Viewport Rotate causes Images to disappear

MeganLoock — Fri, 08 Sep 2017 08:39:26 GMT

Hi there,

This is the first time having this specific problem and we haven't found the solution yet.

All relevant Xrefs attached in model space, paper space setup with plan and profile viewports.

If plan viewport is not rotated the image displays fine, as soon as I rotate the plan layout then the image disappears.

I have used varies methods ie MVSetup, UCS Rotate and Align Space under Express tools. The function gets carried out correctly and the rotation takes place but no image (ECW) as background.

If anyone has another solution or some settings I am unaware of please share.

Thanks All.

Hi and Welcome to AutoCAD Forum,

does this will happened if you attache the image in a new CAD drawing then you rotate the vp ? is it available please to attache your CAD drawing here for testing ?

Regards,

Thanks for your reply. I have gone that way as well and it did not work.

The files don't want to load as I suspected due to the ECW being to large.

Any other solutions I can try?

What version of AutoCAD are you using?

There was a hotfix released for ECW files, although that was to resolve an issue different from what you are experinecing.

https://knowledge.autodesk.com/search-result/caas/downloads/content/autodesk-C2-AE-autocad-C2-AE-2014-2017-ecw-hotfix.html

I would recommend, insert all of your stuff in MS like normal, then go to paperspace, create your viewport using the MVIEW command, get the area close to what you want and scale, then from double clicked inside the viewport run the command DVIEW, you can then hit enter to select everything, TW for twist, and the angle you are looking for.

Hi Christopher,

I am using ACAD 2018, checked the hotfix and it only goes up until 2017.

I applied the steps you recommend, it still does not show the image. What I have noticed though is is yo rotate within the VP at 90 degrees then it works fine and everything shows. Its only when you rotate at different angles that the image disappears.

When the image disappears, See XREF properties(command is XREF).

If the image status says Not found, Reload it and change its path to full path.

have you tried turning off Hardware Acceleration? We can start with the full setting, and then reduce from there if we find that it fixes it.

GRAPHICSCONFIG is the command.

I'd recommend start at the top, shut it all off, if it works, then you can turn it back on and start unchecking boxes.

based on the size of your image I do not believe that is the cause, we've had much larger images that we've attached here and I dont believe we have had this issue (or at least none of my users have said anything about it)

Sad to say that it did not work. Switched it all off and still no luck.

I know, its not a big file at all. I have reverted to working on another CAD platform as there are no issues. The problem is that this needs to be done in ACAD as soon as I can resolve this problem.

Your screenshot appears to be of a civil drawing, are you using straight AutoCAD 2018, or Civil 3D 2018? I've tested in Civil 3D 2018 with some ECW files we have here and rotating the view to odd angles works as expected with the image. I've also tested in AutoCAD 2018 and I'm not able to reproduce this either.

Do you have all of the updates installed for AutoCAD 2018? 2018.1.1 just was released earlier this week. I dont recall this being an issue, but at least it would make sure that you are running the same version of the software I am testing on.

Hi Chris,

Apologies for the delay in responding. I have a Autodesk Civil 3D Package installed. What I used trying to create that specific dwg was Civil 3D as AutoCad -

(Refer to insert). Will this make any difference as to why its not working?

@MeganLoock hello, attached image as attach image in the external reference. see screencast if this is the solution you looking for? hope it helps. thank

MeganLoock — Thu, 14 Sep 2017 10:51:07 GMT

Thanks so much for the video, it does help a lot.

My rotation within the VP works fine if rotated at 90deg or 180 but fails as soon as I use a rotation at 28deg for instance.

Why will that be?

@MeganLoock hello, it still doesn't work? Don't use OLE it will disappear your image when rotating viewport, use attach image, then go to your paper space > mspace > ucs > z > change value as describe in my screencast. By the way the files that you posted the image is missing. please use etransmit when uploading the files so everyhing is included, so that we can check. thanks

I have this same issue and downloaded the hotfix (using Civil 3D 2016). I have tried .tif and .jp2 and they work fine. When you rotate in any manner (I have tried all of the above steps) the ECW image disappears unless the angle is 0, 90, 180, 270. The hotfix did address an issue where the ECW image was coming in with weird colors and pixilation but does not seem to address the rotation issue.

I do not remember this being the case in 2012 or 2014 but I could be mistaken.

For any who are wondering the advantage of using an ECW is that it takes a raw image that's maybe 2-3GB and compresses it to 300-400MB with minimal loss which really increases drawing performance in cad.

chriscowgill7373 — Mon, 18 Sep 2017 15:55:02 GMT

no, I was just confused, because MAPIINSERT is not a command that is available within regular AutoCAD. I'm at a loss on this one, short of seeing the actual drawing and image file, downside is I dont think you can upload a 300 mb image here.

Did you take a look at this similar thread: https://forums.autodesk.com/t5/autocad-forum/ecw-image-amp-rotated-viewport-image-wont-show/td-p/5860728

perhaps your ecw file was created the same way.

I had the exact same issue. The solution I have been using is 'Perspective' and it's either 1 or 0 (the opposite one). Works for me - please let me know if there's a better way!
