AISC 14.1 folder

What is the AISC 14.1 folder for?

When I created a schedule the Wide Flange were not showing weights if the type was from the AISC folder, but if the beam was entered using the family where the AISC folder is located called "W-Wide Flange" the weights would show on the schedule.

Just trying to understand what it is for when it wont show weights.

Have you reviewed the family whether it has the weight as parameter?

do you have a sample? a model with two beams, one for each case?

Thanks!

Where would I look that up at?

Even if it did a have a weight and worked, why use the families in the AISC 14.1 folder over the others?

See attached model with two beams, I also made a schedule that shows only one has the weight.

there are two kind of column/beam structural families in Revit content:

Standard structural steel element. The Section Shape type property of a steel framing element specifies a section shape. A defined set of Structural Section Geometry parameters exists for the element.
Custom steel element. The Section Shape type property of a steel framing element is Not Defined. The geometry parameters required for generating steel connections are not defined.

(source: https://knowledge.autodesk.com/support/revit-products/learn-explore/caas/CloudHelp/cloudhelp/2018/ENU/Revit-AddIns/files/GUID-6244E741-5D14-4DAD-AE25-5069F71B69F3-htm.html)

Each have a different parameter for weight:

- Custom steel element - W - it is nominal weight/foot. Can be used in schedule

- Standard structural steel element - doesn't have a weight parameter that can be added to schedules. It has the Nominal Weight type parameter.

Weight parameter (not to be confused with the Nominal Weight from element type parameters list) can be used in schedule just in the case when the steel fabrication data is attached to the beam. In this case, in the schedule, the value takes into consideration the cuts made by holes or bolts, but considers the cuts made with steel modifiers. It is a read-only value.

(for more details about steel fabrication shape you can fin here: https://knowledge.autodesk.com/support/revit-products/learn-explore/caas/CloudHelp/cloudhelp/2018/ENU/Revit-AddIns/files/GUID-6244E741-5D14-4DAD-AE25-5069F71B69F3-htm.html)

(more info about how to calculate the exact weight for the custom families can be found here: https://knowledge.autodesk.com/support/revit-products/learn-explore/caas/sfdcarticles/sfdcarticles/Scheduling-weight-parameter-of-steel-columns.html)

Okay, I am not picking this up yet, so if I understand correctly.

If I want to use the weight in the schedule I cannot use the AISC 14.1 families, is that correct?

for AISC 14.1 you can schedule the weight parameter by creating a shared parameter and adding it to the schedule.

see steps here: https://knowledge.autodesk.com/support/revit-products/learn-explore/caas/sfdcarticles/sfdcarticles/Scheduling-weight-parameter-of-steel-columns.html?_ga=2.153757488.94283502.1561958560-1146509996.1555334485

then, if you want to have the weight on the same column in schedule for both families, use Combine Parameters option:
