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

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

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
