Do I need a separate CAD engine to use Pythagoras?
		No. Pythagoras has its own built-in CAD engine.

		Will Pythagoras be able to read my existing DWG files?
		Yes. Pythagoras can read and write to DWG files and DXF files.

		Does Pythagoras have Coordinate Geometry built-in?
		Yes, Coordinate Geometry function is built into Pythagoras. As a matter of fact, most Coordinate Geometry is done in the background, while you're drawing.

		Will it take me a long time to learn Pythagoras?
		Not at all. This is one of Pythagoras' key success factors. Pythagoras can typically be learned in about 2 days.

		What's the difference between the Windows and Macintosh version?
		There is no difference. As a matter of fact, both version use the exact same file system, so a drawing started with the Windows version, can be continued with the Macintosh version.

		Can Pythagoras create an accurate surface from elevation points, without requiring break lines?
		Yes. Pythagoras creates a digital terrain model from elevation points and, can also use break lines, if needed.
