Autodesk DWG. This file is a TrustedDWG last saved by na Autodesk application

[Anonymous]

O autocad não abre os arquivos e mostra essa mensagem "Autodesk DWG. This file is a TrustedDWG last saved by  Autodesk application ou Autodesk licensed application", entretanto quando divido a tela do note e o coloco na lateral, ele funciona, mostra o arquivo e pode editar, mas quando maximizo a janela fica tudo preto. já desinstalei, apaguei, baixei de novo e segue com o mesmo problema.

it seems that you have open a drawing saved or prepared with another software . try to :

• Erase command >> type All for selected objects .
• by Shift and select mouse button , select the items that you want to keep ( not to delete ) . 

any changes ?

The AutoCAD doesn't display anything, and i can't draw in a New drawing
because the lines isn't visible.
I saved a drawing and when i opened, the AutoCAD displayed the same

Hi,

>> The AutoCAD doesn't display anything, and i can't draw in a New drawing

So it is not depending on one specific file?

What exactly happen when you start command _LINE ... what does the command-line tell you?

Make sure you are starting with an original AutoCAD template (ACAD.DWT or ACADISO.DWT).

Also make sure your AutoCAD background color is different to the color you use for your new object.
