Unwanted dimension lines

[Anonymous]

When I hover over a Dimension arrow and choose the option "flip arrow" to get the arrows to the inside, hideous dimension lines remain on the outside and i cant seem to get rid of them, dont seem to have this problem in regular autocad, any suggestions to rid them, or another way to flip arrows with a cleaner apperance?   Attached a PDF to clarify, thanks.

Hello,

You can also type the command: aidimfliparrow to try any luck.

Besides, are you able to selec the unwanted line? What do you see in Property palette if you select it? Is it part of the dimension?

For further look, it would be helpful if you can share the drawing.
