Beams with miters

[GeomGym]

Is it possible to create a miter cut on a beam?   Of course revit can automatically determine a solution for this, but I'd like to be able to over ride this.

From the user interface it's possible to cut steel beams with a reference plane. To do the same from the API would be a good start.

Thanks,

Jon

I searched for API to cut a steal beam by a reference plane. We know it can be done in UI. However, this functionality is not exposed in API. Only your option currently to have a miter cut on a beam is to use InstanceVoidCutUtils.AddInstanceVoidCut method with an unattached void in a family instance. You can find Jeremy’s blog post http://thebuildingcoder.typepad.com/blog/2011/06/boolean-operations-and-instancevoidcututils.html which is explaining AddInstanceVoidCut method (along with other geometory related operations) with sample code and a sample void cutter family. This sample is for walls. The similar code snippet for beams is in the AddInstanceVoidCut method page in the API reference. Please note that the unattached void can be fully selectable by users.
