Ceiling Grid Pro R1 ArchiCAD Object-How to use this object?

[Anonymous]

CeilingGridProR1

I have used this object in the past and have found it to be an excellent object to generation suspended ceiling grids. But today I need to use it again and for the life of me I can't remember how to set up the object. Under the parameters it mentions the roof tool and having a pitch of 0 degrees.
I have done a quick search on the internet, youtube and this forum looking for a tutorial on how to use it.
Any help on the use (step by step) would be greatly appreciated.

Is it a case of placing a 0° roof in the shape of the ceiling you want and then (while it is selected) using the "roof accessory" to apply the ceiling object?

Thanks Barry,

I had not installed the accessories add-on which was missed after the install of ArchiCAD 16. My bad.

Hi All,

I am using the ceiling pro tool with a 600 grid however the last tile is elongating out larger than 600 (please see attached plan view orange dotted line is where the next ceiling grid tile should begin - also demonstrated by the little hot spots).

Is this a common issue? Can anyone please explain why this is happening and how I can correct it?

Thanks for your time and attention,
