What is a plaster hatch?

A plaster hatch is a fine stipple pattern used for thin applied layers such as plaster, render, screed and sand blinding, where no coursing or grain exists to draw.

How do I import a plaster PAT file into AutoCAD?

Place the .PAT file in a support path, run HATCH, choose Custom and select the pattern. Keep the hatch scale at 1 and check the density prints correctly before issuing.

Can I use this plaster hatch in Revit?

Yes. Import it as a Drafting fill pattern so the stipple density stays readable at every view scale, which matters for thin finish layers.

Can I change the scale?

Yes. Reduce the pattern size for very thin layers so several rows of stipple still fit inside the layer thickness, and increase it for sand beds.

About the sand / plaster hatch

Plaster, render, screed and sand share the same drawing convention: a fine even stipple. It marks a thin applied layer that has no internal structure worth drawing, unlike masonry or timber.

In a wall section the stipple is often only two or three millimetres thick on the page, so the dot spacing has to be tight enough to register when the sheet is printed at A3.

Use it for internal plaster finishes, external render coats, sand blinding under slabs and floor screeds. Adjust the pattern size to the layer thickness, then export the PAT file for AutoCAD or import it into Revit.

How to use the PAT file

Download the .PAT file, or copy the definition into your own pattern library file.
AutoCAD: place the file in a support path, then choose Hatch, Pattern type Custom and pick the pattern name.
Revit: Manage, Additional Settings, Fill Patterns, New, Custom, then import the .PAT file and set the import scale.
Metric patterns assume millimetre drawing units; imperial patterns assume inches.
