Image disappears in viewport when twisted?

[Anonymous]

While using Civil 3d 2013, Latest update, my image disappears anytime I rotate my viewport with DV twist. Does anyone know a workaround, or has anyone experienced this?

The image is an ECW.

Seems to work just fine for me. I downloaded a .ecw file, imported it using the MAPIINSERT command, and twisted the viewports 

Does this happen with other .ecw files?

Does it happen in other drawings?

Does it happen with the same files on different computers?

I have not tested another .ecw file yet, but it did not effect a jpeg.

I tested that theory in our template, but hine sight says it would probably be better to test it in a seperate template.

I know of two computers it is doing this on and have not went further.

I have temporarily solved my issue by simply downloading a .sid of the same image. I am going to hopeully get back to testing this this afternoon, but i have a job to get out the door kinda quick.

I like your thinking style Brian!

If you post up the .ecw file (or upload to dropbox or similar and provide a link to it) I'll take a look at it when I can. You can also e-mail my c3dplus gmail account.

Here is the link from the website I got it from.

It still seems to work for me:

Go to the view manager dialog box, (View command), find the perspective column, and change your current view perspective from Off to On.  That will allow you to rotate your view, and still maintain the image.

On an interesting note, even if the image does not display to me, It Plots! would that point to video card?

Does "Level of Detail" apply to images?

Not only do you need to set the current view perspective, but you will also need to set the perspective on the actual dwg view, if they are different.

We also had it where the image would not display in the viewport, but would show up in the plot preview, and the plot respectively.  After thinking it was the video card, we eventually realized it was the perspective column in the view manager.

Good luck.
