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

\r\n\r\nWhen you have completed this module, you will be able to:\r\n
    \r\n \t
  1. Describe the geometry of an arc and how arcs are drawn in Inventor.<\/li>\r\n \t
  2. Describe how to snap to midpoints of lines.<\/li>\r\n \t
  3. Apply the CENTER POINT ARC command to draw arcs in 2D sketches.<\/li>\r\n<\/ol>\r\n<\/div>\r\n<\/div>\r\n

    Drawing Arcs<\/h1>\r\nThere are three commands available to draw arcs in Inventor. In this module, drawing arcs using the CENTER POINT ARC command will be taught. Similar to the CIRCLE command, the CENTER POINT ARC command also requires you to select the centre point and the radius. Drawing arcs additionally require you to locate the start point and end point or the arc. Arcs can be constructed clockwise or counterclockwise.\r\n

    Geometry Lesson: Arcs<\/h1>\r\nAn ARC<\/span> <\/em>is defined as an open curve in which all points are the same distance from its centre point. Study the drawings in Figure 13-1 and 13-2.for a description of the geometry of an arc.\r\n\r\n[caption id=\"attachment_1117\" align=\"aligncenter\" width=\"500\"]\"\" Figure 13-1

        Key Principles in Module 13<\/p>\n<\/header>\n

        \n
          \n
        1. There are three commands available to draw arcs in Inventor. Similar to the CIRCLE command, the CENTER POINT ARC command also requires you to select the location of the centre point and the radius. Drawing arcs additionally requires you to locate the start point and end point or the arc. Arcs can be constructed clockwise or counterclockwise.<\/li>\n
        2. When drawing arcs, do your best to tie the centre point, the start point, and the end point to existing geometry. This will decrease the number of dimensions that are required to constrain the arc.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n
