Saved an object in AC 10 - now unusable in 9???

Anonymous — Mon, 02 Oct 2006 14:41:21 GMT

This is not good. Someone please tell me that there is a method to save objects in 10 and make them usable in 9 and vice-versa.

I don't believe there is any way to "save down" an object.... I don't believe there ever has been. I do not even know if there is any kind of hack (like Bin/Hex editing) that you could even use to sidestep this.

I hope you have a recent backup!

So do I need to develop my objects in 8.1 so that they can be used in 8.1, 9 & 10? And will they be useable in those?

That would be the safest route, yes. I have a few objects from AC6.5 that still run in AC10.... they look like a rusty truck on the lawn because they are really simple and low-powered compared to the more modern ones, but they still work.

Personally, I like the way 8.1 created text the best (not using all the RichText stuff), but I think AC9 added stretchable hotspots that are probably the most common thing I use in my objects.

Yes, you need to edit library parts the the oldest version in which they still need to be used. Once saved into a new version the only way to convert them back is to copy paste the scripts and recreate the parameters (or find a backup copy).

Thank you both for your responses. I was able to copy and paste the code back into 9 so it works in there now. I've made a backup of my '9' objects and will be far more careful in the future. Thank you.

I like to develop objects in AC 8.1. Sometimes I add AC9 and 10 stuff by using macro calls. E.g. for HOTARC2.
To downgrade is in most cases hard work. It was discussed here a few times.

There is another solution, but it requires a bit of command-line babble. ArchiCAD has a tool to convert objects to XML and back again. You can convert objects to XML from one version and then convert them back to objects of another version. Bear in mind that new GDL features in recent versions still won't work in earlier versions, but no problems if you stick to instructions which are common to all versions.

I can provide more detail if this sounds like something you might consider using.

But you will need the recent versions of the XML converter for downgrading, isn't it? The actual downloadable one will create objects for AC10 (Version 21 or 22 I guess).

There is a version of the converter for every version of ArchiCAD from 8 to 10. Each produces objects suited to its corresponding ArchiCAD version, but the XML source may have come from any other version. For example, I could convert an AC10 object to XML using the AC10 converter, and then convert the XML to an AC8 object using the AC8 converter.
