# Chimney - Collar Beam Replacement

At the top edge of the dialog box there is again the option to save the dialog box settings under any desired name. Under this name the setting can then be selected and used in the chimney input.

**Ident number**: Enter the identification number of the replacement collars here or check the checkbox at the right end of the field. If you enable this checkbox, the field for the identification number is deactivated, because the identification number of the replaced collars is then automatically adopted.

**Width**: Enter the width of the replacement pieces, or check the checkbox here as well so that the width is adopted from the replaced collars.

**Height**: Enter the height of the replacement pieces, or check the checkbox here as well so that the height is adopted from the replaced collars.

**Replacement direction**: For chimneys that are installed at an angle to the rafters, you can determine here whether the collars should nevertheless be generated parallel to the chimney (= angled to the rafters/collars) or whether they should continue to be generated perpendicular to the rafters/collars.

**Connection**: Connection between the replacement pieces and the collars. A selection can be made between the saved settings of different connection treatments.
