The installer also installs the Navisworks plugins for you. Make sure you’ve closed Navisworks before installing. If for some reason the Navisworks plugin hasn’t been installed correctly you can do this yourself.
Manual Navisworks plugin install
To install the Navisworks plugin yourself go to the menu in the script Menu > Navisworks > Install Navisworks plugin. The script will now attempt to copy the Navisworks plugin to the appropriate folders in the user-profile. Depending on some factors this might succeed or not:
UAC settings in 3ds Max: strict windows settings prevents 3ds Max from copying files to certain locations. Running 3ds Max in administrator mode helps.
Has Navisworks itself been installed? You need Navisworks to actually export the Timeliner data.
Make sure to close any NavisWorks program you might have opened.
Check the log window in the script to see what’s going on.
Add a button on a toolbar
To add the script to a toolbar, use the menu: Customize > Customize User Interface... Go to the “Toolbar” tab and in the “Category” list pick the “Klaas tools” item. A list of scripts in that category appears. Pick the “Navisworks Timeliner [version number]” item and drag that to an existing toolbar or make a new toolbar for it. Save the ui layout if you want to keep it.
You can also put the script in a menu, quad, under a keyboard shortcut or a combination of these.Check this video and blog post to see how it’s done.
