Is there a way or has anybody tried to make 3D space in openstudio using a .Png image?

The FloorSpaceJS, which is in the geometry tab of the OpenStudio application allows you draw over maps or imported plans images. So you are drawing 2d not 3D, but an extrude it to 3D. You could do something similar in the SketchUp plugin. Your question is pretty short, is this what you had in mind, or. We’re thinking about something else, like a perspective photo png being used to create 3D model? If that is the interest there are many different tools, including SketchUp that can use photogrammetry to create models from one or more images.

No, it's not perspective photo, it's basically an orthographic projection( image of building footprints). I have a data set of building footprints in .png format and now I need to make idfs for all the images and I want to automate this process as the data set is huge, so If you could direct me towards resources from where I can learn to use the functions you mentioned before, would be great help. Thanks in advance.

Here is the online documentation. This is not an automated process, it is meant for modeler to trace the image. https://nrel.github.io/floorspace.js/...

There are tools that try to automatically make vector plans from images for general use for AEC, someone could modify one of those to make extruded zone/space models, but I’m not aware of anything like this.

This may not be what you are talking about exactly, but I thought it was related. NVIDIA has created an artificial intelligence framework to create 3D models from 2D images called DIB-R. I'm wondering if this could be used to create a 3D model of a building if you give it a picture from one of the corners?

@bb_designer I've done some limited exploration into what you are looking for (creating spaces from 2D floorplans) by asking companies that have Automated AI platforms (i.e. you give it data and what you are trying to predict and they handle the rest and give you a trained model) and so far I haven't had any luck finding a solution. It seems like a problem that should be able to be solved, but not sure it has yet.
