Dressing Up “In Shells & Threads”. IE 1225 Sections 3.6/3.7 J. Voss & R. Lindeke. Start With a Center Axis and Profile following constraints!. Shelling out the shaft: use the Bottom Face “to remove”. Likely The Pad is Reversed to Pass Through the Part!. As a Wireframe View:.

Dressing Up “In Shells & Threads” IE 1225 Sections 3.6/3.7 J. Voss & R. Lindeke
With 2 Draft (and reversed Arrow) using the top face as Neutral!
Make a Circle – Pocket it through the “Pad” – then Fillet the Inside Edge of the Pad
Circular Patterns in Modeling too! (Subset of Transformations in this environment)
The Counter bored Hole – here we need 4 instances – which includes the original! (unlike in Sketcher) This whole thing was quick and easy – hope one like it appears on the Mid-Term next Wednesday!
Set the Lines at the Complement of the Angles Shown at this step in the tutorial: (86.538 & 83.077 respectively)
While Profiling – Use Computed Angles – Set Lengths for the ‘top-arc’ Note the Construction Elements (circles and lines)
Be careful while working it out – Set the Angles as CONSTRAINTS after profiling (last to be sure)!
Seriously COOL! – But Reverse Direction! Hum … Better save here – too much time is invested!
Making another Circular Pattern: Pick the Pocketed Slot as Object – and Top face of the Pad of the (original) tooth as reference element
Build this sketch – Then Quick Trim to get Pocket Patterns – Pocket up to last – And Mirror about ZX plane
For the “Keyed Hole” – sketch the circle – add a rectangle – constrain it then quick trim the circle inside the rectangle and the rectangle inside the circle!
Build the Slot (draw and constrain a rectangle) – then Pocket it build a ‘Rectangular’ Array with 5x2 elements
After Getting the “Correct” Rectangular Pattern – play around with parameters and see the effect – but be careful – save your part before embarking on this trip!!!
