model - Rotated View [Click to see image full size][\/caption]\r\n

    Step 4<\/h2>\r\nStart the Base sketch on the Front or XZ plane. Project the Center Point onto the sketch.\r\n

    Step 5<\/h2>\r\nDraw the four outside lines of the Base sketch. (Figure Step 5)\r\n\r\n[caption id=\"attachment_1382\" align=\"aligncenter\" width=\"349\"]\"\" Figure Step 5[\/caption]\r\n

    Step 6<\/h2>\r\nOffset all four lines as shown in the figure. (Figure Step 6)\r\n\r\n[caption id=\"attachment_1386\" align=\"aligncenter\" width=\"362\"]\"\" Figure Step 6[\/caption]\r\n

    Step 7<\/h2>\r\nTrim and dimension the sketch ensuring that it is totally constrained. (Figure Step 7)\r\n\r\n[caption id=\"attachment_1383\" align=\"aligncenter\" width=\"477\"]\"\" Figure Step 7[\/caption]\r\n

    Step 8<\/h2>\r\nPress F6 to change the view to the Home view. All of the lines in the sketch should appear purple. Extrude the sketch. (Figure Step 8)\r\n\r\n[caption id=\"attachment_1384\" align=\"aligncenter\" width=\"300\"]\"\" Figure Step 8[\/caption]\r\n

    Sketching Without the Grid<\/h2>\r\nUp to this point in the Inventor book, the grid display has been enabled in Sketch mode. To the more experienced operator, grid display can be disabled in Sketch mode. On some sketches, it is sometimes easier to draw without the grid getting in the way.\r\n

    Step 9<\/h2>\r\nStart a new sketch on the right side face as shown in the figure. (Figure Step 9)\r\n\r\n[caption id=\"attachment_1385\" align=\"aligncenter\" width=\"260\"]\"\" Figure Step 9[\/caption]\r\n

    Step 10<\/h2>\r\nUsing what you already learned, open the Application Options dialogue box.\r\n

    Step 11<\/h2>\r\nEnable the Sketch tab.\r\n

    Step 12<\/h2>\r\nIn the Display area, disable Grid Lines. (Figure Step 12)\r\n\r\n[caption id=\"attachment_1387\" align=\"aligncenter\" width=\"400\"]\"\" Figure Step 12[\/caption]\r\n\r\n
    AUTHOR'S COMMENTS:<\/strong> Disabling the grid display in a sketch can help when drawing some sketches.<\/div>\r\n

    Step 13<\/h2>\r\nDraw a construction line 0.5 inches below the top edge and dimension it. Ensure that it is fully constrained. (Figure Step 13)\r\n\r\n[caption id=\"attachment_1388\" align=\"aligncenter\" width=\"300\"]\"\"<\/a> Figure Step 13 [Click to see image full size][\/caption]\r\n
    AUTHOR'S COMMENTS: <\/strong>Do not offset an edge. Draw the line, using the LINE command, constrain it perpendicular to one of the edges.<\/div>\r\n

    Step 14<\/h2>\r\nClick the THREE POINT ARC command. Snap the first point to one end of the construction line, snap the second point to the other end of the construction line. For the third point, snap it to the midpoint of the top edge. (Figure Step 14A, 14B, and 14C)\r\n\r\n[caption id=\"attachment_1389\" align=\"aligncenter\" width=\"288\"]\"\" Figure Step 14A[\/caption]\r\n\r\n[caption id=\"attachment_1390\" align=\"aligncenter\" width=\"288\"]\"\" Figure Step 14B[\/caption]\r\n\r\n[caption id=\"attachment_1391\" align=\"aligncenter\" width=\"268\"]\"\" Figure Step 14C[\/caption]\r\n

    Step 15<\/h2>\r\nUsing the CREATE CONSTRAIN command, apply the Tangent constraint to the arc and the top edge. This should fully constrain the sketch. (Figure Step 15)\r\n\r\n[caption id=\"attachment_1392\" align=\"aligncenter\" width=\"300\"]\"\"<\/a> Figure Step 15 [Click to see image full size][\/caption]\r\n

    Step 16<\/h2>\r\nExtrude the sketch.

    Step 17<\/h2>\r\nUsing what you just learned, start a new sketch on the top of the model. On it, draw three construction lines and a three point arc. Ensure that the sketch is fully constrained. Extrude the sketch. (Figure Step 17A and 17B)\r\n\r\n[caption id=\"attachment_1395\" align=\"aligncenter\" width=\"300\"]\"\"<\/a> Figure 17A [Click to see image full size][\/caption]\r\n\r\n[caption id=\"attachment_1396\" align=\"aligncenter\" width=\"300\"]\"\"<\/a> Figure 17B[\/caption]\r\n

    Step 18<\/h2>\r\nStart a new sketch on the lower plane. (Figure Step 18)\r\n\r\n[caption id=\"attachment_1397\" align=\"aligncenter\" width=\"415\"]\"\" Figure Step 18[\/caption]\r\n\r\n
    AUTHOR'S COMMENTS: <\/strong>I have shown the new sketch with the grid displayed only to help you visualize what plane the sketch is on.<\/div>\r\n

    Step 19<\/h2>\r\nOn the sketch, using the TWO POINT RECTANGLE command, draw a rectangle by selecting two opposite corners. Guess at the location and size. (Figure Step 19)\r\n\r\n[caption id=\"attachment_1398\" align=\"aligncenter\" width=\"300\"]\"\"<\/a> Figure Step 19 [Click to see image full size][\/caption]\r\n

