A good bug report/support request helps developers to understand the report, locate the root cause, and eventually fix this problem.
Ideally, a report should be specific with enough details for a developer to identify the issue. There is no need for several rounds of communication requesting clarification and support files.
One example of a bug report with enough details for a developers to follow the exact steps:
command line: line
when prompted "Specify first point", type in coordinates: 0,0 , and press enter;
at prompt "Specify next point", type in coordiante: @10, 10;
at prompt "Specify next point", type in coordiante: @-10, 10;
in command line, type in command lengthen;
in the option widget within the top widget area, type in length 100 and press enter;
click on the line from 0,0 to 10, 10, close to the 10, 10 end point.
Expected results: the line (0,0)-(10,10) is extended by 50 from the (10, 10) end.
Please attach a test case dxf, when necessary. We probably don't want your classified drawings, but do create some scratches to show the bug you found.
