Control Pad Task:
Main commands used:
- Ruled
- Through Curves
Process: Construct a series of datum planes that you use as attachment faces for sketch profiles. You will create and constrain three separate sketch profiles. Then you use these sketch profiles to create ruled bodies. Remember to place your geometry on separate layers.
1. Create a new part file in your home directory called control_pad. Make sure to set the units to Millimeters.
2. Create an offset datum plane from the Z-X plane at a distance of 150mm.
Create another offset datum from the first offset datum by 75mm.
3: Create a sketch called Profile_1 on the Z-X plane of the datum coordinate system. Make sure the vector normal (Z-axis of the sketch) points in the -Y direction.
Use the X datum axis as the horizontal reference. Make sure the X vector of the sketch points in the X direction. Create the curves as shown.
Make Line 1 collinear to the vertical datum axis or plane, and Line 2 collinear to the horizontal datum axis or plane.
Place the arc's center on Line 1.
Mirror the sketch about Line 1.
Create the sketch dimensions as shown.
Use Insert | Sketch in Task Environment
Assure Continuous Auto Dimensioning is toggled off.
Finish the sketch.
4: Create a sketch called Profile_2 on the 150mm offset datum plane. Make sure the vector normal (Z-axis of the sketch) points in the -Y direction. Use the X-Y datum plane as the horizontal reference. Make sure the X vector points in the X direction.
Create the curves as shown.
Make Line 1 collinear to the vertical axis or plane, and Line 2 collinear to the horizontal axis or plane.
Place the arc's center on Line 1.
Mirror the sketch about Line 1.
Create the sketch dimensions as shown.
It may help to hide the first sketch to avoid confusion.
Finish the sketch.
5: Create a sketch called Profile_3 on the 75mm offset datum plane. Orient the sketch in the same way the first two were oriented. Create the curves the same way you did the first two sketches.
Make Line 1 collinear to the vertical axis or plane, and Line 2 collinear to the horizontal axis or plane.
Place the arc's center on Line 1.
Mirror the sketch about Line 1.
Create the sketch dimensions as shown.
Finish the sketch and hide all of the datums.
6: Create a ruled body, goto Insert | Mesh Surface | Ruled, using Profile_1 and Profile_2. Make sure to select both profiles from the same location to force the arrows in the same direction. Use Parameter as the Alignment and activate Preserve Shape.
7: Create a second body but this time use Insert | Surface | Through Curves command using Profile_2 and Profile_3. Again, select both section strings in the same manner. Use Parameter as the Alignment and activate Preserve Shape.
Set the Continuity for the First Section to G1 (Tangent) and select the 5 faces of the first solid body as shown. Select Perpendicular in the Flow Direction drop down menu.
8: Unite the two bodies to complete the operation.
9: Select OK.
