Select by IFC field value

[Stig Runar]

Hi!

 

How can i select objects based on a field value?

I want to select all IFC Objects containing the IfcPlate Name HULLDEKKE.

Hei Stig Runar!

I would try to set up a worksheet, searching for IFC and field values 

You would get a rows for every item and could the right-click each row to select the item.

That was a good solution! Only downside was that you can only select one line at a time.. Or is there an other solution?

There might be a possibility to use the Data Manager and assign a class or record to every HULLDEKKE to make it simpler to isolate or select them. I have only limited experience with the Data Manager so I can't really help

I'm guessing it's possible to write a SelectObj() script that would select every HULLDEKKE object in one go but my quick + very feeble attempt didn't work 🙂

I don't believe there is a way to use IFC field values as part of a Criteria.

 

This script will look at every IFCPlate in the file and only select the ones that have the name entered in the dialog box.  Comment out the StrDialog line to suppress the dialog box and always look for 'HULLDEKKE' or whatever other name you put into the MyName variable.
