Archicad Hatch _best_ May 2026

Short Story: The Hatch

Marco had been an architect for twelve years, but ArchiCAD still had a way of surprising him.

On a rainy Tuesday, he opened the office file to finish the lobby plans for the new community center. The client wanted the floors to feel warm but modern — a subtle geometric pattern in the terrazzo, not the busy mottled look they’d used before. Marco scrolled through ArchiCAD’s hatch library and found nothing that matched the mood.

He decided to make one.

He sketched a small triangular motif on paper, imagining how light would bounce across the surface. In ArchiCAD’s hatch editor he recreated the tile: three thin lines meeting at a point, a tiny offset between them to give depth. He set the scale so the pattern would read as texture at normal viewing distance and chose a semi-transparent gray to let the base color of the material show through.

Applying the custom hatch to the floor fill, Marco held his breath and hit Render. The pattern transformed the plan like a memory made visible — clean, human, and distinctly modern. The client loved it: “It feels like sunlight on a sidewalk,” she said. Marco realized the hatch had become more than a drafting detail. It was a voice in the room, whispering what the space should feel like.

Over the next week, he reused the hatch in elevation fills, adjusting rotation to follow the slope of stairs and stretching it slightly for a bold visual rhythm down the corridor. The team noticed how a small, carefully drawn hatch could influence material choices, lighting decisions, even furniture layout.

On the last day before the final presentation, Marco exported a detailed PDF. A junior designer asked, “Can I use that hatch too?” He sent her the .pat file and a short note on scale and transparency. She added it to her favorite fills palette and smiled.

That evening, walking home under a patterned awning that echoed his tiny triangles, Marco thought about how architecture was built on layers — structure, light, program, and yes, hatches. A simple graphic, repeated thoughtfully, could stitch a place together.

When the community center opened months later, people lingered on the terrazzo floor, tracing its pattern with their shoes. Marco watched a group of kids play hopscotch on the very tiles he’d imagined on a rainy morning, and he realized a hatch was never just a technical tool. It was a way to leave a subtle signature in the world — small lines that, multiplied across space, became part of someone’s day.

In Archicad, "hatches" are technically known as Fills. They are essential for detailing, floor plans, and section views. This guide covers how to use and customize them effectively. 1. The Five Main Fill Types

Archicad classifies fills based on how they are constructed and their visual purpose:

Solid Fills: Uniform colors or percentage-based opacities (e.g., 25%, 50%).

Vectorial Fills: Preset line-based hatching patterns (e.g., standard bricks, tiles).

Symbol Fills: Patterns made of repeated 2D elements. You can create custom versions by copying 2D lines and pasting them into the fill settings.

Image Fills: Uses .jpg or .png images to create realistic textures (e.g., grass or wood grain) for elevations or floor plans.

Gradient Fills: Linear or radial transitions between two colors, used primarily for graphic enhancement in drafting. 2. Functional Categories

Fills are categorized by how they interact with 3D elements:

Drafting Fills: Purely 2D fills drawn manually with the Fill Tool. They do not represent a 3D building material.

Cover Fills: Applied to the top surface of elements like Slabs, Roofs, and Meshes in floor plan views.

Cut Fills: Displayed when a 3D element is cut in a Section or Elevation (linked to the element's Building Material). 3. Essential Management & Customization

Access Settings: Navigate to Options > Element Attributes > Fills to create or modify patterns. Use Ctrl + T to open settings for a selected fill on your plan.

Setting Transparency: To make a fill background transparent, set the Background Pen to "0" (indicated by a Ø symbol) in the Info Box or Selection Settings.

Scaling Patterns: If a pattern looks too small or large, adjust the Pattern Unit dimensions in the Fill Types dialog. Changing these will refresh all instances of that fill throughout your project. Creating Custom Symbol Fills:

Draw your desired pattern (e.g., a custom tile) using lines or arcs. Select and copy them (Ctrl + C).

Go to Options > Element Attributes > Fills, click New, and select Symbol Fill. Click Paste in the Edit Symbol Pattern window. 4. Alignment and Orientation If your hatch pattern isn't lining up with your design:

Fill Handles: Select the fill and ensure "Fill Handles" are visible (check Model View Options if missing). You can drag the origin point or rotate the alignment vector manually.

Fit to Skin: For composite walls or slabs (like insulation), set the orientation to Fit to Skin in the Building Materials dialog to ensure the pattern follows the thickness of that specific layer.

Distort with Slope: For roofs, enable Align with Slope and Distort with Slope in the Roof Settings to make cover fills follow the pitch of the roof accurately. Common Shortcuts & Tools Fill Tool Located in the Document tab of the toolbox. Magic Wand

In Archicad, "hatch" patterns are referred to as Fill Types. You can create, manage, and apply these through the Fill Tool to indicate materials, represent surface qualities, or add detail to your documentation. Core Fill Types

Archicad categorises fills into four primary types based on their behavior and source:

Solid Fills: Simple, single-coloured fills where you can adjust the opacity percentage.

