I am using Autocad 2010. I need to draw curved lines on the surface of a sphere, but i have no idea how to achieve this? I need to sweep a profile across the surface of the sphere.
Thanks in advance!
Neat trick dude!

Extrude intersection shape for path.
xedges to extract path
Sweep with align to path.
Union or subtract if desired.
(you might want to bump facetres to 10 and regen on the file I attached.)

I have a .Net routine in development (AutoCAD 2009+, though not tested on 2010) that allows drawing on any face of a solid. Actually, it is more a mapping routine (compared to on surface drawing) but it may be of some use. I’ll post the DLL if anyone is interested.
Thanks guys for all the help! You guys are brilliant. Seant I would really like to explore the Net routine!
Tested only with AutoCAD 2009 32bit, but hopefully compatible with 2010 and 64bit.
Also, may be compatible with AutoCAD’s 2007 and 2008 if a copy of acdbmgdbrep.dll is available.
CsVectorMap.dll is the callable routine but keep both CsVectorMap.dll and STSClib_SolSubentSel.dll together in the same folder.
To perform a mapping operation, first:
Navigate to the appropriate folder and select CsVectorMap.dll
To create “canvas” border of a selected face.
[Border will always be near WCS origin. The code responsible for the general shape and scale of border still needs some tweaking].
Create some geometry within the canvas border.
Select the “canvas” object, then select all the lines and curves to be mapped.
Warning: This is a beta routine and should be used with sensible caution. Save all working AutoCAD sessions, isolate pertinent geometry into its own file, then return mapped geometry back to it’s final location.
THis reply is awsome ! SEANT, you should forward this to the tutorial section, neat work
....always perform Beyond what is expected.
