Autodesk Named User usage reporting

Are you considering what Autodesk plan for Named Users you will go ahead with, now that there will be no more network licenses?

Product usage reporting with user details comes with the Premium plan and Enterprise plan for Autodesk Named Users at an extra cost compared to the Standard plan. With it you can see which individuals are using each product and version, and their frequency of use.

If the usage reporting sounds compelling you might find that the price is much higher for the Premium or Enterprise plans than if you stay with the Standard plans and add JTB FlexReport that together with JTB Process Monitor will give you great usage reporting of your named user licenses.

You can even monitor both the total usage time and the active usage time. You don’t want to lock up a license for a user using the license for a few hours per week or month.

JTB FlexReport with JTB Process Monitor works fine with any of Autodesk’s plans; Standard, Premium, Enterprise and Education. You can also monitor other software of your choice.

If you’re interested, try JTB FlexReport and JTB Process Monitor for free.

AutoCAD THUMBSIZE–DWG thumbnail preview images

Thumbnail previews in the AutoCAD 2013 DWG file format and newer are stored as PNG images and provides higher-quality thumbnail previews in a smaller file size than previous image format did. Image resolution is still controlled by the THUMBSIZE system variable. However, the maximum valid value has increased from 2 to 8. If you do not wish to include thumbnail previews in the drawing you can still use the RASTERPREVIEW (THUMBSAVE) system variable to disable them.

Here is how THUMBSIZE is described in the documentation for AutoCAD 2013: Specifies the display resolution in pixels for all thumbnail preview images. It’s saved in the registry with the initial value 3. Whether preview images are saved in drawings is controlled by the THUMBSAVE system variable.

THUMBSAVE (Save a thumbnail preview image) is also available in OPTIONS dialog box on the Open and Save tab, clicking on Thumbnail Preview Settings. THUMBSIZE is only available on the command line.

The larger thumbnail preview used the longer it takes also to save the drawing so if you really want to optimize size and speed set THUMBSAVE to 0 for off.

The preview size in AutoCAD’s file dialog boxes is only showing max 174x101 in resolution. It’s a pity larger options are not available.

The actual size of the thumbnail also depends on how AutoCAD’s application window is sized. Normally it is much wider than higher resulting in thumbnails that are using max width but less in height.

If the current view is using the 2D Wireframe visual style the max height or width of the thumbnail will be 256 even if THUMBSIZE is higher than 2. I can certainly see a need for a change here in an upcoming AutoCAD version as the preview sometimes makes more sense with 2D drawings.

THUMBSIZE Resolution DWG File Size
N/A N/A 152 KB with THUMBSAVE 0
(only 1 KB less than with THUMBSAVE 1 and THUMBSIZE 0)
0 64 x 64 153 KB
1 128 x 128 155 KB
2 256 x 256 158 KB
3 512 x 512 168 KB
4 1024 x 1024 191 KB
5 1440 x 1440 213 KB
6 1600 x 1600 225 KB
7 1920 x 1920 242 KB
8 2560 x 2560 284 KB

To really see the larger thumbnails I used Windows Explorer’s preview pane.

THUMBSIZE=0

THUMBSIZE=3

Here is a test using a drawing with 3D objects and materials and note how the thumbnail adds up to 9 MB to the drawing. The increase due to the thumbnail depends on how the PNG image is compressed and can in worst case probably be up to 15-16 MB for the largest resolution.

THUMBSIZE Resolution DWG File Size
N/A N/A 1154 KB with THUMBSAVE 0
(1 KB less than with THUMBSAVE 1 and THUMBSIZE 0)
0 64 x 64 1155 KB
1 128 x 128 1186 KB
2 256 x 256 1203 KB
3 512 x 512 1261 KB
4 1024 x 1024 1495 KB
5 1440 x 1440 4472 KB
6 1600 x 1600 5172 KB
7 1920 x 1920 6671 KB
8 2560 x 2560 10277 KB

Here is an example using THUMBSIZE set to 1.
