Onde posso baixar essa poltrona

Hi Joao, unfortunately this brand does not have any BIM/CAD files for its products, so the only thing you can download is the spec sheet.
If you want to only see products that have the right files, you can do a search and use the 'Formats' filter. Here is a blank search that will show you all products with Revit files: https://www.modlar.com/search/products/format--revit/
