How to combine membrane and shell or solid elements in model

General Questions
1

I have tried to prepare a model that combines shells and membrane elements but I keep getting the error:
**ERROR reading *MEMBRANE SECTION: MEMBRANE SECTION can

  •    only be used for membrane elements.*

  •    Element          123  is not a membrane element.*

Upon investigating this issue it appears that when the .inp file is saved, even though you define the section as a membrane, the type of element assigned is not that of a membrane but a shell element.
Can anybody describe what steps are necessary to resolve this issue?
Your help will be greatly appreciated as always.

You also have to change the element type by going to a part, right-clicking on it and choosing Edit:

membrane
