Getting the perfect fitment with sheet metal could make you look like a king or queen among designers and friends with the welder/fitters. They shall dance and sing to the all Supreme of sheet metal miters…. Although SOLIDWORKS Miter (mitre) Flange is a command that doesn’t seem hard, there are some hidden challenges which I will demonstrate below.
SOLIDWORKS Miter Example
I have a simple flat sheet metal part that I want a miter flange on. Selecting the command and then selecting the face I want to start on comes to our first challenge.
I created my sketch on the orange face and adding in my desired profile. It is fully defined with all the dimensions and relations I need.
Hopping back up to my sheet metal tab because miter flange is a command we can go directly into without leaving the sketch, we then select it.
When I select my edges and try to complete the command I get an error saying “Unable to make a miter flange”. Why is that?
It turns out that SOLIDWORKS does not like a miter flange with a horizontal line coming off the edge. Editing that sketch and making that line 30 degrees and adding the miter flange we can now see a preview. When I teach I typically say, “If you see a preview when using your command, it should work”.
I want to move onto the flat pattern after fixing my sketch to what I want and complete my miter.
SOLIDWORKS looks for the easy way out with these particular bends. When editing the flat pattern we notice that Simplify Bends is turned on. This works great for basic boxes and straight cuts but not so great with rounded edges.
You can see the before and after above. Your welder and fitter will thank you for the more precise corners. The “s” shape is realistic after bending producing betting fitments.
