BIM for Architecture, Engineering, and Construction Curriculum

Exercise 1.7.1: Assigning Materials to a Component

In this exercise, students will learn how to:

  • Assign materials to model elements by object category.
  • Assign materials by altering an element’s type properties.
  • Assign materials by specifying an element’s instance properties.

  • Create a new floor type using a different material and thickness for the deck at the east side of the residence and studio and the ramp coming from the driveway:
    • Open the Exterior Perspective view and note the appearance of the deck. A cast-in-place concrete material has been assigned to this element, and it is displayed with gray shading and speckled pattern.
    • In a plan view, select the deck and create a new type called Wood Patio, then edit the structure for this new type:
      • Change the thickness of the Structure [1] layer to 4" (0.10 meters).
      • Change the material assigned to this layer to Wood Deck.
    • Also assign this material to the ramp from the deck to the parking area.
  • Next, change the materials assigned to the Console Table in the living room of the residence to match the other furniture in the room:
    • Select the sectional sofa component, and determine the materials assigned to the various parts.
    • Select the console table and assign similar or complementary materials to its parts. The materials for this component are specified as instance properties, so every instance of the console table can have different materials.

Exercise 1.7.2: Creating New Materials

In this exercise, students will learn how to:

  • Create new materials by duplicating existing ones and setting the shading color and surface pattern.
  • Replace the render appearance assigned to materials using options available in the Autodesk library.
  • Adjust settings to fine-tune or alter a material’s render appearance.

  • Create the following new materials to be assigned to the Eames chair in the living room of the residence, and choose an appropriate render appearance for realistic and rendered views:
    • Eames Chair Frame―use Teak from the wood library and change the surface pattern to Wood 3.
    • Eames Chair Leather―use Creased Black from the leather library.
    • Eames Chair Metal―use Chrome Polished from the metal library.
  • Assign these new materials to the Eames Chair component:
    • Seat fabric―use Eames Chair Leather
    • Metal parts―use Eames Chair Metal
    • Wooden shell―use Eames Chair Frame
  • Open the Living Room Interior view and choose the realistic visual style to see the new render appearances applied to the elements.

Exercise 1.7.3: Exterior Renderings

In this exercise, students will learn how to:

  • Choose the rendering quality and set the output resolution.
  • Limit the region rendered.
  • Specify sun settings to set the lighting level and cast accurate shadows.
  • Edit background properties for a view to choose how the sky will be rendered.
  • Fine-tune the exposure settings of a rendered image.

  • Using an exterior perspective view, create an exterior rendering of the residence and studio displaying accurate shadows and using Draft quality to reduce the time required:
    • Choose the Exterior: Sun only lighting scheme for this daytime rendering.
    • Adjust the sun setting options:
      • Choose the Still option for the solar study.
      • Set the location to the city near where you were born.
      • Set the date to your birthday and the time to 10:00 AM.
    • Run the rendering and save the results to the project as Exterior Perspective Draft

  • Create another version of this rendering using Medium quality and keeping the other settings the same:
    • When the rendering is complete, fine-tune the exposure settings by opening the Adjust Exposure dialog box:
      • Raise or lower the Exposure Value slightly to brighten or darken the entire image.
      • Adjust the highlights to darken or brighten the brightest portions of the image.
      • Adjust the shadows to lighten or darken the darkest portions of the image.
      • Experiment with the other settings to explore their effect on the image.
    • Save this rendering to the project and name it Exterior Perspective Medium.

Exercise 1.7.4: Interior Renderings

In this exercise, students will learn how to:

  • Set the lighting scheme to include artificial light sources
  • Turn on light fixtures and adjust the dimming level
  • Create light groups

  • Using the Living Room Interior perspective view, create a draft nighttime interior rendering of the living room area using artificial lighting sources to illuminate the view:
    • Choose the Interior: Artificial only lighting scheme for this nighttime rendering. (The sun settings will be ignored).
    • Click Artificial Lights to open artificial lights settings for this view.
    • Turn on the checkbox next to all of the lighting groups except the Studio Lights. You can also select any individual light, then turn it on or off or set its dimming level.
    • When the rendering is complete, click Adjust Exposure to adjust the exposure settings.
    • Raise or lower the Exposure Value slightly to brighten or darken the entire image.
    • Continue tuning the exposure value to create a good compromise between brightness and overexposure.
    • Save the rendering to the project and name it Living Room Interior Draft.

  • Create another rendered view using the medium quality setting to improve the rendering of the shadows and lighting effects:
    • Adjust the artificial lighting settings to dim some of the lighting fixtures:
      • Set the dimming level for the floor lamps to 0.7 (70%).
      • Set the dimming level for the ceiling lights in the seating area to 0.8 (80%).
    • Fine-tune exposure settings of the completed rendering:
      • Find an exposure value that creates a pleasing overall level of brightness.
      • Adjust the highlights to darken or brighten the brightest portions of the image.
      • Adjust the shadows to lighten or darken the darkest portions of the image.
    • Save this rendering to the project and name it Living Room Interior Medium.
