Software for drawing lines, squares, curves etc.

[Fredrik]

I need something that I can use to draw a few simple 2D images, that don't have to look pretty. I really mean "draw" (with the mouse) and not generate from a formula, and a minimum requirement is that the program can at least let me try to draw a smooth curve with the mouse and then smooth it out for me, so it looks roughly like something I could have drawn with a pencil. (I don't think MsPaint can do that). It would also be nice (but not necessary) if I can select a shape I have drawn and rotate it by any angle.

paint.net is bit better than mspaint

You can use Microsoft Visio (information about it can be found in http://en.wikipedia.org/wiki/Microsoft_Visio)
You can also use open source software Dia (http://dia-installer.de/index_en.html) for drawing your required shapes.
Your drawing can be saved in many formats like eps, bmp, jpg, png, tif and so on.

Thanks guys. Paint.net looks like it's just for editing photos. Dia appears to be good enough for my current purposes.

I've found Excel pretty useful for some basic drawing.
