Understand Sub-Projects
Each Tilos project file contains at least one subproject. A sub-project is required in order to create activities. To clearly display and manage complex construction projects, you can create as many subprojects as you like. Consider a project a container for sub-projects and sub-projects as containers for related activities. Every section of a construction project can be defined as a sub-project and can be displayed in the cell of a view in a plan.
