Unity module for a software of industrial automation

The project is designed for a company (that we call CompanyA) that operates in the industrial automation sector and wants to use the software to sale its machinery. The end user is the customer, an entrepreneur, who wants to build his production or prototyping plant with the CompanyA’s machineries. Need: We need a Unity Module linked to our software, a Web App written in Java. The software is realized by us, we need only Unity module! Step 1 Our software allows the end user to create its 2D plant starting from input data which are the two dimensions of the plant. In the software there is a 'play' button that activates the 3D view of the industrial site with the dimensions indicated by the user. What we need is the development of a Unity module (rendering engine) that from the two -dimensional data (length and width, received from a Json File sent by our software, explode a 3D industrial site standard in It can move in compliance with the laws of physics. You can choose an height of 5 meters, standard illumination and industrial windows. The user would also like to be able to use virtual reality. Step 2 Once the 2D layout is created, the software allows the user to access a 3D catalog from which he can choose the machineries of his industrial plant. The software allows the CompanyA to create the catalog of its machineries by loading .stp files. The end user can therefore choose the machineries he wants to insert in his industrial plant and will have the opportunity to position them in the 2D layout. At the moment he will not have the opportunity to place one machine on another. Also in this case, once the 2D positioning is created, the 'Play' button activates the 3D view of the industrial site with the machinery positioned. The Unity module will take the input datas (X and Y coordinates) and will explode the 3D of the machinery. Also in this case the user can move within the industrial site in compliance with the laws of physics. The user would also like to be able to use virtual reality. In general, each end user who creates his system can save and close the file and open it later, make changes that are saved to be able to work on it as many times as he wants.
