What do you use multibody sheet metal models for? Pems? Weldments? Do you create drawings of multiple flattened parts? Do you eventually merge the bodies? How useful do you find these techniques?
i use multibody when the part im trying to build won't fit on a standard piece of metal such as a 6x12x.125 . i use this feature to allow me to have a complete structure of a face before an assembly, that way when i add it to an assembly the parts still has attributes a part.
weldments, concept assemblies (no drawings)
I generally don't do multibody for sheet metal. Instead, we do assemblies.
For PEM'd parts, it's an assembly and the base metal under one part number in the same drawing (multiple sheets) and routed as one part through the shop.
I have used multibody sheet metal for some liquid tanks with odd angles and mupitable bend angles. I used a hybrid modeling technique to develop a solid body with desired shape, then copy body mupitable times for number of panels, offset face of required body for desired overlap, and then used convert to sheet metal for the different bodys/panels.
The modeling method works and updates adequate, but I would sometimes fight, the different flat pattern configuration instances suppressing and unsuppressing, and getting flat patterns onto drawing sheet.
The attached example is a quick model, many details need fine tuning before using to manufacture.
We use multi-body sheet metal parts in weldments. Pems (and other items) if in both as welded and as machined (although I am trying to get our users to turn off as welded when both configs are the same) are inserted parts otherwise I encourage to insert weldment into assembly and add those items in assembly. We use to create multiple flat patterned views in drawings (make sure you have link display states to configs checked otherwise you may end up with blank views in your model and drawings in SW2016 anyway) but since our outside vendors use different tooling no way they were correct for everyone so we stopped making flat views on all bent sheet metal parts. We do not merge bodies. Not sure what you mean by your techniques question. One of our bigger issues is spinning off sheet metal parts created before SW2013 (if you are familiar with the changes to sheet metal made in that release you will not need to ask any why questions).
