The objects in the digital model can potentially contain a lot of data not always available or known by the creator of the object or when creating the object. The object geometry is scalable depending on the status of a project. And an object may only be available in a certain geometry or a certain format. To enable and facilitate the adding of data, geometry, size or document to an existing object, BIM&CO lets you collaborate on an object as a user.
I have downloaded a BIM object and I have improved it. I can upload the improved version to make it available to other users.
Let's remember that a BIM object is a set of data allowing the use of this object as if it was an object from the real world. It therefore requires much information, which is not always supplied by the creator of the object.
For example: You want to download a technical object for which maintenance operations will be required. The downloaded object does not contain any information on the clearance space required around the object for maintenance. (Maintenance, Access Zone).
You can add this information in the geometry and upload your work for the community.
If the object has been uploaded by an official manufacturer, the manufacturer shall be informed and will be able to integrate your proposal to the initial object.
