Tekla Structures indicates the work area using dashed lines. Since objects outside the work area exist but are not visible the user can set a certain sized work area so that the views of the model are simpler and quickly updated, for example.

related visibility issues in reference models using a base pointpoint in a model that is used to define a starting point in surveying and that is used as an anchor point in coordinate and height transformations

A Tekla Structures project can have several base points but only one of them can be the project base point.

Base points allow the use of another coordinate system needed for interoperability and collaboration. Base points can also be used in drawings, and in reports and templates. Model origin is the default base point in Tekla Structures.

Base points are also called control points.
