First you can go from Carrara to Amapi using the obj exporter. This will work pretty well if you want to edit an object from Carrara into Amapi.

The main reason why we there is no importer of Carrara file format is that it is not very useful. You want to use Amapi to model objects for Carrara and not the contrary !

What the update button allows you to do is to update changes to an object after your modified it in Amapi, without loosing your Carrara shader or the position or the instancing.

A simple example: if you model a colum in Amapi, you can use it to model a temple in Carrara with 50 instances of that column. You can then edit your column in Amapi 7 and save it to the same file. When you click on the update button, the 50 instances of the column will be updated all at once.
