If you own a license of Allplan 2018 Top, do not upgrade until you absolutely need IFC 4.3. If you are learning it for a portfolio, master the Parametric Rebar Array and Freeform Shell workflows —those skills transfer directly to the 2024 version. | Feature | Allplan 2018 Top | Modern

Upgrade if you need interoperability with Archicad 27 or Revit 2024. Stick with 2018 Top if you have a large archive of legacy projects or you dislike cloud subscription models. Part 5: Top 5 Workflows to Master in Allplan 2018 Top If you have access to this software, these five workflows are why the "Top" tier costs a premium. 1. The Shell-to-Mesh Workflow Go to Extrusion > Free Form > Create Mesh from Surface . Use this to convert conceptual Rhino geometry (imported via 3DM) into a structural slab that carries reinforcement properties. 2. Parametric Rebar Arrays Don't place rebar one piece at a time. Use the Array along curve tool under the Reinforcement tab. Define distance, overlaps, and hook angles. This is the number one time-saver in 2018 Top. 3. 2D Derivation from 3D Section Cut a complex section through your freeform model. Allplan 2018 Top is exceptional at generating clean, hatched, dimensioned 2D drawings from a messy 3D section cut. Use the Derive 2D from Section tool to keep the drawing live-linked to the model. 4. The "Top" Quantities Table Navigate to Evaluation > Dynamic Quantities . Unlike static reports, this table updates as you model. Filter by "Top" (to see only high-quality structural elements vs. architectural placeholders). Export directly to GAEB (German standard) for bidding. 5. Visualization in Cineware Because this is the "Top" edition, you have the physical render engine. Hit Render > Photorealistic . Set sunlight to "Physically Accurate (2018 model)." Use the Surface blending mode to show concrete seams realistically. Part 6: Troubleshooting Common "Allplan 2018 Top" Issues Based on forum analysis (PlanData, Bautechnik), these are the top three search queries related to errors: Error 1: "License server timeout" on Top features Fix: The 2018 license manager (CodeMeter) is finicky with modern firewalls. Set a static IP for your license server and disable IPv6 on the network adapter. Error 2: "Top Reinforcement Wizard crashes on Shell" Fix: Your geometry has a zero-thickness edge. Use Mesh Healing under Tools > Repair > Delete Zero-length edges before running the reinforcement wizard. Error 3: Bimplus Sync fails after Windows Update Fix: Allplan 2018 Top uses TLS 1.0 for legacy sync. You must enable TLS 1.0 in Windows Internet Options (Security tab) – though this is a security risk. Better to export as .PLN file manually. Conclusion: Is Allplan 2018 Top Still Relevant Today? The search volume for "Allplan 2018 Top" indicates a very specific user: the veteran civil engineer or architect who values stability over novelty. While you lose modern AI and cloud agility, you gain a perpetual license (no monthly fees), a mature codebase (no unexpected crashes), and hardware flexibility (runs on a $500 used workstation). If you own a license of Allplan 2018

Despite newer versions hitting the market, the search term "Allplan 2018 Top" persists among professionals. Why? Because this specific iteration introduced a suite of high-end (Top) capabilities that fundamentally changed how engineers handle reinforcement, free-form architecture, and interdisciplinary collaboration.

For structural engineering offices that focus on reinforced concrete infrastructure—bridges, tunnels, hydroelectric plants—the 2018 Top edition remains a viable production tool. It handles the "big three" (modeling, reinforcement, drawings) without the distraction of cloud notifications or subscription anxiety.

In the rapid churn of Building Information Modeling (BIM) software, annual releases often blur into a haze of minor patches and cloud integrations. However, every decade produces a "golden build"—a version that strikes a perfect balance between cutting-edge features, hardware optimization, and workflow stability. For users of the Nemetschek ecosystem, Allplan 2018 Top represents that zenith.
