inflatable boat drafting help
in Applied Mathematics
Posted
Hi all, I'm looking for help with drawing some paper plans for an inflatable boat.
the problem i have is working out the curves for a tube mitre joint, that can be drawn on a 2d pattern that relates to its 3d shape- is there an easy mathematical formula for drafting this?
I'm really bad at explaining things so have taken a couple of pics....
the cut in this pic below is an s shape, doesn't show up well.
when in 3d the cut is a perfect straight line.
the only method i can think of is to use a 3d template (piece of pipe) cut to the required angle and mark out the fabric in its inflated state.
Cheers
Simon
