A BIM system can be
defined as a collection of BIM elements creating a group with some common functionality
characteristics. With this definition, to create a system is needed to have or to
create the corresponding BIM elements.
For example,
working on Autocad we are fortunate that many of the elements we need are
already created by the program itself, but other more specific must be created
from scratch.
To create that BIM element
we need the characteristics typical of the element we want to create. They can
be defined in the project, using the property sheets from the manufacturer or
defined by the designer to choose among others with similar features.
After defining the
element we need to create, and according to the property sheets from the
manufacturer, we create the 3D model and add the definition and specific
properties that makes up this element.
In the video here
shown, are taught how to create a MVPart (the basis for creating a BIM element)
starting from a 3D Solid (also created in Autocad) and how to add different
connection points to connect the element
with the other elements that make a System.
