Spur Gear Design Program

I need a basic spur gear generator and I've done a Google search and tried a few, but haven't found one which will generate a dxf file which will successfully dxfin to my AutoCad LT. Also the ones I've found must be used on-line and I'd rather have one which can be be loaded in my computer.
I would appreciate hearing your experiences and recommendations.

I realise this thread is some months old, but as it received no replies, may I resurrect it?
A very good, free gear program is GearDXF (
http://www.forestmoon.com/Software/GearDXF/). It understands both world units and freedom units. It can produce 2D dxfs and can extrude them into STL files for 3DP. No connection other than a long time user.

In a slightly different gear direction, does anyone know of an accurate reference or program for designing cycloidal gears as used in clocks? Cycloidal gears are different in form from involute gears. My friend is back to his long-term want to build a clock and would like to find software that does this. His printed references do not agree with each other so he would like a definitive answer.
Any help would be appreciated.
TIA

My friend says thank you very much. He looked a lot on YouTube but didn't do a Google search.
I'll let you know if it works for his project.
Thanks again for the links.
