You could use an solid element operation to cut a hole with the subtract function. Or you could use a beam or other object in the shape (complex profile) of the hole you want, to "cut" the column by using a stronger building material and putting it on a hidden layer.&nbsp;</P> Mon, 18 Mar 2024 21:05:13 GMT https://community.graphisoft.com/t5/Modeling/Hole-in-column/m-p/595546#M170987 aarkell 2024-03-18T21:05:13Z
