![]() ![]() Adobe Illustrator for some clarification drawings, simply because I'm used to it from my career in graphics. ![]() I'm using some computer tools where I think it's necessary - MS Excel, and possibly Peter Garrison's 'Loftsman' for parts of the fuselage loft. That includes all the drawings, because they're for me to use in my own shop. I've learned both 2D and (older) 3D systems quite well in the past, but I'm doing my airplane on paper, with a pencil and a pen. CAD has a purpose and a place, and I think it's a wonderful thing. #Deltacad designers choice software#I can't speak to any of the individual software packages he mentions, because I haven't used them, but if you can't design an airplane on paper with a pencil, you're not going to be able to do one in CAD. I cannot agree more with nickec's overall assessment above, and that applies equally to the Rutan quote. But I'm interested in designing an airplane, not learning a new life-skill in using OpenVSP. I'm sure if you take all their tutorials and spend a sizable chunk of time learning the system's method of assembling the geometry of an aircraft, it does all they claim. The process they seem to be following with its use bears no relation to any airplane design workflow I've ever seen. Completely counter-intuitive, and I spent more time wrestling with the system than I did creating actual geometry. ![]() In practice, I found the user interface comparably opaque to concrete. The concept behind it is interesting, and I really like the theory of parametric modeling and all the benefits that come with it. I have seen multiple references to Burt's assertion and I agree that pencil and paper, and simple balsa and foam models, speed the design process. ![]() The above quote comes from Burt Rutan - Aviator Sunglasses Randolph Engineering AO Eyewear Bolle Serengeti Rutan feels that using CAD slows down the design process. " One concern Burt Rutan has is the reliance of the new generation of designers on computer aided design (CAD) computer programs. The price is the mental work to master the systems. So if you were serious enough to make molds for your design OpenVSP/FreeMill is the most bang for your buck. OpenVSP is very powerful and can send accurate models to other powerful programs like FreeMill. RcCAD also makes "pretty" 3D models quickly but the "logic" of the user interface again requires some practice. This assumes the person wants to keep costs as low as possible.įor making "pretty" models fast and accurately, nothing beats OpenVSP - but you must understand the program and get used to the "logic" behind it. It is my opinion that a person who experiences challenges in using CAD will find the learning process easier if they start with DeltaCAD and then move up to MecSoft. The import and export functions of the MecSoft programs are very useful for manipulating files.įree CAD/CAM Software Package from MecSoft Corporation It will not only do drawings but will provide files which can run CNC machines. Profili 2 - wing airfoils managing, printing and analysis softwareįreeMill is 3D and also totally free. DevFus provides some of what you seem to be seeking. RcCAD will show cross sections of fuselages and although it takes some practice it can produce reasonable first pass 3D models.Īt the site there are several programs which you might like. Although only 2D it is very fast and very useful. #Deltacad designers choice trial#The free trial is long enough to get quite a lot done. It includes a short tutorial in the help section of the program. The learning curve of CAD cannot be avoided - at least at the present.ĭeltaCAD is probably the easiest CAD system to learn. ![]()
