That big curvy arrow button isn't a download button - it is a drag into Archicad button.
Click it and drag it onto the Archicad icon at the bottom of your screen (Archicad must be running of course) and wait for Archicad to open, then continue dragging onto the floor plan window.
Or you can go into the object settings and browse for "Lift" or whatever key word you want to use and wait for the BIMComponent object to show in the list.
Then you will have a download button.
Thought I had better try this.
Works fine both ways in Archicad 18.
Comes up with a "Serious error during download" message when I try either method in version 19.

Thanks Barry now it works.When i open the object all parameters come with a ? mark.Is it because i'm on Mac or is it because i opened it in AC17? Can i edit the object? say remove one cabin and have only one?
Thank you for your help.
