Mean aerodynamic chord for complex wing shapes
I'm trying to figure out the MAC for a wing that's comprised of a straight section in the middle with two swept sections on either side. It's constant chord, so relatively simple. I'm just wondering if there's a way I can take the dimensions of the different wing sections (which are known) and compute the location of the MAC to determine where to put the CG?

Why don't you use the multi-panel CG calculator:
It's called a flying wing calculator but all it does is find the MAC and draw the CG based on the % you enter. So it's really a generic CG calculator.
Once you've generated your configuration you can ask it to generate a link to your configuration that you can post elsewhere. Here's an example of a wing with straight center section and swept tips:

If you have a spreadsheet program Sailplane Calc may be of interest to you. It will do what you ask for a four panel wing. There is also an article I wrote which explains its use.

MAC form planform
Here is the software that compute the position and length of the mean aerodynamic chord form a b&w picture of the planform of the wing (or airplane).
This is helpful in case of complex shape like elliptic wings.
You will find the executable, a short guide and some sample planforms.
Please, tell me your feeling about this software.
