Sheet Metal Assemblies differences from a regular assembly

[Dianmarr]

Hello,
I was asked a specific question on an interview as to whether or not I have done assemblies with a lot of sheet metal parts. I am currious as to why he might ask this, I have worked with many sheet metal parts adding them into assemblies with other extruded parts but not solely sheet metal parts. I also have been working with Pro/engineer for 12 years... so I am experienced. What am I not reading between the lines with this question?

Wondering if it might be a 'Pro E' specific question (which I kinda doubt) or if he is asking whether you know how to do sheet metal assemblies in general...

Hi Wogz,
I had just taken and passed their sheet metal test. Is there a difference in sheetmetal assemblies and regular assemblies in Pro/e? I have always used sheet metal to create my parts then added them to my assemblies. Your thoughts are appreciated.
Thanks

There is no fundamental difference in a sheetmetal part vs a standard part in Pro/E or Creo.

There are some differences between sheetmetal PARTS and standard parts but I don't see any difference between ASSEMBLIES with sheetmetal parts and any other assembly.

I guess I neglected to put "in assemblies" in my reply.

I know my current & previous bosses have asked if I can design in Sheet metal, meaning, knowing bends & bend radii, tabs, PEMs, corner overlaps, what the flat pattern will look like, how to economise parts per / nested on sheet, safe parts vs. pointy sharp cornered parts, etc... Wondering if this is what he was after.. (Which is what I was referring to)..

I've seen one co-worker expect a ±0.01 tolerance over 7 bends.. And others who design a part such as a square tube (4 bends) and expect a 0" gap at the seam.. Perforating a sheet with a billion holes and not expect any stretch.. Or little lip bends that require sacrificial material, either designed in the part to be removed later, or a secondary piece used to hold / back the part while in the brake..
