Fireplace with Tapered Sides & Front.

[BWoods]

I'm using Chief Architect Premier X11. 

Pardon my bad sketch. I'm looking to make a fireplace similar to the one I've drawn flat against a wall with the upper half tapered on the front and both sides. There is to be a flat recess within the front taper for a tv mount. I drew a polyline in elevation to get the two sides tapered and converted to a polyline solid, but can't figure out how to taper it from the front at this point. 

Also, there is to be a sort of crown molding mantle separating the upper and lower halves. Is this as simple as using the crown molding tool in the library browser and raising it to the height I need?

Thanks. I'll look into it.

Here’s a video I made a while back that goes over some of

the basic ideas you’ll need to know.  The fireplace is a little different but hopefully you’ll get the idea...

Read up on Molding Polylines.

Took a little bit of playing around but this got me exactly what I needed, thanks a ton. Picture is attached for anyone who may be looking for something similar in the future and stumbles upon this thread.
