blacked out view ports?

[KILROY1973]

I have AutoCAD map 3D 2011.

My layout background is white, and sometimes the viewport(s) appear blacked out. I can plot fine, no problems there. It makes it hard to see what I have in my view port. I have removed the viewport and created a new one that will fix the problem approx. 50% of the time.

What causes this? Does anyone know?

Hi,

I have not seen something like that, so I can only guess ...

• graphiccard or driver
• hardware accelerationon/off
• wrong scaling of the vierport compared to think objects like e.g. polylines with width or hatches of type solid
• command REGENALL necessary
• ....

If you have such a drawing, what happens when you close it and reopen it? If the problem persists can you upload such a drawing then?

Thanks for the reply.

I don;t think it's the graphics card or drivers because it only happens every great once in a while.

like now I'm working on a project that has 78 sheets each steet has at least 2 view ports and I only have one that is having this problem. I have created a new layout and the proble move to another sheet. I do not want to have to redo all the sheets.

scaling is OK I've checked, and the sheets print out at the right scale.

regen does not help.

I'm lost!!

Hi,

>> has 78 sheets each steet has at least 2 view ports

Hows the variable MAXACTVP set? (Details look >>>here<<<)

My MAXACTVP is set to 64 and the vport is turned on.

HI,

have you tried to raise this value? I know that the help says "per layout" but I would try that to be sure 😉

The setting is set to the max number of view ports.
