Sheet Metal Thicknesses

[rpasko]

When creating the first wall of a sheet metal part is there a way to add a specific set of thicknesses into the drop down menu? Currently it just has 0.05 as a default. I would like 20ga (.039) as default and be able to pick 18, 16, 14 & 11 ga.

Regan Pesko,



I am pretty sure that there is a "default sheet metal thickness." Of course
this would only be one value for your list. I do believe that you can set
your options to define what this default will be.

Could you use a restricted parameter list to control this?

Andy,



There may be something to that. If you introduced a new parameter and
established acceptable values for that parameter's input, that would provide
you with values that you could select. It seems like a shot in the dark
though.

You can set your default sheetmetal part thickness in your sheetmetal template part under File, Prepare, Model Properties. Not sure how to get the list you described or even if it's possible

Thanks Mike, that'll at least get the .039 (20ga) set as default.

As Andy mentioned you can use restricted values and there is a video on YouTube that shows you how to create the necessary file and update files created prior. Go toYouTube and look for "How to preset and restrict attribute values in Creo Parametric - EAC Tip of the Week".

Metal gage is not a preferred method to specify thickness, even though it is commonly listed.

The thickness associated with a particular gage value changes with the material specified. 22ga aluminum is not the same thickness as 22ga steel, and is not the same as 22ga zinc coated steel.

"Manufacturers' Standard Gauge for Sheet Steel is based on an average weight of 41.82 lb (18.96 kg) per square foot per inch thick. Gauge is defined differently for ferrous (iron-based) and non-ferrous metals (e.g., aluminium and brass)" http://en.wikipedia.org/wiki/Sheet_metal

It's not linear and it's not uniform across metals. It's a measure of weight, not thickness.

It can't be delivered by a simple list of numbers.

David,



Those are very good points.

Just to make things even more complicated, I don't think that is the case in the UK. Our 'Standard Wire Gauge' (SWG) defines a specific dimension. 16SWG is always 1.6mm, near enough, 12SWG is always 3mm, near enough, etc.
Nothing is ever simple, except me on some days...

Wire gauges are completely different than sheet metal gauges.  I concurr that sheet metal gauges are industry/material specific.  I see no problem with specifying the sheet metal gauge on a drawing since that is how you are going to buy the raw material but you are going to have to give Pro/E a thickness dimension.  I suppose you could submit an enhancement request to PTC to allow "sheetmetal tables" like the hole tables that would let you pick a material and then a gauge.

Most tables and charts will define an allowable range of thickneses for each gage and material, the delivered materials will routinely be toward the lower end of that range so they can produce and sell more sheets.

Previously I've written relations which would set the models thickness accourding to gage and material in order to account for the varying thicknesses of the different materials.