Vectorial Fills: Made from preset vector line shapes that maintain clarity when zooming.

Symbol Fills: Custom patterns you create yourself by drawing a pattern "piece" and defining it as a fill.

Image Fills: Uses .jpg or .png image files to create realistic textures. How to Use the Fill Tool

Selection: Select the Fill Tool from the toolbox on the left of your workspace.

Geometry Methods: Choose how to draw the fill boundary in the info box: Polygonal: Click multiple points to define a custom shape. Rectangular: Two clicks define the diagonal corners.

Rotated Rectangular: Three clicks to define the angle and width.

Applying Patterns: Select a placed fill and use the Fill Selection Settings or the Info Box to change the pattern and colours. Customization and Settings

Creating Custom Fills: Go to Options > Element Attributes > Fill Types to create new patterns or edit existing ones.

Scaling: In the Fill Types menu, you can set a hatch to be Scale Independent (stays the same size on screen) or Scale with Plan (changes size based on the drawing scale).

Importing Patterns: While Archicad uses its own format, it can convert AutoCAD hatches into Fill Types when importing .dwg or .dxf files.

Problem 1: "My hatch is solid black / printing too dark."

Cause: You assigned a thick pen weight to the fill lines. Fix: Go to Fill Manager, select the hatch, and change the Pen to a lighter one (e.g., Pen 90 for light gray, Pen 5 for thin dark lines). Never use Pen 1 (black) for dense hatches.

Common Archicad Hatch Problems (And Fixes)

| Problem | Likely cause | Solution | |---------|--------------|----------| | Hatch doesn’t show | Wrong view type or scale | Check “Show hatches” in view settings. Hatches have a visible scale range. | | Hatch looks solid | Scale too large or small | Edit the hatch’s reference scale in Hatch Manager. | | Hatch changes unexpectedly | Surface hatch linked to material | Use fills for temporary markup, not permanent drawing. | | Custom hatch not appearing | .PAT syntax error or missing definition | Validate file with a text editor. Only first 255 lines of a .PAT are read. |

Introduction

ArchiCAD is a popular Building Information Modeling (BIM) software used by architects, engineers, and designers to create detailed designs and models of buildings and other structures. One of the key features of ArchiCAD is its ability to create and manage hatching patterns, which are used to represent different materials, textures, and surfaces in a design. In this report, we will explore the concept of "hatch" in ArchiCAD, its uses, and how to work with it.

What is Hatch in ArchiCAD?

In ArchiCAD, a hatch refers to a pattern of lines, shapes, or textures used to fill a closed shape or area in a design. Hatches are used to provide visual representation of different materials, such as concrete, brick, wood, or glass, and can also be used to indicate different surface textures or patterns. ArchiCAD provides a wide range of pre-defined hatch patterns, and users can also create their own custom hatches.

Uses of Hatch in ArchiCAD

Hatches are used in various ways in ArchiCAD, including: Short Story: The Hatch Marco had been an

1. Material representation: Hatches are used to represent different materials in a design, such as brick, concrete, or wood.
2. Texture and pattern representation: Hatches can be used to indicate different surface textures or patterns, such as a wood grain or a stone texture.
3. Section and elevation views: Hatches are used in section and elevation views to provide a visual representation of different materials and surfaces.
4. Documentation and communication: Hatches can be used to create detailed documentation and to communicate design intent to clients, contractors, and other stakeholders.

Working with Hatch in ArchiCAD

To work with hatches in ArchiCAD, users can follow these steps:

1. Accessing hatch patterns: Users can access pre-defined hatch patterns in ArchiCAD by going to the "Options" menu and selecting "Element Attributes" > "Hatch".
2. Applying hatch patterns: Users can apply hatch patterns to closed shapes or areas in a design by selecting the "Hatch" tool and choosing a hatch pattern from the library.
3. Creating custom hatches: Users can create their own custom hatch patterns by using the "Hatch Editor" tool.
4. Editing and modifying hatches: Users can edit and modify existing hatch patterns by using the "Hatch Editor" tool.

Best Practices for Working with Hatch in ArchiCAD

Here are some best practices for working with hatches in ArchiCAD:

1. Use pre-defined hatch patterns: Use pre-defined hatch patterns whenever possible to save time and ensure consistency.
2. Create custom hatches: Create custom hatches only when necessary, and make sure to save them in a consistent location.
3. Use hatch patterns consistently: Use hatch patterns consistently throughout a project to ensure clarity and accuracy.
4. Document hatch patterns: Document hatch patterns used in a project to ensure that all stakeholders understand the design intent.

