With rapid technical advancement and need to deliver quick turnaround time of construction projects, it has become imperative for contractors, consulting firms, and Architectural Design firms etc. to shift from CAD to BIM Modeling. BIM owing to its parametric modeling properties, ability to provide building data along with 3D geometry has compelled companies to make shift from cad drafting services to virtual construction modeling technology.
Revit Modeling Services
The process during which architects, engineers, and building information modelers create informative 3D parametric models for architecture, structure, and MEP is known as Revit modeling services. Revit allows design and construction professionals to share their work among themselves when 3D modeling is performed in the digital environment. It also allows them to increase the accuracy of 3D design developed in Revit. Revit modeling software develops the high quality architectural design of the building projects.
Over the period of time, Revit Modeling Services has become the most renowned engineering services across the Architecture, Engineering and Construction industry. Revit helps design and construction professionals in the construction of architecture, structure and MEP system of the building by allowing them to generate high-quality design. Revit is considered as the best platform for architects and engineers for design development of building elements. Revit consists of lots of advanced tools that help architects to develop the building architectural design accurately.
Revit allows the users to link the IFC files to the on-going project which helps them to do additional design works effectively. It enhances the collaboration among the project team members. Revit enables all the project team members to share their information with each other without any hassle. Once the architectural model is developed for the project all the professionals can work simultaneously on the same model. Also, they can save their work as files within the central database so that everyone can view the files and access the files easily.
By scanning a 3D Revit model, professionals can detect interferences among various elements of the building system. Once the building architectural design is completely created, professionals can efficiently analyze the design and take effective sustainable design decision regarding the architecture of the proposed building project. Revit modeling services also allow users to modify the entire architectural model. The modified model is automatically updated without any manual effort. This software increases the overall productivity of the project.
Revit modeling software allows the professionals to visualize the architectural design model from all the angles giving a 360-degree view. This view helps to analyze the model efficiently and the required changes can be made in the model if any. Revit modeling services are most significant for architects and engineers for onsite construction as precise design and construction data from the 3D parametric model can be used which are created from 3D modeling services.
The execution of design development process has always been one of the most difficult tasks in the entire construction process. And the matter of fact is that the efficiency of building professionals during actual construction entirely depends on the quality of building design. This clearly means that precise building design is extremely important for building professionals in terms of rapid accomplishment of the project. Considering the importance of building design in construction, a variety of design development software products have been manufactured by software developers.
Some of this software include AutoCAD, Revit – Revit Architecture, Revit Structure, and Revit MEP, Tekla, Navisworks and 3ds Max etc.
Uses of different software products in design development
1. Drawings, which remain one of the most important parts of design development process, are a vital source of design information for architects and engineers
2. And for the accurate development of drawings ( architectural, structural and MEP drawings) building professionals have to utilise advanced software products.
3. One of the most crucial software products, which is mostly used for the development of technical architectural and engineering drawings is AutoCAD.
4. Its tools are so high- tech, that even the most complex drawings can also be generated swiftly by drafters.
5. In addition to that, with its assistance alteration of multidisciplinary drawings have also become quite easy.
6. Apart from developing drawings, the next stage in design process remains the development of 3D models.
7. These days, 3D models are generally developed with Building Information Modeling software such as Revit, Tekla, and Allplan.
8. BIM models include advanced information about construction projects and can be utilised largely for predicting project outcomes. Details regarding design, construction, operations, and schedules etc. are incorporated effectively within Building Information Models.
9. If we talk about Tekla, it deals with everything regarding structural design process. Weather, it is structural detailing, modeling, or structural analysis, Tekla can handle everything effectively.
10. The next crucial software for AEC professionals during design development is Navisworks.
11. It is used for locating and eliminating element collisions.
12. On the other hand, 3ds Max comes into the picture once the technical design of the building is fully completed. It is primarily needed for developing photorealistic images of the building in question.
Family templates are very crucial for developing different types of architectural, structural and MEP components as they contain every bit of imperative information that is required by Revit technicians for starting family creation process. When Revit family creation services are executed by design and construction professionals they fallow a very systematic and organized method during which they first have to effectively plan the family.
Planning is a very important aspect of developing loadable families and in-place families as this leads to sorting out doubts regarding the shape, size and dimensions of going to be developed components.
Family template is chosen after following steps are effectively completed by users
- Revit technicians should find out all the information about the size and dimensions of the family.
- After that they should decide whether the component or the family (architectural, structural MEP component) which they are developing in family editor tool requires any host or not.
- Design and construction professionals should also have all the information about the display of the family in different views, as it largely affects the creation of geometry.
- Once all these things are decided effectively, design and construction professionals can easily select the right family template for developing loadable families and in-place families.
- When it comes to the selection of family templates, host-based family templates are used extensively by Revit users for the development of different kinds of architectural, structural and MEP components.
- Host based family templates are those family templates which provide crucial information to Revit technicians about the components which are hosted by them.
- For example, wall-based family template is a host-based template which provides extensive information about those elements which are hosted in a wall such as doors.
- That means when a door family is developed by Revit technicians, no other family template remains that crucial to them as wall-based family template.
So in this way if the family is effectively planned, Revit users automatically get to know which template should be selected by them.
Earlier when Revit (building design software) was not equipped with the indexing mechanism, then Building Information Modelers had to take the support of additional applications (such as Autodesk ReCap) for changing a raw laser scanned file into a properly indexed point cloud file. It’s true that point cloud modeling services cannot be executed until and unless laser scanned data (which is collected during the survey process, undertaken for the as-built building) is successfully indexed. In other words, the raw scanned data cannot be inserted into Revit.
Method used in Revit for indexing raw point cloud data
- For linking a point cloud file in current Revit project, users are required to index the file before going ahead with the linking option.
