Software advice on fitting an orifice within a cylinder

[JD_PM]

TL;DR

I'd like to get some advice on what software is best to fit an orifice within a cylinder.

I have a stp file (PF does not support it so I cannot upload it here. If there is a way I can share it please let me know) of an orifice and I want to create a new file where the orifice is fit inside a cylinder.

What software do you recommend me to use?

Thank you! :)

You can change the file extension to "txt" and upload it. Then tell people that it's an "stp" file, so they need to change the file extension before loading it into their 3-D mechanical design package.

It also helps if you save a few screenshots as JPG or PDF files and upload those too, so that others have an idea what your design looks like in your design package.
