If you have any conditions in Vector that it seems to be operating
incorrectly, you should post and/or search on the Vector user's forum.

1) The development team reads the posts and listens.
2) You will probably find the answer to your problem already handled
with an update, or a method to accomplish what is causing you problems.
3) You will get an answer faster.

Any gaps larger than the general accuracy should show up, but small
entities with more than one within the general accuracy may not, indecisive
loops and intersections may also be a problem, as well as duplicated
geometry. This is particularly a problem with programs that have a poor
DXF conversion capability, like Corel Draw. Also remember that when you
scale a DXF drawing, the chain gaps also scale. Make sure that you trim
into chain after any scaling operation that increases the scale in any
axis direction. It may help to reorganize if you scale to a smaller size, as
it can eliminate any entities that appear to occupy the same chain gap space.
