Model Entities in CRM

The CRM is a collection of model entities that subdivides the project and can be used to support referencing and thus simplify in a process with high frequency of change and concurrency. These model entities all share some characteristics. They all have a geometry definition, does not contain any functional properties, can be presented graphically and can be referenced by other model entities. These model entities are:

• Surfaces

• Curves

• Points

Furthermore, the grid system is considered to belong to the CRM being one very important entity to use for referencing.

When limiting for example a surface by selecting limiting objects, the canvas can sometimes be cluttered and elements to be selected may be presented behind other elements. The user can in this case turn off the shading (using function Current View in the Settings group in the View tab) while selecting and then turn on shading again when the selection is ready.

Note: Turning shading on or off can also be done using short cut key F11.
