Serious BIM, for the rest of us... A powerful and visually driven BIM converter, editor and viewer of 3D and CAD models.

** requires a Metal compliant 3D device ** allows you to produce BIM contents a posteriori, keeping your mind away from BIM related issues, all along your processes of design or drawing. takes full advantage of the latest Mac technologies and features, to raise your 3D models to BIM databases. Once your 3D model is imported in, you can extend it with a BIM hierarchy, simply connecting and populating the BIM entities by dragging and dropping your 3D objects and layers. Then, you have complete freedom to enhance such entities with standard quantities and properties (Industry Foundation Class™) or by creating yours.

If you need to export your « BIMified » model in IFC2x3™ format, you can buy our PREMIUM PACK extension inside the software. This extension also offers you a complete set of powerful tools to search in your new BIM database, and allows you to extract specific components to apply a common property, or to massively change some of their attributes, for example. is also a powerful 3D visualization tool. It can dynamically render your model, and take advantage of the Metal API to show explicit details with many kinds of rendering options and tools. You can prepare and store these views to advantageously and dynamically illustrate your thought.

Elegant BIM composition at your fingertips
• User-friendly and modern Mac interface
• You can attach any kind of data to the elements of your 3D model

Robiht ,

App unusable.

Constantly asks for permissions to access various folders when trying to open an FBX file. The "Allow" button is dimmed in all instances, so the app won't open a file. Makes it unusable for opening and viweing FBX files.

Developer Response ,

Hi Robiht,
This is due to sandboxing restrictions... Please, give an authorisation to a upper folder, at the root of your project via this same panel, and you'll don't have to give a permission for every external files.

Asks for permissions it does not need

This app is very suspicious. It demands access to every level of your drive, something that no app should have or need. The developer claims this is due to "sandboxing" restrictions, but this is nonsense. This app should only require access to the folder in which your document resides, not to every level above that.

Apple: please review this behavior!

Developer Response ,

Dear eefcee,

Thank you for your concern about security and your attempt to alert Apple. However, your statements are mainly wrong.

Most of the 3D file formats contain links to other external files (images of texture for example). And sandboxing requires that you give permission to all these files. Some of the 3D scenes contain thousand of external files. Giving a permission to a higher level in the folder hierarchy removes the requirement to allow it for each file manually.

That's (quite) funny because one other user recenltly criticized us for the exact opposite assertion.

I needed a software to open a .stl file. Don’t use it daily, but it opened so smooth! Can rotate 3D, very nice!

Thanks to the developers!
