    Rotating object via Rotation parameter on reference line

    Hello I am having a problem rotating something created in the family editor and then inserted into a project.
    I can try toggling the workplane –based and always vertical options both in the family editor and the project itself. Neither approach has the desired effect.

    So I thought I would go to the original object , insert a reference line ( not plane).
    This could be turned into a rotation parameter which would give me the flexibility I want. Soon found out this is rather a difficult issue.
    First there is the issue of attaching extrusion and sweep to reference line.
    Must object be hosted on the reference line in order to get it to rotate when reference line parameter is altered?
    Researching this issue I found locking reference line to reference planes using align too was advised approach.
    You can tab to find a dot representing the end of the reference line. I tabbed but no such dot appeared.
    So I really not sure how to approach this. Can anyone advise?

    Nest your (child) family into another (parent) family and host it it on a ref line in the parent family. Your family will then rotate as one object.
    When you draw your ref line make sure your first click -beginning of ref line- is at the intersection of 2 ref planes you want to align the end to. Then if desired, same with the second click -end of ref line- if desired (there's infinite ways to create families)
    Then <tab> to get the end point and align to both those ref planes. It can be useful to temporarily hide stuff if it's getting in the way.
    Don't forget to link through any parameters (from child to parent) you may need to access from the project environment.

    I can draw new reference line in parent family.
    Picking an object in parent family and choose command pick new host
    I get following prompt: Pick a floor, surface or level to host component
    Does not give me an option to pick a reference line but I pick it anyway and it seems to work
    When I pick cushion under properties the hosted part of properties is greyed-out
    In original cushion I go to Manage > shared parameters and it is blank.
    So do I go back, delete all type parameters and insert shared parameters
    If rotating reference line is only in parent object how will this help?
    I can post a file here if you are prepared to look at it.
