Tube coping not working correctly

crectorC6Z3M — Mon, 24 Nov 2025 01:13:44 GMT

Hello, I am new to fusion and I am working on tube coping. I have watched several videos that show splitting the one tube body with the other tube body. then they select the inside of the split body and press/pull the wall thickness and it subtracts the split section. Sounds simple however, I get an error when trying to subtract the tube wall thickness. I can subtract .001 less than the wall and I don't get an error but it also doesn't subtract the section either.

can the current version for fusion subtract body?

I cant select select the inside of the tube to split the tube body. It selects the entire tube, not inside or outside.

Thanks for any help

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

And provide the link to the tutorial.

It doesn't matter what version you have...

you go to File>Export

Then you click on the ... to select the Exact Location on your hard drive that you want to place the file so that you know Exactly where it is...

Simply Remove the Split Body.

Click on the image above to enlarge the view.

Alternatively, you could have done and Extrude-Cut with the sketch circle.

Reading your problem description again - not sure what you really really want, but rest assured it will be easy.

I am trying to make a cut on a plasma table that looks like what this guy did in this video. He split bodies using the inside surface and used push/pull to subtract the inside cut to the outer surface. pretty cool but I can't select the inside surface to make the split and further I can't subtract anything using the push/pull. Anytime I subtract the full thickness of the tube I get an error.

Can you post the link here so that I don't have to type it in from your image?

See Attached.

Do you need a Flat Pattern for your plasma table?

Yes, that is what I need. My plasma cuts periductular to the surface of the tube.

I didn't quite follow the surface offset and thicken but I am trying. I am new to this fusion thing but, I am learning. I have a bigger project I am working on but, I think if I can learn the basics my other questions may be solved.

Thank you for the help

I spent some time studying the file you sent. I was able to create an offset face from the inside profile and thicken it into a new body. I then split the pipe, convert to sheet metal and create a flat pattern. This is exactly what I was looking to do! Thank you very much!

I still don't know why I can't use push/pull to remove a section. If my wall thickness is .05 I can push/pull .049 but if I try .050 I get an error. I am confused, as I see a lot of videos showing push/pull to subtract a section by push/pull the full thickness.

Do you have a tube attachment for your table?

Yes I do and it does pretty well. It's a little slow to load material in it but it makes complex cuts a breeze.
