Even though it is technically possible, Revit is not the most appropriate tool to make curtains and blankets. I suggest you to do the architectural portion in Revit, and export the 3d model to 3D Studio (3d Max), and there, you can include all these elements, which are easy to find in the internet, blocks about all kinds of things, beds, ashtrays, lamps, anything.
Thanks for your response.
But there is no way that we can see the Max files and materials to make them.
Max file format or export the materials that we use in Revit
