Innovation has been a key differentiator for ARCHICAD since the beginning. ARCHICAD 21 introduces the highly-anticipated Stair Tool, featuring GRAPHISOFT’s patent-pending Predictive Design™ technology. ARCHICAD 21 delivers a number of other, important functional improvements in the fields of visualization, OPEN BIM, performance and productivity making this version one of the strongest in GRAPHISOFT’s history.


ARCHICAD’s Predictive Design Technology™ offers multiple design solutions on the fly and makes sure that the stair will remain compliant.

Stairs consists of multiple sub-elements such as treads, risers, beams, stringers, monolithic or cantilevered structures. Each of these can be individually designed and configured with parametric capabilities.

Create a unique, design-specific, parametric railing pattern and apply this across various building elements with a single click.

Use the Railing Pattern Editor to customize the patters while ARCHICAD will make sure that all pattern changes will be correctly updated along the entire railing system.


ARCHICAD 21’s integrated CineRender - based on MAXON’s Cinema 4D v18 rendering engine - offers architects high quality, photo-realistic rendering in the BIM context.

CineRender introduces Light Mapping and Secondary GI methods for more realistic, yet fast rendering.

Reflectance channel improvements enables to use unlimited number of layers with new Reflection types. Using uniform Surfaces architects may render their project using a custom, single color.

The new Variation shader can be used to vary surface color and shaders randomly across several elements. The new Parallax shader effect inside Bump channel is like Displacement but requires less render time.

Element Classification

ARCHICAD 21 introduces a flexible way to classify elements and spaces for better support of national or company standards and for unprecedented interoperability between project participants.

Classifications for construction elements or zones can be handled in a centralized way within the scope of the project using the new Classification Manager function.

Element classification can be defined; its related properties can be set and transferred between projects via XML file format.

IFC Hotlinks

IFC hotlinks can be placed into the design as many times as needed. In case of large projects the Model Filter option can be used to narrow the display of the referenced IFC content.

These IFC modules can be easily updated ensuring streamlined roundtrip collaboration with engineers. Collision detection works for hotlinked IFC module elements too.



The GRAPHISOFT BIMx is a professional BIM project viewer featuring BIMx Hyper-model, a unique technology for integrated 2D & 3D building project navigation. BIMx Hyper-models offer extremely smooth handling and outstanding performance even for projects with complex/large 3D building models and excessive 2D documentation.

BIMcloud allows a BIM workflow on any network, hardware or software configuration, connecting teams and projects of any size or setup.

The GRAPHISOFT MEP Modeler™ is an Add-On to ARCHICAD®. Firms using ARCHICAD can use the MEP Modeler to create and edit 3D model-based MEP networks (ductwork, pipework and cabling) and coordinate them within the ARCHICAD Virtual Building. The MEP Modeler uses a familiar interface and tools integrated right in the ARCHICAD environment.

The new, physically correct Artlantis 6 rendering engine, with its legendary simplicity, allows you to create visualizations of an incomparable beauty and quality. 


Physical engine

To create stunning images, Artlantis 6 now includes its own built-in physical engine, emphasizing physical rendering quality, precision, material accuracy, and energy conservation.


White Balance

White Balance allows you to adjust the dominant color of a scene to the ambient lighting. Simply set this new parameter to automatic color mode or select a reference color, which will be recognized as white in the 3D scene.


Ambient occlusion

This new option in Artlantis allows users to display a global ambient occlusion to create virtual shadows in small areas where natural light doesn’t go. It brings more depth and relief to both interior and exterior scenes.



White model

During calculation, white model rendering changes all surfaces to white except for those that are transparent. Lights maintain their color for sophisticated environments.


Laser Projection

With a simple click on the reference plane in the preview window, you set the position and orientation of the projection of the laser. A red line projected 360 in the model allows you to automatically position the objects or textures.
