BOBL thanks for that , I get that far with GT but can't save as dxf if you can get it to please send me the file as I need to make a gear yesterday:>)  Dan Keith

BOBL, I forgot to mention upon opening GT I get this notice.  Dan

Hi:

  Hmm, that error usually indicates a video card driver thats old,..or a video card thats very old.
Does the program run after that error?

Art, yes it does and as I said I can generate the 250 tooth gear but can't get a dxf file.  Dan

Dan:

  Hmph, generates fine foe me too. What module or dp did you need, Ill drop the dxf here for you. Did you ask Bob for a new license just in case yours is corrupted?

Art

Dan;

I also encountered a problem when I tried to export your dxf, what I got was only half the gear... Weird..  Maybe Art can shed some light of perhaps why that is?


Cheers
Bob

Dan;

I tried sending your license, however got an error from my mail server saying message cannot be delivered to the following recipients:
Reason: Illegal host/domain name found... Can you contact me offline so I can get this off to you..

Cheers
Bob

Art, I am making a drive for a solar heliostat and need a four foot dia. half gear with small teeth about 1/4 or 3/8 inch nothing critical. Also about a 2 inch or so pinon, again nothing critical. Thanks Dan

Ill leave the pinion to you as I ditn see tooth cnt..but heres a dxf of a mod5 245 tooth radius of 2foot
so 4' dia. Seems to work fine here. Youll notice at that size the teeth are basically pressure angled
straight teeth..thats normal as the radius to tooth ratio is very very high..

Art

Thanks Art that will get me started. I salvaged several hundred high quality laminated mirrors ,4'x4' from left overs from a large array solar project and need to do something with them, so I will be making some gears to track the sun, haven't nailed down a design yet but I will post pictures as I proceed.  You need a heliostat to shine some light on your projects:>) Thanks a lot Dan
