2. Choose the OK button from this dialog box; a new SOLIDWORKS part document is started.
3. Choose the Sketch button from the Sketch CommandManager and select the Front Plane as the sketching plane; the sketching environment is invoked and the selected plane is oriented normal to the view.
4. If the grid is displayed, invoke the Document Properties - Grid/Snap dialog box and then clear the Display grip check box from the Grid area to hide the grids. Next, invoke the System Options -Relations/Snaps dialog box and clear the Grid check box from the Sketch snaps area.
5. Invoke the Document Properties - Units dialog box and set the units to millimeters and degree for measuring linear and angular dimensions, respectively. However, if you have selected millimeters as unit while installing SOLIDWORKS, you can skip this step.
5. Move the cursor horizontally toward the right and draw a horizontal line of length close to 17.5 mm, refer to Line 2 in Figure 4-25.
6. Move the cursor vertically upward and draw a vertical line of length close to 15, refer to Line 3 in Figure 4-25.
7. Move the cursor horizontally toward the right and draw a horizontal line of length close to 14.5 mm, refer to Line 4 in Figure 4-25.
8. Move the line cursor vertically upward and draw a vertical line of length close to 67 mm, refer to Line 5 in Figure 4-25.
9. Move the line cursor horizontally towards the left and draw a horizontal line of length close to 7 mm, refer to Line 6 in Figure 4-25.
10. Move the line cursor vertically upward and draw a vertical line of length close to 101 mm, refer to Line 7 in Figure 4-25.
11. Similarly, draw the other entities of the sketch. For dimensions, refer to Figure 4-24. The sketch after drawing all the entities is shown in Figure 4-26.

Adding Re lations to the Ske tch
Next, you will add the required relations to the sketched entities.
1. Right-click in the drawing area and then choose the Select option from the shortcut menu displayed.
Next, press and hold the CTRL key and select the start point of the Line 1 and then select the origin for applying the horizontal relation, refer to Figure 4-27. Release the CTRL key after the selection; a pop-up toolbar is displayed, refer to Figure 4-28. Choose the Make Horizontal button from the pop-up toolbar; the horizontal relation is applied to the selected entities. Click anywhere in the drawing area to clear the selection set.

If you select an entity, group of entities, or feature and do not move the cursor, a pop-up toolbar will be
displayed. Remember that this toolbar will disappear, if you move the cursor away from the selected entity or feature.
2. Press and hold the CTRL key and then select the horizontal lines one by one, refer to Figure 4-27. Next, release the CTRL key after selecting the lines; a pop-up toolbar is displayed. Choose the Make Collinear button from it to apply the collinear relation. to apply horizontal relation to the horizontal lines and vertical relation to the vertical lines of the
1. Invoke the Smart Dimension tool by using the Mouse Gesture. Next, select the inner vertical line of length 135 mm (refer to Line 1 in Figure 4-25).
2. Select the vertical centerline and move the cursor to the other side of the centerline; the preview of linear diameter dimensioning is attached to the cursor. Next, click to place the dimension below the sketch, refer to Figure 4-29 for the placement of dimension. As soon as you click the left mouse button to place the dimension, the Modify dialog box is displayed.
3. Enter 100 in the Modify dialog box and press ENTER; the linear diameter dimension is applied between the selected entities. Also, note that the symbol of centerline is displayed above the cursor. It indicates that the centerline is still selected and you can directly select the other entities of the sketch to apply linear diameter dimension with respect to the selected centerline.
The linear diameter dimensioning is used to dimension the sketch of a revolved component. If you dimension the sketch of the base feature of the given model using the linear dimensioning method, the same dimensions will be generated in the drawing views. This may be confusing because in the shop floor drawing, you need the diameter dimension of a revolved model. To overcome this problem, it is recommended that you apply the linear diameter dimension to the revolved components.
4. Select the inner vertical line of length 15 mm, refer to Line 3 in Figure 4-25. As soon as you select the vertical line, the preview of the linear diameter dimension between the selected vertical line and the centerline is attached to the cursor. Next, click to place the dimension below the sketch, refer to Figure
