The Integration of Building Information Modeling data & City Models using Geo-BIM

Building Information Modeling data integrates into 3D city models using commercial and open-source tools. Integration between Industry Foundation Classes (IFC) and City-GML requires converting information between different models. It is also challenging to transform geometries from solid models. BIMs use for solid representations, while city models use for boundary representations.

Increasing numbers of cities use 3D city models for urban planning visualization and simulation. Often, the models include planned buildings as well. The 3D city model of the city can populate with BIM models of planned buildings.

What is Geo-BIM?

In 2019, a Geo-BIM benchmark examined interoperability in the Geo-BIM domain, which allowed Building Information Modeling to integrate with city models. City-GML and IFC tools evaluate tools for converting data. Four datasets evaluated ETL scripts and several software tools. IFC files are modeled differently, inconsistently, as can be seen by the elements. It may be challenging to develop generic programs that can convert IFC data into City-GML models because of this. As a result, IFC elements of the benchmark were translated into generic City-GML objects, inspected, and modified in practice.

The architecture, engineering, and construction (AEC) domain must reach a consensus on standards and guidelines concerning how IFC models should be modeled. Several countries have already undertaken such work. Standardization of city models is also necessary. As a concept document, City-GML 3.0 is slated for approval in September 2021. Interoperability with IFC improved through the implementation of some concepts.

Top 8 Best Practices for Creating Revit Families

Creating custom Revit families are one of the most important tasks in a firm that uses Revit extensively. Whether you are in charge of creating them in-house, or whether you are publishing them online changing the Revit landscape ? you will quickly see that there are some tricks to this matter. And for that, today, we will talk about top 8 best practices for creating Revit families.

1. Keep it simple

Staying minimal is the key to your speed of creating Revit families. Whether you want to detail the level for elevations or represent a plan ? this is a very handy way, because in these kinds of matters unnecessary complications can boomerang, impacting your performance in a bad way. Utilizing symbolic lines and masking regions will help keep your map simple and minimal. Combine this with visibility settings to create Revit families that look simple and minimal but are incredibly powerful.

2. Know where to stop

Over-modeling is often what kills a 3D model ? not a healthy practice at all. You can minimize that using limits while creating assemblies and parts. This will help you to avoid overloading the model with all kinds of unnecessary junk. It is key to your best interests that you consider only the assemblies that you need and discard all else. This practice compliments the above “keep it simple” rule beautifully.

The role of BIM Execution Plan (BEP) for MEP firms

With advancement of BIM, the demand for BIM Execution or Implementation Plan is also increased. BEP facilitates every project stakeholder to get updated with the project. Now MEP firms extensively implement BEP for improved BIM Level 2 execution.

BEP becomes part and parcel for construction projects specifically large and complicated projects like BIM. The basic BEP plan is utilized to make sure that all the stakeholders, architectural, structural and MEP professionals remain on the equivalent page and proceed at the same predefined pace retaining the clear view in focus.

So, BEP in its nature signifies consulting insights on how BIM will be enforced across the project for each professional ranging from designer, MEP engineer, MEP consultant, or a MEP contractor as well as inter-disciplinary design teams and engineers.

How does BEP impact MEP firms?

Specifically MEP firms reap the most benefits from BEP on BIM coordination. Any MEP firm that deals with a complicated construction project plays a significant role across phases to remain organized. With a BIM implementation plan or a BIM consulting partner BEP is formulated easily to make sure that each stakeholder recognizes their part and can adopt the activities consequently and make out what should be anticipated from other disciplines.

• BEP Documents: The information provided in BEP documents comprise of a plan for BIM adoption, how the data in BIM files are generated, controlled, documented and distributed across the disciplines. When Mep Firms can access such information sets, their teams will to able to undertake decisions for fabrication, delivery at site and installation.

• Project Guide: Aside, when major deliverables and a guide to project milestones are evidently defined, MEP engineers and teams who participate in the project at later stages with regards to other design engineers, BEP plays a very important role in adopting up to date decisions.

• BEP for construction projects: BEP for the construction projects also comprise of practical working method with the details of filenames, abbreviations and acronyms, annotations, symbols in mark-up drawings (if any) and lots other used in the BIM model. The detailed plans in BEP with a guide simplify the task of MEP teams; particularly in formulating MEP coordination drawings and finalizing MEP layout.

Advantages of BEP to MEP firms: When BEP are designed with complete documents to integrate various teams and collaborate to accomplish the project in a systematic and phased manner. BEP provides benefits to MEP teams in the following ways.

• Superior communication and management
• Improved collaboration as per standards
• Reduce reworks
• Saving of time and costs

How BIM was employed in San Francisco mega project to improve collaboration

A large-scale development project is going to be developed in Transbay area as part of a rezoning plan to support more density in the transport hub.

The project comprises of a 605-foot residential tower and a 910-foot hotel, condo and office tower — designers at London-based architectural firm Foster + Partners have settled to make a transition from 2D, CAD-based software to Autodesk’s 3D BIM Revit software.