- So while selecting the point cloud file for linking in Revit, users are required to click ‘Yes’ for allowing Revit to index the file.
- When ‘Yes’ is clicked by users then Revit creates indexed .rcp and .rcs files from raw scanned data.
- Right after Yes is clicked by Revit users; the Point Cloud File Indexing dialog opens up in front of the screen.
- If in case there are a huge number of files within the list of raw format files then users are required to use the Import Unit Option.
- Under the file location, option Revit users are required to determine the file name and its location.
- Once file location and the file name is specified users are required to click ‘Start Indexing’ option.
- Once the process of indexing raw point cloud files is over, Revit users are needed to click ‘Close.’
- For a single laser scanned file, Revit produces a single .rcp file and a single .rcs file.
This blog is truly imperative for all the Revit users as I am going to provide detailed information about the process of applying a view template to a view in Revit project. A view template which is considered as a set of view properties like discipline, view scale, and visibility settings etc is applied to a view with an intension of implementing standard settings to a view in question.
When it comes to sustaining office standards and maintaining consistency in construction documents it is seriously important for Revit users to implement a view template in view. A view template can be assigned to a single view as well as to multiple views in just one time by users.
Process of assigning view template to a view
- The first step in this process is to select a view or multiple views wherein Revit users want to assign a view template.
- For selecting a single view or multiple views Revit users are required to go to Project Browser. For selecting multiple views from Project Browser Revit users are required to make use of control key.
- Once a view to which Revit users want to assign a view template is selected by users from Project Browser, they are then required to approach Properties Palette.
- Revit users are now required to approach Value Column in the Properties Palette and click the button within it for assigning View Template.
- Revit users should now approach Apply View Template dialog and are required to use View type filter as well as Discipline filter under View Template for the sake of limiting the list of view templates.
- After this Revit users should select a view template that they want to apply to a view from the Names lists.
- Revit users can make use of view properties that belong to another project as a view template for the view or views in question.
- And for doing so they are required to select Show Views and then chose view name from the list.
After this they should click ‘OK’ for applying a view template to a view, which finally completes the process.
Parametric families are very momentous and vital for Revit projects since Revit users can develop them exactly according to clients’ specifications and necessity. One of the most pivotal characteristic of parametric families is that their geometrical composition is governed by Revit users by allotting parameters to them which is often as per clients’ requirements. This clearly indicates that parametric families provide desirable outcomes when it comes to executing Revit modeling services.
Tips for Revit users while creating families in Revit Family Editor
- For developing a family in Revit Family Editor it takes quite a long time for users to accomplish the task. So for saving time and efforts it is always better to nest and share families.
- That means Revit users can easily nest families inside other families for the purpose of creating new families quickly which posses or acquires combined family geometry.
- For example, instead of developing a light fixture family along with a light bulb from the starting point or from scratch, Revit users can develop or generate a combination light family simply by inserting a light bulb in a fixture family.
- When families are shared by Revit users before they are nested it governs or determines the conduct of the nested geometry in those elements that are created with the family.
- In other words if a family is nested by Revit users which is not shared, elements that are developed by the nested family behave as individual or single unit with other elements.
- Revit users do not have the power to edit and schedule these elements individually.
- On the other hand if Revit users nest a family that is shared they can easily edit, select, and plan the components separately.
- Important things that must be known to every Revit user related to nesting restrictions is that no other families except annotation families can be loaded to other annotations.
- No other family can be loaded into details apart from detail families along with generic annotations.
- So it is always a better idea for Revit users to develop a family with nested components.
- So for developing or generating a family with nested components Revit users are required to share the families much before they are inserted or nested in a host family. It is not compulsory that a host family should be shared family.
In this way families can be created quickly in Revit Family Editor.
A floor plan which is also known as ‘Scottish plan’ is a view of a building floor taken by camera from above that completely defines the relationship between rooms and other architectural elements such as doors and stairs etc. of a floor. The foremost and principal motive of developing floor plan is to provide clarity to AEC professionals as well as to clients regarding floor design.
Process of creating basic floor plans in AutoCAD
- For developing floor plans in AutoCAD its users needs to ensure that they have all the architectural drawings at their disposal.
- AutoCAD users should also be equipped with standardized floor plan CAD files.
- Once they have everything in place, they need to open the program or open AutoCAD.
- The next step would be to open architectural construction drawings or CAD files of the floor in the software.
- AutoCAD users will find lots of details in them but what they need to do is to clean up everything that is not required.
- Users are now required to freeze the layers that are unimportant for them. By doing so users can get rid with all the unnecessary elements of the floor plan and this can now be easily transferred. The important layers which are required in the project include doors, stairs, walls, windows, and rooms tag layers.
- AutoCAD users are now required to copy all the crucial components from the architectural drawings so that they can be transferred to existing floor plan file.
- In the next step AutoCAD users should open the standardize floor plan CAD file. This plan will be considered as a template plan later on.
- Users should now past the already copied drawing components or floor plan into this template plan.
- Once the floor plan is pasted into template plan drawing, users should perform ‘save as’ so that the original file is not replaced with it.
- For creating uniformity, users are required to match attributes related to the layers of template plan and newly created plan.
- Delete all the unnecessary lines, headers, and column etc.
- Use ‘Polyline’ tool to create polygon outlines for every utilizable space in the floor.
- Users should now copy the room tags from template plan and edit them. Things such as room number and squire footage number should be edited.
- Once again delete all the unwanted elements from the drawing such as architectural room tags or arcs etc.
- Finally purge the drawings with the assistance of purge command.
- In the existing title block place the floor plan in the center for doing final adjustments. This end up the creation of floor plans in AutoCAD.
