Making a model using blender

Well written tutorials and documentation are found on the wiki.

Some tips:
  • Blender's top "menu bar" can be resized by dragging down, to reveal a preferences menu (Enable auto save on this menu, while you are at it)
  • BUG: Blender 2.44 on windows, boolean operation : union is actually difference and vice versa
  • Copying an object from one file to another (or even the same file). Remember: go into the 'OBJECT' subtree.
  • Export to STL: Remember: blender exports the currently selected object.

Keyboard short cuts:

tab - switch between object and edit mode
a - toggle between select all and select none
b - box select, select a bunch of vertices by dragging
e - extrude
g - grab
m - move object to layer dialog box
s - scale
w - boolean operation menu
shift-k - scissors

A note on Python's __exit__() and errors

Python's context managers are a very neat way of handling code that needs a teardown once you are done. Python objects have do have a destructor method ( __del__ ) called right before the last instance of the object is about to be destroyed. You can do a teardown there. However there is a lot of fine print to the __del__ method. A cleaner way of doing tear-downs is through Python's context manager , manifested as the with keyword. class CrushMe: def __init__(self): self.f = open('test.txt', 'w') def foo(self, a, b): self.f.write(str(a - b)) def __enter__(self): return self def __exit__(self, exc_type, exc_val, exc_tb): self.f.close() return True with CrushMe() as c: c.foo(2, 3) One thing that is important, and that got me just now, is error handling. I made the mistake of ignoring all those 'junk' arguments ( exc_type, exc_val, exc_tb ). I just skimmed the docs and what popped out is that you need to return True or

Using adminer on Mac OS X

adminer is a nice php based sqlite manager. I prefer the firefox plugin "sqlite manager" but it currently has a strange issue with FF5 that basically makes it unworkable, so I was looking for an alternative to tide me over. I really don't want apache running all the time on my computer and don't want people browsing to my computer, so what I needed to do was: Download the adminer php script into /Library/WebServer/Documents/ Change /etc/apache2/httpd.conf to allow running of php scripts (uncomment the line that begins: LoadModule php5_module Start the apache server: sudo apachectl -k start Operate the script by going to localhost Stop the server: sudo apachectl -k stop
