freeware software certified by buildingSMART international - usBIM.viewer+ - ACCA software

usBIM.viewer+ is the only freeware certified by buildingSMART international that allows you to completely modify the IFC file of a BIM model. With usBIM.viewer+ you can:

create an IFC file from any file format or open an IFC file produced with any BIM Authoring applications for architectural, structural, plant design, etc. (Revit, ArchiCAD, Edificius, Tecla, Vector Works, AllPlan etc.)
view all the IFC objects composing the model and work on each of them adding properties, modifying the geometry or deleting them
insert new objects that can be downloaded from any web catalog and in any format

All changes made to the model are saved in a new model in the IFC format.

usBIM.viewer+ completely changes the potential use of the IFC format of a BIM model. The IFC format becomes, in fact, not only a guarantee of access to data over time, regardless of the software with which the model was produced, but also the format in which to you can freely manage the information during the construction and maintenance phase of the building asset.

usBIM.viewer+ is an ACCA software product, the N°1 expert

The BIM choice for those who want freedom of collaboration and ensured data availability.

Import/export IFC - usBIM.viewer+ - ACCA software

Import and export standard IFC files of Open BIM models produced by any BIM Authoring software or Tool

With usBIM.viewer + you can:

import the IFC file of a BIM model created with any BIM Authoring software or tool (Revit®, Edificius®, ArchiCAD®, EdiLus®, Sketchup®, VectorWorks®, Rhino®, Tekla®, etc.)

export the IFC file together with any changes by sharing it for free in the cloud on the usBIM.platform integrated in the software

Open, view and federate multiple IFC files - usBIM.viewer+ - ACCA software

Open, view and federate multiple IFC files simultaneously

With usBIM.viewer+ you open, view and federate IFC format files of 3D models and objects regarding the various design disciplines - even simultaneously – deriving from the main BIM authoring software such as Edificius®, Revit®, ArchiCAD®, Allplan®, Tekla®, VectorWorks® and many others.

With usBIM.viewer+ you can:

Visually navigate through the 3D virtual model using zoom, orbit and rotate features;
Select entities directly in 3D or in the IFC file’s entity structure;
Easily view parts of the BIM model
Check each BIM element’s properties and a detailed set of information (volumes, areas, surfaces, distances, weights and much more)

Viewing, searching, analyzing objects and data contained in the IFC file is very simple thanks to specific functions that allow you to highlight the entities individually or by categories and work on entire levels of the BIM model.

Freely edit and modify the BIM model

usBIM.viewer+ is also an IFC file editor with advanced functions for creating and modifying the BIM model, a true BIM Authoring solution for your BIM models in the IFC file format.

usBIM.viewer+ allows you to:

add new entities to the model
replace the geometry of an existing object without changing its characteristics
move and/or rotate any new or existing entities
delete entities from the model
modify existing properties and define a custom classification scheme
take measurements directly on 3D models

Convert 3D models to the IFC file format - usBIM.viewer+ - ACCA software

Convert your 3D models to the IFC file format

With usBIM.viewer+ open, convert, integrate and export 3D models and objects to the IFC file format originating from many other formats such as, AutoCAD® (.dwg), SketchUp® (.skp), 3D Studio Max® (.3ds) and many others .. even without having your own BIM software!

Transform your 3D virtual model to the IFC standard format, adding many other types of BIM design discipline data to the graphical representation such as, technical, sales, structural, plant engineering and cost estimating information, etc.

Discover all the features

Easily add IFC properties

With usBIM.viewer + add custom IFC properties to 3D models and objects and integrate the information with further technical, commercial, structural, plant, metric and many other data ... without having to own BIM software!

Easily implement all the specifications necessary to completely define the BIM model.

Use the advanced features of a BIM authoring for free to implement the information contained in the BIM model and make communication during the design, execution and maintenance of the most efficient and reliable work.

Comparison of multiple 3D models

With usBIM.viewer +:

compare multiple 3D models in one view
simultaneously view all design phase aspects (architectural, structural, technical systems, etc.)

Specific functions (Snap, Move, Rotate, Align) allow you to easily overlay and update different BIM models.

Highlight specific BIM Model #TagBIM properties

With usBIM.viewer+, you can easily highlight specific properties of a BIM object using the #TagBIM operator to make important information easily visible in other activities of for creating or updating the BIM model (design, execution or maintenance phases of the asset).

Using #TagBIM also simplifies the way you search for information that was written by other users in the model.

#TagBIM, managed by usBIM.viewer+, are recognizable by any other BIM Authoring or BIM Tool application. A digital recognition facility that allows you to automate the execution of activities or the preparation of project documents (eg: cost estimates, facility management plans, etc.).

Create groups and selection filters

With usBIM.viewer+:

create custom views with Filters and Selection Groups
speed up and simplify the understanding of the BIM model

With selection groups and saving views, quickly analyze the BIM model , single or federated, and eliminate any waste of time due to manual operations.

FAQ (Frequently Asked Questions)

I have received an IFC file and I need to view it to be able to make an offer. Is there a way to open the IFC model?

IFC is an open and non-proprietary file format that allows full interoperability and exchange of data without the risk of introducing errors or loss of information. It is therefore the common language that allows the various professionals and role players of construction process to dialogue with each other.

A fundamental characteristic of the BIM process, in fact, is the collaboration between the various team members involved in the different phases of the structure’s life cycle to insert, extract, update or modify the information present in the model.

With usBIM.viewer+, you can open and view any type of IFC coordiantion view 2X3 files even when produced with different BIM authoring software; furthermore youcan also open other types of 3D models (.skp, .dwg, .dae, etc.) by converting them to the IFC format.

With usBIM.viewer+ can I also edit IFC files?

Yes, usBIM.viewer+ is a true IFC file editor with advanced BIM model creation and editing functions. usBIM.viewer+ also allows you to add properties to IFC files, in order to enrich existing information with additional technical, commercial, structural, plant, cost and many other data types. And all this without having the need for a BIM authoring software.

I have 3D models in the AutoCAD® and SketchUp® format ? Can I convert them to IFC?

In addition to opening and editing of IFC files, usBIM.viewer+ also allows you to open, convert and export files in the IFC2x3 file format and even load other 3D model files exported with AutoCAD (.dwg), SketchUp® (.skp), 3D Studio® (.3ds) and many others too, and without the need of a dedicated BIM software.

With usBIM.viewer + can I collaborate in the BIM process?

Yes of course! With usBIM.viewer+ you can collaborate in the BIM process because:

it’s a software certified by buildingSMART international for IFC import;
it has integration functions with the usBIM.platform cloud collaborative platform.
