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 dont 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 gtgt 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
Dont forget to File .. SaveAs
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 Monday 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!
