Thumbnail preview not showing in Explorer

[garygoude]

Recently starting having this problem. 1-2 months ago it was not a problem. I am not aware of any system variables being changed.

 

When using the WBLOCK command, no thumbnail preview is being saved with the block for previewing in Windows Explorer. I have check the RASTERPREVIEW system variable is set to 1, but this makes no difference.

 

When saving files normally I do not have a problem. The block previews are very useful for my day to day work, so if anyone can help I will be very grateful. Using AutoCAD 2011.

 

Thanks, Gary

Did you check to make sure thumbnails were set to be viewed in Explorer?

[garygoude]

I'm not aware that this is the problem as general files saved via File>Save etc show their thumbnails perfectly in Explorer. Issue is isolated to files generated using wblock...any ideas?

Were these blocks created with an earlier version of AutoCAD?

[SLW210]

Can you post a file that doesn't have a thumbnail?

[garygoude]

No, not at all. I have been using AutoCAD 2011 since it was released, up to now. It is only the last month or so this has been happening, before this no problems! I can't figure it out. All files are set to save as AutoCAD 2000/LT 2000.dwg, as I have always used to maintain compatibility with my clients older systems. Like I say, this is a recent problem, 2 months ago it was fine....

Access to your files are blocked at my work.

 

Use "Go Advanced" then "Manage Attachments" to post directly on CADTutor.

ahh, sorry, didn't know this is how to do it....all still a little new this forum...ok

 

 

wblock test file 01.dwg

I can't get any of my drawings to show a preview in Windows Explorer, I checked all settings in Windows I could think of.

 

Previews fine when opening through AutoCAD. PDFs etc. Preview in Explorer, though I did notice a couple of random PDFs that had no preview.

Its a strange one, I dont understand why its only just started happening. The wblock files dont even preview in the AutoCAD "open" dialog box. All regular files are fine though. Prior everything used to preview and thumbnail in Windows Explorer. Looks like I will have to live with this then! Appreciate your help guys, if you happen to have any other thoughts, im all ears!

And here I thought I was the only one.

 

I don't get previews when searching for a drawing to open in AutoCAD 2013 at work (Win7 Pro) but I do at home using Win7 Ultimate.

[garygoude]

Its crazy, there got to be something slightly unstable in AutoCAD, we are only a small design office with 6 stations. Each station has its only slightly strange problem with AutoCAD. Mine has the issue with previews, another has its crosshair freeze dozens of times during the day, another the snap intersection doesn't work, and lots of other little things one station has and another doesn't! I will live with it, as do my colleagues with their issues. Thanks for you help in any case, Gary

Let's not give up so fast there Gary. Where there is a will there's a way.

[garygoude]

Haa, ok I won't give up just yet then! I changed a few system variables a couple months back, but they was tweaking the visual performance actually operating AutoCAD. I was testing to try improve another work stations issues. I wonder if these may have had an influence, trouble is I have no record of what changes I made...oops! Going to rack my brain to try remember, any ideas in the meantime I'm all ears!

[ReMark]

Not to worry. If I run across anything of interest I'll be back.

Öhm, there is a thumbnail in your picture. But it shows only your "Blank-Model-Backround" half page and the rest is white, isn't it?

 

Ithink my picture explains it (only tested with Acad 2012 and 2013).

 

Before -wblock did you use zoom extend and save that drawing.

 

If I'm wrong ... Sorry

[garygoude]

Hi KFW, appreciate your input, I have just spent a few minutes trying this and other zoom positions and still nothing the thumbnail I get is still cream arrghh! Thank you though!
