Mastering the Archicad Hatch: A Comprehensive Guide to Fills and Patterns

In the world of architectural design, a "hatch"—referred to in Archicad as a Fill—is more than just a decorative pattern. It is a critical communication tool used to designate materials, show surface qualities, and add a layer of realism to technical drawings. Whether you are a student or a seasoned professional using Graphisoft Archicad, understanding how to manipulate these patterns is essential for creating high-quality Building Information Modeling (BIM) documentation. What is an Archicad Hatch?

While legacy CAD software often uses the term "hatch," Archicad uses Fills. These are 2D geometric patterns or solid colors applied to elements to represent construction materials, such as concrete, brick, or timber. Fills in Archicad are intelligent; they can be linked to physical building materials, ensuring that when you cut a section through a wall, the correct pattern appears automatically. Key Types of Fills in Archicad

Archicad categorizes fills based on their purpose within the BIM environment:

Drafting Fills: Used for manual 2D drawing. These are not linked to 3D elements and are typically used for annotations or simple site plans.

Cover Fills: Applied to the top surfaces of 3D elements (like slabs or roofs) in floor plans. These often represent floor finishes like tiles or hardwood.

Cut Fills: These appear when a 3D element is "cut" by a Section or Floor Plan Cut Plane. They represent the internal material of an object. Advanced Controls: Scale and Rotation

One of the most powerful features of an Archicad hatch is the ability to control its scale and rotation. Unlike static images, Archicad fills can be set to:

Project Origin: The pattern aligns with the global zero point of your project.

Fill Origin: You can manually place a "handle" to rotate the pattern or shift its starting point—ideal for aligning floor tiles with a specific wall.

Distorted Fill: This allows you to stretch or warp a pattern to simulate perspective or custom gradients. Creating Custom Hatch Patterns

If the standard library doesn't suffice, Archicad allows for the creation of custom Vectorial Fills. By drawing a small segment of a pattern with 2D lines and copying it into the Fill Types dialog, you can create bespoke textures that scale perfectly with your drawings. Why Fills Matter in Professional Practice

As drawings move from conceptual sketches to detailed Building Regulations sets, solid gray hatches are often swapped for complex patterns to reflect specific materials. This transition is seamless in Archicad's integrated environment, where a single change to a "Building Material" can update every hatch across your entire drawing set.

While programs like AutoCAD are often cited for their general-purpose ease of use, Archicad’s specialized architectural tools offer more advanced control for professionals who need precision in their material representation.

In ArchiCAD, "hatches" are technically known as Fill Types. Users generally praise ArchiCAD's fill/hatch tools as being significantly more powerful and intuitive than those found in competitors like AutoCAD or Revit. Key Features & User Consensus

Superior 2D Capabilities: Users frequently note that ArchiCAD's 2D tools are exceptionally strong, with some describing the hatch tool as "10,000,000x better" than AutoCAD's.

Versatile Fill Types: ArchiCAD categorizes fills into four main types:

Solid Fills: Simple monocolored fills with adjustable opacity. Vectorial Fills: Patterns made of preset vector shapes.

Symbol Fills: Custom patterns that users can create themselves.

Image Fills: Uses .jpg or .png files for realistic textures.

Placement & Geometry: Fills can be placed using various construction methods (polygonal, rectangular, or oriented) and can be easily adjusted to align with specific element origins, such as tile layouts.

BIM Integration: Unlike basic CAD software, ArchiCAD hatches can be linked to Building Materials, allowing for automatic generation of plans, sections, and elevations while maintaining consistent graphical representation. Strengths vs. Weaknesses

Highly Graphical: Intuitive interface for managing complex patterns.

Deep Learning Curve: Nearly 40 years of development means some workflows can be unintuitive for self-taught users.

Customizability: Allows for easy creation of custom symbol fills.

Resource Intensive: Complex image-based fills can sometimes slow down performance on larger files.

Flexibility: Useful for detailed residential work where "fudging" 2D details is often necessary. Mastering the Archicad Hatch: A Comprehensive Guide to

In Archicad, "hatch" patterns are officially known as Fills. These 2D geometric patterns are essential for distinguishing materials, decorating project elements, and creating professional architectural documentation. Core Fill Types

Archicad offers five distinct fill types to handle various graphic and technical needs:

Solid Fills: Basic single-color fills (Foreground or Background) with adjustable opacity.

