9 r v t v t u r 6 t y r f 7 h p x r We will design this small bracket to practice the various ways of using both the T x r p u r and Q h 9 r v t workbenches for designing parts. One of the tools we will use in many different cases is the Sketching of aQ s v y r and extruding Q h q .

1. Create a new Part and select as model unit by going to U y P v B r r h y V v

2. Set the Sketcher Q v h T h p v t to 20 mm. and t h q h v to 10 by going to U y P v Q h T x r p u r

3. Go to U y P v Q h 9 v y h and make sure S r y h v is checked.

4. Click OK and exit P v .

We will first define all the x r p u r h q for the Bracket. We will start with the 3 mm. thin flange.

1. Select the Y plane and enter the T x r p u r . Draw the first sketch using S r p h t y r icon and

dimension as follows:

2. Exit Sketcher and create a Q h q with height of 26 mm above sketch.

We will now create the base pad of the part:

3. Reselect the Y ` plane and go back into T x r p u r . Use Q s v y r to sketch then constrain the

new contour to the boundaries of the existing Pad and apply the appropriate dimensions .

4. Extrude this second Q h q to a height of 4 mm.

Next we would like to create the two angle flanges (clevis).

To create this geometry, we will require an angular Q y h r at 24 Degrees with respect to the YZ plane in orderto sketch our profile. Since our drawing calls out the position of these flanges from the position of the pilot holelocated between the flanges, we will make our plane pass through the center of this hole so that we will readilyhave available the values of the extrusion limits.

Since our 24 Degrees Plane will pass through the center of one of the pilot holes, we will need to locate thishole in the model. Consequently, we might as well create all the pilot holes first.

5. Position the first hole by first selecting the reference edges, the Hole feature icon, and finally the topof the pad into which the holes are drilled. Put in the appropriate locating dimensions and the holediameter per the part drawing at the beginning of this exercise. Use the V I r option.

6. Position the second hole by first selecting the reference edges, the Hole feature icon, and finally thetop of the pad into which the holes are drilled. Put in the appropriate locating dimensions and the holediameter per the part drawing at the beginning of this exercise. Use the V I r option.

7. Create the third hole by first selecting the rounded edge the Hole feature icon , and finally the top ofthe pad into which the holes are drilled. Put the appropriate hole diameter ( " ), the hole is automaticallycentered on the rounded edge. Use the V I r option.

We will now create the 24 Degrees plane through the center of one of the pilot holes. To do it, display thePlane icon by selecting u r W v r U y i h S r s r r p r @ y r r @ r q r q

8. Select the Plane icon and create the required plane using the Plane Type of 6 t y r I h y Q y h r . Select the vertical pad wall as reference and the pilot hole as the rotation axis for the plane. Put in ! # Degrees to get the desired orientation.

9. To redefine the PartBody as the D X x P i w r p place the cursor on the PartBody in the tree then selectthe Define In Work Object command from the contextual menu.

10. Select the plane you just created and go into the Sketcher to create the following profile. As before,

constrain the profile to the existing geometry and apply the appropriate dimensions.

11. Create a h q from this sketch with a thickness of 4 mm. (use the ! y v v v ).

We will now create the other Clevis by using the Rectangular Pattern tool (you can find this tool underInsert/Transformation Features)

12. Click on the Rectangular Pattern Icon , select the existing Clevis, select the red edge below for thereference direction, and put in 2 instances spaced at 16 mm.

15. Create the R6 fillets (2 edges).

16. Finally, create the R8 fillets (2 fillets).
