Re: [sketch-users:171] Draw cube in 2 lines[sketch]

[Alex]

Here's my method (it has 3 lines if you ignore the translation). It
first creates a square then "extrudes" it:

It's part of a library, it's not standalone. The styles are defined in
defaults.sk. "e_xtrastyle" is named like this because I wanted to mark
it as private (and it couldn't begin with an underscore).

See this page for details on how to use the library:

http://alexdu.github.com/sketch-lib/

You can look in defaults.sk and extrastyle.sk and copy the styles from there.

Yes, scroll down on that page for links :)

I've found Kjell's pages to be very helpful in learning Sketch.

Even though I'm a bigger fan of PSTricks, PGF/TikZ seems much more faster and better way to resolve a problem. Found the links. Thanks again.
