I have prolems in closing a chained wall

[Barry Kelly]

Columns, slabs, walls & beams will all automatically trim each other based on the strengths of the building materials they are made from.

It sounds like what you are doing is correct.

You could try using stronger or weaker building materials to control what cuts what.

Or place the cornice (walls) in a separate layer to the column.
But make sure in the layer settings that each layer has a different intersection priority number.
When the numbers are different, the elements will not trim each other.

Having suffered from similar experiences in the past, I suspect the issue occurs due to the overlapping reference lines I.e. the reference line of the cornice follows the outer edge of the column/wall. It seems especially problematic if the column/wall height extends above & beyond the base height of the profile.

With a complex profile, try setting the outside edge of the cornice profile as the reference instead. You can then draw around the column edge & offset (by the width of the profile) using the offset command.

For a wall, offset the reference line in the settings.
