People get used to the weirdest things. After searching and reading about this subject, I'm convinced that the isometric view is just a relic from the past, and the only reason it seems to even exist is that, in the olden days, it was easier to draw by hand. Even a simple rectangle looks like a trapezoid that gets wider and wider in isometric view when viewing from a steep angle (the sides are literally pointing in opposite directions!) ,and as it says on wikipedia "...the result is a perceived distortion, as unlike perspective projection, it is not how human vision or photography normally work. It also can easily result in situations where depth and altitude are difficult to gauge..." It's like I'm stuck rotating drawings by a 9-year-old. Sure, I can live my life without perspective view in mastercam, and I'll get used to it, but coming from programs that have realistic 3D graphics (e.g. Autodesk's perspective with ortho faces), this seems ridiculous.
