First of all this software is amazing, I love it.  My question... Is there a way to transform parts that need to wrap around things or bend around things like tractor treads or flexible hoses?  I want to fit the tractor tread around gears and in another case I want to attach a hose and have it make a 90 degree turn, all for a model I'm making.
Please be specific if there is a solution.
Thank You so much and hope to hear form you soon.
John
