How can I make a 3D model of a mannequin with any dress, then use it online to let anyone use any photo to project on it.

How do you want to use it online?

SketchUp is a 3D modeller, for creating static 3D geometry (with or without textures).
In order to let users

  • Users could open the model in SketchUp Free (SketchUp’s web app) and edit it as they want and replace materials. But I don’t think that is what you want. So you need your own software solution.
  • You could export the SketchUp model into a format that 3D graphics frameworks (Three.js, BabylonJS) on the web are able to read (SketchUp’s Collada, glTF or some JSON). Then you program your own website with such a framework and a file selector. When a user selects a local image file, you programmatically replace a texture on the model.

Basically, Sketchup is not suitable for what you want.
