Save time and create high quality BIM models

Your team aims to create high quality BIM models without any issues. To do so, the entire project team should have access to the right BIM requirements and to all relevant issues which need solving.

BIMcollab ZOOM is easy to learn and helps to find information flaws, to communicate them in early stages via BIMcollab Cloud and to verify solutions. It's the only free model viewer and BIM validation tool that is fully integrated in issue management workflows.

Detect, share, solve.

Why you need BIMcollab ZOOM

Validate more efficient with smart views

With smart views you can dynamically show and color- code components based on their properties and quickly gain insight in the quality of the information in your BIM model. When the results of a smart view identify a problem, you can immediatly create an issue for others to solve.

Unique and unparalleled is the auto color feature. With this option, you can color-code components automatically based on selected properties, without having to specify them one-by-one. 

You can easily share smart views with team members via drag & drop and define them to be project specific or project independent. It's up to you.

Batch issue generation (Pro)

When dealing with hundreds of clashes, the batch issue generation speeds up the proces of communicating clashes.

Single click annotations

Add texts, arrows, dimensions, revision mark-ups or property-stamps to issue-viewpoints for easy communication.

Check pointclouds against IFC models

Load point clouds and combine them with IFC files to check for deviations between ‘as built’ versus ‘as designed’. You can open point cloud data from common used formats like .e57 and .txt.
