IE 1225 – Intro to Design & Manufacturing Week Two Using the Sketcher J. 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 &/or Save Management when we enter the Drafting WB
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 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!
