Rebar Weight Filter

[BrentBurgess1980]

As part of our Safety in Design, we would like to highlight bars using filters to show bar sets where the average weight of the bar exceeds a certain weight value (i.e. 100kg).

For example:

Total Bar Volume = 0.352 m3

Number of bars = 24

m3/bar = 0.01466

Density of steel = 7850 kg/m3

kg/bar = 115kg

Is this possible with the current filtering parameters to achieve this?

Thanks,

Brent

To my knowledge, you cant make formulas in filters and the Weight is not a parameter option in the rebar. depending on the version your using, you can only use And/Or statements. 

Off the top of my head... To do this I think you would need to edit the rebar family to add some Shared Parameters to do the calculations.  You can use the parameters with/in formulas in the family to do the calculations.

• Length Bar Diameter and Quantity are definitely existing parameters
  • use them to make a calculated parameter for the rebar volume/area
• add another Calculated Parameter to calculate and display the Volume/Area times the assigned weight. 
  • you could also make another shared parameter that can be an instance or type parameter to assign the weight manually.

**Another option for the parameters would be to make a rebar schedule and add the parameters to the schedule. when you add a parameter to a schedule, it gets applied to the elements of the category of the schedule.  I believe in 2023, they added an option when adding a parameter to "Add to all elements in category" that would need to be checked. then you can use those parameters in the filter.

Then you can use the schedule for validation. you can use Conditional Formats to highlight things in the schedule. you can also select items in the schedule and use the Highlight in Model tool to find the items.

i hope that all made sense 😁.

I was able to write some code to add a parameter to the rebar, and add the value I need so I can filter.
