3-D Geometries & Adding Sketch Planes

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

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

Create 1st reference Plane – offset from yz
![Page 5: 3-D Geometries & Adding Sketch Planes R. Lindeke IE 1225](https://reader035.vdocument.in/reader035/viewer/2022062500/5697bfee1a28abf838cb9a3f/html5/thumbnails/5.jpg)
Isometric – notice the grid away from the part – Project Circle to plane and offset (transformation)

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

Center piece was isolated and sketches were resized!

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

Our 3rd Aux. Plane – and in Iso-view to aid in sketching:
![Page 10: 3-D Geometries & Adding Sketch Planes R. Lindeke IE 1225](https://reader035.vdocument.in/reader035/viewer/2022062500/5697bfee1a28abf838cb9a3f/html5/thumbnails/10.jpg)
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!
![Page 11: 3-D Geometries & Adding Sketch Planes R. Lindeke IE 1225](https://reader035.vdocument.in/reader035/viewer/2022062500/5697bfee1a28abf838cb9a3f/html5/thumbnails/11.jpg)
All this work to get another Aux. Plane – Yes (again the power of 3-D design!)

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

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!