Conclusion

In conclusion, hatches are an essential feature in ArchiCAD, used to provide visual representation of different materials, textures, and surfaces in a design. By understanding how to work with hatches, users can create detailed and accurate designs, and communicate their design intent effectively to clients, contractors, and other stakeholders. By following best practices and using pre-defined hatch patterns, users can ensure consistency and accuracy in their designs.

In Archicad, "Stories" and "Hatches" (known as Fills) are the backbone of project organization and documentation. While Stories define the vertical levels of your building, Fills provide the graphical representation of materials and surfaces across those levels. 🏗️ Managing Story Settings

Stories act as vertical slices of your 3D model. Setting them up correctly ensures that elements like walls and columns are linked to the right floor heights.

Accessing Settings: Right-click any story in the Navigator or go to Design > Story Settings.

Adding/Deleting: Use "Insert Above" or "Insert Below" to add levels; use "Delete Story" to remove them (be careful, this is permanent!).

Vertical Linking: You can link wall heights to specific story levels. If you change a story height, linked walls will automatically adjust.

Markers in Sections: Story levels automatically generate markers in sections and elevations. You can customize their look, font, and units (e.g., changing from feet to feet-and-inches) in the Level Dimensions preferences . 🎨 Working with Hatches (Fills)

In Archicad, hatches are officially called Fill Types. They are used for 2D drafting, surface textures, and section cuts. Four Types of Fills: Solid: Single color with adjustable opacity. Vector: Preset line patterns (cannot be easily edited).

Symbol: Custom patterns you create by copying and pasting lines/arcs into the Fill dialog.

Image: Uses JPG or PNG files for realistic textures (like grass or stone).

Availability: You can set a fill to be available only for specific uses, such as Drafting Fills (2D only), Cover Fills (visible on top of objects in plan), or Cut Fills (visible in sections).

Hatch Origin: If patterns aren't lining up, check the "Hatch Origin" setting. You can set it to align with the element or the project's zero point. 🛠️ Displaying Elements Across Stories

A common challenge is showing an element (like a roof or stairs) on multiple stories. Hatch patterns for "earth" and 'story setting displays'??

Mastering the "Hatch" in Archicad: A Guide to Fills If you are coming from an AutoCAD background, you probably keep looking for the "Hatch" command. In the world of , we call these

. While they serve the same purpose—adding patterns, textures, and colors to 2D regions—Archicad’s Fill tool is deeply integrated into the Building Information Modeling (BIM) workflow.

Here is everything you need to know about mastering "hatches" in Archicad. 1. Understanding the Four Fill Types

Archicad categorizes fills based on how they behave and what they represent: Solid Fills

: These are simple, mono-colored fills. You can adjust their opacity (e.g., a 25% or 50% screen) to create depth or highlight specific areas. Vectorial Fills

: These are standard hatching patterns (like bricks or cross-hatching) made of 2D lines. They are perfect for technical documentation. Symbol Fills

: These allow for more complex, repetitive patterns. A pro tip is that you can actually add fills directly inside Symbol Fill definitions

to create richer textures without layering multiple elements. Image Fills

: These use actual image files (JPG or PNG) to represent real-world materials like stone masonry or wood grain for high-end visualizations. 2. How to Create and Edit Fills To manage your "hatches," navigate to Options > Element Attributes > Fill Types Customizing Patterns

: You can create your own patterns by drawing a small segment with 2D lines, copying it, and pasting it into a new "Symbol Fill" definition. Adjusting Orientation

: Unlike basic CAD programs, Archicad allows you to set a "Fill Handle." This lets you manually rotate or change the origin of the pattern directly on your floor plan or section to align with specific walls or edges.

: If a pattern looks too dense, you can adjust its scale within the Fill Types dialog or use the "Scale with Plan" vs. "Scale-independent" settings to decide if the hatch should stay the same size regardless of your zoom level. 3. Why Fills Matter in BIM

In Archicad, a "hatch" isn't just a 2D decoration. Fills are often linked to Building Materials

. When you draw a wall in 3D, Archicad automatically applies a specific Fill pattern to its 2D section cut. This ensures that your technical drawings are always consistent with your 3D model. Pro Tips for Better Documentation Cover Fills

: Use these for surface finishes on elements like slabs or roofs to show floor tiling or roofing patterns in a top-down view.

: These automatically appear when an element is "cut" by a section or floor plan cut plane, representing the internal material (e.g., concrete or insulation). Graphic Overrides

: Use these to instantly change the appearance of all fills in a view—for example, turning all wall fills solid black for a clean presentation style.

Whether you're drafting a simple floor plan or a complex detail, mastering Fills is the key to clear, professional architectural communication. from AutoCAD into Archicad?

