Dave its water jet/plasma so the head has all the rotation and 5 axis needed, Viesturs, I cannot see the item as heekscad bombed on the stl file but gcode can handle the maths so you can can just do the maths in the gcode program.
Also then is another way which you can develop from sheet metal practice http://search.sheetmetalworld.com/news/articles/197.cfm and develop the paths in gcode break into as many triangles as needed for accuracy Dave Caroline On Sun, Mar 13, 2011 at 5:30 PM, dave <[email protected]> wrote: > On Sun, 2011-03-13 at 19:02 +0200, Viesturs Lācis wrote: >> 2011. gada 13. marts 17:45 Lars Andersson <[email protected]> rakstīja: >> > Suggest a search on the keyword "lofting", this is similar (maybe) to your >> > problem. >> >> Unfortunately majority of results were talking about boat hulls, rest >> of them - how to use lofting function in 3ds max.