Vectorial Fills: Standard hatching patterns used to represent cut surfaces or top covers. They can also be assigned to surfaces for display in the 3D window.

Symbol Fills: Custom repetitive patterns created from 2D lines, arcs, or solid fills. These are ideal for complex textures like pavers or shingles.

Gradient Fills: Purely graphic transitions between two colors (linear or radial), used exclusively as drafting fills to enhance 2D graphics.

Image Fills: Utilizes JPG or PNG images as the foreground pattern, allowing for realistic textures like actual flooring materials in floor plans. Understanding Fill Categories

Fills are grouped into categories that define where they can be used within a project:

Drafting Fills: Freehand 2D fills drawn with the Fill Tool. They are used for annotations and details and do not represent physical construction elements.

Cover Fills: Applied to the top surfaces of elements like Slabs, Roofs, or Zones in floor plan views to represent finishes.

Cut Fills: Used in Sections or Elevations to show the internal structure of elements (Walls, Columns, Beams) based on their assigned Building Material. How to Create and Manage Fills

Mastering the Art of the ArchiCAD Hatch: From Basics to Pro-Level Detailing

If you’ve spent any time inside Graphisoft ArchiCAD (now known as Archicad), you know that a project isn’t just about the walls and windows. It’s about the surface. It’s about the cut pattern of a brick wall, the stippling of a concrete floor, or the diagonal lines of a metal deck.

This magic is made possible by the humble ArchiCAD Hatch.

While it seems simple on the surface (pun intended), understanding how to control, create, and troubleshoot Hatches is a game-changer for producing clean, professional construction documents. Let’s break down everything you need to know.

4. Customizing and Creating New Hatches

Standard libraries rarely have every pattern a firm needs. Here is how to create your own:

Part 1: Understanding the Terminology – Hatch vs. Fill

Before we dive into libraries and settings, it is crucial to clear up a common industry mix-up. In AutoCAD, "Hatch" is the command for patterned areas. In Archicad, the equivalent is the Fill.

However, because the architecture industry is a melting pot of software, most users naturally refer to Archicad Fills as "hatches." If you want a brick hatch, you are looking for a Brick Fill. If you need a sand hatch for a site plan, you need a Sand Fill.

So, what is an Archicad Fill? A Fill is a 2D graphic element that covers a closed polygon, slab, roof, or wall. It defines the surface pattern for plan views (like cut tiles in a bathroom) or elevation views (like the siding on a house).

7. Best Practices for ArchiCAD Hatches

  1. Use Building Materials: Avoid manually applying fills to walls and slabs. Assign the fill to the Building Material attribute. This ensures that if you change the material definition later, all walls update automatically.
  2. Naming Conventions: When creating custom fills, use a prefix (e.g., [Office] Brick Red) so they are easy to find and not confused with default ArchiCAD fills.
  3. Pen Colors: Always set your hatches to use a distinct pen number (usually a lighter weight, like Pen 2 or 3) so they do not overpower the cut outlines (usually Pen 1).

How to Create a Custom ArchiCAD Hatch

Can’t find that specific 45-degree honeycomb pattern your firm requires? Make your own.

  1. Go to Options > Element Attributes > Hatches.
  2. Click New.
  3. Choose Vectorial Hatch.
  4. Give it a name (e.g., "MyFirm_FloorTile_300x300").
  5. You have two ways to input:
    • Grid Method: Define the X/Y spacing and angle. Add line families (Direction, Offset, Line Type).
    • Copy from GDL: If you have a text file with hatch definitions (.pat or .gdl), paste it here.

Pro Tip: Need a complex national standard (like ISO or ANSI hatches)? Don't draw them manually. Go to the Library Manager and download the "ArchiCAD Library 26 (or current version) – Attributes" to import professional hatch sets.

3. High-Performance Pattern Engine

C. Distort Fill

This is a unique feature in Archicad. It allows you to skew the hatch pattern to fit a non-orthogonal shape (like a trapezoidal site boundary) while maintaining the pattern integrity.

Problem 2: "My Image Fill (Texture) is missing / shows a question mark."

Cause: You moved or deleted the original JPG/PNG file on your hard drive. Fix: Archicad only links to images; it does not embed them (unless you use Embedded Library). Go to Fill Manager > Image Fills, select the broken fill, and click Relink to find the image again.
