Some reason,
the line changed into light brown color, and thicker several time than normal.
And sometimes,
it even cannot be deleted.
It is not
only bothered the drafters, but also the administrators.
There is a
procedure to deal with those “Dead lines”.
1.
At first, move the lines to a Test drawing. By this way, the
drafter can continue work on his drawing. And administrator can win enough time
to deal with the problem. Just make sure: disconnected the relation between this line with other
components.
2.
In the test drawing, delete all the information carrying from that
drawing which has trouble.
3.
Normally, there should be couple of runs on this line. Combine all
the runs into one run. It won’t work with the combine command, please directly
drag the line together.
4.
Save the result, then click the line and delete it.
*As I have
deleted the line successfully, so I don’t have the pictures with me know, later
I will paste the pictures once I see the problem again.
