IE 1225 – Intro to Design & Manufacturing

Week Two Using the SketcherJ. Voss & R. Lindeke

Getting Started -- remember

Start Part Design with a “Blank Sheet” -- Mechanical Design & Part Design

After we start: Pick a Logical Name

Tools_Customize_Toolbars_Restore Position

… and don’t forget the COMPASS!

Enter SKETCHER on yz Plane!

Set up grid information with Tools … Options

Allow Distortion – H: 100mm and 20; V: 100mm and 10

Make sure Parameters . Units in millimeters first!

Follow Tutorial 2.1: Spline/Circle/Pad with experimentation

Sketcher on Front Face!

Select it and then the Part Face

Construction on Projection

Smart Picking Constraints to Geometry

Pocketing:

Cornering:

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!

Making a Circle as prescribed!

Double-Clicking an ICON keeps it active for more than one Feature

Pad the Circle into the original holes surfaces:

Don’t forget to File .. SaveAs

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!

Use Constraints w/out Snap – Speedier Drawing

For Geometric Constraints – here Angle

Length – Distance Between Whatever

As long as it stays green – you are “OK”

Corner Tools – Great Care!

Red Line = Trouble!!!

Corners – Fillets (Chamfers) – Be careful!

After Pad – MORE (both above and below the X-Y Plane)

Choice of the one that shows Hidden Lines

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!