It facilitates the architects to coordinate all design decisions which are undertaken through the software interface in a centralized location.

By employing the cloud-based Revit platform, project stakeholders will be able to avail the most updated information about the project and wide-ranging 3D visuals from any remote location, to allow evaluation of quality and make improved design details at the initial stage of the project life cycle.

BIM simplified the process for exchanging real-time feedback during the modeling process in coordinating the typical and complex “diagrid” cladding on the taller of the two towers.

3D modeling software is very helpful to make proper examinations concerning the design, the massing and the 3D articulation of the project.

The Architects, engineers and contractors utilize Revit to explore through various scenarios, make necessary modifications to any aspect of a building and make arrangement to reflect that change across the model in real time.

The modelling software allows the AEC communities to get access to entire project context and the most updated plans at any specified time and causes earlier decision-making and real-time collaboration to complete the project on schedule and sometimes earlier than schedule.

To reduce risk of structural or spatial conflicts with encompassing structures throughout construction, the designers modeled buildings on the perimeter apart from high-rise models, before breaking ground on the project.

In the same way, a clash detection feature in Autodesk’s Navisworks software facilitates the users to identify and rectify overlapping elements, interferences among moving objects and other design errors in a BIM model before construction. It significantly helps to reduce the constructability risk and the scope of costly rework later in the project timeline.

3D BIM models are “absolutely vital to contractors as they don’t have to get somebody searching for a set of 2D plans and trying to imagine situations and detect [issues].

There were 35 architects to be associated with the Ocean wide Center project, working to coordinate complicated structural components and fulfil design goals, client objectives and seismic requirements.

Autodesk is very popular and best known for AutoCAD but it also developing big range o software for every creative field as well as a line of software for consumers such as Sketchbook, Homestyler and Pixlr. They are also creating some educational version of its software with no cost for qualified students and staff through Autodesk Education Community. They also have some digital prototyping software such as Autodesk Inventor, Fusion 360 and the Autodesk Product Design Suite which are used in the manufacturing industry for visualizing, simulating and analyzing real-world showing a digital model in the design process. Autodesk apps can be used in the iPhone, iPad, iPod and Android and the company continuously more accessible design technology for both professional and new designers, homeowners, students and casual creators whoever wants to make and share their ideas with the outer world.

BIM 360: BIM 360 enhances construction project delivery by supporting informed decision-making throughout the project lifecycle; it also connects the people, data and workflows on every project by doing design collaboration, documentation and reviews etc.

Here are the newest features that can be used by users of BIM 360 and InfraWorks:

Shared Views: These are a quick and simple way for sharing InfraWorks models online without investing in an enterprise-level solution such as BIM 360.

Terrain Contours: These displays has been upgraded with view-based settings to navigate the presentation and visibility of contour lines and elevation text labels or specific major and minor contour intervals can be set to show wile zooming in past a certain point.

Parametric tunnels: InfraWorks is now allows parametric tunnel component parts and groups and users can design tunnels in the context of a total infrastructure project and they can be designed in Autodesk® Inventor® for further use and import into InfraWorks.

Detailed bridge design: InfraWorks road alliance and span end lines can be sent to an Autodesk Structural Bridge Design model to allow a bridge designer or engineer to make a more detailed model and execute refined analysis.

Consolidated road modeling: InfraWorks can consolidate modeling tools; planning roads are for visualization of large networks and component roads are for introductory engineering; in this new release all previous design roads will be automatically transformed to component roads.

Interoperability-

Dynamic integration with Revit: InfraWorks bridges can be actively updated in Revit whenever users modify a bridge in InfraWorks and they will get an option of matching the InfraWroks bridge which avoids losing all the detailed design work that has been done previously in Revit.

InfraWorks Collaboration Enterprise cloud collaboration with BIM 360

Import InfraWorks roads as Civil 3D corridors: While importing component roads from InfraWroks to Civil 3D they will automatically become corridors with surfaces and subassemblies and give users the improved design capabilities that offer by component roads while supporting more strong interoperability with civil 3D.

Civil 3D 2019 (Design) – Fixed vertical curves with high or low points: Civil 3D users now can specify a new kind of fixed vertical curve in an alignment profile to specify a low or high point enabling them for starting the profile design from a specific point. This feature also helps users for developing the rest of a design from a known point and stick to that design constraint in the entire design process.

Rail cants supported in Subassembly Composer: Rail subassemblies that are created in Subassembly Composer now get that ability to read the cant which has been calculated on the alignment and then those cant values are used to build a corridor that can reflect the calculated cant.

Drawing Production – Batch Saves: Now various drawings and template files can be viewed and saved to the newest versions of Civil 3D using the Autodesk Batch Save Utility; custom scripts can now also add in the batch operation which will save time while shifting a project to a newer version of Civil 3D.

