Constructing a Part in a Part Studio using DXFs

Hello All,

I am trying to build a configurator inside featurescript that will build an aluminium door (from our product line).
Some parts, such as the top bars and skins of the door can be created from standard geometry such as the cuboid command, and a host of other commands such as extrude etc.
However, other parts are made from aluminium extrusions, for which the sketch geometry is too complicated to draw within the featurescript, and the best way is to bring in a DXF file, which we have already sitting in OnShape. 
Assuming inputs are door height, width, clearance, and a whole range of relevant variables, is it possible to import a DXF from an enum - i.e. have an 'if' statement or array so that if a certain model of door is selected the DXF is assigned to a sketch. For example, when a residential flush door will have different profiles to a commercial, the relevant profiles is imported and extruded once the option has been selected. 

For example, a statement such as:

export enum DoorType
    {
        Residential,
        Commerical
    }

if (DoorType == Residential)
    {
        var LockStile = Profile_123,
        var HingeStile = Profile_345
    }

then obviously Profile_123 needs to be assigned and drawn within sketch "LockStile", and then extruded to "DoorHeight - DoorClearance"

Unfortunately I cannot share any documents or screenshots as the nature of the profiles and construction is very sensitive. I could share the raw code, but this will not be very useful without the profiles. 

I have searched around content for the past two days, and cannot really find anything useful on the forums. 

Thanks for your time.
