Extra lines in drawing

[pmcdonough]

I recently installed 2015LT and every drawing I open has a spider's wed of lines running accross the entire drawing (see attachment). I've narrowed it down to text, if I turn off the text layers the lines disappear. This also happens on new drawings. It's been quite a while since I last used Acad so I'm assuming I'm missing something simple.

That drawing looks fine to me. Can you attach a screenshot of yours?

This should make more sense

Sorry, no such lines like that here either: try turning off LINESMOOTHING variable and even changing LT2015's hardware acceleration settings and see if that helps.

I did get a proxy notice: is this file from another version of AutoCAD? Looks like from AutoCAD Mechanical. I deleted them in AutoCAD 2015 for you and 'flattened' the file content.

Oh, there is a new patch for LT2015: install it and see if it helps at all.

Hello

+1 with Dean

In theory, the SP 1 for ACAD LT 2015 must solve this display problem !?

And please don't hesitate to update your graphic card driver ...

Have you tried to turn off graphic acceleration?

Type GRAPHICSCONFIG then enter. In the dialog, click the graphic acceleration switch.

Click OK, then see if it can solve the problem.

Slightly different problem with AutoCAD Architecture 2015- cursor trails, the cursor staggers across the page etc., the new select has epileptic fits.  I was directed to turn off hardware acceleration as well.  So, do not have this problem with other programs or previous editions.  I am running an nVIdia quadro 2000M, 16 gigs, of RAM and i7 processoer in a W520 laptop.  Not a shabby machine.  I can run ACA 2015, 3DS and PS6 at the same time, open and cranking so it's not the BOard, its the programming in ACA 2015.  What gives?  What changed?  Why do I have to run without hardware acceleration?

2015 abuses video cards and their drivers even more that before, and seems to be creating havoc on laptops at the moment. Until a driver from Autodesk or nVidia fixes it that seems to be the easier solution at the moment.

I am new to using a Forum and I don't that much about autocad.  But, I tripped over this reply you gave someone else and it worked for me.

Thank you!!!
