Only Solid Hatch Showing In All Drawings

[Anonymous]

I have been having a play around with a particulary large file that I was having trouble with and in the process appear to have made a change that is affecting all files. I am using AutoCAD 2016. The only hatches that are visible in the drawing are the solid hatches. Others appear to be still there as when I use QSELECT I can select them however cant see them. This also happens with any new hatch I draw, only solid ones will work. This is for any drawing that I open. I have found the acad.pat file for 2016 and there haven't been any changes to this file since 2014. Any suggestions would be much appreciated.

One thing I have done to my file was use the command below from the LandFX add on (see link below) but I can't see how this action would affect all files....

PURGE the file recently to try and make it smaller? It might help.

If the problem is with one single file, then ISNERT it into a working blank or template file, explode and test again to see if the problem persists or is gone.

The problem is with any drawing I open now in AutoCAD and any new or template file. This happens with any existing hatch and also any new hatch I do. There is nothing visible at any scale unless it is hatched as a solid....I did try your suggestion below just in case but it hasn't worked....I also regularly purge my files and this hasn't helped either. I have hatched a closed polyline with the AR-CONC hatch at scale 5. Nothing can be seen when I do this but I can select it using the QSELECT command. The properties of this hatch are as shown in the attached screen shot......

I have had more of a play around and it appears there is a problem causing problems with the hatch scales...... I have MEASURMENT set to 1. I can view the AR-CONC hatches if I use QSELECT to select the layer and then change properties to give a background colour. Playing around with a small scale such as 0.0090 shows a solid hatch in the hatch colour (when normally I would set AR-CONC to scale 5) so something makes me think there is a setting I have changed that is causing the scales to be very out....

Found my own solution for anyone that might have this problem in the future.... I had rpreviously reset HPMAXLINES system variable to 100. Restoring it back to the default of 1000,000 has resolved the issue.