The story of the ArchiCAD Hatch (known formally as the Fill Tool) is one of evolving from simple 2D drafting lines into an intelligent, 3D-aware component of Building Information Modeling (BIM). Here is the narrative of the ArchiCAD Hatch: 1. The 2D Dawn (Drafting Era)

In the early days, ArchiCAD users, much like their AutoCAD counterparts, relied on hatches solely for 2D representation. A hatch was just a collection of lines filling a closed area—a "sand" hatch for concrete, or angled lines for brick. These were manual, static, and disconnected from the model's intelligence. 2. The Rise of "Vector Fills"

ArchiCAD introduced Vector Fills, allowing fills to have a specific orientation and to change scale based on the view scale (

). The hatch grew intelligent; it understood that the concrete pattern should look denser on a small-scale plan and sparser on a large-scale detail. 3. BIM Integration: "Fills in 3D"

The biggest transformation was connecting the 2D hatch to the 3D model.

The Magic Wand: Users can now use the "magic wand" tool to automatically detect the boundary of a wall or slab and fill it instantly.

Cut Fills: When a user cuts a section through a 3D building, ArchiCAD automatically applies a "Cut Fill" (hatch) based on the building material assigned to that element. 4. The Modern Era: Symbolic & Image Fills Today, ArchiCAD hatches are advanced:

Symbol Fills: These allow users to create complex, custom, line-based patterns (like intricate floor tiling) that repeat perfectly.

Image Fills: These map real textures (like custom flooring or specialized cladding) directly onto 2D drafting elements.

Graphic Overrides: Hatch patterns are now dynamically changed based on rules (e.g., highlighting all fire-rated walls with a specific pattern). 5. The Current Conflict: The Need for "Model" Hatches

Despite these advancements, users still demand better, more realistic hatch patterns that match modern rendering capabilities, often looking at ways to import custom .PAT files (common in CAD) to improve the stock collection. Importing an AutoCAD .PAT file into ArchiCAD?

Mastery Guide: Archicad Hatches (Fill Types) In Archicad, "hatches" are technically known as Fill Types

. They are essential 2D elements used to represent building materials, highlight specific areas in plans, or add depth to elevations. Unlike basic CAD hatches, Archicad fills are highly versatile, ranging from simple solid colors to complex, symbolic vector patterns. Types of Fills in Archicad

Archicad categorizes fills into four distinct types to suit different drafting needs: Solid Fills : Simple, single-color fills. You can adjust their (e.g., a 66% solid fill) to create overlays or masks. Vector Fills

: Patterns made of preset vector lines, often used for standard architectural hatching like brick or concrete. Symbol Fills

: Custom patterns you can create yourself. These allow you to combine lines and even other fills within a single definition for high-detail documentation. Image Fills

: Based on .jpg or .png files, these are ideal for realistic textures in presentations. How to Create a Custom Symbol Fill

If the stock collection doesn't meet your needs, you can easily create your own "hatch" pattern: Draw your pattern

: Use the Line or Arc tools to draw a repeatable "tile" of your design in the 2D window. Copy the design : Select your pattern lines and press (Windows) or Open Fill Types : Navigate to Options > Element Attributes > Fill Types Create New Symbol Fill , and name it.

in the "Edit Symbol Pattern" window. Your drawn lines will now be used as the repeating hatch unit. Working with External Hatch Files Many manufacturers provide hatch patterns in the

format (common in AutoCAD). While Archicad handles these differently, you can integrate external data: DXF/DWG Import : When you open a DWG file

containing hatches, Archicad can convert them into standard Fill Types. Exploding Blocks : If a hatch arrives as an "unnamed group" or block, use Edit > Reshape > Explode into Current View to turn it into editable Archicad lines and fills. PDF Content : You can also explode vector PDF files to extract line work for new symbol fills. Best Practices for Performance

Extensive use of complex hatches can impact your project's speed and export quality: PDF File Size

: Using too many intricate symbol fills can significantly increase the size of exported PDFs, making them difficult to open on mobile devices. Graphic Overrides Graphic Overrides

C. Applying Hatch to Zones (The "Hatch Pattern" for Rooms)

Zones (rooms) use a specific type of fill.

1. Select the Zone.
2. In Zone Settings, go to the Plan Graphics page.
3. Set Show Zone Fill to Fill with Hatching.
4. Choose your pattern (e.g., Zone - Dotted).

Step 3: Edit the Pattern

1. Select your new fill and click Edit.
2. A grid window will appear.
3. Use the Line and Point tools to draw the pattern on the grid.
   • Tip: You can set the spacing of the grid to match mortar joints or insulation spacing.
4. Click OK to save.

Cover Fills for Slabs

A common frustration is that slab hatches appear in Floor Plan but obscure the view in 3D.

• Solution: In the Slab Settings, go to the Floor Plan and Section panel. Use the "Cover Fill" checkbox to display the hatch only on the top surface in plan view, keeping 3D views clean.
