Boundary command

I exploded the polylines into lines. I also reduced the lineweight to 0, but in both cases the result remains the same.
A colleague who still has an old PC with Autodesk Map 5 (= AutoCAD 2002) also confirmed that the same error occurs.
If I’m not mistaken, AutoCAD 2002 is basically the same as AutoCAD 2000, so @SLW210’s statement that the "boundary" command works correctly in that version intrigues me.

 

Yes, 2000i fails when zoomed out as well.

The only "solution" besides zooming in I could determine, was to copy the polylines in place and use region on them, which seems to be correct in the example drawing.

 

That should be able to be done with a LISP?

Was reading up on this too. apparently AutoCAD boundary command doesn't have a tolerance setting but BricsCAD does. That is why people opt to use hatching and then you can create the boundary from the hatch. and then delete the hatch. 

 

I'm confused since their isn't a gap/vertex at that location.
