IE 1225 – Intro to Design & Manufacturing
Week Two Using the Sketcher J. Voss & R. Lindeke
2
Getting Started -- remember
Start Part Design with a “Blank Sheet” -- Mechanical Design & Part Design
3
After we start: Pick a Logical Name
4
Tools_Customize_Toolbars_Restore Position
… and don’t forget the COMPASS!
5
Enter SKETCHER on yz Plane!
Set up grid information with Tools … Options
6
Allow Distortion – H: 100mm and 20; V: 100mm and 10
Make sure Parameters . Units in millimeters first!
7
Follow Tutorial 2.1: Spline/Circle/Pad with experimentation
8
Sketcher on Front Face! Select it and then the Part Face
9
Construction on Projection
10
Smart Picking Constraints to Geometry
11
Pocketing:
12
Cornering:
13
Sketching XY Plane and Cutting by that Plane – drawing on the inside!
The Cutting Plane ICON may be hidden – check Tools/Customize and any light >> icons!
14
Making a Circle as prescribed!
Double-Clicking an ICON keeps it active for more than one Feature
15
Pad the Circle into the original holes surfaces:
16
Don’t forget to File .. SaveAs &/or Save Management when we enter the Drafting WB
17
Constraints!!!! Be careful – constraints are “Super Powerful” but can get you into trouble – especially Auto-Constraints Use these Constraint Tools – double click them to hold!
18
Use Constraints w/out Snap – Speedier Drawing
For Geometric Constraints – here Angle
19
Length – Distance Between Whatever
20
As long as it stays green – you are “OK”
21
Corner Tools – Great Care!
Red Line = Trouble!!!
22
Corners – Fillets (Chamfers) – Be careful!
23
After Pad – MORE (both above and below the X-Y Plane)
Choice of the one that shows Hidden Lines
24
Now go to work Begin Developing Parts labeled:
2.1b, 2.1c, 2.1d, 2.1f in the handout Due next Wednesday in Class! Examine the parts before you begin Choose Principle Plane(s) Plan any Auxiliary views for further sketching of details Think First – Draw Later! A good Design Engineer makes a drawing plan before a Drawing!
