1. ME 20 Lab: AutoCAD Tutorial 1 Review
Any questions?

2. ME 20 Lab: Design Project
Fall 2012

3. Design Project: Requirements
Indentify design problems (recognition of a need)
Explore alternative solutions (conceptual design)
Present in poster form your most promising solution

4. Design Project: Milestones
“Bug” List – September 19
5 ideas for new products or modifications. Think of things that “bug” you
Problem Sketch – October 17
A 3-D sketch of the problem
Solution Sketch – October 31
A 3-D sketch of your proposed solution
Open Labs – Weeks 14 and 15
Due Date: Friday, December 14 5:00 – 6:00

5. “Bug” List Come up with a list of 5 things that “bug” you
Should be things with a physical solution but you do not need to have a solution just yet
Write them down with a sketch (if you’d like) and submit next lab

6. ME 20 Lab: Tutorial 2
AutoCAD:
New commands

7. New Commands
OSNAP
MOVE/COPY
TRIM/EXTEND
FILLET
OFFSET
PATTERN
MIRROR

8. Review: Object Snap [OSNAP]
Status/Option bar:
Right click “OSNAP” and select “Settings”
Left click to turn on and off

9. Move and Copy If you need to move 1 or more objects:
Select the objects
Use:
Modify > Move
Move Tool
“move” or “m”
Select a “base” point (any is fine)
Move and place selection where you want
If you need to copy 1 or more objects:
Same as above, using:
Edit > Copy
Copy Tool
“copy”
CTRL + C (use CTRL + V to paste and place)

10. Trim Tool Trim unwanted portions of a single geometric figure
Can use to make arcs out of circles
Modify > Trim or “trim”
Select “trimming boundary” > “Enter”
Select segment to trim

11. Trim Example

12. Extend Tool
Extend a line that does not go as far as you’d like to a boundary
Must have the “end limit” defined in drawing
Modify > Extend or “extend”
Select “end limit” > “Enter”
Select side to extend

13. Extend Example

14. Fillet Tool A fillet is a rounded corner: MUST define radius (default
is set to 0)
Ways to begin a fillet:
Modify > Fillet
Fillet tool
“fillet” or “f”

15. Fillet Tool Type “radius” and input desired radius
This step is very important otherwise the tool will not work correctly
Select the two lines to create
the fillet between
These do not have to be at
90° angle

16. Offset Example

17. Offset Create the object you want to offset Begin offset by:
Modify > Offset
Offset tool
“offset” or “o”
Specify the distance you want to offset
Select the object to offset and click on the side you’d like it to offset to
May have to repeat multiple times to get desired shape

18. Problem with Offset

19. Mirror
Why draw all this:
When you only need to draw this:

20. Mirror Look for symmetry in objects Start mirror by:
Modify > Mirror
Mirror tool
“mirror”
Select objects you would like to mirror
Draw a line you would like to mirror objects about
Select “N” or “Y” – if you would like to erase original object

21. Array
Likewise, you can do this:
With just this:
