how do I pick a family instance of a particular object

normally I can do

pRuntime->SelectAll(MyObjectType);

pRuntime->Select(MyObjectPointer);

to select a particular object assuming that MyObjectPointer points to a specific instance of MyObjType

if I want to select MyObjectPointer as a member of a family of type MyFamilyType

would it be

pRuntime->SelectAll(MyFamilyType);

pRuntime->SelectF(MyObjectPointer,MyFamilyType); ??

also, what would happen if I tried to do:

pRuntime->SelectF(MyObjectPointer,ADifferentFamilyType)

assuming that MyObjectPointer was not a member of ADifferentFamilyType, or that ADifferentFamilyType pointed to a different object type

also, is there a way to add an object to a family via a plugin?

either during runtime or edittime

meaning that I have a pointer MyFamilyType, and MyObjectPointer, which is not a member of that family

and I can add the object to the family without the user doing so manually?

normally I can do

pRuntime->SelectAll(MyObjectType);

pRuntime->Select(MyObjectPointer);

No, you should always use the functions that end in F (eg SelectF) because the other ones are deprecated and do not work properly.

That's right, it works the same as selecting it for an ordinary object type.

[quote:17wwbheq]

pRuntime->SelectF(MyObjectPointer,ADifferentFamilyType)

This is only valid if MyObjectPointer is a member of the family "ADifferentFamilyType", you cannot pick objects in types or families they're not a part of. The consequences of this are undefined.

Sorry, this isn't possible.
