How do I solve this problem I cannot join basic lines to make a closed polyline as they will not join together. So i tried to use the flatten command which does not work and out puts error below:-
Command Prompt Input/ouput
Command: FLATTEN
Select objects to convert to 2d...8 found
Remove hidden lines? <No>:
A vertex was added to a 2D pline (0) which had only one vertex.
A vertex was added to a 2D pline (0) which had only one vertex.
A vertex was added to a 2D pline (0) which had only one vertex.
A vertex was added to a 2D pline (0) which had only one vertex.
A vertex was added to a 2D pline (0) which had only one vertex.
A vertex was added to a 2D pline (0) which had only one vertex.

Please don't link me to the solution below as it has a duff link.....
What is the error message you get when you try to join the LINE entities before flattening?
Also, suggest running PURGE to purge out zero length entities.
To start with, are the lines all coplaner?
If not, then forget about the flatten command for a moment, and try the old brute force method of flattening them.
After the lines are coplaner - if their endpoints all touch, then the JOIN command should work.
If the endpoints do not all touch, use PEDIT > M > (select) > J > (enter Fuzz distance)
