[SOLVED] Property missing

ReignBough — Tue, 06 Dec 2022 13:04:02 GMT

Assuming that there is initially no property on Property Manager.

Create a property on Property Manager.
Export the created property.
Create a scheme/schedule with criteria of the created property.
Delete the create property on Property Manager.
Import the exported property.
Open schedule. The criteria (with property) is now "Missing".

~~Why?~~

This is not a developer question, but here it goes:

When you export a property in a schedule to Excel, there is a hidden column with the internal Property ID.

When you delete the Property, it is gone together with the ID.

When you re-import the schedule, ARCHICAD cannot map this property to something that doesn't exist anymore.

If you try to re-create the property, it'll have a different internal ID. So it is lost forever.

You may be able to export your properties to XML, edit the XML to re-enter the old guid and re-import the properties from the XML to re-create the same guid.

Thanks stefan.

I am trying to create add-on that uses the property. I saved the GUID of the property on a file. I did the process above except that the scheme is the file I created. That's why I found that this is happening on the scheme.

I already created a work around with this problem.

Hello,
Any improvement on that?
"You may be able to export your properties to XML, edit the XML to re-enter the old guid and re-import the properties from the XML to re-create the same guid."
Thanks
