BIM - Introduction + Parametric Modelling Flashcards
What is Building Information Modelling the process of?
Designing, constructing or operating a building or infrastructure asset using electronic object-oriented information.
Building Information Modelling is the use of a shared…..?
Digital representation of a built asset to facilitate design, construction and operation processes to form a reliable basis for decisions.
In a traditional workflow, what happens to the ability to impact cost and performance as you advance through a project?
Decreases
In a traditional workflow, what happens to the cost of changes as you advance through a project?
They increase
What does BIM integration do to a workflow?
Earlier project integration and development, minimising the cost of changes, helping keeping the project on schedule and budget.
What is the graphical data that makes up an information model?
-What shape does a building compenent have?
-What volume, surface area is associated with it?
-Does it collide with any other components?
What is the non-graphical data that makes up an information model?
-What is the type of the component?
-What are its properties, such as material?
What does visualisation data give?
The object a recognisable appearance
What does functional data represent?
Detection zones, enabling the object to be positioned.
What is not a BIM platform?
Models that contain 3D data only and no object attributes.
Models that cannot adjust when changes are added.
Models that are composed of multiple 2D CAD reference files.
What are the benefits of BIM to the owner?
-Concept, feasibility, and design benefits.
-Increased building performance and quality.
-Improved collaboration
What are the benefits of BIM for design?
-Earlier and more accurate visulisations of design
-Corrections arte made
-Generation of accurate and consistent 2D drawings at any stage of design.
-Earlier collaboration of multiple design disciplines
-Extractions of cost estimates
-Improvement of energy efficiency and sustainability.
What are the post construction benefits of BIM?
-Improved commissioning and handover of facility info
-Better management and operation of facilities
In parametric design, the designer defines a model class - what is this described with?
1 - A set of parameters
2 - A set of relations and rules to control the paramters.
What does ‘class’ mean?
A collection of things that exhibit the same characteristics and behaviour.
What do the parameters of a class include?
Distance, angles and rules such as ‘parallel to’
With Autodesk, if you change anything at any time in the project, what does the software do?
Coordinate chnage through the entire project.
What is parametric solid modelling?
The level of definition of complex shapes or assemblies defined by a few parameters.
What is parametric assembly modelling?
An assembly of individual parametric objects by calling in instances of the individual parametric object and specifiying parametric relations between them.
What is topology-based parametric objects or script-based rules?
Embed complex intelligance into a parametric model.
What is parametric modelling?
The creation of a digital model based on a series of pre-programmed rules or algorithms known as ‘parameters’.
What is a parameter?
A variable property based of building components.
If a parameter changes, what happens to the dependant parameters?
Automatic update.h
What is a category?
A group of elements that you use to model or document a building desing.
