Combine Batzal with "FloorGenerator" for the floor slabs and "RailClone" for the gutters. That trifecta turns Max 2020 into an architectural modeling monster.

Residential arch-viz pros who are locked into 3ds Max 2020 and churn out 3-5 houses per week. If you are tired of manually extruding and slicing roof planes, this $85 tool will pay for itself in two days.

The magic happens when you select a closed spline (your building footprint). You click "Generate," and within three seconds, you have a fully 3D, editable poly roof. The algorithm intelligently calculates valleys, hips, and ridge lines. For a standard 90-degree corner house, it is flawless. The "Auto-Roof" button is satisfying enough to make you want to high-five your monitor.

Batzal Roof Designer for Max 2020 is like that reliable, rusty toolbox in your garage. It isn't pretty, the handle is taped together, and you have to hit it twice to open it. But when you need to frame a 12-unit apartment complex before a Friday deadline, it will save your career. Just save your scene before clicking "Generate." You have been warned.

Students using Max 2024/2025 (it won’t work), animators who need deforming roofs (it’s static), or anyone working on organic, curved, or asymmetrical contemporary architecture (think Zaha Hadid). Also, avoid if you hate typing numeric values.
