Obsolete AISC 14 members for AS 2023

[dminor]

I opened a model in AS 2023 that was created in AS 2018.  The model is big and all members are now obsolete AISC 14 sections.  Is there a way to update all members to AISC 15 globally or thru the Management Tools

hi, 
so the obsoleted the Section Class,   the section names are the same,   one assumes they did this to meet the new AISC Section standards  published on the AISC website. 
One would assume that they have updated the parameters of the various profiles to meet this new AISC15 Standard. 

you could try the Model browser,  check edit properties , you can set sort by single part ,   also the 'object Name' column   you can click in the header of the and the sections will sort  grouping same type together. 

you can then select multiple lines with shift key function and then  Select into the object name cell and browse to the New Section Class and set size.

seemed to work in this small test.

Thanks John.  Your method is quicker than selecting each part in the model, but it still has to be done individually.  I was hoping there was a way to set the AISC version globally through the Management Tools or another application.

These zzzobsolete classes are one of the most frustrating AS things to deal with. If the shapes are obsolete, why do structual engineers/designers continue to use them on a daily basis ???

In my line of work I am always dealing with existing structure I am trying to tie into, modify, or replace.  Often built back in the 1940's or earlier.  I've have had to create several dozen shapes from the ASD7 version of steel shapes and use them on a regular basis.  I've always wished for someone create a library of these Historic shapes that could be downloaded.  Maybe there's not much demand for that , but it sure would have saved me a bunch of time over the years.
