How to best add cap to stone pony wall

[BigKahuna]

I am using a half wall / pony wall of stone and as usual would like to add a stone cap to it.  While I wish Chief would add a cap dialogue box for this where it would allow you to check  box for cap and allow you to selct a moulding profile I cant see that this is the case.

 

I have had to add it as a 3d polyline or moulding attached to the exterior in past but I havent done it in a while . What are best ways to achieve this ?  I tried adding a molding on the room and offsetting out but that doesn't work. I cant attach a molding on the wall covering using exterior.

 

Once it is achieved is it possible to save that wall type with a cap as new wall type ?

 

Thanks for any help.

Click on exterior room, make room molding polyline, set height, open moulding polyline, set desired molding, uncheck "Extrude Inside Polyline", and then break/modify polyline and suppress moldings as necessary.

Thanks  I finally also found the video again on the room molding polyline. So that worked.
