Attached is an example file created in version-19 Deluxe, showing the method I described in my previous post-- creating 3D Objects to subtract from the "wood pieces", to fillet the edges of those "wood pieces".
One group shows using an Extrusion, copied onto four edges of a 2x4 stud, ready for 3D Subtracting.
The other group shows using a Rail Sweep along all four of the edges on the top side of a 2x4 stud (that's not as would be in real-life). I copied the Rail Sweep to the bottom side. This is now ready for 3D Subtractions.
In the Attributes section (Properties/General window/page) of each of the objects, I put in a little note of what they are and what their purpose is.
Most Deluxe Users-- including you skeeter_ca-- probably already know how to do this; but I was bored. -Alvin
