Adding walls to a column in Revit

how would i go about creating a wall to cover the faces of a rectangular structural column. I have found when producing some workflows and using surfaces it has produced two layers of wall. any suggestions would be greatly appreciated.

Hello, could you possibly do this with Wall.ByFace? See here:

Try to filter out the edges you don’t need. Now you’re feeding in Wall.byCurve and Height all the edges of a column. You only need the base 4.

thanks very much very helpful

Hi, I’ve encountered the same problem but can’t work out how to filter the base edges of the column.
Any ideas?
Thank you.
