Creating host elements of Revit secondary development (doors and windows, etc.) (issue 14)

All right, all right , Return theme ： Today we'll learn about creating a host element ：

Document.NewFamilyInstance Method (XYZ, FamilySymbol, Element, Level, StructuralType)

What is a host element ？ That's a good question , The so-called bacteria parasitize your large intestine every day , Eating your Xiang with relish every day .

No problem , It's like this .

You're dead , They die , The same can be ： Windows and doors are hosts , And the wall is the matrix on which they live .

Think about it. It tastes , Dinner echoed in my mouth .

It's disgusting , Let's change to the example of cooking ： Every program is a delicacy , Now let's prepare the raw materials for this delicious dish ！

1. XYZ： Where are we going to put it ？ Then put it at the origin ！new XYZ(0, 0, 0)
2. FamilySymbol： The family type we want to create Here we create a door M1221

FilteredElementCollector faaa = new FilteredElementCollector(doc);
            faaa.OfClass(typeof(FamilySymbol));// Get all types 
ElementId id = null;// Record type ID


 foreach (FamilySymbol faa in faaa)// find M1221 This door type 
            {
                if (faa.GetParameters(" Type the name ")[0].AsString().Contains("M1221"))
                {
                    id = faa.Id;// Record the of the door ID
                }


            }
            FamilySymbol fs = doc.GetElement(id) as FamilySymbol;// From him ID To get the door family type 

These are as like as two peas. , The main thing is thinking and understanding API Oh .

Element： Let's create a wall here ：

  XYZ start = new XYZ(-10, 0, 0);// The starting point 
            XYZ end = new XYZ(10, 10, 0);// End 
            Line wallLine = Line.CreateBound(start, end);// Draw a straight line 
 Wall newWall = Wall.Create(doc, wallLine, wid, true);// Draw the wall （wid Is the elevation , Look at number 4 strip ）

Level： This is the most trained , I won't repeat it ！

  foreach (Level ll in fil)// Find elevation 
            {
                if (ll.Name.Contains(" First floor "))// Find the elevation of the first floor 
                {
                    le = ll;// Record the elevation 
                    wid = new ElementId(ll.Id.IntegerValue);// Record the elevation ID


                }
           }

StructuralType： I talked about this last issue , Say it again ！ This is the structure type , Remember to reference the structure type ！using Autodesk.Revit.DB.Structure; Here we choose StructuralType.NonStructural, Because we are not structures .

Be on it , Start cooking ！ Throw them all into the pot in order and stew , After all, Xiaobian is a great cook .

   FilteredElementCollector fil = new FilteredElementCollector(doc);
            fil.OfClass(typeof(Level));// Get elevation 
            FilteredElementCollector faaa = new FilteredElementCollector(doc);
            faaa.OfClass(typeof(FamilySymbol));// Get all types 
            Level le = null;// Record the elevation 
            ElementId id = null;// Record type ID
            ElementId wid = null;// Record the elevation ID
            foreach (FamilySymbol faa in faaa)// find M1221 This door type 
            {
                if (faa.GetParameters(" Type the name ")[0].AsString().Contains("M1221"))
                {
                    id = faa.Id;// Record the of the door ID
                }
            }
            FamilySymbol fs = doc.GetElement(id) as FamilySymbol;// From him ID To get the door family type 
            XYZ start = new XYZ(-10, 0, 0);// The starting point 
            XYZ end = new XYZ(10, 10, 0);// End 
            Line wallLine = Line.CreateBound(start, end);// Draw a straight line 
            foreach (Level ll in fil)// Find elevation 
            {
                if (ll.Name.Contains(" First floor "))// Find the elevation of the first floor 
                {
                    le = ll;// Record the elevation 
                    wid = new ElementId(ll.Id.IntegerValue);// Record the elevation ID
                }
            }
            Wall newWall = Wall.Create(doc, wallLine, wid, true);// Draw the wall 
            FamilyInstance fa = doc.Create.NewFamilyInstance(new XYZ(0, 0, 0), fs, newWall, le, StructuralType.NonStructural);

All right. , Look at the cooked food ！
