Hole Plate with Edge Chamfers

Create a 3D part using a sequential operation. STEP 1: Create a base rectangular solid on the XY plane. The width (X-axis) is 275.9mm, and the height (Y-axis) is 130mm. Extrude it to a thickness (Z-axis) of 20mm. Position the bottom-right corner of this rectangle exactly at the origin point (X:0, Y:0, Z:0). This means the rectangle extends into the negative X direction down to X:-275.9. STEP 2: Cut 14 through-holes through the entire 20mm thickness at the following exact X,Y center points: Hole 1: Diameter 22.1mm at X:-85.1, Y:38.31 Hole 2: Diameter 8.2mm at X:-15.0, Y:27.71 Hole 3: Diameter 8.2mm at X:-44.85, Y:105.86 Hole 4: Diameter 8.2mm at X:-228.65, Y:48.16 Hole 5: Diameter 8.2mm at X:-212.15, Y:105.86 Hole 6: Diameter 11.0mm at X:-112.9, Y:20.86 Hole 7: Diameter 11.0mm at X:-118.35, Y:96.46 Hole 8: Diameter 11.0mm at X:-183.75, Y:91.71 Hole 9: Diameter 11.0mm at X:-178.35, Y:16.16 Hole 10: Diameter 15.0mm at X:-81.3, Y:79.81 Hole 11: Diameter 15.0mm at X:-113.55, Y:111.81 Hole 12: Diameter 82.07mm at X:-148.35, Y:56.31 Hole 13: Diameter 13.0mm at X:-235.5, Y:115.0 Hole 14: Diameter 13.0mm at X:-252.0, Y:57.31 STEP 3: Apply a chamfer/cut to the left edge. The cut starts at the bottom-left corner (X:-275.9, Y:0) and angles upward at 16 degrees from the horizontal, stopping at a vertical height of Y:28.53. Remove the material below this line. STEP 4: Apply a chamfer/cut to the top-left edge. Cut the top-left corner downward at a 106-degree angle measured from the horizontal top edge, leaving a flat top edge of 29.1mm wide. STEP 5: Apply a chamfer/cut to the right edge. Start at a vertical height of Y:30.49 on the rightmost edge (X:0), and cut inward toward the top edge at an angle of 111 degrees from the horizontal. Remove the material outside this line.
