ME 20 Lab: AutoCAD Tutorial 1 Review

Any questions?

ME 20 Lab: Design Project

Fall 2012

Design Project: Requirements

• Indentify design problems (recognition of a need)

• Explore alternative solutions (conceptual design)

• Present in poster form your most promising solution

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

“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

ME 20 Lab: Tutorial 2

AutoCAD:New commands

New Commands

• OSNAP• MOVE/COPY• TRIM/EXTEND• FILLET• OFFSET• PATTERN• MIRROR

Review: Object Snap [OSNAP]

• Status/Option bar:

• Right click “OSNAP” and select “Settings”

• Left click to turn on and off

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)

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

Trim Example

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

Extend Example

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”

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

Offset Example

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

Problem with Offset

Mirror

Why draw all this: When you only need to draw this:

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

Array

Likewise, you can do this: With just this:
