Placing Pipe accessory

ameer.mansourWAK8Y — Mon, 02 Nov 2020 17:04:21 GMT

I have tried to Place Pipe accessory using Revit API

_mainDoc.Create.NewFamilyInstance(_placmentPt, familySymbol, _refDir, _mepEle, StructuralType.NonStructural); //_refDir is same direction of pipe //_mepEle is the host

but using this method is not rotating the Pipe accessory like in this video. It places the accessory perpendicular to the pipe and no way to rotate it and also it doesn't divide the pipe as shown in this picture.after placment

So how to do such behaviour using Revit API ?

I am not sure you are using the right NewFamilyInstance overload.

I am not sure that a pipe fitting has any host element at all.

This article uses a different, and simpler overload:

Maybe that will let you place the fitting in the proper orientation?

You may want to place the fitting first, before adding the pipe elements.

Here are some explorations on finding the right overload:

Please refer to the series on different ways to implement a rolling offset to see how you can choose between either inserting fittings or pipes first:

unfortunately, there is no method like this. You need cut pipe, insert instance, rotate and than connect with pipe, there is just no better way.

if (_refDir.Z != 0) { //this is what i understood from https://thebuildingcoder.typepad.com/blog/2010/08/flex-duct-start-tangent.html psfInstance = _mainDoc.Create.NewFamilyInstance(_placmentPt, familySymbol, StructuralType.NonStructural); //do rotation Line axis2 = Line.CreateBound(_placmentPt, _placmentPt+10*XYZ.BasisY); var angle = _refDir.AngleTo(XYZ.BasisY); bool success = (psfInstance.Location as LocationPoint).Rotate(axis2, angle); } else { psfInstance = _mainDoc.Create.NewFamilyInstance(_placmentPt, familySymbol, _refDir, _mepEle.level, StructuralType.NonStructural); // to overcome rotation in xy plane , this is the only overload that has refdir and it works well. the host here is the level containing Family Instance. }

This is what I have done for the rotation, @jeremytammik can you please take a look as the logic and variables are not clear in the link that you posted.

I guess you are right.

but what do you mean by cut and connect?
cut ==> split ?
