Help with setting rebar layout rule

Anonymous — Sun, 10 Mar 2019 10:52:44 GMT

Revit 2018 API and versions prior had the following methods which were removed with the release of the 2019 API:

Autodesk.Revit.DB.Structure.Rebar.SetLayoutAsFixedNumber()
Autodesk.Revit.DB.Structure.Rebar.SetLayoutAsMaximumSpacing()
Autodesk.Revit.DB.Structure.Rebar.SetLayoutAsMinimumClearSpacing()
Autodesk.Revit.DB.Structure.Rebar.SetLayoutAsNumberWithSpacing()
Autodesk.Revit.DB.Structure.Rebar.SetLayoutAsSingle()

I have been trying to change the layout rule setting for a set of rebars without any success. Is there any replacement for the above mentioned methods that I do not know of? Could someone explain how one sets the layout rule for a given rebar element with Revit 2019 API?

I will be grateful for any assistance offered.

I have the same problem. Those functions are replaced to the RebarFreeFormAccessor class but I get SEHException every time if I try to use those functions.

So the free form rebar is just full of bugs. I think the api functions are not even tested once. I recreated the rebar as shape driven rebar then I called the

rebar.GetShapeDrivenAccessor()

This accessor allowed me to use the

accessor.SetLayoutAsMaximumSpacing(spacing, arrayLength, true, true, true);

function without SEHExceptions. So it is working.

hi @Anonymous

have a look at line ~400:
