Before you hatch Model or drafting
A model pattern is a material at its real size; a drafting pattern is a symbol at a fixed size on paper. Every card says which one it is.
Model
Bricks, tiles, planks, ceiling grids
Drawn in real millimetres or inches. Hatch at scale 1 in a drawing in the same units; in Revit it scales with the view like the wall it sits on.
Drafting
Concrete, earth, insulation, section lines
Drawn for paper, ⅛ in between section lines as in ANSI31. In AutoCAD set the hatch scale to the drawing scale; in Revit it stays the same size on every sheet.
Load them in AutoCAD, Revit or Bluebeam
AutoCAD & LT
- 1Put the .pat files in a folder, for example C:\CAD\Hatch.
- 2OPTIONS, Files tab, Support File Search Path, Add, browse to the folder, OK.
- 3Type HATCH. The patterns are in the pattern gallery under their names; restart AutoCAD if they are not.
- 4Model patterns: scale 1. Drafting patterns: scale = drawing scale (50 for 1:50, 48 for ¼ in = 1 ft).
Revit & LT
- 1Manage, Additional Settings, Fill Patterns.
- 2Pick Drafting or Model to match the pattern's type, then New, Custom, Import.
- 3Choose the file (all-metric.pat from the ZIP lists every pattern at once) and the pattern.
- 4Import scale 1, OK. Use it in a material's surface or cut pattern, or a filled region.
Bluebeam Revu
- 1Draw any rectangle markup, then Properties toolbar, Hatch, Manage.
- 2Select a hatch pattern set and click Modify.
- 3Click Import AutoCAD Pattern and open the .pat file.
- 4OK to close the dialogs. The pattern is now in the Hatch list.
One file with every pattern: all-metric.pat · all-imperial.pat. Good for Revit's import dialog and for pasting into acad.pat; AutoCAD's Support File Search Path wants one pattern per file, which is how the ZIP and the buttons above give them.
Questions About concrete hatches
What is the standard concrete hatch?
In section, concrete is drawn as stipple dots with small triangles for the aggregate; AutoCAD's own version is AR-CONC. Many offices add 45° lines to mark reinforced or structural concrete, which is what CONCRETE-REINFORCED does. In elevation and plan, plain stipple or nothing at all reads better.
Why does the concrete hatch look too dense or too sparse?
They are drafting patterns, drawn for paper like ANSI31: set the hatch scale to the drawing scale (50 at 1:50, 48 at 1/4 in = 1 ft-0 in) in AutoCAD. In Revit a drafting pattern follows the view scale on its own. If it still looks wrong, the file was probably loaded with the other unit: a metric file read as inches is 25.4 times too big.
Can I use these concrete hatches in Bluebeam?
Yes. Revu imports AutoCAD .pat files: on the Properties toolbar go to Hatch, Manage, pick a hatch set, Modify, then Import AutoCAD Pattern and choose the file.
Do the same files work in AutoCAD and Revit?
Yes. Each file is a standard .pat with Revit's ;%UNITS line at the top and a ;%TYPE line under the pattern name. AutoCAD reads both as comments, Revit reads them as settings, so one file serves both. There is a metric and an imperial copy of every pattern.
Should I take the metric or the imperial file?
The one in your drawing's units. A model pattern is drawn at real size: in a drawing in millimetres, the metric brick hatched at scale 1 shows real 215 × 65 mm bricks; in a drawing in inches the imperial file does the same. Revit reads the units from the file, so either works there.