    Step 20<\/h2>\r\nInsert four dimensions, one from each edge. Check to ensure that the sketch is fully constrained and extrude it. (Figure Step 20A and 20B)\r\n\r\n[caption id=\"attachment_1399\" align=\"aligncenter\" width=\"300\"]\"\" Figure Step 20A [Click to see image full size][\/caption]\r\n\r\n[caption id=\"attachment_1400\" align=\"aligncenter\" width=\"300\"]\"\" Figure Step 20B[\/caption]\r\n

    Step 21<\/h2>\r\nStart a new sketch on the back plane and place a construction line as shown in the figure. Do not offset the edge. Ensure that you constrain the line perpendicular to the bottom or top edge. You can guess at the start point and the length of the line. (Figure Step 21)\r\n\r\n[caption id=\"attachment_1401\" align=\"aligncenter\" width=\"300\"]\"\" Figure Step 21 [Click to see image full size][\/caption]\r\n

    Step 22<\/h2>\r\nChange the property of the line to a construction line. Insert one circle at the each end of the line. Snap to the end of the line to locate the centre of the circles. (Figure Step 22)\r\n\r\n[caption id=\"attachment_1402\" align=\"aligncenter\" width=\"274\"]\"\" Figure Step 22[\/caption]\r\n

    Step 23<\/h2>\r\nUsing what you learned already, dimension one of the circles and then create an Equal constraint for the other one. Draw lines on either side of the circle. Ensure that you snap the end of the lines onto the circles. Constrain the lines to the circle with the Tangent constraint. Trim the circles. (Figure Step 23A, 23B, and 23C)\r\n\r\n[caption id=\"attachment_1403\" align=\"aligncenter\" width=\"247\"]\"\" Figure Step 23A[\/caption]\r\n\r\n[caption id=\"attachment_1404\" align=\"aligncenter\" width=\"270\"]\"\" Figure Step 23B[\/caption]\r\n\r\n[caption id=\"attachment_1405\" align=\"aligncenter\" width=\"175\"]\"\" Figure Step 23C[\/caption]\r\n

    Step 24<\/h2>\r\nDraw a construction line from the end of the construction line at the top circle, constraining it perpendicular to one of the vertical lines. Draw it approximately 1 inch long. (Figure Step 24)\r\n\r\n[caption id=\"attachment_1406\" align=\"aligncenter\" width=\"294\"]\"\" Figure Step 24[\/caption]\r\n

    Step 25<\/h2>\r\nClick the COPY command and select the two lines and the arcs as shown in the figure. Ensure that the Select icon is enabled. (Figure Step 25)\r\n\r\n[caption id=\"attachment_1407\" align=\"aligncenter\" width=\"615\"]\"\"<\/a> Figure Step 25 [Click to see image full size][\/caption]\r\n

    Step 26<\/h2>\r\nEnable the From icon and select the end of the construction line for the From location. (Figure Step 26)\r\n\r\n[caption id=\"attachment_1408\" align=\"aligncenter\" width=\"615\"]\"\"<\/a> Figure Step 26 [Click to see image full size][\/caption]\r\n

    Step 27<\/h2>\r\nEnable the To icon and select the other end of the construction line for the To location. (Figure Step 27)\r\n\r\n[caption id=\"attachment_1409\" align=\"aligncenter\" width=\"615\"]\"\"<\/a> Figure Step 27[\/caption]\r\n

    Step 28<\/h2>\r\nIf you get the warning message, click Yes.\r\n

    Step 29<\/h2>\r\nDimension the sketch until it is fully constrained. (Figure Step 29)\r\n\r\n[caption id=\"attachment_1410\" align=\"aligncenter\" width=\"300\"]\"\"<\/a> Figure Step 29 [Click to see image full size][\/caption]\r\n

    Step 30<\/h2>\r\nReturn to Model mode and extrude the slots. Extrude them 0.25 inches deep. (Figure Step 30)\r\n\r\n[caption id=\"attachment_1411\" align=\"aligncenter\" width=\"615\"]\"\"<\/a> Figure Step 30 [Click to see image full size][\/caption]\r\n

    Step 31<\/h2>\r\nStart a new sketch on the bottom of the extruded slots. Enter the OFFSET command and right-click one of the arcs. In the Right-click menu, enable Loop Select. Select the other arc and the lines to complete the loop. (Figure Step 31A and 31B)\r\n\r\n[caption id=\"attachment_1412\" align=\"aligncenter\" width=\"256\"]\"\" Figure Step 31A[\/caption]\r\n\r\n[caption id=\"attachment_1413\" align=\"aligncenter\" width=\"129\"]\"\" Figure Step 31B[\/caption]\r\n

    Step 32<\/h2>\r\nOffset the slot towards the inside. Guess at the offset distance. (Figure Step 32)\r\n\r\n[caption id=\"attachment_1414\" align=\"aligncenter\" width=\"121\"]\"\" Figure Step 32[\/caption]\r\n

    Step 33<\/h2>\r\nDimension the offset. (Figure Step 33)\r\n\r\n[caption id=\"attachment_1415\" align=\"aligncenter\" width=\"130\"]\"\" Figure Step 33[\/caption]\r\n

    Step 34<\/h2>\r\nExtrude the slot To Next. (Figure Step 34)\r\n\r\n[caption id=\"attachment_1416\" align=\"aligncenter\" width=\"304\"]\"\" Figure Step 34[\/caption]\r\n

    Step 35<\/h2>\r\nRedo Step 31 to 34 on the other slot to complete the solid model.\r\n

        Sketching Without the Grid<\/h2>\n

        Up to this point in the Inventor book, the grid display has been enabled in Sketch mode. To the more experienced operator, grid display can be disabled in Sketch mode. On some sketches, it is sometimes easier to draw without the grid getting in the way.<\/p>\n

        Step 9<\/h2>\n

        Start a new sketch on the right side face as shown in the figure. (Figure Step 9)<\/p>\n
