Hi,
Observation, QuickView is displaying DWG (CAD) files as hex code.
Viewer Pane displays DWG correctly.
Assuming QuickView is using different plugins than the Viewer Pane?
Directory Opus 13.17.8 (Beta) Build 9355 x64
OS 10.0 (B:26120 P:2 T:1) SP 0.0
Which plugin does the viewer pane say is displaying the file?
(It should be in the viewer pane's tile, in brackets after the filename. You may need to make it wider to see the full name.)
DWG = Shell Thumbnail
DWT = Shell icon (DWT is DWG Template File this one shows application icon)
NWD = Shell con (NWD is Navisworks Document no preview, application icon)
Shell Thumbnails and Icons are only shown in the preview pane, not in the standalone viewer.
(The logic is that images of files obtained that way tended to be low resolution and quality, at least in the past, and would only include the first page of documents. Better than nothing for a small or medium sized preview but not what you'd want if you asked opened the image/document in its own window. These days some of the shell thumbnail handlers extract full-resolution images, making them more useful, but the single-page issue is still there for document formats.)
Heya Leo,
>>These days some of the shell thumbnail handlers extract full-resolution images, making them more useful, but the single-page issue is still there for document formats.)
AutoCAD/BricsCAD both have a Thumbnail preview image size setting, up to 2560x2560
Would this be what DO can tap into?
BricsCAD has a Shell Thumbnail dll
C:\Program Files\Bricsys\BricsCAD V26 en_US\BrxThumbnail.dll
{CBEEF38F-238B-4D96-BD78-428D1F8B0B8F}
Viewer Pane is probably using this but QuickView isn't.
AutoCAD has one to
C:\Program Files\Common Files\Autodesk Shared\Thumbnail\AcThumbnail16.dll
{AC1DB655-4F9A-4c39-8AD2-A65324A4C446}

Any of this of any use to get dwg preview in Quickview?
As above, Shell Thumbnail DLLs are only currently used in the preview pane, not in the standalone viewer.
Found a solution, quite hacky but working.
GStarCAD installs a shell dwg thumbnail previewer 'dwgthumb.dll' to
\Program Files (x86)'Common Files\Gstarsoft
Unzip and copy the Gstarsoft folder to:
\Program Files (x86)'Common Files\
Fire up an Admin CMD.exe
Paste in:
C:\Windows\system32\regsvr32.exe "C:\Program Files (x86)\Common Files\Gstarsoft\dwgthumb.dll"
That'll register the extension, probably need to relaunch Opus.
It'll show up here:
If Model Space Visual Style was saved as 2DWireframe the preview doesn't show much, black background and some faint lines, but if saved with Shaded with Edges then geometry is clearly visible. I'll email their support and let them know my observations an encourage them to update it.
BTW its only dwg not DWT (template files)
