Showing a Gasket in an Assembly

I have a specific closed cell sponge neoprene gasket that we use many places in our assemblies. The current drawing (in Unigraphics) shows a profile and a table of "cut" lengths. If I make this same drawing in Solidworks and show the same table how can show the shape (example: around an opening in a piece of sheet metal) of the gasket as it applies to different applications? I don't really want to make multiple configurations.

TIA

Steve

Will the drawing be referencing a part or assembly file?

Are you mainly looking for a tricky way to do it w/o configs but have a table auto filled?

Maybe a screen shot of the UG drawing?

  I want to move away from the table all together and make manufacturing cut as required. I only want to show the position of the gasket in the assembly.

    Hey Steve,
    
    I would compare your gasket requirements to our requirements for foam. We purchase foam in rolls, 36" wide X 20' long.
    
    For straight forward applications, we create multiple configurations using a design table and provide all part numbers for a series of assemblies in one product line.
    
    Example: Foam wrapped around a cylinder with requirements for various diameters, lengths and sometimes thickness. In addition to the size requirements, we also provide a flat (for detail drawing) and a rolled (for assembled state) configuration for each part number.
    
    For situations where the foam is altered by being cut and/or deformed in the assembly process, we still created two configurations for a part. However, due to the complexity and specific nature of each application, only one part number/two configs are documented per database.

I've had to deal with this same situation for viton gaskets made from cord stock. At my former company the procedure was to create a new p/n and SW file for every place a new gasket profile was required. Each length/shape often got its own drawing for inventory purposes. We just made sure the material custom properties called out the right cord stock and length. This isn't much different than adding new configs to a single gasket part, but at least all the profiles are independent and there won't be a single monolithic part with 100s of configs to maintain and keep current in every assembly where the file is used.

Another, somewhat klugey, option is to model the gasket as a feature/body in a new config of the flange assembly. That way it's visible when you need it, but the geometry doesn't have to be tracked outside of its context. You can even control the position of the new gasket body so it looks right in exploded assembly views. You would then use an empty gasket stock part with a quantity of A/R (as required) everywhere the gasket material is used and callout the specific length in the assembly drawing.

  Eddie, Mahir, thanks. I didn't want to create separate config's just because with Smarteam (Eddie knows this) I'll have to create individual Profile Cards for each. I am kind of leaning towards Mahir's idea of just showing a body in-contect of the assembly and let the quantity change at the assembly level. Ed, I'm going to do this by making the Gasket an Item in Smarteam so that I can drag it into the assy BOM and then change the quantity when needed. I'll model the sketch profile and use that when I need to show the gasket.
