1 Focusing on Modeling Expanding on Pads, Pockets Grooves Holes and Slots– Sections 3.1 & 3.2 R. Lindeke IE 1225 – Introduction to Design & Manufacturing

2 Sketch Based Tools -- Pads – Linear material addition, looking at Multi-pads Pockets – Linear material removal Shafts – Adding Materials by revolving Grooves – Removing Material by revolving Holes – different configurations to make cylindrical shapes Rib – Adds material by ‘sweeping’ along a centerline Slot – Removes material by ‘sweeping’ along a centerline Loft – add material by connecting sketched features Remove Loft – like above in reverse!

3 Why won’t it do it? Beware of Over-Constraining a sketch Typically these are Coincident Constraints (and nearly always added by CATIA) Find and Delete before trying the 3-D feature again Also be aware of overlapping edges

4 We’ll Build this structure: Toughest ideas will be building the Steps as Multi-pads

5 Beware the Coincident Constraints and  Hum  so the last two are Profiles and they must have a ‘bottom’ edge that doesn’t touch the lower one’s top edge!?!

6 The minimum offset between the profiles was about.002 mm! Else Multi-pad failed! By the way – if they must touch, we could make each step as a separate sketch!

7 Zoom-Zoom-Zoom: it helps to get edges and corners!

8 When Profiling – SET lengths and Radii!

9 Probably need Reverse Direction for the Step-Up-Arc

10 Careful when picking Projection Edges – We need the two sides of the rectangle and the inside edge of the Sectioned ‘Arched’ Item

11 Rotate the Object Around to get the inside arched Face Surface as the Limit (-10 mm)

12 A Shelled Pad: Thick–ness is 2 mm

13 Tutorial 3.2 – Looks into Advanced Pocketing and Hole-making Building Slots – use care Use care concerning Unwanted Constraints When Setting Construction Elements – also use caution!

14 Our Goal:

15 Pad the Top face and Sketch the Pocket w/ Circles – multi-pocket the overall shape at 10 mm the “holes” to 80 mm

16 Use Transform “offset” from the edges of the face

17 Draw the Spline inside the ‘Thick’ pocket, then pocket (reverse direction?) to 20 mm

18 Add the Triangle – then Re-enter Sketcher on the top. Now Draw a “Slot Line” constrained as seen When selecting the Triangle (Sk. 5) as Profile and Line (Sk. 6) a Center Curve – select from the Part (Design) Tree for building the slot!

19 Setting Hole Positions – be sure to get the sketched holes Center Points for offsets!

20 The Line Runs along the Back Face at -45 degrees (upward)

21 Setting Tapered Hole: Start on Top it’ll Track the Line you just made when set right
