Autodesk Inventor

[#1]

I am trying to create a roller chain as part of a cad drawing of a bicyle.

I created a link of the chain (pic attached) and I am following this video to repeat it as a rectangular pattern : http://www.youtube.com/watch?v=DiBGYdbBPHo

However the links are not following the path they're supposed to - sorry I can't attach that file right now.

Anything that I should do different from the video?

Anything that you can think to point out would be helpful. I have been using inventor for a little while but I've never used the adaptive stetches or the functions thing ot a rectangular pattern that is not in the shape of a rectangle.

I think it would be virtually impossible to see where yours is going wrong without your assembly.

For information on curve driven patterns you might see this document

http://home.pct.edu/~jmather/skillsusa%20university.pdf

...then attach your assembly when you can.

this is what is looks like so far

Is there any way to make the 2 parts of the chain rotate about the pin? It's acting like it's fixed while it's not.

I am not familiar with editing image files in Inventor (but it doesn't look correct).

Attach your Inventor assembly here.

i tried attaching but i can't attach it as a zipped file and there are too many files used in the assembly to upload one by one

[#6]

i had already found that - however when i open it I don't see any chain - how do i edit it?

printscreen attached

There should only be 3 files.

the path

one link

the assembly file.

If you can't attach here then send me the assembly - jmather_at_pct_dot_edu

[#8]

why is a helpful reply gone?

I am trying to use the chain found here: http://www.cbliss.com/inventor/Parts.htm

What other values shoul I edit in the excel sheet, anyone knows?

[#9 · Accepted solution]

You need to drag the end of part marked all the way down. Then the chain will be there.

Yes it worked!

Thank you.
