Archicad Hatch -

In a floor plan, when you cut through a slab, you want a diagonal concrete hatch or a brick hatch.

ArchiCAD 22+ introduced "Distorted Fills." This allows you to apply a fill to a non-rectangular shape (like a trapezoidal site plot) and have the hatch pattern follow the distortion (converge) rather than remaining strictly orthogonal. archicad hatch

| 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. | In a floor plan, when you cut through

The default Archicad library is good, but your local building codes or office standards require specific hatches (e.g., a specific CMU block pattern or a unique stone hatch). You have two ways to create custom Archicad hatches. Click OK

If you just need diagonal lines at a specific angle:

Don’t just pick “brick hatch”. Adjust origin and angle per element. Use the Hatch Alignment tool to make brick courses run horizontally on every wall — even angled ones.

For a clean BIM project, standardization is key:
