Concrete hatch fixed

[eldon]

A long source of dissatisfaction has been the appearance of the concrete hatch when it is used far from the origin. When hatch patterns involve square roots and angle trigonometric functions, there is need to define lengths and angles with as many decimal places as possible, whilst remaining within the line length of 80 characters (spaces count as characters).

 

So I revisited the concrete hatch patterns supplied with AutoCAD. I have already posted the imperial concrete hatch pattern definition, and here is the metric version.

You can either copy the definition and replace the supplied pattern in acadiso.pat or use it as a stand-alone hatch pattern.
