shift1313 Posted September 6, 2008 Share Posted September 6, 2008 you need more info about the sprocket(follow the excellent link remark posted). what pitch chain are you running. You will basically need to draw one tooth and do a polar array(command ARRAY). In the array dialog you you will have option for polar or rectangular, you want polar. you will need to select all the lines you want to array, your rotation point, and the number or copies. there is also a selection for rotate while copying( i dont remember the exact terminology) but you will need that checked(default is checked i believe).

ReMark Posted November 19, 2010 Share Posted November 19, 2010 i used that before that remark posted and it doesnt work We'd be more than happy for you to share with us something, that in your opinion, does work. Please provide the necessary information in your next post. Thank you. BTW...the link I provided depicts how to draw up one tooth of a sprocket. Once you have done that it is up to you to create the full sprocket using the Array command. Of course you have to have some idea of the type of sprocket you want to create and have at hand all the pertinent dimensions otherwise you're designing in the dark without a clue.

ReMark Posted November 23, 2010 Share Posted November 23, 2010 You're welcomed. Glad to hear you found a solution to your problem. By the way, the correct terminology would be lisp routines not scripts. Quote Link to comment Share on other sites More sharing options...
