Allplan 2018: A Milestone in BIM Efficiency and Collaboration

Allplan 2018 stands as a pivotal release in the evolution of Building Information Modeling (BIM) software, specifically designed to empower architects and engineers with enhanced collaboration tools, advanced 3D modeling, and streamlined workflows. Developed by Allplan GmbH, a member of the Nemetschek Group, this version introduced significant upgrades that set a new benchmark for multidisciplinary coordination in the AEC (Architecture, Engineering, and Construction) industry. 1. Seamless Collaboration with Allplan Share

One of the most transformative features of the 2018 release was Allplan Share. This cloud-based tool, powered by Allplan Bimplus, allowed project teams to collaborate in real-time across different locations.

Direct Access: Users could work on the same project data simultaneously without the need for complex local server setups.

Reduced Latency: By leveraging cloud technology, it minimized the administrative overhead traditionally associated with multi-user environments. 2. The New Actionbar: Efficiency Redefined

The user interface received a major overhaul with the introduction of the Actionbar. This task-oriented ribbon menu significantly reduced the "click-path" for frequent commands. allplan 2018

Context-Sensitive Tools: The menu dynamically changes based on the task—whether you are modeling a floor plan, detailing reinforcement, or generating sections.

Customization: Users could tailor the Actionbar to their specific needs, ensuring that the most relevant tools for architectural design or structural engineering were always within reach. 3. Advanced 3D Modeling and IFC4 Support

Allplan 2018 reinforced its position as a leader in "Open BIM" by being one of the first to provide comprehensive support for the IFC4 export format. This ensured that high-fidelity data could be exchanged with other stakeholders using different software suites.

Parametric Modeling: Improvements to the Parasolid modeling kernel allowed for more complex, free-form geometries with greater precision.

Automated PythonParts: The integration of Python-based parametric objects (PythonParts) enabled users to create complex building components that adapt automatically to changes in the model. 4. Precision Engineering: Reinforcement and Sections Allplan 2018: A Milestone in BIM Efficiency and

For structural engineers, Allplan 2018 offered unprecedented speed in detailing.

Labeling and Detailing: Enhanced automation in reinforcement labeling meant that changes in the 3D model were instantly reflected in 2D schedules and sections.

Section Management: A new way of handling sections and views allowed users to generate and update architectural drawings directly from the 3D model with minimal manual cleanup. 5. Visualization and Rendering

The release integrated the CineRender engine by Maxon, allowing architects to produce high-quality visualizations directly within the software. This bridge between BIM and high-end rendering meant that presentation-quality images could be generated without exporting to external software.

Allplan 2018 wasn't just a simple update; it was a strategic shift toward a more connected, intuitive, and data-rich design environment. By prioritizing the Open BIM philosophy, it ensured that professionals could work more flexibly in an increasingly digital and globalized industry. How to Download the Documentation If you need

Looking Back at Allplan 2018: A Bridge Between Classic CAD and Modern BIM

In the fast-paced world of AEC software, three years can feel like a generation. While we are now several versions ahead of Allplan 2018, it is worth taking a moment to revisit this specific release.

Why? Because Allplan 2018 represented a pivotal moment. It was the version where the lines between "pure drafting" and "Building Information Modeling" finally became indistinguishable for many users.

Here is our retrospective on what made Allplan 2018 a workhorse for engineers and architects.

3. Twin Towers: Parametric Modeling for Highrises

Allplan 2018 included a dedicated toolset for facade modeling and highrise structures. The "Twin Towers" functionality allowed users to create parametric storeys.

  • Users could define one floor, and the software would generate variations of that floor (penthouse setbacks, lower-level retail heights) with min/max constraints. This reduced modeling time for skyscrapers by nearly 60%.

Common issues and solutions

  • Performance slowdown on large models:
    • Use partial model views, hide unnecessary layers, and switch to simplified display modes.
    • Increase system RAM and use a discrete GPU with updated drivers.
  • Import/export mismatches (IFC/DWG):
    • Check unit settings, object classification, and tolerance options.
    • Clean up overlapping geometry or duplicate layers before export.
  • Rebar placement errors:
    • Verify concrete element geometry (thickness, cover) and snap/GRID settings; use grouping for repetitive reinforcement layouts.
  • Printing/plotting inconsistencies:
    • Use standardized templates and preview output at final scale; ensure correct paper-size and printer drivers.
