I am about to publish my first custom structural shape for use in Frame Generator and using the Frame Analysis tools. This custom part is currently authored as a table driven iPart. It would appear from a search that FA will still not calculate all of the required section properties needed for a hollow section, which is a future bummer for me, but becuase this current shape isn't hollow I might be okay on this first one. I have a few questions about this authoring process:
1.) When publishing the structural shape it will ask me for a Standard Organization and a Standard. My shape is bent from a light gage plate material covered by ASTM A1011/A1011M-12B but isn't a standard structural shape. My Mastering Inventor book (Curtis, if you're out there buddy, this part of the book could use further development) says that if I leave the Standard Organization field blank, the category selection will be "Unknown". That's all it says.
a. Does this mean there would be an issue using or selecting the part?
b. Should I list ANSI as the Standard Organization even though this shape technically isn't covered, the material is?
c. Can I enter a Standard in the field or is this a drop down list only?
d. If I can only select from a pre-determined list, what do I select for the shape?
e. If I leave all of this stuff blank because it is not governed by a particular standard will this affect the performace of the parts?
2.) When I publish the part the wizard will ask me to map section properties from the parameters to the drop down lists in the wizard.
a. How do I enter user parameters into the iPart file/table that match the units formatting for the properties (e.g. 5.46in^4, 2.36in^2, etc.)?
b. If I don't have (or don't need) certain parameters available during the authoring process, how will I know the part will still function properly using the beam/column calculators and frame analysis tools?
c. Is there a list of which parameters are required for which tools (e.g. the Frame Analysis doesn't use any of them, the beam-column calculator will use some of them, what uses the Section Designation parameter, what uses the Shape Width parameter, etc.)?
My apologies for the long post but I am trying to thoroughly understand this process becuase I need to do this a few times and I don't want to screw anything up and I certainly don't want to waste a bunch of time doing this several times to fix all my mistakes.
Thanks for the help!
Okay, after some more research, I have found a couple answers to some of my questions. I found another tutorial/blog post from Mark Flaylor (thanks again for your help), but this one was about custom notching. It didn't specifically answer some of my questions but the way Mark illustrated his workflow it indirectly takes care of some of the items on the list.
He manually types in the standard information and creates his own so I am going to do that. That effectively takes care of my question 1, parts a through e. I will use the ANSI standard governing the material and create my own custom standard based on the manufacturer's information.
I would still love any information y'all can offer on the second question on my list. In every tutorial/youtube video/blog post I can find, they all skip that part and don't enter any information. I understand that it shouldn't matter for the Frame Analysis tools, but what else uses this information that everyone is skipping?
Sorry for the long posts, I realize that is likely why I haven't seen any responses. Thank you all in advance for your time.
Oh, and I found the Mark Flayler blog post here if anyone else comes across this post.
Okay, it's already a good day because I learned something new this morning. I found an answer to question 2a through trial and error. I didn't know that you could enter exponents in the unit/type column in the parameter window. That made the units work for my parameter matching. I thought my only options were the ones in the list (I always thought it was funny that the only unit type for area was circular mils ).
Anyway, that takes care of most of my questions. Really the only things left on the list are 2b & 2c which can be summarized by the following:
How do I know which parts of the program use which parameter mapping? So I can tell which areas are affected by my inputs. Is it just the beam/column calculators or what?
In every single tutorial I have seen, the presenter skips over the parameter mapping (except length) as though it is of no importance. Is that because it really isof no importance or because they didn't need it?
Okay, I guess I've either stumped the experts here, was too lengthy in my explanations, or this really isof no importance and I shouldn't bother with it.
Where's Hugh when you need him? On Christmas sabbatical I imagine? Wait, did I just use sabbatical and Christmas in the same sentence...
I was under the impression that those other numbers don't do anything and Inventor calculates them from the actual physical model.
The help on this within Inventor is ridiculous. I consider myself an expert and have done extensive CC editing in the past which was also horrible.
What happens when you use published FG parts. I get them all wrapped into one because the part number does not include length. I also get other issues with the BOM with these. Sorry to hijack this thread but maybe somebody could explain how to get the part number to appear like the other structural steel parts in FG. Does the original part have to be an Ipart? I have seen a pdf on this by cadmanto which I might have to use although I was hoping it was not going to be that complicated.
Yeah, the part number thing is not an issue for us here because all of our part numbers are edited after the fact to a project specific/date specific number. Once we are done with the frame modeling, the BOM for the assembly is given a "once over" where all of the part numbers are defined there based off of the Mass property and some user defined stuff.
I agree, the help is not helpful in this area and every single presenter/youtube/blog segment just skips over them. One of the AD guys in his tutorial says "I'm gonna skip over all of these, I could tell you what these all mean and what they're for but they shouldn't matter for publishing the part"... Shouldn't matter to who? They might matter to me! I don't have any idea if they matter because I don't know their use.
I have published the part but I haven't used it or analyzed a frame with it yet. I'm still working out some CC/FG bugs before I go crazy publishing everything I need to do.
No one responded to my Custom Notch post... I'm gonna resurrect that one too.

Here's some stuff I have been using for a while from some helpful guys here on the forum. Curtis if you're out there you need to write a book just on this frame generator stuff!
