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 AutoCAD 2022- What’s New?

The new version of the AutoCAD 2022 the renowned 2D/3D CAD program is now focusing on collaboration tools and automations.

The core of AutoCAD remains the same but with the AutoCAD 2022 and AutoCAD Lt 2022 the idea is to collaborate workflow and automations.

Push to Autodesk Docs/Drive: With this feature the team can view digital PDFs in the field in case reference is required. Using this you can also connect to files which are stored in Autodesk Docs and Autodesk drive or even other cloud storage such as Google Drive, Microsoft OneDrive and Dropbox. Now uploading drawing templates, plot styles and various other support files or create the DWG files is now possible using the AutoCAD web app.

Drawing review using Trace: For designers drawing reviews are extremely important. With the Autodesk’s trace you and your collaborators can markup the DWG files without having to make changes in the original. When you open the markups, you can find the feedback in context of the original DWG file and make the required changes.

You can now collaborate with Share. The moment in which you share your DWG file you are asked to choose who can view it and decide the level of access you want to give to each user with “view-only” or “edit”. Share links can be generated using AutoCAD and the web app, the links open automatically on the web app.

Important Skills to Possess for Revit Mep Professional

In terms of energy and spatial requirements MEP elements are an integral part of any building project. MEP is involved in every step as the project moves forward. To increase efficiency and to absolutely minimize reworks engineers and contractors constantly strives for organization and a well planned schedule.


With the introduction of BIM, several software are now accepted to be at par with the demand of the market and construction project.

Some of the important features of BIM pertaining to MEP are- better coordination to carry out simultaneous tasks, planning efficient construction schedule and clash detection along with the capacity to resolve them.

To create a streamlined, 3D clash-free MEP layout engineers can use Autodesk’s Revit.


The gap between MEP industry requirements and Revit MEP users can be narrowed down by developing skills which does not just involves using the software but also technical and BIM knowledge all of which is involved in MEP. To use Revit MEP in the best way possible the user needs to be aware of all key user interfaces.

What is Autodesk Revit? And how is it useful?

The Autodesk Revit is designed to work according to the way in which architects and designers think. It is building design software built for Building Information Modeling (BIM).

From capturing and analyzing concepts to maintaining your vision through design, documentation and construction the software is of extreme help from all aspects. The information-rich models help in making a much more informed decision to support sustainable design, construction planning, and fabrication. The availability of automatic updates helps in keeping your design and documentation more coordinated and at the same time the feature is reliable.

The conceptual design tools offered by AutoDesk Revit provides a support for your creative flow, the conceptual design tool is easy to use as well. The software allows you to sketch freely, create free-form models with ease and manipulate forms interactively. Definition of forms and geometry as real building components allow a smoother transition to design development and documentation. While you design, the program Architecture will automatically build parametric framework around the form you made.

This component allows a greater level of control, accuracy and flexibility. It allows you take your design from just a concept model to construction document in one single environment.

To turn conceptual forms into more functional design seamlessly you can use the Building Maker feature. To generate walls, roofs, floors and curtain select the faces. To extract information such as the surface area of your building or volume per floor use tools.

Best 10 BIM Applications 2021

The construction industry is merging with information technology more and more every day, and BIM (Building Information Modeling) is the result and future. If your company wants to embark on the BIM train, you should choose carefully which BIM software to use. So, today we will talk about the best 10 BIM applications of 2021.

1. AutoCAD

Autodesk is a formidable name in the construction industry because of this product. Ancient enough to sprout myths about itself, AutoCAD is the number one 3D modeling and 2D drafting software known to people. It started as a purely drafting application, and then evolved into a Virtual Design and Construction giant.

2. Revit

From Autodesk again, Revit is a pure BIM application that is presently the biggest name in the AEC consortium. It has been with us since the beginning of the century.

Revit is exceptional in architectural planning and documentation due to its ability to hold limitless amounts of details inside the drawings, and its parametric modeling approach.

3. SketchUp

SketchUp has been a dear to anyone who ever tried their hand at 3D modeling. Initially cheap, it still remains the most affordable design and modeling solution. While not really BIM per se, there are plenty of powerful plugins for SketchUp that can turn it into a real BIM application.

A sister application, Trimble Connect, from SketchUp’s owner Trimble, is mostly used for the connectivity requirements of BIM.

Secret Tips And Tricks Of Using Revit

Autodesk Revit is a BIM or building information for the architects, landscape architects, structural engineers, mechanical, electrical, and plumbing engineers, designers. The developer is Autodesk. Revit released on April 5, 2000. The operating system for using Revit is 64-bit windows.

Revit is a software product which helps many professionals to work together. It provides different meaningful ways to create models of real world structures and buildings.

The Offset Parameter

Revit component families had a parameter in them which was known as offset. Users are able to move a family up and down by using this parameter in relation to the Reference Level. Though the offset parameter had a limitation due to some reasons.

The first issue of the offset parameter was that it reported only an offset value but did not mention the level from where the user got the offset. The second issue was that the parameter was hard wired. Users could not report it or tag it. So users had to resort to make a labelled reporting dimension with a shared Parameter.

The Elevation from Level Parameter

The new parameter of Revit 2020 was Elevation from Level. It was added in component families. it will sit alongside the existing Offset Parameter.

Top 10 New Features Of Revit 2020 That You Must Know

Revit has brought out the new Revit 2021, but if you are running on Revit 2020 yet, you should know its salient features. Today we will talk about the best 10 new features of Revit 2020 that you must know. These features were developed in response to increasing demands of users, as well as from insights of the developer team.

Path of Travel

If you are into coding, you surely know how difficult it is to code for a path of travel. Granted, Autodesk has already implemented it in AutoCAD, but Ravit has now jumped onto that bandwagon as well.

The new Path of Travel feature allows you to select a “start point” and an “end point”. Revit will then automatically calculate the shortest path between the two points. That means it will avoid walls and try to find doors.

PDF Import

Yes, you read that right. You can now import PDF files into Revit 2020, wow! The PDF will be imported as a 2D object in the current view only. You have to specify which page you want to import each time you select a PDF file. You can also specify a DPI import value.

You can find the Import PDF tool under the Insert tab in the ribbon. Once the snaps are activated, you can use the “pick walls” tool to use the PDF as a reference to create new walls and other model elements. The PDFs can be managed from the Manage Images menu, too.
