COMMANDS USED TO LABEL AND MARK PATTERNS
1. DRAFTING LINES
The Blue Drafting Lines and the Yellow Dimension Lines are turned on and off and can be DELETEd using the fly-out commands found on the OPTIONS pop-down menu under Drafting Lines. CPM has the ability to draw lines on different "LAYERS"; that is, it thinks of the lines as though they are drawn on overlapping layers of clear plastic or acetate. C.P.M. allows you to "turn off" the LAYERS of lines so they do not show on the screen if you find them visually distracting.
In C.P.M. the blue and yellow lines included with the basic block are on LAYERs below the pattern seam lines. The originating purpose for including these lines is educational. For students who are learning pattern drafting, seeing the drafting process seemed essential. Additionally, being able to ZOOM in and check the dimensions of important drafting lines allows one to check up on whether measurements were correctly entered. Most importantly they provide important reference points for pattern marking and flat pattern manipulation.
IMPORTANT: if you move your pattern pieces around while the Drafting Lines are turned OFF, the Drafting Lines will stay where they are. If you add another basic block to the drawing, the process will automatically turn the Drafting Lines back on. This will lead to a confusing tangle of lines.
Therefore, when planning your order of work with your pattern, you need to make whatever matching marks or lines that you know you will need for your work process with the Drafting Lines turned on and then go through the process of DELeting the Drafting Lines.
