The Rhino BETA has a more subtle approach to notifying you when there is missing content in your file than previous versions of Rhino.
Any missing content warnings are now grouped or combined into a single dialog.
What is the Missing Assets dialog?
The new Missing Assets dialog combines messages for:
- Fonts
- Images
- Linked block definitions
The dialog boxes for the missing content are no longer displayed automatically when opening a model with missing fonts, images and linked blocks.
Instead, a warning icon appears in the status bar. 
A short tooltip also pops up above the icon for a few seconds when the model loads, so the missing content is easy to notice. Clicking either the icon or the tooltip opens the Missing Assets dialog.
Why was the Missing Assets dialog added?
Opening a file that was once edited on a different computer could open the flood gates to a plethora of dialogs that had to be interacted with by the Rhino user. Even passing a model from a Mac Rhino to a Windows Rhino would introduce “missing font” warnings.
Missing content can be fonts, images and linked block definitions, and many times a file has all three types of content missing.
This feature was requested by many customers over the years since linked content had become part of the Rhino model.
Previous Rhino presented the user with many separate dialogs when opening a file with missing content. All the dialogs required a response or input, or you could select Apply to All. Still, this could be time consuming and frustrating to Rhino users.
How does this work?
In the Rhino BETA, open a model with missing fonts, images and linked block definitions.
You now have the option to either begin modeling immediately or to investigate missing assets.
- If it is important to check what is missing and navigate to it, then the dialog is accessed by picking on the yellow alert.
- If not, then you can go right to work on your model.
Clicking the icon will open the dialog box shown above.
Alternatively, you can also access the dialog box from the menu under “Tools → Missing Assets…” or by typing the MissingAssets command.
Resolving missing assets
The Missing Assets dialog doesn’t just report what’s missing — it lets you fix it. Fonts, images and linked blocks each have tools to relink or collect the content:
- Replace — point a single missing item at a new file.
- Bulk Replace — search a folder you choose and update every item whose file name matches, in one step.
- Gather — copy the selected items into a folder you choose and update their paths, so the model and its assets can be handed off together.
The list refreshes as you go, so you can see what’s still unresolved.
Note: the MissingAssets command replaces the older
RenderReportImageFilesandRenderReportMissingImageFilescommands, which are now hidden in V9.
thank you for those improvements
