In this article we want to provide some tips and tricks to supplement or enhance architectural drawings. Architects need enhanced architectural drawings to be able to represent their design concept efficiently.
Of course, you have to start with a proper model in Archicad.
The next step is to find the best view of the model, which helps you represent every detail you want. Nowadays, axonometry’s role is confined to conceptual drawings. Of course, a perspective view also can be the right choice, here you can read about how to set up a perspective view.
In Archicad we can find the required settings to achieve different axonometries. In the Projection Settings dialog presets are available for the basic types of projections.
View > 3D View Options > 3D Projection Settings > Parallel Projections…
Other useful commands are under View > 3D Navigation Extras
The 3D Document allows you to use either the Floor Plan or the 3D view of the model as the basis for creating a document, to which you can add dimensions, labels and additional 2D drawing elements.
Use Graphic Overrides to apply a predefined appearance (color, fill) to different model elements. First, create Graphic Override Rules. A Rule defines what type of elements (based on specific criteria) should be overridden and how they should look like (3D surface, contour line, fill) as a result of the override.
Why do we use Graphic Override instead of re-coloring the elements in their settings?
Because re-coloring an element is a global setting, in every view, even on the rendering, you would see that specific color. If you use the Graphic Override feature, you can have different colors in every view.
First, set up Graphic Override Rules, then create a Graphic Override Combination and apply the Combination.
Use the Override Style panel to define how to display elements that fit this Rule’s criteria.
Check the boxes of the attributes you want to override. For each of these attributes, define the type (e.g., pen color, line type) as applicable.
Alternatively you can also override the Fill Type and Colors instead of the 3D Surface.
A Graphic Override Combination (a View Setting) is a collection of Graphic Override Rules applied to the elements of the model view in a particular order.
To the 3D Document, you can add dimensions and labels.
To place them, use Archicad’s dimensioning tools, plus certain dimensioning functions that are available only for 3D Documents.
To the 3D Document, you can add any 2D elements, such as fills and lines. In this example, we used two types of Fills on top of each other for the sky.

I like this post. Schematic design is an important phase in the design process, and architects used to work a lot during that phase so as to convince their clients.
However, I am not satisfied yet at 100% with the steps you explain here. It's a little bit time consuming. Sometimes, we don't have enough time to prepare different options to present to clients. Each of the options, according to your presentation, requires a different set up through the Graphic Override Combination. We need time to do that.
I don't know if you have already explored the Massing & Site tool(s) in Revit. This tool helps to create the conceptual drawings during the schematic design phase. When the client approves one of the proposals, we can only add true BIM floors, walls, roofs, and so forth automatically. This workflow process helps save lots of time in Revit. You can take a look at the following. I just play with the tool so as to show you how it works:
In Archicad, for example, Graphisoft can develop the Morph tool this way. The same way we can convert the different construction elements into morph. We also want to be able to convert the different elements of the morph into real building BIM elements. It will help us to sketch using the morph tool during the schematic design phase of the project and then transform each element from the massing, realized with the morph tool, into real building BIM elements. This will make Archicad a BIM software much more suited to the design process that architects have traditionally had to follow.
this massing tool is very nice, but it kinda works better for big buildings with many floors and funky shapes. In other situations its more gimmicky as you still have to adjust a lot.
about the isometrics. Yes, they take time. but MUCH less time than doing them for example in autocad 3d, or worse drawing them in 2d. While there isnt a dedicated exploded view in Archicad like in Revit, with a little good Graphic overrides and some layout work one can get automatic isometrics with a very good control of the output.
hallo Graphisoft, it would be nice to have 2D rendered cutouts such as cars, plants and furniture for 2d presentations such as elevations, section and plans