Datakit expands its BIM offer with a Revit format reader

Datakit, a leading company in CAD data exchange, unveil its brand new interface: a library to read Revit files (*.rvt), the native format of the well-known Autodesk’s BIM software.

This new interface expands Datakit’s BIM offering, begun in January 2017 with an IFC reader.

“Following our arrival into the BIM world one year ago, and following the positive feedback from our customers regarding our IFC reader, we have decided to expand our offer in order to also satisfy their native BIM data import needs.”, Explains Olivier Rigollet, CEO of Datakit. « As Revit is the most popular BIM software presently, it was natural to complete our range with this format. After one year of work, we are now able to provide a first version to our customers. »

As the other Datakit’s interfaces, this reader is independent of any external API, so it does not require a Revit license to work.

This new interface has been integrated into CrossManager, the standalone software of Datakit. CrossManager’s users are thus able to convert .rvt files to IGES, STEP, PRC and 3DPDF. New combinations will be available in the future.

Datakit expands its BIM offer with a Revit format reader

A Revit file, converted in 3DPDF with CrossManager. The file can thus be opened in Adobe Acrobat Reader™ to be viewed. The instances list of the original model is accessible.

Software vendors can also take advantage of this new interface in order to provide their users with interoperability with Revit format.

This is possible thanks to CrossCad/Ware: a SDK that can be integrated in a third-party software. By integrating CrossCad/Ware in their own application, software vendors benefit from Datakit’s technology, enabling them to access to Revit format data. They can thus read geometrical data along with colors and instancescontained in Revit 2017.x files. The API integration is easy and is seamless for end users.

Datakit expands its BIM offer with a Revit format reader

CrossCad/Ware enables to support Revit files in your own application.

This tool is ideally suited to BIM software vendors, Indeed, It will enable them to offer their users to work from models initially designed with Revit.

But it is also intended to all other fields’ software vendors who want to offer their users the ability to import Revit data.

Many software vendors already have confidence in the robustness of CrossCad/Ware. Already more than a hundred of software from different fields of activity (CAM, ERP, PLM, visualization, simulation, control, metrology, BIM…) rely on Datakit’s technology to read 3D data.

To try Revit files conversion with CrossManager, or to get more information about the software integration possibilities, you can visit datakit.com or contact Datakit at +33 478 396 369.

You will also be able to meet Datakit team during its visit to BIM WORLD event, in Paris on March 29th, 2018.

BRE is going to launch revolutionary BIM DataBook for global BIM professionals

BRE has introduced a new BIM data product library set to provide a solution to the communication issues which arise while interchanging BIM models.

The new Templater tool will eliminate the mess as well as scarcity of interoperability that may arise while distributing standardised product information from BIM and related technologies. BRE Templater (with code by activeplan) will offer core building element definitions (like doors, windows, plasterboard, roof tiles etc.) and is based on international standards like IFC. DataBook is still in beta testing phase and expected to be launched in early 2018.

DataBook Product Library is totally free to use that facilitates the registered users to connect their BIM objects and relate data to a fixed manufacturers’ data source. DataBook offers plug-in functions for authoring tools with options to connect as well as include data on the basis of project phase and exact project roles. It will eliminate the accountability and risk for designers and constructors from employing editable BIM Library objects and at the same time offering them with the perfect manufacturer data required for giving response to the project requirements throughout the project lifecycle.

DataBook can easily control the information flow throughout the design and build process, devoid of the existing complicated geometry.

It will allow BIM to function for everyone, because presently lots of objects are modified manually when projects are transmitted among manufacturers, architects and contractors. It will save huge time and money.

DataBook records BIM Product Library that will function as an unchanging, state-of-the-art and universal data store for all BIM data.

DataBook is expected to be launched in early 2018.

Shape – A new sketchUp-like .dwg-based conceptual modeling software will be launched soon

Belgian CAD developer Bricsys, is going to launch a new SketchUp-like .dwg-based conceptual modeling software known as “Shape”. Shape even begins with a human figure at the 0,0,0 coordinate point (origin) similar to SketchUp.

Shape is specifically developed to deal with the conceptual modeling phases of the architectural design process.

One can access this software for free early in 2018. Shape is a subset of BricsCAD, that adheres to the AutoCAD user experience intimately.

Shape comes with two unique command entry tools available in BricsCAD. The first is Quad cursor, an information resource that provides commands which fluctuate according to the location of the cursor and the current actions of the user. The second is Manipulator, a substitute cursor that arrives while moving objects, to set angles for easier location.

Shape can be used to quickly produce walls and other standard shapes of architectural conceptual design. There is no need for file conversion to employ Shape models in BricsCAD, AutoCAD or any other software that imports .dwg files.

The structural elements are intelligent, similar to other existing BIM editors. Walls, doors, windows and other structural elements transmit metadata of their definition, materials, etc. If the shape of an object is modified, the metadata and any related constraints are updated.

To gather more information, go through the following link aecmag.com
