CAD Exam 1
The line segment from point #1 to point #2
Waist Measurement
what will we be doing
We will work with OptiTex, be exposed to Lectra (very complex); aware that there is another system, Gerber
Rulers are good for
Working Area
slopers
a building block-- used just to make other styles from
pattern
components needed to make a hoodie
A company brand new with CAD will use_____?
digitizing
pattern piece
ex: the hood in the pattern or the sleeve hood=2 pattern pieces(mirror image provides 2)--CAD will do this
most expensive component
fabric
Naming Files
first initial : last initial : name of file Example: AK5ptpocket
the _____ must always be on pattern piece
grain line or base line
when placing point (digitizing)...
less is more (curve, 3)
Grading
make different sizes Fits everyone on the size range
De-skills the
marker making process
Cad reduces
marking time
sweep
means all around hemline
Handles smaller orders
more efficiently
PDS 15 (optitex)
pattern design system/software
Labor savings in
pattern making and marker making
Lines on Pattern=
Different Sizes
A company that has no technology and gets CAD, will get their styles into the system by
Digitizing
Grain Line gives
Direction
Blue Frame Mark
Electronic can not receive a single (1/2)
Working Area
Everything a designer can do w/ their manual perspective can be done in this function CAN NOT CUT OUT
Every pattern piece will have a
Grain Line
Working Units
INCH SQ. FT.
Digitizer
Is an electronic pad
Tool box located to the
Left
The line segment from point #2 to point #3
Length Measurement
marker making
Marker 15---Diamino/marker making V6R2
Tweak pattern to be
Mass Produced
PDS equivalent in Lectra
Modaris V8R1
Basic foundation CAD system creates shape?
On X and Y axis (digitize geometry)
PDS
Pattern Design System
half symmetry
set mirror line
what do darts create?
shape
Movement
use top 2 boxes
Improves pattern quality:
• Fit • Shape • Style • Manufacturing efficiency
Reduces design time for
• Pattern making • Pattern grading • Style / Line composition • Special orders
3 apparel CAD companies
(1) Lectra Systems--french (2) Gerber Garment Technology --USA (3)Opti-Tex---German
A company who does things manually is
- Labor Intensive - Time Consuming
Anything that is on file will be in the
Pieces Window
Typically use draft for
Simple Shapes
Bottom of screen is considered
Status Bar/ Command Line
The line segment from point #3 to point #4
Sweep Measurement
Status Bar/ Command Line
Tells the status Tells you what function you are in

Garment manufacturing flowchart
1. Design/ sketch (PDS) 2. pattern design(PDS) 3. sample making 4. production pattern (PDS) 5. grading (PDS) 6. marker making (Marker) 7. spreading 8. cutting
4 main ways to get pattern into CAD
1. digitizing 2.Drafting a brand new pattern (from scratch) 3. make pattern pieces from existing styles (alter them) 4. electronically transfer
After you close the loop put...
2 Letter B's far apart on base lines
A garment manufacture that has a CAD system employed for a while will make a majority of their styles by
Altering Existing Styles
System works in (digitize in this direction)
Clockwise
