This is a scale drawing of my stretcher that I drew to get a better understanding to the size that I would be working at and to help generate a scale CAD model. I have been learning T-Splines the plugin for Rhino to develop the organic shape that I wish to use for my final design. 

I have spent the last few days watching video tutorials such as this one to try and understand t splines. T-Splines will give me flexibility to change and manipulate my surface of the stretcher body.
