ArchiCad to LIRA-SAPR structures

[Anonymous]

LIRA-SAPR program provides the ability to import ArciCad model (*. mdb). Please tell me how I can keep the model in the following ArciCad file extension?

[Laszlo Nagy]

There is no MDB file extension in all of ArchiCAD.
Were did you get this information that ArchiCAD has such a file extension?

I understand that there is no such file extension in ArchiCad directly. My question is-how do I export (or otherwise modified) a model from the (*. pln) to (*. mdb).
