Family Creation In Revit: Creating families in Autodesk Revit can be a powerful tool for adding customized elements to your building design projects. Families are essentially pre-made objects that can be inserted into your Revit model and behave just like any other element, such as walls or doors. The main advantage of using families is that they allow you to quickly add complex or unique objects to your model without having to manually draw them each time. In this blog, we’ll cover the basics of creating families in Revit, including an overview of the different types of families, the steps involved in creating a family, and some tips and best practices to follow. Types of Families in Revit Before diving into the creation process, it’s important to understand the different types of families that are available in Revit. There are three main types of families: System families: These are the basic building blocks of your Revit model, such as walls, floors, roofs, and ceilings. System families are pre-made and cannot be edited or modified. Loadable families: These are pre-made families that can be inserted into your model from the Revit library or from a file on your computer. Loadable families can be modified to some extent, but they cannot be created from scratch. In-place families: These are families that are created directly in your Revit model, rather than being inserted from a library or file. In-place families are completely customizable and can be created to meet your specific needs. Creating a Family in Revit To create a new family in Revit, follow these steps: In the Revit ribbon, go to the “Create” tab and click on the “Family” button. This will open the “New Family” dialog box. In the “New Family” dialog box, choose the type of family you want to create. You can choose between three types: Generic Model, Generic Annotation, or Loadable Annotation. Select the appropriate template for your family. If you’re creating a generic model family, you’ll have the option to choose between several different templates, such as walls, floors, or windows. If you’re creating a generic annotation family, you’ll have the option to choose between text, dimensions, or symbols. Click “OK” to create the new family. This will open the “Family Editor” window, which is where you’ll create and customize your family. In the “Family Editor” window, use the various tools and features to create your family. This may involve drawing lines, arcs, and circles, as well as using various constraints and parameters to define the behaviour of your family. Tips and Best Practices for Creating Families in Revit Here are a few tips and best practices to keep in mind when creating families in Revit: Start simple: It’s often best to start with a simple family and gradually add more complexity as you become more comfortable with the family creation process. This will help you avoid becoming overwhelmed and will make it easier to troubleshoot any issues that arise. Use good modelling practices: When creating your family, be sure to follow good modelling practices, such as using consistent and logical naming conventions, keeping your model organized and easy to understand, and avoiding unnecessary geometry. Test your family: Before you finish your family, be sure to test it in a Revit project to ensure that it behaves as intended. This will help you identify any issues or bugs that need to be addressed. Save and backup your family: As with any important project, be sure to save your family regularly and create backups

Level of Detail/Development in Revit Modelling: The Level of Detail/Development (LOD) describes the overall condition of your information model at a specific stage of the design process. This contains the accompanying data as well as the graphical elements themselves. Your model should go from a very rough concept to the as-builts and record drawings over time. According to the AIA E202 contract agreement, this procedure has been standardized into five separate categories. Model Advancement: The idea of model progression lies at the heart of the five-layer LOD. It is critical to understand that not all elements will advance through the model at the same rate or be present at every level. For instance, while essential structural elements may advance through all 5 levels, fittings on mechanical systems could not exist until level 400. Additionally, different disciplines will move through the procedure at various speeds. Structure steel frequently reaches the 400 level before all mechanical has achieved the 300 level. This must be understood by the entire team, who must then create plans to prevent items from reaching the field if their final design will be impacted by model elements that have not yet been established. For instance, steel cannot be released from the 300 level until mechanical loads have been determined. This is just to ensure that the loads required to calculate the steel are accurate. It does not imply that mechanical must be finished to the same degree. Ownership of graphical objects and the data they are connected with may change as the model develops from conceptual to as-built. The changeover from one data format to another may also be a part of this. It is crucial that during this procedure, data accuracy be upheld. Simplifying LOD: At various stages of a project’s development cycle, it is crucial to have a clear description of what is contained in the information model. One of the most crucial components of a BIM-based project’s success is the understanding of expectations, roles, and duties. In order to help with this, GSA has created a number of resources. Please refer to following list to know about the model’s usable features at each stage of development (e.g., level 400 models may be used for exact pricing) LOD 100 (Conceptual) There may not be many brownfield projects that include LOD 100 because it is the beginning of a project. The conceptual design phase of a typical project is fairly comparable to LOD 100. A model will be at its most basic during this stage. A basic site layout may be present, the building will be located, and some very rudimentary evaluations may be carried out. These assessments could involve preliminary whole-site construction phasing, conceptual cost based on cost per square foot, and whole-building energy analysis. There might not always be any model data available for LOD 100. Only analytical data, 2D CAD data, or even hand drawings could be included. When compared to LOD 200 and beyond, LOD 100 is frequently completed by GSA staff or a separate architect. Any model data should, wherever feasible, be developed with the knowledge that it will eventually need to be transferred to a BIM design tool. For instance, if Revit will be used to finish the future designs (200 and 300), a tool that is compatible with Revit should be taken into account for the 100-level massing, modelling, and analysis. LOD 200 (Approximate Geometry) Schematic design and design development are comparable to LOD 200. The conceptual massing model and related data will be transformed during this phase into a model suited for the preparation of construction documents. Given that it includes both the conventional schematic design and design development activities, this is one of the phases that any model will go through that is the longest. By the end of this 200-level course, a model including the approximate number, size, position, and systematic relationships of the majority of the deployed items will exist. Basic information will be initially put in for all object’s data. Even if precise item information might not yet be accessible, space claims for each object or system should at the very least be taken into consideration. During this phase, preliminary high-level coordination should be taking place. Planning should be the main emphasis of coordination, not violent conflicts (e.g., vertical space allotment for utilities not pipe-on-pipe collisions). According to the project’s BEP, this coordination should be cross-disciplinary and conducted at project coordination meetings. LOD 300 (Precise Geometry) LOD 300, the stage where a design starts to precisely resemble what will be built, is comparable to construction papers. The geometry of specific pieces is verified to be 3D. Dimensions, capabilities, and relationships of the object are specified. Upon completion of level 300, a model with the precise number, size, placement, and logical relationships of every object that will eventually be placed will be available. All necessary fundamental data will be entered into the data about all items. There shouldn’t be any rough forms or space demands for any installed object (space claims to protect space for code compliance or similar will still be present). Throughout this phase, individual object level cooperation should be occurring. Major harsh conflicts should be the focus of coordination (e.g., pipe-on-pipe collisions). In this time, the AE and Constructors ought to be present at the coordination sessions. LOD 400 (Precise Geometry) When manufacturing and assembly can be driven directly from the model, LOD 400 is attained. The level 400 information model is produced exclusively by the trade partners with input from the AE for the majority of item types. The design information model frequently becomes inactive at this stage of development while fabrication models are derived from them on a different CAD platform. For design or as-built models, different tools are needed than for manufacturing level models. Trade scheduling is one of LOD 400’s main differences. At levels 100 through 300, various trades are finishing the stages at various times. For instance, the crafts of architectural components, structural steel and foundations, and
