6. From the In Graphics toolbar, clickZoom In :

• Click atX1to define the upper-left corner of the zoom box. • Click atX2to define the lower-right corner of the zoom box. • Middle-click to release the zoom in tool.

7. From theSketchinggroup, selectCenterline from the Centerline types drop-down menu:

• Click atX1to start the centerline.

• Click atX2to make the centerline horizontal. • Middle-click to release the centerline tool.

8. From theSketchinggroup, select3-Point / Tangent End from the Arc types drop-down menu:

• Click on the vertical reference, below the centerline atX1to place the start point of the arc.

• Click on the centerline atX2to place the endpoint of the arc. • Move your cursor to size the arc, then click nearX3to complete

the arc.

• Middle-click to release the arc tool.

Use a tangent constraint to make the arc tangent to the horizontal centerline. If you see aT(tangent constraint symbol) at the end of the arc, it is already tangent and you can skip this task. 9. From theConstraingroup, clickTangent :

• Select the arc and then select the horizontal centerline.

Notice aTis now displayed at the end of the arc, signifying it is tangent to the horizontal centerline.

Do not forget, you can useUndo andRedo if you make a mistake while learning to use sketcher.

UseNormal to create a normal, linear dimension that will define the position of the centerline.

10. From theDimensiongroup, clickNormal : • Select the top edge of the wheel atX1. • Select the centerline atX2.

• Middle-click atX3to place the dimension.

• Edit the value of the dimension to.5and press ENTER. 11. Double-click the radius dimension’s value, edit it to25and press

ENTER.

The radius dimension is a weak dimension that was automatically created, you may have to zoom out to see it.

Sketch a line that is at approximately a 45 degree angle, from the endpoint of the arc to the top edge of the wheel.

12. In theSketchinggroup, selectLine Chain from the Line types drop-down menu:

• Snap the start point of the line to the endpoint of the arc, shown at

X1.

• Snap the endpoint to the blue reference line at the top of the wheel, shown atX2.

The blue reference line at the top of the wheel was created when that edge was selected to create a dimension. If it was not there, you could have added it while sketching the line by pressing ALT and selecting the edge.

UseNormal to create horizontal dimensions that define the location of the upper and lower endpoints of the line.

13. From theDimensiongroup, clickNormal :

• Select the vertical edge shown atX1.

• Select the upper endpoint of the line, shown atX2. • Middle-click atX3to place the
