Intersection with Sheet Metal

[Anonymous]

Hi All, I appreciate your help. 

I am trying to make a sheet metal sheet 'half-barrel' mate with an existing tessellated dome, and I am having trouble getting the intersection to work. Essentially, I am making an igloo type construction. I have attached a crude, solid picture to explain my goal, however I will be making the piece out of sheet metal - i just have not figured out how to make it happen yet. I will be fabricating this piece, so I would like to know how to cut my rectangular sheet of metal so that after curving it, it will mate to the panelized dome. Any advise is appreciated!

Here is a file on how I did it, it might not be the best way but it got the job done.

Thank you! I will try to make another version for a slightly larger size and see if I can replicate your work.

Below is a screen cast showing the problem and one possible approach at a solution.

the reason why you attempts to use the dome as a tool to create the tunnel shape is that the edges of the dome only contact right at an edge.  (I zoomed up on that right at the beginning of the screen cast) fusion is unable to handle that condition for things like combine, boundary fill, etc.  A possible solution is to create a solid that has that little triangle sliver filled in so it's a proper body, and use that as a cutting tool.  (the rest of the screen cast is me meandering around and getting there eventually, didn't really start with a plan, sorry).  You could also create copies of the three surfaces that intersect, stitch them together, offset the thickness of your metal, and use that for your tool.

Awesome. I will give that a try as well to see if I can replicate. Thank you.

@wmhazzard and @laughingcreek , 

I dunno if it means anything, but your help allowed me to progress the project. I find it nice to see the results in real life, so sharing an update. 

Thank you

Hey, that looks good.  Is that a pizza oven?

Sure is! Couldn't have done it without the help of the good folks on this forum.
