A section is a cut through the 3d-model. An elevation is different. It shows the face of something, or perhaps more correct, the projection of an object/s to a plane.
Project Definition: Establishing Scope, Vision and Work Effort. In order to have any realistic shot at a successful project, (delivered on time and on budget) the overall vision and work effort must first be fully defined --- i.e. broken down into small, manageable and actionable parts.
Project Definition Template. Purpose: The project definition template provides a framework to set the tone for the project. The contents of the document will give the information required to make the initial decision to proceed with the project. It will also be the yardstick by which management can assess the progress and continuing viability of the project.
