Value not in schedule

[Anonymous]

Hello Revit forum

I am having a problem, in my family-type i see the value for the nominal diameter 1 as a value. When viewing this in a schedule the value does not appear.

There are two screenshots of the project. Is there something I can add or change in the schedule to still get this value or is this a problem in the family itself? Also a "bonus" question is it possible to change the D1 parameter from a text to an integer value?

If somebody has any idea to guide me in the right direction that would be great.

It would be helpful if you could upload the family.

Sorry, did not think about it.

Does anybody want to pick this up? - I only have my ipad this afternoon so can’t open the rfa.

Meantime @Anonymous check in the field tab of the schedule properties to see if there are two different parameters with same name.

Just checked this to be sure. There are no two parameters with the same name.

It is weird because it gives the cell value for almost all the other families and on a couple it leaves the cell in the value blank but when you go check the family it has a value in the 'Nominal Diameter 1' field which does not transfer over to the schedule.

It could just be a 0.001% error where this does not work in a couple of instances but want to be sure.

Thanks for helping me.

Okay, I opened the family and can't see any obvious problems.

Loaded it in a project and it worked fine and schedule populated correctly.

The reason that I asked about fields with the same name is that sometimes you will get duplicate parameters which have come from different families, have the same name, but are not the same parameter so you can have two fields in the schedule with different values and some populated, some not.

In your schedule screenshot the families which have values populated end in SRCD whereas the one which isn't populating is a different family ending SRCL so I thought maybe they were different parameters with the same name.

Did not find anything about double parameters and names in the project concering this family. Thanks for the input.

This is just one problem. It happens with 3 types of the 100, sometimes it works and sometimes it does not. Can not find anything in Revit for a solution. Always at random can't seem to figure out what triggers this. Might stumble on the problem in a couple of weeks.

Hello @Anonymous ,

The problem lies in the Revit family in combination with your schedule.

The Duct Size of the Duct is passed through via the connected connectors of the family.

The Size parameter in the schedule of the Duct fitting always shows the nominal Duct size of the connector. And always from large to small.

The connector Radius parameter of the connector in the family is linked to a shared parameter that you can display in your schedule.

The family has 2 connectors. If you place a transition from 710 mm to 500 mm, you will see that the parameter "R1 Connector", linked to Revit connector 1, has been given the value 355 and parameter " R2 Connector", linked to connector 2, the value 250.

Nominal Diameter 1 = 2 * R1 Connector

Nominal Diameter 2 = 2 * R2 Connector

Parameter "D1 Description" and "D2 Description" are linked via a formula to parameter "Nominal Diameter 1" and parameter "Nominal Diameter 2"

If you reverse the diameters in a transition, so a transition from 500 to 710, the transition for us is exactly the same. It should basically have the same item number.

However, that is not the case for parameter ‘R1 Connector’ and ‘R2 Connector’ in this family but that is the case for parameter "D1 Description" and "D2 Description".

Schedule:

If a parameter (Field) has multiple values ​​in a schedule due to sorting, Revit leaves this field empty.

To solve your problem you need to sort on parameter "D1 Description" and "D2 Description".

If you have more Duct fitting family that do not have the "D1 Description" parameter, you need another way to sort your schedule.

Ingeger:

As for your other question to convert a text parameter to an Integer parameter, I can be brief. Unfortunately, that is not possible.

You can convert a length parameter to an integer.

You do this by adding a "Calculated Value" parameter to your schedule and dividing the parameter "Nominal Diameter 1" by 1mm.

Thanks for the reply, really appreciate it. (the screenshots especially)

I understand now what te problem is, I also talked to the provider of the families and they are also fixing this to make the families more flexible.
