ArchiCAD 20 is a professional design software for Building Information Modeling (BIM) developed by GRAPHISOFT. It is specifically built for architects, designers, and planners, and is renowned for its powerful 3D modeling, documentation generation, and collaboration capabilities. This article will use the Mac version (Build 4020) as the basis to provide a detailed introduction to its core interface, complete workflow, and efficient operation tips.

I. Detailed Explanation of the Software’s Core Interface and Workspace

After launching ArchiCAD 20, users are presented with a highly integrated and customizable working environment. The main interface areas are as follows:

  • Navigator Panel (left side): The “control center” of the project. It includes the Project Map (used to switch between different views, layouts, and publishers), View Map (stores and manages all saved views, such as floor plans, elevations, 3D, details, etc.), Layer Combinations, Quick Options, and more.
  • Toolbox Panel (left side, usually below the Navigator): Contains all modeling and drafting tools, such as Wall, Slab, Column, Door, Window, Roof, Mesh, Dimension, 2D drafting tools, etc. Tool icons usually have a small triangle, indicating sub-tools or different geometric methods.
  • Info Box (top, directly below the menu bar): This is one of the most important interaction areas. Its content changes dynamically based on the currently selected tool or object, and is used to set and modify all parameters, such as geometric dimensions, layers, materials, brush sets, object settings, and more.
  • Workspace (central area): The area that displays the currently active window (plan view, section view, 3D window, layout, etc.). Multiple windows can be tiled or stacked.
  • Quick Options Bar (below the Info Box): Provides commonly used quick-setting options for the current tool.
  • Status Bar (bottom): Displays information such as coordinates, zoom ratio, gravity snap status, and the current layer combination.
  • Tracker (floating panel): When executing commands (such as Move or Copy), a tracker pops up, allowing users to enter precise values or choose reference points.
Tip: All palettes can be shown/hidden via the menu bar under “Window” > “Workspace”, and you can customize their position and size by dragging their edges. Beginners are advised to first become familiar with the “Full” workspace layout.

II. Complete Workflow from Creating a Project to Exporting

The following workflow will guide you through the basic process of completing a simple building model from scratch and generating drawings.

Step 1: Create/Open a Project

Method: After launching the software, select “Create New Project” or “Open Existing Project” in the “ArchiCAD Starter.” You can also enter the software and use the menu bar File > New or File > Open to do this.

Key Settings: When creating a new project, a “New Project” dialog box will pop up. Here you need to select:

  • Template: It is highly recommended to use a company or custom template, which presets layers, views, annotation styles, title bars, etc., and can greatly improve efficiency. If none is available, you can choose “Empty Template.”
  • Project Location and Story Settings: Define the number of stories, story height, and elevations here. This is the baseline of the BIM model and must be set accurately.

Shortcuts: Cmd + N (New), Cmd + O (Open).

Step 2: Set Up the Working Environment and Grid

Before starting modeling, perform the basic setup first.

  1. Set Up the Grid and Reference Lines: In the floor plan window, use Design > Grid Elements or the “Grid Tool” in the toolbox to draw the grid system, providing a basis for wall positioning.
  2. Switch Layer Combinations: In the “Layer Combinations” drop-down menu in the Navigator palette or status bar, select a layer combination suitable for modeling (such as “00-Modeling”) to hide unnecessary annotation or furniture layers.

Step 3: Core Modeling (Using Walls, Slabs, Doors and Windows as Examples)

Core Principle: Select a tool in the toolbox -> Set parameters in the info box -> Draw in the workspace.

  1. Drawing Walls:
    • Select the “Wall Tool” in the Toolbox.
    • In the Info Box at the top, set the wall structure (composite or basic), thickness, height, reference line position (left/center/right), material, etc.
    • In the floor plan workspace, click the start point, move the mouse, and click the end point. Press the Tab key to bring up the Tracker to enter precise lengths or angles. Use the Esc key to end the current continuous drawing.
    • Shortcut: W (quickly activates the Wall Tool).
  2. Drawing Slabs:
    • Select the “Slab Tool” in the toolbox.
    • In the Info Box, set the thickness, elevation, structure, etc.
    • In the floor plan, create a closed polygonal slab by clicking multiple points (or use the Magic Wand tool to click on wall reference lines). Press the Esc key to close and finish.
    • Shortcut: P (quickly activates the Slab Tool).
  3. Inserting Doors and Windows:
    • Select the “Door Tool” or “Window Tool” in the toolbox.
    • In the Info Box, select the specific door/window type, and set the dimensions, elevation, material, etc.
    • Move the cursor onto the target wall, and click to place it when the preview appears. After placement, you can click to select the door/window and adjust its position and parameters by dragging its handles or modifying the Info Box settings.
    • Tip: Double-click a placed door/window to open its settings dialog for detailed editing.

