I have done this several times, you can do this within any acad version, simply type igesout have the item / part isolated in a separate drawing.  You can also export as .stl lithography format.  These have always worked for us, good luck!

Thanks for the reply...
maybe I'll have to switch to Mechanical Desktop then.

I do have another question,
What are the possible errors generated when performing a union between a cylinder and a cube for example? Both solid must be joined together, with no space in between. Can there be errors in microns that the solids does not join together to become one single solid?

Yes, good to know that now its called Autocad Mechanical... otherwise i was confused.
Like i said, i took for example a cube union with a cylinder. And in my drawing, the cylinder was perfectly aligned perpendicular to the face of the cube,to be unioned later.

In my actual drawing, it is much more complicated. there are a series of cylinders, threads, cones and flat surface solids.  In the end, the supplier to whom i sent the IGES file, told me that the solid isn't one single solid. that is why i am having trouble...

Maybe the best way to minimize such errors is to switch to Mechanical, do the 3D and translate to IGES using mechanical itself.

If you can suggest me, which will be the best software to use/buy to do such drawing...3D, then translate to IGES or STEP.

And if possible, to review the translated IGES file, just to make sure that there are no errors generated while translation.


Thanks a lot

Thank you for the valuable information.

I did download a trial version of Rhino. Trying to figure out how it works.
I think I'll buy Autocad Mechanical itself... because i am used to Autodesk.

Otherwise, thank you very much for the help.
if I'll have other questions, i will post it here itself.
