How to get transform of element if familyInstance is null?

[prasannamurumkar]

Required multiple points in Element for some purpose(To Create  obj file) to get right location.

But some elements has issue due to family instance is null.

FamilyInstance familyInstance = targetElement as FamilyInstance;

if (familyInstance !=null)
{
transform = familyInstance.GetTransform();

}

can we use another element transform in same revit model document or can we get transform in any other way?

Many of the elements that are not family instances are defined in place. For instance, a standard wall is defined by its wall type and its location curve. The location curve is given in the global project coordinate system, so its transform is simply the identity transform.