Step 4: Create Sections, Elevations, and 3D Views

  1. Create Sections/Elevations:
    • Select the “Section Tool” or “Elevation Tool” from the Toolbox.
    • In the floor plan, draw a line segment through the model where you need to generate the section/elevation.
    • Once completed, the corresponding view will be generated under the Navigator > Project Map > Section Drawings (or Elevation Drawings) folder. Double-click to open the section/elevation drawing; the software has automatically completed the cut and projection.
  2. View and Adjust the 3D Model:
    • Open the 3D window via the menu bar Window > 3D View > 3D View, or click the 3D button on the toolbar.
    • In the 3D window, you can use the middle mouse button to rotate the view, Shift+middle mouse button to pan, and the scroll wheel to zoom. You can also use the “Orbit” or “Fly” tools for dynamic navigation.
  • Shortcuts: F3 (switch to the last used 3D window), Cmd + middle mouse button drag (quickly rotate the 3D view).

    • Step 5: Dimensions and Annotations

    Add dimensions and text notes in views such as plan, elevation, and section.

    1. Dimension annotations:
      • Select the “Dimension tool” from the toolbox.
      • In the Info box, choose the dimension type (aligned, linear, angular, etc.) and dimension style.
      • Click the geometric points to dimension one by one (e.g., wall endpoints), then click in an empty area to place the dimension line.
    2. Text annotations: Use the “Text tool” to add notes. In the Info box, you can set the font, size, leader line, etc.
    3. Automatic dimensioning: Use the “Automatic dimensioning” feature (Document > Annotations > Automatic Dimensioning) to quickly dimension an entire wall or area.

    Step 6: Create Layouts and Publish Drawings

    Arrange the various views you have drawn (plan, elevation, section, detail) onto layouts, ready for printing or export.

    1. Open the Layout Book: In Navigator > Project Map > Layouts, you can see the preset layout sheets. Double-click a layout (e.g., A1 sheet) to enter the Layout Editor.
    2. Placing Views:
      • From Navigator > View Map, drag previously saved views (such as “First Floor Plan” or “South Elevation”) directly into the drawing frames on the layout.
      • Select the view in the layout to adjust its scale, title, and other properties in the Info Box.
    3. Final Export:
      • From the menu bar, select File > Publish > Publisher.
      • In the Publisher settings, select the layouts or view sets to publish, set the output format (such as PDF, DWG, PNG), folder, and naming rules.
      • Click the “Publish” button to generate the final deliverable files.
      • Shortcut: Cmd + P (quickly opens the Publisher).

    IV. Common Problems & Solutions

    Problem Symptom Possible Cause Solution
    Walls or other elements are invisible in the 3D view 1. The layer the element is on is hidden in the current view’s layer combination.
    2. The element’s model view options (such as “Show in 3D”) are turned off.
    3. The element is outside the active story.    		 1. Check and switch the layer combination.
    2. Select the element and check its display options in the Info Box or Selection Settings.
    3. In the 3D window’s settings, adjust the “Display Options” to include all stories.
    File operations (Save, Save As) are slow or laggy 1. The project file size is too large, containing too much uncleaned fragment data.
    2. The save path has an unstable network connection (such as a network drive).    		 1. Periodically use File > Save As, and check “Compress” and “Remove Unused Project Data” to optimize the file.
    2. Whenever possible, operate on a local hard drive and back up to the network regularly.
    Content is missing after generating a section/elevation 1. The section line position does not pass through the target model.
    2. The layer the target model is on is hidden in the section’s layer combination.
    3. The section’s “Model Display” option is improperly set.    		 1. Adjust the section line position in the plan view.
    2. Check and adjust its associated layer combination in the section window.
    3. Double-click the section marker and check its “Model Display” settings (such as clipping plane range).
    Shortcuts not working 1. The current input focus is not in the workspace (such as inside a dialog box).
    2. Conflict with other software or system shortcuts.
    3. The work environment configuration file is corrupted.    		 1. Click once on the workspace window.
    2. Check the system keyboard shortcut settings.
    3. Try resetting ArchiCAD preferences (hold Ctrl during startup).
    Unable to snap to desired points (such as wall endpoints, midpoints) The snap toggle is not turned on or is set incorrectly. Check the snap icons in the status bar (such as endpoints, midpoints, intersections) and ensure the required snap types are activated (icons highlighted). You can also configure in detail via Options > Work Environment > Mouse Pointer & Snap Settings.
