Possible to save as 18 from 20?

[Anonymous]

I cannot render in 20, which I desperately need to be able to, after not being able to figure out the issue, I need to somehow save to 18 (the other version I have installed on PC) however when going to Save As, it only gives me the option to save to 19?

Is it possible to save my 20 file to an 18 file?

Only by saving to 19 and then opening in 19 and saving to 18.
You can only save back one version at a time.

You might be able to download 19 from the 'MyArchicad' link at the top of this forum if you don't have it.

AFAIK if you own ArchiCAD20, you should be able to install any of the previous versions available from MyArchicad.

What's not working with the render, though? Maybe we can help with figuring out the problem.
