Disadvantages of data organization using layers

Besides the numerous advantages, organizing data using layers also has two disadvantages:

• Layers involve some managing work, at least in the beginning.
• If your entire data organization is based on layers, all the data is in one drawing file (i.e. in one file). This means that only one user at a time can access the data. To facilitate concurrent activity, you have to distribute the data that several users need to access onto different drawing files.
