Detailed Description

The vtStructure class represents any "built structure". These are generally immobile, artificial entities of human-scale and larger, such as buildings and fences.

Structures are implemented as 3 types:

• Buildings (vtBuilding)
• Fences and walls (vtFence)
• Instances (vtStructInstance)

For enclosed and linear structures which can be well-described parametrically, vtBuilding and vtFence provide efficient data representation. For other structures which are not easily reduced to parameters, the Instance type allows you to reference any external model, such as a unique building which has been created in a 3D Modelling Tool.
