Same boat. I used to use CorelDraw from early 1990s and found it great. Guess I got used to it. Also used IntelliCAD for dxf outputs by CorelDraw. And then HullForm to take the offsets from CD and develop the steel plating for a 22m vessel.CorelDraw was good in that it was very easy to adjust properties of an object. Almost intuitive. Select an object and its properties were simply displayed - dimensions, angles, thicknesses, fills etc. Just drew a box in Sketchup and no obvious object properties to simply adjust length and width??And prefer to download as I am often not connected to the www.
