Railing Path

Anonymous — Fri, 10 Apr 2015 18:56:15 GMT

Hi,

I'm wondering if Revit API allows edit the path of existing railing elements.

Please let me know if there's any way to implement this or any workaround.

Thank you for your help in advance.

Dear Jinsol, As far as I know, there is no such API.

Put aside accessing an existing railing path, is it possible to create railings (ie new path) via the api?

Can we have mouse events in Revit APIs. I want to create addins which allows me to draw line using mouse.

Ok, lazy me...

Help file:

private void CreateRailing(Document document, Stairs stairs)
{
    Transaction trans = new Transaction(document, "Create Railings");
    trans.Start();

    // Delete existing railings
    ICollection<ElementId> railingIds = stairs.GetAssociatedRailings();
    foreach (ElementId railingId in railingIds)
    {
        document.Delete(railingId);
    }
    // Find RailingType
    FilteredElementCollector collector = new FilteredElementCollector(document);
    ICollection<ElementId> RailingTypeIds = collector.OfClass(typeof(RailingType)).ToElementIds();
    Railing.Create(document, stairs.Id, RailingTypeIds.First(), RailingPlacementPosition.Treads);
    trans.Commit();
}

I just need to confirm that I can create standalone in the absence of stairs. Dale

Ok, it appears that Railings require an existing Stair.

Create

Automatically creates new railings with the specified railing type on all sides of a stairs element.

Is there a suggested workaround? Invisible stairs? Dale

Sorry Mouse Events should be a new topic.

To summarise, is it possible to create railings via API without exisiting stairs (ie free-standing)? My research says no. Thanks, Dale
