PROGRAM STRUCTURE THEORY
1. DESIGNED FOR COSTUME MAKERS
C.P.M. was designed for use by costume pattern-makers. The program is , of course, useful to anyone engaged in custom garment construction. It's primary mission is to draft very accurate basic blocks quickly and easily and with technical accuracy.
The traditional process of drafting patterns requires an amazing amount of mind-processing of mathematical, geometric, past experience knowledge and visual intuition. It requires a totally focused mind to perform without mistakes. Mechanical technical accuracy in drafting is very important. The combination of the artistic mind-power and a fondness for technically accurate detail required for pattern making does not commonly occur in human beings. For these reasons, truly good pattern_makers are a rare commodity.
Principle pattern_makers also function as supervisors for the sewers. Many find it difficult to effectively perform pattern making tasks during the same time. Often they end up coming in early or staying late in order to have "quiet time" when they can focus on the patterning process. This program makes it possible for less skilled workers (including student and volunteer crew members) to make up custom-sized blocks. This program appears to cut the labor process by 2/3. Additionally, patterns and garments that are made up from these blocks are so accurate that they eliminate the need for at least 2 of the fittings normal to the construction process.
2. TASKS IT WILL PERFORM
In addition to drafting custom-sized patterns, the program will perform flat pattern manipulation (cut and spread), resizing and marker layout. It will create garment industry standard-sized patterns (you decide what a standard size is and type in the measurements).
The length of time it will take you to perform slash & spread patternmaking will not seem to be much faster than doing it the traditional way with scissors and paper. However, C.P.M. quickly performs tedious mechanical operations, such as drawing seam allowances, making facings, MIRRORing a 2nd side for a pattern on the fold, making duplicates, etc. It automatically builds in a mechanical accuracy that many aspiring pattern makers could not achieve using traditional methods.
As a result, pattern making using C.P.M. can become a painless and successful operation for costume makers who find it difficult to deal with detailed accuracy and the tedium of drafting.
