Problem How do add custom patterns to the wall?Solution
First, create the pattern as per your requirement using MicroStation or OpenBuildings Designer. Then save that file as the cell (.cel file).
Then place the cell file in the ‘Cell’ folder at the DataSet level as per your choice, (here we have placed it under DataSet_UK) Then open any new file in OpenBuildings Designer and go to Part/Family Editor, From Part/Family editor dialog expand ‘Arcitechural_part.xml’, Then click on ‘A-wall’, From an existing part create a copy of that part from its right-click dropdown menu, And paste it here and change its name, Now from 'Part View' dropdown go to ‘Cut pattern’, After that go to the ‘Pattern Cell’ column which lies on the extreme left. Then for your custom part choose your custom cell from the dropdown, Then click on the loading icon to load the change and close the dialog. Then apply the new part using the ‘Apply Part’ tool in any already placed wall, In the wall’s cut section in (Plan view), you will see the pattern,
