If you want to hatch an area whose boundary is not quite closed, you can set the HPGAPTOL system variable to bridge gaps and treat the boundary as closed. HPGAPTOL applies only to gaps between lines and arcs that, if extended, would meet.

Great. This will be very useful. Thanx for the tip.
Cheers

You can change this variable directly in the Hatch dialog box

and if you need it closed.............
I remember seeing a lisp routine somewhere that will draw a circle
around each spot that isn't closed. Anyone have something?

I've got a couple stashed away somewhere if you really want me to find them.Originally Posted by Robert.Hall
one started out as a routine called "Chain".
You touch a line or PL and the routine goes around the "object making sure that all the lines end where the next begins. It changes the color of the line as it goes forward successfully and changes it back when complete. If it finds a gap it ends right there, leaving the line color wrong.
Re: "IF you want to hatch an area whose boundary is not quite closed"
I use PEdit/Join to achieve the same thing. Just change the colour of the first segment before you start.
Re: "IF you want to hatch an area whose boundary is not quite closed"
More or less... The only real difference is it changes back to BYLAYER if enclosed and takes less steps to accomplish the same task.
And we won't even go into me still using PLJOIN.lsp from the 00-02 ETs
Re: "IF you want to hatch an area whose boundary is not quite closed"
I sometimes just offset the pline an appropriate distance. This exaggerates the corners and the open corner will be obvious.
Don't force a closure in the Properties Box, it can create a crossing pline, which can cause other problems with other commands.
Re: "IF you want to hatch an area whose boundary is not quite closed"
I have also used the offset command as you describe. Unfortunately, not all of my
geometry will offset. Some data I receive does nothing with the offset command.

Look for gap.lsp at http://www.spaug.org/LISP_Index99.Html
