This example demonstrates how to dimension A-part, which you drew in Example 1: A-part. Usually it is not meaningful to create the quantity of dimensions in this example. The exercises in this example enable you to practice creating dimensions using several different methods.

Setup

  1. Open the A-part to the Parts work area for dimensioning. For more information, see Opening Parts to Parts Work Area.

    The software opens the part to the work area (see below). The cursor snaps to the center point of a circle when you point to the work area. This is useful when creating dimensions.

Create the vertical main dimensions first

  1. Click Dimensions to display the Draw dimension object properties.

  2. Click Vertical dimension between two points . To measure the vertical dimension, do the following:

    1. Click the upper edge of circle 10 and the lower edge of circle 1. Drag the dimension to the necessary location, and then press ENTER or the Spacebar to accept the selection.

      If the dimension size is not suitable, type a new value in the Font Size box.

    2. Click the center point of circle 10 and the center point of circle 1. Drag the dimension to the necessary location and accept.

    3. Click the center point of circle 2 and the center point of circle 1. Drag the dimension to the necessary location and accept.

    4. Click the center point of circle 2 and the center point of circle 9. Drag the dimension to the desired location and accept.

Create the horizontal main dimensions

  1. Click Horizontal dimension between two points .

  2. Click the left edge of circle 1 and the right edge of circle 2. Drag the dimension to the necessary location and accept.

  3. Click the center point of circle 1 and the center point of circle 2. Drag the dimension to the necessary location and accept.

  4. Click the center point of circle 2 and the center point of circle 9. Drag the dimension to the necessary location and accept.

  5. Click the center point of circle 10 and the center point of circle 2. Drag the dimension to the necessary location and accept.

Create the dimensions for the arcs

  1. Click Length of an arc or a fillet .

  2. Create dimensions for the remaining arcs for circle 1, circle 2, and circle 10.

  3. Create dimensions for the fillets for the intersections of line 13, line 14, and line 15.

  4. Click the arc, and then drag the dimension to the necessary location and accept.

Create the dimension for circle 9

  1. Click Radius of an arc, a circle, or a fillet . Alternatively, click Diameter of an arc, a circle, or a fillet .

  2. Click circle 9, and then drag the dimension to the necessary location and accept.

Draw aid lines

Aid lines enable you to create dimensions for the perpendicular distances between lines.

  1. Click Line .

  2. To draw an aid line between the center points of circle 1 and circle 2, do the following:

    1. Snap to the center point of circle 1, and draw a line to the center point of circle 2 using snap. Accept the aid line.

      For more information on snapping to elements, see Snap in View Bar.

    2. Draw a perpendicular aid line between the following lines, and accept after each line:

      • Between line 11 and line 13

      • Between line 12 and line 15

      • Between line 6 and the aid line between line 12 and line 15

      • Between the aid line and line 15

    3. Snap to a line, and then click the line to insert the start point for the aid line.

    4. Click Perpendicular Add relation_Perpendicular ICON from the Add relation menu, and click the other line.

    5. Draw the aid line between the two lines in steps c and d (the lines snap into position), and accept.

  3. To create dimensions for perpendicular distances, do the following:

    1. Click Dimension between two points .

    2. Click the start point and the end point of the aid line.

    3. Move the dimension to the necessary location, and accept.

    4. Repeat these steps for each aid line.

  4. Trim or remove the aid lines except the aid line between circle 1 and circle 2.

  5. Change the aid line between circle 1 and circle 2 because it is not to be cut. Do the following:

    1. Activate the aid line to display the parameters in the State Manager.

    2. Change the Machining mode to Info.

  6. Click Dimension between two points and do the following:

    1. Create a dimension between the center point of circle 1 and the intersection of line 6 and line 7.

    2. Create a dimension for the distance between the center point of circle 2 and the intersection of line 6 and line 8.

  7. Save the part. You can print it if necessary.
