Both the individual weldment profile files and the single configurable weldment profiles for aluminum I-beams show some sizes that I cannot find in any source. For example, there is a 2.5 x 0.923 LB/FT model. I can find no evidence that such a beam exists. The 2020 Aluminum Design Manual from the Aluminum Association shows only 16 beam sizes, and 2.5 x 0.923 isn’t one of them. Ditto for the 2005 design manual.
The single file and configured models show 40 beam sizes.
Does anyone know where this extra data is coming from?
Just curious: are those profiles the SW default ones? we use only customized weldments so I really never noticed how SW is supposed to handle them out of the box.
In our field I noticed that some company have some special size variation for profiles depending on the material, not according to some national standard just theirs.
I’ve always viewed any of the preroll detail data like profiles, holes, tap drills, like Reagan viewed the Soviets - Trust but verify. Most of it’s pretty good, but some is little better than lorem ipsum to show you the format that the real data should be in…
I agree. I did download and save the profiles in SW back when I was first starting, but since then I have come to the conclusion that some of them were created by people on their second day of using SW, with very little instruction beforehand (and yes, I have fixed those).
I don’t use aluminum and thought I would google it. Seems to me that they have a completely different callout than steel. https://www.metalsdepot.com/aluminum-products/aluminum-beams
I have found problems with Supplied models in the Routing package, The next release did have models fixed.
I see what they have done. The weldment profile has combined beams form several different standards because they have the same geometry. Of the 40 beam sizes in the file, 15 match sizes from the Aluminum Association standard, 12 match sizes from the Canadian standard and 4 match sizes from the Canadian wide flange standard. The remaining 9 sizes are still a mystery, and some of them are strange. I’ve never seen an I-beam profile with a fractional depth, but there is a 2.5x0.923 section in the file.
I’m just going to rearrange things to match the Aluminum Association 2020 tables and delete the oddballs.
