Personal Patternmaking Novice - using CADTERNS Version 5 for Windows

Personal patternmaking using the Fit-FIRST System begins with taking your measurements and creating your own personal sloper patterns.  Then you cut and sew a test garment to pinch-fit in order for it to feel comfortable and look attractive.

With the CADTERNS 100 Series you will use your personal slopers to learn how to make personal patterns manually. Using traditional flat patternmaking techniques with manual drafting tools, you will learn how to accomplish specific tasks of dart art, adjusting fullness and applying finishes.

Using either the Lite or Pro version., you will instantaneously create personal slopers at your own computer to print or plot with your own printer or plotter.  You can modify a sloper to meet your personal fitting preferences then learn how to use them to to style new patterns using traditional flat pattern design techniques and manual drafting tools.  You can also use your fitted sloper to alter other patterns for personal fit.

It is recommended that you become familiar with manual techniques before using digital techniques.  When patternmaking digitally, manual techniques can provide a quick and comforting cross-reference.

A brief comparison of manual patternmaking with the 100 Series and Digital (Computer-Assisted) Patternmaking with the 200 series follows:

Consideration Manual Patternmaking Computer-Assisted Patternmaking
Cost Initially low Initially high
Time Quick to start

Eventually cumbersome

Slow to start

Long term benefit

Difficulty Low Initially medium to high
Equipment Ruler, T square, right angle triangle, calculator, compass, French curve, large work surface Computer plus printer or plotter
Supplies Pencils, erasers, tape, graph paper Printer cartridge or ribbon, paper
