Thank you so much Eric for the solution. 

Hi All,

I'm brand new to CA so this is certainly a newbie issue: Using CAx12

When I make my entry door and transom window a mulled unit - per the CA tutorial - it is giving me casing on the bottom of my door and also deleting my threshold(sill). I would like to keep the casing on the sides and top. Ideally using a 6/8 door with 10" transom to match my window header height. 

I have provided two photos (each has an elevation and 3D view): One before the mull operation when the door and window are separate entities, then one after the mull operation showing my issue. 

Any help is much appreciated - Thanks!
