1. 3-D Geometries & Adding Sketch Planes R. Lindeke IE 1225

2. Tools in Play – getting started We will continue studies of drafting plane development Sketch originates on yz plane Make a profile – useful starting point Pad it as required

3. Profiling and Circle Constrained to centers on origin (140 mm tall)

4. Create 1 st reference Plane – offset from yz

5. Isometric – notice the grid away from the part – Project Circle to plane and offset (transformation)

6. Be sure to trim upper halves of circles & line inside small circle!

7. Center piece was isolated and sketches were resized!

8. Profile on 2 nd Auxiliary plane – “shaft” it 360 around V-Axis Note: Arc has Zero offset from V-Axis

9. Our 3 rd Aux. Plane – and in Iso-view to aid in sketching:

10. Add 2 Points – centered on Pad 3 End – after a line is drawn between we make a Plane (rotated about the line 30  ) relative to the end of the PAD!

11. All this work to get another Aux. Plane – Yes (again the power of 3-D design!)

12. When Intersecting 3D Elements – make sure that you select PAD3 from the Tree – not the Face in the sketcher!!!

13. Completed -- Lots of chances to “go Wrong” 4 Auxiliary Planes are needed – offset and ‘at an angle’ Points and Lines too – in the Modeling environment Work Carefully – If you can’t Pad at First – Cancel and return to sketcher to repair!
