Ace....
There are a considerable number of forum readers with 10, 20, 30 and more years of CAD experience and to make a wholesale statement to "Draw One Side and Then Mirror", to me seems as though you have been reading too many magazines. For I just cannot remember seeing an A/C with a canopy on the topside and well as on the bottom side. Last year at the A.M.A. convention, in front of the M.A.N. booth were a three equally experienced CAD persons, all mentioning the poor reporting and across the board errors in their new CAD editor. What you have cited was one of their matters also. About four years ago, a person from Model Aviation attempted to inform the crowd on how some new standard for plans was going to be created. There were about ten CAD software persons in the audience who immediately recognized the representative was speaking from a graphics background. We had to repeatedly let him know that CAD is just different, and older, and those that have been doing plans for decades weren't about to be revised to meet some new standards. It was the A.M.A. who was going to have to adapt to established proceedures.
Many of the readers are well into creating model parts using CNC, laser cutting, and as now I read abrasive cutting also. For creating parts via a mirroring method will disturb the line direction and order of cutting. This has been explained very well by yet another reader in the Sou. Cal. area, and perhaps you ought to review his information some time. He is quite good on this subject.
I am still pretty well new to CAD software. Only been using it since the middle 1970's, and quickly found there are Zero Tricks, it is moreover based upon calculations to which the computer quietly does, or the person punching the buttons to the keyboard does. Accuracy is based upon years of knowledge and experience. I have done model plans for five different model kit distributors, to which I remain quiet about, but read on an individual basis their reactions. Each of the owners, propriators, or superintendants does not want to hear about any tricky things going on. For Tricky things mean that in one or two years from now the basis of design, or how to reproduce a plan has been forgotten. They want no surprises. It is my suggestion that before posting here, you post the same bit of information at the Autodesk web site or at CADALOG and see if the readers concur with your findings.
