Usage:
In the Ruby Console type TIG.data2frusta - select the data.txt file that is in the format for each line of
x0 y0 z0 d0 x1 y1 z1 d1
where the conic-start 0 center is at [x0,y0,z0] and has the diameter d0
and the conic-end 1 center is at [x1,y1,z1] and has the diameter d1.
Each line of code makes a grouped conic frusta - to change from 24 sides or another group-name edit the code at the ### noted lines...
It is one step undo-able, canceling at the file dialog stops the tool...
