Generic model level reference

[nayer.girgis]

Hi,

I am having a problem which I couldn't find a solution for. I have created an addon that creates instances of generic model families by using the familyinstance method:

FamilyInstance instance = CachedDoc.Create.NewFamilyInstance(insertpoint, FamilySymbol, StructuralType.NonStructural);

It works fine and the families are inserted in the exact location. However, when I select the instance, it shows that the host is None and it is not referenced to any floor level. Therefore its offset is always referenced to the project 0 level.

How can I link the family instance to the floor level of the active view?

I would really appreciate any help.

Cheers

Nayer

Dear Nayer,

You have to use a different overload of the NewFamilyInstance method.

The exact one to use depends on your family. It needs to take the level or floor or whatever as an input argument to make it the host.

Dear Jeremy,

I think I have to read more on the other overloads of the Familyinstance method and I will keep you updated. BTW I love your blog, I have learned so much from it.

Dear Nayer,

Thank you for your appreciation. I'm glad to hear that.
