Develop 2.0 is a program which runs within Autocad 2000(tm) and at this writing is capable of
producing a development for a right angled cone or a rectangle to rectangle transition.
Just choose which development you want to produce and fill in the edit boxes, as an example
to do a round to round transition once you fill in the information, ie, large ID, small ID, Height
of cone, plate thickness and number of segments then the program will do the calculations
for the development and ask you to pick a point for the top left corner of
the developed transition.
