BuiltInCategory of Doors and curtain wall doors

[desdinova]

Hi friends,

I want to built a plugin that changes the curtain wall panel types

when I try to select curtain wall door how can I filter only panel doors for curtain wall

Is there any specific value for curtain panel door?

Thanks in advance....

As you show in your screen snapshots, the category os the same for all doors, so that cannot be used to tell them apart.

Another possible criteria could be to query the door for its host using its `Host` property:

Using the host element properties, you ought to be able to differentiate curtain walls from others.

Hi Jeremy,

Thanks for reply

I think Host property returns value when the door is placed on the wall.

When i collect familysymbols in door category is it possible to differentiate doors and curtain panel doors?

Thanks again.

[jeremytammik]

Oh yes, in that case, of course, the Host property will not be set.

I am sure you can tell them apart somehow. I cannot tell you how. You might be able to tell by their geometry, parameters, family definition name, dimensions, or other criteria unknown and inaccessible to me.

It is up to your imagination to research and find out...

Thanks Jeremy,

I think I need to study on parameters or create a parameter for curtain wall doors

thanks again.

Hi,

I would not do that, I would rather use Jeremy's hint : find the host and check if it is a Curtain Wall. The parameter for Curtain Walls is: myWall.CurtainGrid which is not null if your wall is a Curtain Wall.

So it is easy to search for such a door : 

FamilyInstance door = null;
if((door.Host as Wall).CurtainGrid!=null)
             // That's my door

Hi Benoit,

Thanks for reply,

Host property is usable when the door is hosted on wall.

But I need to differentiate doors and curtain wall doors in familysymbol level.

Thanks again.

From the FamilySymbol you can find similar types using FamilySymbol.GetSimilarTypes().

This gives you all curtainwall-panels, that can be placed in a curtain wall. Filter the list for the door-category.

FamilySymbol symbol = inst.Symbol;
            
IEnumerable<FamilySymbol> CW_doors = new FilteredElementCollector(doc, symbol.GetSimilarTypes())
            	.OfCategory(BuiltInCategory.OST_Doors)
            	.Cast<FamilySymbol>();

Hi,

there is a Family.IsCurtainFamily property.

So you could check:

FamilyInstance.Symbol.Family.IsCurtainFamily

Thanks Fair59

It works...

[desdinova]

Hi Revitalizer,

Thanks for reply.

But IsCurtainFamily property always returns false.

How can İ solve

I attach the code and rvt file.

Thanks again..

 FamilyInstance familyInstance = doc.GetElement(uidoc.Selection.PickObject(ObjectType.Element)) as FamilyInstance;

            FamilySymbol symbol = familyInstance.Symbol;

            if(symbol.Family.IsCurtainPanelFamily)
            {
                TaskDialog.Show("Revit", "true");
            }
            else
            {
                TaskDialog.Show("Revit", "false");
            }

Hi,

yes, I can see that in the file.

Sorry for confusion.

This topic, appears at least partly resolved, but I would use the Kind property of the host's WallType. Given a list of all doors in project, I would filter using a lambda expression:

doorList.Where(door=>door.Host != null && door.Host is Wall).Where(door=>(door.Host as Wall).WallType.Kind == WallKind.Curtain).ToList();

Hope this works for you.

By parameter： “FamilyPlacementType”
if (_familySymbol.Family.FamilyPlacementType == FamilyPlacementType.OneLevelBased)//OneLevelBased 幕墙门窗
{

}
else if (_familySymbol.Family.FamilyPlacementType == FamilyPlacementType.OneLevelBasedHosted)//OneLevelBasedHosted 普通门窗
{

}

This is how I usually determine it, but again that is after it is hosted.

[rhanzlick]

Upon reading this again, I think my previous answer did not correctly interpret what the OP was asking. From what I can tell, your best bet will likely be to access the "Host" parameter (BuiltInParameter.FAMILY_HOSTING_BEHAVIOR):

door.Symbol.Family.Parameters("Host").AsValueString()

This string should be empty for door families based on curtain panel template, and will be "Wall" for other standard door types. Have not tested this extensively, but so far it looks like it works well as an a priori filter for any family.

[dbrokaw44TRW]

If you were hell-bent on not using, IsCurtainPanelFamily Property, with parameters, you may be able to determine it with the following:

 Parameter wallClosureParam = door.LookupParameter("Wall Closure");

get_Parameter(BuiltInParameter) ; enum TYPE_WALL_CLOSURE

get_Parameter(BuiltInParameter) ; enum DATUM_PLANE_DEFINES_WALL_CLOSURE

Left is Door, Right is Curtain Door Family template .rtf. 


Maybe....?

Revit lookup is giving the value as false for all curtain panel families. It would have been helpful if the value was assigned to it.
