Abstract Building information modelling (BIM), a high-tech approach for process transformation, handles project complexity and rapid evolution. A BIM-based project's digital assets alter how supply chain partners cooperate to improve the design and construction processes, enabling early problem identification and removal, producing cost and schedule benefits, and improving facilities management and operations after occupancy.

   1. About BIM

      Developing Information Modelling (BIM) is a model-based intelligent method that offers guidance for managing and developing projects more quickly, more affordably, and with less environmental impact.

      The entire portfolio of design, visualization, simulation, and collaboration tools in the Autodesk BIM software makes use the rich data in the intelligent model to help client make better decisions and remove obstacles to better business.

      Although BIM adoption is rising in rich nations, instances of it being used in developing nations are few and far between. According to research, construction companies face a number of challenges related to the socioeconomic and technological environment present in developing nations.

   2. Why for Architects?

A virtual information model could be passed from the Design Team, which includes architects, surveyors, consulting engineers, and other professionals, to the contractor and subcontractors, and then to the owner. This would enable the addition of discipline-specific knowledge and the tracking of changes to each model. The product helps convey vast information to the owners of complex structures well beyond what are already accustomed to having, considerably reducing the information loss which occurs when a new team assumes ownership of the project. By enabling the use of conflict detection, which warns team members about certain portions of the building, BIM can significantly reduce the errors caused by both the Design Team and the Construction Team (contractors and subcontractors).

1. OBJECTIVE AND SCOPE OF THE WORK

   • Describe Revit's parametric linkages and building information modelling.

   • Learn about parametric objects, families, and the user interface, and begin projects with templates.

   • Revit Is Currently Very Useful Software for The Construction Field, Specifically in The Building Information Modelling Sector.

2. METHODOLOGY MODELLING WALLS

Walls are a fundamental aspect of a building model in Revit, and they are represented by predefined system family types that denote their various functions, compositions, and thicknesses. Users can customize these types by adding or removing layers, dividing them into sections, or modifying their thickness and material using the wall's type properties. To insert walls into the building model, users can simply click on the Wall tool and select the appropriate type before placing it in a 2D or 3D view. Once a wall is added to the drawing, users can also adjust, such as adding sweeps or reveals, editing the wall's profile, or inserting hosted components.

Revit Architecture offers three distinct family types of walls that commonly found in buildings, including doors and windows that are typically integrated into the wall

systems.

1. Basic Wall

2. Stacked Wall

1. MODELLING OF WINDOWS AND DOORS

   • Windows in Revit can be installed in plan, section, elevation, or 3D views, and they can be added to any kind of wall (or, in the case of skylights, to an existing roof).

   • Visit OpenHouse.rvt

   • From the Architecture tab, pick Door tool.

   • To load the door, click Load family.

   • From the library, choose Double Panel-1 in the Us Metric.

   • Add a fresh Door Type.

   • Change the name of the door to "D-1000x2100mm." Change the dimension value in the type properties box.

   • After choosing the door, choose the temporary measurement that appears to secure the door's position to the wall.

   • Click the dimension icon to permanently set the dimension. Lock the dimension as well.

2. MODELLING OF ROOF AND CEILING

   A roof is a protective covering that creates or covers a building's top. Revit Architecture allows for the creation of numerous roof kinds. Extrusions, mass instances, or the building footprint can all be used to create a roof. Windows and doors cannot be broken through by a roof.

   2D closed-loop sketch of the roof perimeter produced when walls are selected or lines are drawn in the open. Height is controlled by the Base Height Offset property; Openings are defined by extra closed loops; Created at the level of the view in which it was sketched

   When you use a slope parameter on a line sketch, slopes are defined.

   Adding a Roof by Extrusion

   • Open-loop sketch of the roof profile is produced while drawing the profile in an elevation view using lines and arcs.

   • The position of the sketch in elevation view determines height.

   • Revit determines depth based on drawing size unless you provide start and finish points.

     Adding Sloped Glazing

   • The extrusion method or the footprint method can be used to make sloped glazing. Sloped glazing can join to curtain walls and common wall types and hasone or more slope-defining lines.

   • Construct a roof using the extrusion or footprint.

3. RENDERING

   You will want to portray your building model with real-world materials, texture, and lighting at various points throughout your projects. You will construct rendering in 3D views in Autodesk Revit Architecture to do this. You can produce realistic renderings from within the programmed since the Revit platform employs the Mental Ray render engine as a renderer.

• Choose Schedule and Quantities » Wall should be chosen under Category, then New Construction should be chosen.

• Create a timetable for the current phase in the same manner. Discover differences

• To plan a wall demolition by yourself

• Make a phase filte r that displays destroyed elements.

• To the present view, apply the phase filter.

• When creating a wall timetable, choose Demolished as the Phase.

  1. WALKTHROUGH

     A walkthrough is a camera that travels along a predetermined path. Frames and critical frames make up the path. A key frame is a frame that can be altered, allowing you to move the camera in any direction. Walkthroughs can also be made as an orthographic 3D view instead of the conventional series of perspective views.

     Creating Walkthrough :

     • Open a view in which to set the walkthrough path. Open the project Home.rvt.

     • Change to the ground floor plan.

     • 4 View tab Create panel Drop down 3D view Choose Walkthrough.

     • To build a tour as an orthographic 3D view, uncheck the Perspective option on the Options Bar as desired. Choose a view scale for the 3D view as well.

     • Hover the mouse over a view, then click to add a key frame.

     • To draw the path, move the pointer in the desired direction.

     • To add an additional key frame, click once more. Key frames can be placed anywhere, but they cannot be changed once the path is created. Once the path is complete, you can edit the key frames.

     • By positioning the camera at an angle relative to a chosen level, you can change its height. Choose a level from the From menu and enter a height in the Offset text.

     • This can make it appear as You can complete the walkthrough path by doing any of the following: Press Esc and then click Finish Walkthrough. though the camera is climbing a set of stairs.

1. SOLAR STUDY

A solar study is darkened, three-dimensional view that shows how the building's shadows will change during a day or several days.

Creating and Setting Up a Solar Study Indicate the Project Location Use the nearest big city's address, the project's street address, or the latitude and longitude to describe its exact position. This project-wide setting helps create site- specific shadows for views that require them, such walkthroughs and solar studies.

All 3D views, with the exception of those that employ the Wireframe or Consistent Colours visual Creating Views for Solar Studies style, can display the sun's path and shadows. The sun path is visible in floor plans, elevations, sections, and reflected ceiling plans in 2D views. Use 3D views of the building model to provide the best possible representation of light and shadow on a project.

When Project North diverges from True North, rotate the view to True North to create solar studies that appropriately depict the sun's location in reference to the project. As an alternative, you can define where the sun is in relation to the view when creating a lighting solar study.
