  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 1st 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 2nd Auxiliary plane – “shaft” it 360 around V-Axis Note: Arc has Zero offset from V-Axis

  9. Our 3rd 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!
