All of the math and fault tolerances are built in. It's also easy to train a non-AutoCAD operator in its use. While there are manual facilities for nearly every contingency, there are some technical illustration procedures that by their nature are not convenient, without the aid of scripting. Both the view rotation and extrusion are mathematically correct to a degree far in excess of display and printing capability. The axes of view and extrusion are determined by selecting an appropriate radio button, and the depth of extrusion is input directly.
All conversions occur instantly, and appear as solids without tessellation or construction lines.
This is convenient in situations where isometrics have been created directly from material samples, or when orthographic drawings are not available. The difference in execution speed is significant. There are few known exceptions that may cause critical errors. These warnings are worth noting, since the associated errors can be demonstrated and, once instigated, will inevitably lead to entire file failure . For ease of accessibility it is convenient to incorporate the binary file into a menu bar heading.
