I’ve not been able to hatch a simple Brick pattern at a scale of 1/10 on anything larger that 500 mm x 500 mm.

*Scale of 1:1 works fine
*Scale of 1/10 works fine on Squares 400 mm x 400 mm or less!

To reproduce:
1. Draw square of 500 x 500 mm.
2. Select and execute Hatch command using Brick pattern (but I suspect the result will be the same with any pattern).
3. Result in selection states a Hatch but no hatch is present!

Please see attached image:

Edit: Should read scale 1/20, but I have noticed that on some larger areas a scale of 1/10 is not working either!

Is there a limit in the size area for using hatches in general in QCAD?

There is a timeout of 5 seconds for generating a hatch. This is to make sure the program does not freeze for hours if the user enters for example a factor of 0.0001.
The timeout can only be adjusted by editing the QCAD configuration file directly at this point. In section 'GraphicsView', add a value for MaxHatchTime, for example for a timeout of one minute (= 60 seconds = 60000 milliseconds):

MaxHatchTime = 60000

The configuration file is called QCAD3.ini or QCAD3.conf and under Windows located under C:\Users\username\AppData\Roaming\RibbonSoft\
