Greetings. I have some files that contain multiple cards in the model (example in the attached image). It is possible to extract each of these cards with cadlib. Thanks in advance

What are cards? Do you mean layouts? Layouts are in DxfModel.Layouts. - Wout

What I see in the image is that the creator of the drawing put several floors of a building into one layout (most probably the Model layout aka Model Space) beneath each other. So what you basically have to do is to find out the position of the placement of the floors, then select entities by their position, and clone them into new drawings depending on where they are. There is a selector for that in CadLib, but I forgot its name, and I cannot look it up right now, but maybe that is already enough info to help you. - Rammi

Thank you. Fixed. Saving each floor of the building in a layout to be able to process them with DxfModel.Layouts
