IFC or industry foundation class is like a frozen copy from your model that other users can view, measure, find the clash between items and estimate the cost of the project, regardless they have installed your software in their computer.
You can use from this feature and convert your model to the IFC and then send it to the other groups.
Imagine you have an architectural model and you want to send your model to the other engineer group in order to complete other phases of your project.
In this regard, if you do not convert your file to IFC they must have similar software and similar setting which you have considered for your model, in their computers to see your model correctly.
But IFC solves this problem and you can convert your file to IFC and then send your file to other groups. when they import your IFC file into their software they can see your model there without any problem.
IFC model gives you this possibility that other people can not change your IFC file in their software and if they need to modify or change one part of your model, like create a hole in the wall they should ask you to change that part in your model and create another IFC file and send new IFC file to them.
It helps you to make sure your model is always up to date.
You can also divide your model into different phases and only send your desired phase for the contractor.
Imagine your project have architectural, civil, mechanical, and electrical phases and you want to send electrical and architectural drawings for the electrical contractor, on the one hand, this feature helps you to filter your model and only send the information which your contractor may need and on the other hand your contractor will receive the data that he needs and he works with your model easier.
