Graphisoft BIMx

Graphisoft BIMx brings project layouts, 3D models, and BIM data together in a .bimx file for architecture and construction work. It serves architects, engineers, construction teams, and clients, with access through web, desktop, and mobile platforms. Users can navigate 3D models and follow hyperlinks from Hyper-models to project documentation. BIMx Issues supports markup on 2D and 3D views, with BCF-compliant issues. Presenter and Gallery support presentations and client exploration, and the Web Viewer can be embedded in a website. Model views can show building-element information such as fire ratings and manufacturer-specific properties. Graphisoft says facility managers and owners can connect Facilities Management databases with a model for maintenance. Model Transfer supports sharing by web link, while private Hyper-model sharing is reserved for Graphisoft Subscribers, SSA, and Forward users. Opening projects in desktop or mobile apps requires a registered Graphisoft ID; without signing in, users can access sample content and one additional custom model. The app and browser viewer are free.

BIMx offers free viewing, navigation, markup, and presentation tools across web, desktop, and mobile. App project access requires a Graphisoft ID, and private Hyper-model sharing has an eligibility limit.

BIMx is for architects, engineers, construction teams, clients, and building owners or facility managers who need to view project models and related information. It can also support presentations and model markup.

Overview

Graphisoft BIMx is a viewer and presentation tool for .bimx files that connect building layouts, 3D models, and BIM data. It is best suited to project teams and clients who need to review a building in context rather than author the model. The free offering is strongest when shared model access and project documentation matter more than private-sharing flexibility.

Key features

Game-like 3D navigation and links from Hyper-models to project documentation let users move between a building view and its related drawings. That makes BIMx useful for reviewing a project with people who need both the spatial picture and the documentation, not just a standalone 3D shape. Element data such as fire ratings and manufacturer-specific properties adds practical context for reviewers.

BIMx Issues supports markup on 2D and 3D views, and its issues are BCF compliant. Measurement tools are also included, giving coordination teams ways to communicate comments and inspect dimensions within the model-viewing workflow. Presenter and Gallery support formal presentations as well as client exploration at their own pace.

The Web Viewer can be embedded in a website, and BIMx Model Transfer can share models through a web link. Private Hyper-model sharing is limited to Graphisoft Subscribers, SSA, and Forward users, so teams without those eligible relationships should not count on private sharing as part of the free experience. Graphisoft also says owners and facility managers can integrate Facilities Management databases with the BIM model for maintenance; that makes BIMx relevant beyond design review where such integrations are part of the workflow.

Pricing

BIMx — free. The plan includes the free app and browser viewer. There is no free trial because the product is free. Browser viewing is the least restrictive way to present a model, while opening projects in the iOS, Android, and desktop apps requires a registered Graphisoft ID. Without signing in, users can access sample content and one additional custom model.

The main trade-off is not a published seat or storage quota, but access and sharing eligibility: private Hyper-model sharing is reserved for Graphisoft Subscribers, SSA, and Forward users. For teams that need private distribution without that status, the free price does not remove the practical constraint.

Platforms

BIMx supports web, Windows, macOS, iOS, and Android, and its supported file format is .bimx. Graphisoft lists Windows 11 and macOS 26 or macOS 10.15 for BIMx Desktop; mobile minimums are iOS 15 and Android 11. After sign-in, the app remains authenticated for up to one year with occasional online access, or for up to seven days while offline. That is useful for field or presentation use with intermittent connectivity, but it is not indefinite offline access.

Who it's for

BIMx fits architects, engineers, construction teams, clients, owners, and facility managers who need to navigate a building model alongside its documentation, discuss issues, or present a project. It is a weaker fit for teams that require private Hyper-model sharing but do not have an eligible Graphisoft subscription or license status.

Pros and cons

• Pros: Combines layouts, 3D models, and BIM data in one .bimx file, so reviewers can relate geometry to project documentation.
• Pros: BCF-compliant markup on 2D and 3D views, measurements, and presentation tools support review and stakeholder communication.
• Pros: Web embedding and link-based Model Transfer provide ways to show models outside the desktop and mobile apps.
• Cons: A Graphisoft ID is required to open projects in the apps, which adds an account step for collaborators.
• Cons: Private Hyper-model sharing requires Graphisoft Subscriber, SSA, or Forward status, limiting controlled sharing for other teams.
• Cons: Offline authentication lasts up to seven days without internet access, so extended disconnected work is not supported on that basis.

Alternatives

For broader 3D viewing choices, compare BIMx with the 3D Model Viewer Software category; for design and building workflows, see Architecture Software.

Nanome is worth considering if its free Starter / Free Web Seat limits—3 workspaces, 1 project, 50 MARA credits, 5 most recent files, and 7 days of chat history—fit your needs. Choose Aspose.3D Viewer for a free viewer across Android, iOS, Linux, macOS, web, and Windows. OmniView 3D offers a free Starter option capped at 3 models and 100 MB storage, with auto-deletion after 3 days and a watermark. p3d.in has a free Basic plan with 100MB and up storage, 100MB model size, 1024px textures, and limited private and unlisted models.

BIMx Web Viewer is a free browser-viewing option, with BIMx Pro features on Model Transfer requiring eligible-company membership and Graphisoft ID sign-in. Choose Dalux if a free punch-list tool with unlimited tasks and up to 3 active projects or buildings better matches the work. F3D is a free, open-source option under the BSD 3-Clause License. Marmoset Viewer is included with Toolbag versions 2.07 and newer.

Verdict

Choose Graphisoft BIMx if your team needs a free way to move between a building model, its documentation, and review or presentation tools. Its standout advantage is that connected project context, supported across web, desktop, and mobile. Look elsewhere if private Hyper-model sharing is essential and your organization does not qualify for Graphisoft’s eligible user groups.
