Associatice Section Modulus

[SiW979]

One of our users has asked if it possible to record section moduli at certain sections associatively as an expression so that they don't keep having to run the command manually as they edit the model. I can't see anything within the command itself, however one of you may know a way of doing it that we dont.

Many thanks in advance

I've seen a few Knowledge Fusion (KF) examples where people have made their own "features" that show up in the tree and update as built-in features do. Perhaps a KF programmer would get just what you want.

Unfortunately, I am not a KF programmer. But, I may be able to help with a journal that would update the same expressions each time it was run. Not as automatic as a built-in feature, but better than doing them by hand each time. Would that be of any help?

Hi Jeff

Can you explain a little more how the journal would work and what we would have to do in order to set it up?

Cheers

One possible strategy that I think would work:
[ol 1]
[li]set up datum planes at the locations you want to take section values[/li]
[li]create associative intersection curve features with the datum planes and the model[/li]
[li]give the intersection curve features custom names such as "section_1", "section_2",..., "section_n"[/li]
[li]the journal will look for these named features, use the feature curves as input to the section command, and create/edit expressions with the desired section property info[/li]
[/ol]

Or, if you always want to cut a number of sections from a given csys, we could set up a named csys object as a reference for the journal then run the section command and create/edit expressions for the section properties returned.

Sounds good, if you are willing/kind enough to send me a journal, I'll try it on a part.

many thanks!

Ok, here's a test version.

Before you run it, create at least one associative intersection curve feature in your part and rename it (right click the feature in the tree and choose rename) to section_n, where n is a number. When you run the journal, it will search for intersection curve features with "section" in the name, run the section command on the feature curves, extract the area of the section, and create/update an expression named section_n_area with the section area value. Edit the model so that the section curve feature changes and run the journal again, the PMI note and the expression values will update.
