The animation ? WIth a simple free Gif recorder : GifCam http://blog.bahraniapps.com/gifcam/

The volume itself in MOI ? Of course yes!
Draw your profil (s) 1 Minimum to the infinite! :)
Choose any combinaison of profils (2 familly of selectioned profils) you want following the result wanted...then Press Boolean Isect!

Click profil(s) then Press Isect

You can use Show Points for easy help for modify a profil...
Profil(s) must be "Plane" but not obligatory perpendicular or parallal to the volume!

Better to have curves closed else the Isect volume will be just a "Surface"

Draw profils before anythings
Then click rofils then press Isect!!!

If you draw a volume first you will have only one "cut" and no possibility to modify "profil(s)" !

Volume must be result of an Isect of several profils ! ;)
