Calculate Gasket Size

[glencandle]

I've designed my part to have a 1/8" thick gasket (below).  I would like to buy a stock size from a manufacturer as opposed to having a custom gasket made. 

But I don't know how to calculate the diameter of the gasket I would need, based on the size of the square shape it assumes when on my part. 

I was hoping that Fusion would tell me the length of the tube using the Measure tool but alas it doesn't appear to be possible.  Am I going to have to do some math here?

Would love some suggestions/advice, thanks.

UPDATE: Project File attached

If this is a Sweep, you can measure the path for its length.  Attach your model and the Forum users will show you the process.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

Thanks John.  It is a sweep.  I tried to figure out how to measure the path but I couldn't.

I've updated the original post with the project file.  Looking forward to seeing a solution, thanks!

Although the measure tool will not let you measure a chain of curves the measure tool bottom right of the screen will give the length of a chain of curves or edges. So just make the sketch visible then double click on a curve to select the chain.

Wow thanks for that, I had no idea about this useful tool!

Thanks so much for this.  I love both solutions to this problem but this one feels more concise so I'm marking it as the solution.  I love this community, I almost always get sorted. 

Cheers.
