건축기획_BIM테크니션 모의테스트4

Summary

This fourth BIM architectural-design session demonstrates how to prepare a Revit 2023 project by setting up grids and levels, then defining reusable types for major building components. The focus is on creating and configuring component types rather than completing the full building model.

1. Set Up the Project and Grids

• Start a new project using Revit’s Architectural Template.
• Arrange the Properties and Project Browser panels for easier access.
• Create the plan grids:
  • Set the main X-direction grid spacing to 7,500 mm.
  • Draw the Y-direction grids and copy them at the intervals shown in the plan, including 3,900 mm, 150 mm, and 650 mm.
  • Rename grid labels as needed, and use the copy command with the direction constrained to duplicate grids accurately.
• Add dimensions with the alignment-dimension tool. Adjust overlapping annotations and grid extents for legibility.
• Use reference planes, rather than grids, for additional detail lines and dimensions shown on the drawing.

2. Create Levels and Views

Work in the south elevation, using the existing levels as a starting point.

• Set the first-floor level to 0 and rename it L1F. Keep the associated view name consistent.
• Copy levels upward at 3,000 mm intervals for the upper floors and roof-related levels.
• Create the basement or pit level below the first floor. The demonstrated levels include a 450 mm offset in addition to a 3,000 mm level interval.
• Rename levels and correct overlapping level annotations using Revit’s level controls.
• Extend the grids so they remain visible across the relevant levels.
• Create floor-plan views through the View tools, then adjust grid visibility where necessary.

3. Load and Define Structural Component Types

• Load the concrete column family from Autodesk’s structural-column library.
• Load the concrete beam family from the structural-frame library.
• Duplicate existing types and edit their dimensions and materials:
  • Concrete column: 600 × 600 mm
  • Concrete beam: 300 × 600 mm
  • Assign concrete as the material.
• Place a column between levels. Beams may not appear in the active plan view if they are below the view plane, so check them in 3D.

4. Define Walls, Foundation, and Floors

Create the following types:

• Exterior wall: 200 mm concrete layer with a structural-core function.
• Interior wall: Duplicate the exterior wall type and set its thickness to 100 mm.
• Foundation slab: Structural type with a thickness of 450 mm.
• Floor: Structural type with a thickness of 200 mm.

When drawing walls, set the appropriate height constraint—for example, from the first floor to the second floor.

5. Define Doors and Stairs

• Create a steel single-door type for stairwell entrances: 900 × 2,100 mm.
• Create a wood single-door type for restrooms: 850 × 2,100 mm.
• Duplicate the relevant existing door types and confirm their dimensions and names.
• Create a concrete monolithic stair type with:
  • Stair width: 1,500 mm
  • Riser height: 180 mm
  • Tread depth: 260 mm
• Draw the stair to connect the required floors. Railings are mentioned as part of the session’s scope, but their setup is not demonstrated in comparable detail.

6. Define a Curtain-Wall Type

• Duplicate the curtain-wall type and configure it to cut an opening automatically in the host wall.
• Set the curtain-wall grid spacing to 2,000 mm in one direction and 2,300 mm in the other.
• Specify rectangular grid-member profiles of 50 × 150 mm and 150 × 50 mm for the two grid directions.
• Place the curtain wall between levels, then inspect it in 3D to confirm that it creates an opening in the wall.

7. Define a Ceiling Type and Save

• Duplicate a standard ceiling type and define a 20 mm gypsum-board ceiling.
• Assign gypsum board as the material.
• Place the ceiling approximately 2,300 mm above the floor level, as demonstrated, and review it in 3D.
• Switch the view style to shading to see materials more clearly.
• Save the project file.

The instructor says elevator and restroom sanitary-fixture modeling will be omitted for this exercise.

Main Lesson

The session’s central workflow is to use Revit’s Duplicate Type and Edit Type tools to create project-specific component types, assign their dimensions and materials, and then place them in the model. Grids and levels are established first so that later structural and architectural components can be modeled consistently.
