Walkthrough suggests to me architectural, and there is nothing 'out of the box' in TC. There is a QuickTime movie creation in some versions of TC, (including v16), but that is for creating a 'look around', i.e. in a QT viewer, one can rotate around the drawing to see all sides. a bit like a 3dpdf does nowadays. Note - I've not looked at that in many years so memory may not be exact.
At a cost. One can use the AnimatiinLab plub-in. With this you can set up nearly any animation you require. Though whether the current version will work with v16, I would have to do some tests.
The cheapest options would be, use a third party screen recorder (some are free), to record your screen / window as you move through the drawing, possibly using the walkthrough tools, then edit the recording in a movie creation program, it may take some time to get right but you can edit it to create a good movie. the main drawback would be that one may see the curser in the finished movie.
A second option would be to take a lot of screenshots, then put them all together in a movie creation program, this would be more time consuming, but is quite easy to do. A rough estimate would be, at 25 frames / second = 25 x 30 seconds = 750 screenshots + another 100 that are not used.
Another option would be to export the drawing into another format, and use a third party application like Blender to render and animate.
