Bend-Tech EZ is an entry level tube bending software for the home hobbyist. If your parts are simple 2D parts (parts that lay flat when completed) then EZ will most likely do the trick.

EZ provides dozens of predefined templates and has a custom part interface which allows for up to 6 bends. Additional templates are available from download. 

There are dozens of pre-defined templates to choose from. Most templates allow for center, outside and inside dimensions. While scrolling down the list of templates, they graphically show up in the window on the right. 

The templates are read in from a secondary file. This allows us to periodically create new templates and have them available for download.
