ARCHICAD 21 – Step Up Your BIM

ARCHICAD 21 – Step Up Your BIM

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.

Stair Tool

Designing stairs is one of the most complex tasks in architecture. ARCHICAD 21’s new Stair Tool offers the most optimal stair designs to choose from in the context of the specific building.

Railing Tool

Complex yet configurable railing systems can be created that are associated with Stairs, Slabs, Walls, Roofs or Meshes.

Stair Tool

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.

Railing Tool

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

An ARCHICAD design model can be described as a central BIM database that stores all project data and makes it accessible to any project stakeholder.

IFC Hotlinks

External IFC model content created by consultants - such as Structural or MEP engineers - can be placed as hotlinks into ARCHICAD 21 design projects as protected reference content.

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.

Collision Detection

With the evolution of BIM as the de facto workflow, architects increasingly receive consultant information in a BIM format.

Collision Detection

To help architects fulfil their role as lead coordinator of the model, Collision Detection allows two groups of elements to be compared through user-defined criteria sets. These criteria sets can include Element Types, Classification values, Property values and Attributes, such as Layer names or Building Materials.

Using ARCHICAD’s Mark-Up palette the detected collisions between various elements can be highlighted, identified and edited as needed.


Touch Bar support for the
Apple MacBook Pro

The Touch Bar is a Multi-Touch enabled strip of glass built into the keyboard for instant access to essential tools, right when you need them. By using the new MacBook Pro Touch Bar, architects can easily access the most relevant ARCHICAD controls and commands with ease.

Magic Wand Enhancements

ARCHICAD’s Magic Wand now provides invaluable graphic user feedback about the exact outcome of the operation.

Distribute and align any elements
along paths

Using the Multiply dialogue architects can now distribute and align any elements along paths.

Dashed line presentation

A new algorithm handles the dashed line presentation of polygonal elements so their representation is more natural and reduces the possibility of missing corners.

Uniform Rich Text Format

Uniform Rich Text Format is introduced in all text-related tools: texts, labels, dimensions, interactive schedules.

Individual Composite Dimensions

Dimensions can be placed on the individual layers of composites, including reference line, core only and all layers mode.

Auto-Text with parameters

Auto-Text can now access element specific parameters and properties and also lets the users to create custom labels.

Selective Parameter Transfer

Selective Parameter Transfer allows parameter transfer to only modify certain element parameters selectively. Selected parameter sets can now be stored and applied through Favorites Parameter Inject functionality.

ARCHICAD 21 – In the Press

New stair design system in ARCHICAD 21 relies on PredictiveDesign technology

by Ralph Grabowski, Graphic Speak

The double-entendre marketing slogan for ARCHICAD 21, “step up your BIM,” refers to the improvements generally; but more so the highlight feature: a new stair design system that relies on PredictiveDesign technology. In short, it turns any shape into a stair, taking into account local standards. At the conference, we saw some spectacular stairs designed with the new tool.

For the past few years, GRAPHISOFT has been hosting an annual invitation-only event that brings together its key clients across the world. Called the Key Client Conference (KCC), the 2017 event was held a couple of weeks ago in Kyoto, Japan, and the opportunity to attend it enabled me to get a much better understanding of the use of GRAPHISOFT's products at a global level rather than primarily in North America where I am based.
