Hello, I would like to know how to efficient creating geometry with predefined layout. For examples in my case : geometry. Their spaces have plenum and doesn't repeat story layout. Currently, i need to create spaces each story layout then take them on the top - build bottom-to-top. My main problems is how to efficiency assign story and name the spaces. Moreover, i need to check each space for surface matching, etc so that the model becomes right. Please give me some advice for saving time spent for this process. Thanks
