So I've been making some custom hatch patterns so that we can use tram and ladder tactile paving in our design. I've gone through making a hatch pattern using notepad, and the preview shows as it should when loaded into CAD but it appears as a solid hatch when used even at different scales (0.01-100).The notepad file reads as such:*LADDER, ladder type0, 0,0, 0,4, 4,00, 0,0.35, 0,1, 4,00, 0,0.65, 0,1, 4,090, 0,0, 4,0, 4,0The preview and hatch are shown below

Hello ASteel, have you tried to change the scale, what I read on your screen to be the number : 32 ( maybe it's the color ? ) or 1.000 ( scale ? ).

Hi,The 32 is the colour. I've tried multiple scales ranging from 0.01 to 100, and the pattern doesn't change.

Hello ASteel, eventually select the hatches and open the properties pannel ( Ctrl+1 ) to take a look at all the settings.

Here are the properties for the hatch, but nothing seems amiss with them?

ASteel, I see :Line type scale : 1.000 try and changeScale : 1.000 that you have tried to changeSpacing : 1.000 but it's in gray maybe not to be changed ?ISO pen width : 1.00 mm but it's in gray maybe not to be changed ?

I see that 32 is not the color of the pattern, but the background color.  Try turning off the background.
BUT WAIT --AutoCAD is telling me there's an error in the pattern definition.  I see you have no pen-up negative-number entries, which suggests all the lines are meant to be continuous.  If that's the case, you need no pen-down-pen-up entries at the ends of the lines of code.  And a lineset with zero for the Y offset is meaningless, offsetting its lines on top of themselves.  The X and Y of the offset values are not the drawing's X and Y directions, but in relation to the angle of the lineset being the X direction.  When I change the last line to:90, 0,0, 0,4, 4,0it works, giving me this:Is that what it's supposed to look like?  If not, draw what it should look like with Lines, and post an image.If so, and they're all meant to be continuous, as mentioned you can omit the  , 4,0  at the end of each line -- they serve no purpose if there are to be no gaps, and if there are to be gaps, a negative number is needed.

[The reason Spacing is grayed out is simply that it's applicable only to User-defined patterns, the same as the Double option.]
