Hi @mikeJFCS6,

Welcome to the Fusion 360 community!

I am sorry to hear you are having this as exporting in STEP!  To try recreating this behavior and take a closer look at it on my system,

would you mind sharing a public link (see this web page) to the model file with me, by posting it in this thread or by sending it to me via PM?

I would also appreciate your letting me know if this happens on a particular file or all files.

If you have any questions, please let me know - I am happy to assist you!

Thanks,
