Hi Gary thanks for posting in the Lucid Community! While Lucidchart doesn't currently support a flowchart template specifically for metal fabrication it does have a very large number of other flowchart templates that likely could be customized for your needs. I recommend taking a look at the Lucidchart template gallery under the "Build flowcharts" section to view them.

I'd love to hear from the broader community if anyone else has experience with this type of diagramming! Finally if you'd like to request a specific metal fabrication template you can do so using this feature request form. Please let me know if you have any additional questions.
