What is a tile hatch?

A tile hatch is a grid pattern representing tile joints on floors and walls. Unlike a generic square grid it is drawn at the real tile module so setting out and cuts can be read from the drawing.

How do I import a tile PAT file into AutoCAD?

Put the .PAT file in a support path, run HATCH, choose Custom and select the tile pattern. Keep the hatch scale at 1 so each cell measures the tile size you entered.

Can I use this tile hatch in Revit?

Yes. Import it as a Model fill pattern with import scale 1 so the grid stays aligned to the floor or wall as you change view scale.

Can I change the tile size?

Yes. Enter any tile width and height, including rectangular and imperial formats, and rotate the field for diagonal or herringbone style setting out.

About the ceramic tile hatch

Tile layouts are set out, not textured. Floor plans, bathroom elevations and finishes drawings all need a grid that matches the tile actually being ordered, so cuts at walls and thresholds can be checked before the tiler arrives.

This generator draws a continuous grout grid at true tile size, starting from a 300 x 300 mm default. Rectangular formats such as 300 x 600 mm and imperial sizes such as 12 x 24 in work the same way.

Rotate the grid by 45 degrees for diagonal layouts, adjust the joint thickness in the preview, then export the PAT file for AutoCAD or import it as a Revit model pattern so the setting out stays fixed to the room.

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.
