problems displaying lines with autocad 2017

[zorzo]

Good day to all,
I have a problem with acad mechanical 2017. I practically happen to have overlapping lines i.e. from end line to end line, but zooming to video I see two parallels that continuing to zoom then disappear from the screen.. the problem is visualization but I can't find the solution. work with a work station and the video card is a picture nvidia 4000. the same problem occurs in a laptop, it seems that it is a problem of the acad version 2017.some knows how to tell me how to solve the problem? Do you understand?

Thanks again
greetings
Michael

but are the drawn entities actually two?
Did you check the graphics acceleration?
attaching the file is never a bad thing

Hello thanks for the answer. the problem arises with two superimposed lines, which zooming should always see one since they are superimposed and coincident (bigly they appear 2 flanked). as soon as the problem allegoes the file.
if you have advice are welcome.
Thanks again
Michael
