Introduction to 3D modeling lab: Build a very simple "proof-of-concept" 3D building model and 4D animation

The lab builds a product and process model of a simple but illustrative building. It introduces you to object-oriented "parametric" 3D CAD and 4D animation of the building construction process.

Notes:

• All the software you need is on each of the CIFE lab computers
• Please see tips for the techniques you need to manipulate software

Lab instructions:

1. Sketch a very simple building (pencil and paper) based on the design (product forms); list a small number of types of physical elements you want in your BIM, e.g., slab, walls, roof, windows.
2. Build CAD model of your building in Revit:
   • Launch Revit Architecture from your desktop;
   • Create a project;
   • Create (vertical) levels: at least two which you will later place the ground floor and roof, possibly another one for a second floor or a foundation.
   • Design (4) walls of the building;
     • as necessary, Zoom to a region so you can see your work.
   • See your handiwork in 3D: View your design in 3D and Dynamically modify your view by rotating it in 3D
   • Parametrically adjust the building footprint:
     • Select a plan view, e.g., in the Project Browser, select Floor Plans > Level 1
     • Select a perimeter wall: mouse select a wall so that its two wall endpoints display as blue circles
     • With your left mouse button depressed, drag the wall to increase or decrease the enclosed floor area. Note how the connected walls follow the wall you move, a behavior that is parametric design in action.
   • Parametrically adjust the floor height:
     • In the Project Browser, expand Views (all), expand Elevations (Building Elevation), and double-click to select an elevation, e.g., East.
     • Mouse select the level line for the roof; drag it up and down.
     • Notice that walls rise and fall with level height when they have a Base Constraint or Top Constraint whose value is locked to a level.
   • Add a floor, roof and any desired additional objects such as interior walls or windows or doors, which you add in a procedure to similar to adding a window.
   • Select a model object, e.g., a wall or a floor and View its object properties.
     • Change an object type to change its material. For example, change the Type property of a wall from Brick to Masonry
     • Note that Revit is object-oriented in the sense that elements of the building model have an underlying symbolic representation as a computer data structure, or table, which has viewable and adjustable properties, such as geometry, whether or not the element is intended to bear structural loads, and possibly cost. Note that, normally, Revit includes the object material implicitly in the object Type.
3. Create model-based analyses:
   • Create a Quantity Takeoff or Bill of Material (BOM)
   • Create a room schedule that lists the sizes of rentable areas
   • Do an interference check for 3D clashes
4. Save your work:

• File > Save As (please place all your files in your subdirectory)
• Export in a format Navisworks can import
