Wall Opening

[Anonymous]

Hi,

I'm using the Revit 2014 API ad I'm trying to create a non-rectangular wall opening.  

The documentation for Create.NewOpening suggests that making the opening with an iList<Curve> is only applicable to roofs, floors and ceilings. When I try to use one NewOpening(element wall, Ilist,Curve> profile, bool perpendicularFace)  method I get the InvalidOperation crash.

The only mention of wall openings is in the NewOpening(Wall, XYZ,XYZ) overload which is for rectangular openings. I have been able to use this successfully.

Any help would be most appreciated.

Dear Martyo,

Here are rather old posts which may contains ome hints:

The command CmdCreateGableWall defined by the latter is available for Revit 2014 too, in The Building Coder samples:

Dear Martyo,

To create a non-rectangle on wall, you have to create a window family instance, which doesn't have the window frame. It can cut a hole in the wall. You can define the shape of the window to any shape. So in this way you can create any shape of opening on the wall. Windows can be created by calling NewFamilyInstance() method.

On how to create such a window family, you can refer to an family called *Window-Round Opening.rfa in revit's default family library.
