we are trying to convert the attached ON SumSurface into our own data structure. When selecting the surface in Rhino and hitting F3, you can see the following information:
start = (97.7145,0,0)
end = (97.7145,163.059,-94.1421)
domain = 0 to 188.284
line length = 188.284
This is also the information we are getting when trying to access and convert this surface in our code. But this information is actually wrong, there seems to be a hidden transformation or something like that.
When checking the surface via “Analyze - Diagnostics - List”, we can find the correct information, which is
curve3d[ 4]: ON_LineCurve domain(0,175.793) start(97.7145,-168.059,85.4819) end(97.7145,-15.8181,-2.4144)
Can anybody tell us how to access this correct information in the code?
