Federation of models - usBIM.clash - ACCA software

Open, view and integrate different BIM models created by different designers and software

It doesn't matter which design software you or your colleagues use.

With usBIM.clash:

  • open and view BIM models or objects in the IFC standard format and also in many other 3D formats (.SKP, .DWG, .3DS, etc.)
  • perform clash detection tasks on projects created with Edificius®, Revit®, ArchiCAD®, Allplan®, Tekla®, VectorWorks®, AutoCAD®, SketchUp®, 3D Studio Max® and many others.

Thanks to the advanced BIM model federation functions, simply work with a single result that integrates throughout the different design aspects (architectural, structural, MEP or plant engineering, etc.)

Detect interferences automatically - usBIM.clash - ACCA software

Detect interferences automatically

From the federated model, entity conflicts are easily detected, such as:

  • elements of separate models that occupy the same physical space (hard clash), for example a pipe duct that crosses a beam;
  • elements with incompatible parameters (clearance clash), such as two elements that are too close to each other for assembly or maintenance purposes.

Just define simple ruleset parameters (type of comparison, type of collision, tolerance values) to automatically check for interferences based on the required analysis type (hard clash, clearence clash, etc.) and the degree of precision that you want to get.

Interference check process - usBIM.clash - ACCA software

Flexibly customize and control the interference checking process

usBIM.clash allows you to choose BIM models and the elements to be analysed with maximum flexibility.

You can select objects from directly within the 3D model in visual mode or define customized rules and associate clash parameters considered to be most appropriate.

Advanced features such as "Selection Groups" and "Selection Filters" allow you to specify the entities upon which to perform a geometery conflict analysis.

Each criterion, chosen for a given analysis, can be stored for later use and therefore becomes part of an analysis repository that can be repeated every time even on updated versions of your BIM models.

In fact, once the conflict analysis criteria have been set, the clash detection can be repeated automatically as the model undergoes progress and every time its updated.

usBIM.clash automatically detects interferences not only with each update of previously analysed models, but also in the case new entities are added to the BIM models.

You are always free to choose the type of grouping method:

  • process as a priority
  • manage with the right degree of depth

How to use the "Selection groups" and "Selection filter" functions

The "group selection" tool works graphically: simply select the entities of the graphic models on which to start the clash detection session so that the program automatically creates a folder in the inspector with all the entities selected for analysis.

Filters and entities - usBIM.clash - ACCA software

The "filter" tool acts by selecting entities that have characteristics that correspond to those indicated in the selection filter. With this tool, easily specify the files to be subject to a clash detection analysis and filter the entities indicating the properties which, therefore, represent the selection criteria.

The "selection group" allows you to select the entities permanently: they will not change as the model changes, always remaining the same over time.

The "filter" tool allows you to automatically analyse all those entities that correspond to the selection criteria expressed in the filter. The new elements added in the models will be automatically taken into account for the clash detection analysis if they correspond to the properties expressed in the filter.

Clash Detection parameters - usBIM.clash - ACCA software

Once the entities on which to perform the clash detection have been identified, the type of comparison will also be set, specifying whether you want to search for true collisions or also identify minimum distances or tolerances between elements. Collisions can also be searched for within the same IFC model or limited to collisions between separate models.

Life Cycle Management of each collision - usBIM.clash - ACCA software

View conflicts immediately and in an intutively clear manner

usBIM.clash provides an overall and concise picture of the entire set of conflicts, their state together with an overall view of the design evolution.

The detected interferences (Issues) are organized and structured in a grid which provide an immediate and clear view of the analysis results, providing grouping, sorting and filtering functions.

With usBIM.clash, easily identify:

  • items that contain the greatest number of conflicts
  • types of interferences encountered (hard clash, clearance clash, etc.)
  • life cycle of each conflict (date of detection, resolution status, etc.)

Thanks to the dynamic link between Issues and BIM, immediately identify and view interfering objects directly in the model. The display settings (framing, zoom, etc.) are memorized and re-proposed for each subsequent selection.

By clicking on the collision, usBIM.clash automatically brings you back to the IFC model entities involved and highlights the collision points.

With usBIM.clash, completing the information for the individual Issues to accelerate the interference resolution processes is immediate and allows you to add:

  • Notes
  • operating instructions in the "comments" section
  • groupings
  • screenshots of conflicting objects

Tabular results can be exported to PDF,  XML, HTML, CSV ou XLSX file formats

Management of life cycle of each collision - usBIM.clash - ACCA software

Manage conflicts dynamically and collaboratively

With usBIM.clash, conflicts are managed collaboratively between the different designers involved.

You are free to choose the preferred format to use to communicate collision issues:

  • export in buildingSMART’s BCF standard format (BIM Collaboration Format) in full compliance with the IFC-Open BIM philosophy
  • export to many other standard formats, such as: PDF,  XML, HTML, CSV, XLSX.

Using the BCF standard, the individual designer an directly view the each issue, the elements affected by the interferences and any other useful information necessary to solve the problem in their BIM application.

The entire collaboration process can be managed with the BIM collaboration management platform usBIM.platform

Cloud platform - usBIM.clash - ACCA software
