Align Ceiling Grid to a wall of a room

[harilalmn1]

Hi All,

When we create a grid ceiling for a rectangular or square room using Revit API, usually it takes care to arrange the partial tiles equally distributed on either ends of the span. In that case, we don't have to do anything other than creating the ceiling. But how to handle the situation when the room is, say 'L' shaped and you have to start the grid from a particular wall? Or simply, align the grid to the wall.. Is there anything to control the model lines on the compound ceiling which defines the grid, in Revit API?

Hi.

I am not aware of any specific support for this in the Revit API. In general, if a feature is not available in the Revit product manually through the user interface, then the Revit API will not provide it either. You should therefore always research the optimal workflow and best practices to address your task at hand manually through the user interface first, before trying to address it programmatically. To do so, please discuss and analyse it with an experienced application engineer, product usage expert, or product support. Once you have got that part sorted out, it is time to step up into the programming environment. I hope this clarifies.

That said, I see one blog post on aligning a slightly off-axis grid that is vaguely related to your question and does illustrate some API functionality that might come in useful:

Possibly even more useful, this short note on moving a grid:

I hope this helps. Good luck, and please share your final solution, in case others encounter the same requirement.

Thank you!

Thankyou Jeremy for the guidance. I will check if anything from these would be useful for me to resolve the issue...
