Imagine a stereo system or complex piece of test equipment with no front panel markings. This makes the silk screen as critical as the switches themselves, without silk screened labeling the product is useless.
In the product referenced in this workflow, the heavy lifting is done on the printed circuit board. This is where all connectors and controls are positioned. For electronics packaging this is often the norm, but even if it were not, outside control markings are so important they would be considered if the case were designed first then used to position the parts on the printed circuit board.
Fusion 360 is then used to enclose the printed circuit board. I selected an appropriate off-the-shelf enclosure (in this case Hammond 1590XX) then positioned the board in the enclosure, projecting the mounting holes and the holes needed to expose connectors, indicators and controls. Very nice, slick and fast workflow. A humble EE with absolutely no training in this or any other 3D tool was able to do it.
The final step is to create a drawing to make the silk screen that will label these controls. It's natural to start a new sketch on the face of the surface to be screened, then just use text to put the labels in. You can size the font to fit nicely with the controls and you can move it where it is best from an ergonomic and artistic perspective. I put the silk screen sketch together in less than a half hour.
And then in Fusion 360 you hit a brick wall: all this beautiful text is mashed by the outline output. It's useless, can't be sent to anyone to make a silk screen. So we're back to using Visio or some other silly tool to, by-eye, make a suitable silk screen master. Mistake-prone? You bet. A big waste of time.
If a good silk-screen output to PDF were included then Fusion 360 is truly a one-stop shop for EEs trying to package electronics.
