JTB FlagStone

"Flagstone (flag) is a generic flat stone, cut in regular rectangular or square shape and usually used for paving slabs or walkways, patios, flooring. The name derives from Middle English flagge meaning turf, perhaps from Old Norse flaga meaning slab or chip."

Drawing a flagstone layout is a time consuming task. A chosen set can have up to 12 sizes. The pattern must look random and following strict rules:

1. No more than 4 tiles sit on a row (or a column), except at the boundary edge of the area.

2. 2 tiles in a row next to each other should be different size

3. No 4 tiles have their corners meet each other

Following these rules here is an example of the generated flagstone pattern. 

There is no "hatch" pattern available in AutoCAD to do this. The array command is useless in this case. But for now, luckily, we offer the FlagStone command.

FlagStone command will ask you to select polylines and generate flagstone layouts over each one. It is not perfect. Each result is just a proposal, randomly generated. Sometime, it fails to find the tile to continue and stop. You have to run it again and again and choose the best layout. You might also have to adjust and combine layouts to create your final one. But for sure, FlagStone command will save you a lot of time since 90% of the task is automated and done.

General Usage Instructions

• Start the app from the Add-ins tab on the Ribbon or with the command FlagStone.
• Select a set of flagstone size. As you know, the set should be large enough. The more size you choose, the more option you have to fill the layout properly.

• Then you will be asked whether you want a Rectangle layout, or a "Freestyle" layout. A rectangle layout will have 4 straight edges and flagstones on those edges will be aligned to fit. Meanwhile, a freestyle layout is just a fill to a polyline area. At edge of a freestyle layout, flagstones are not aligned to fit.
• Next, you select polylines. Note that only straight polyline is supported.
• The app will run and you can see its progression window. You can cancel it if it takes too long than expected.

• Once done, the app will bring up AutoCAD TextWindow, show some logs and a quick flagstone size schedule. Then you will know how many flagstone tile of each size are laid.

• The results are like in the screenshots.

Issues

• Often, it happens that the app can't find a right tile to fit in at some position. Then, an error red tile is placed and the app will continue to run.
• The Rectangle layout is the closest one that fit. It depends on the polyline's dimensions. You can adjust it manually, or make another run to find a better result. To get more varying results, you can change the input by shrink or enlarge your polyline some inches. 
• The result layout is a random proposed solution with error tiles marked as red. You should copy the input and run the command 3 or 5 times to choose the best result. You should also adjust the tiles manually where the app fails to find the right tile.

If the selected area is too large this dialog box warning will show.
