Drawing Software

[Klare]

Hi everybody!
I'm looking for a good software for Mac to build up geometrical drawings...Especially I need to draw lines, axis and geometrical figures (circumferences, squares...), measure distances and angles, divide segments in equal parts and so on...Everything on imported JPG images.
Can you help me somehow, older and more experienced Mac brothers??? :apple
Thanks!
Klare.

What kind of drawing are you doing? Architecture? Mechanical?

Actually, I'm working on a series of radiographic images of elbows.
I already have software to manage this kind of images, especially DICOM (I usually use Osirix), but now I'm working on pictures of Xrays films, and I really need to sort out axis of bones, angles between them and radius of curvature, in a more specific and precise way...
