Drawing Angular Gradients on a Circle Edge

[cmoher3]

I'd like to draw and possibly 3D print a round disk, say 6 inches (15 cm)in diameter and have the angular gradients , in 1 degree increments, drawn , or etched, in the case of a plastic 3D print, in the outer 1/4 inch (0.5 cm) of the disk. Can one of you kind people tell me if there is an automatic function, within fusion, to draw or map these gradients on the circle, without the extreme labor of 1 line at a time ? If I could further trespass on your generosity, I'm also curious as to how one can get fine markings etched into material, by fusion , for 3D printing.

Not so automatic, but not hard to do, 

Sketch the face of the disc, add the first nine 1 degree divisions, as you desire with a sketch pattern, 

I did a long 10, and shorter 5 mark, but whatever suits. (Read the timeline - mirrored the four short ones)

Then use pipe (cut) to get the first 9 divisions, on the face, 

Then Model Pattern the set 36 times.

Might help....

Thanks as always Dave. I'll add scalable gradients to my wish list for future Fusion releases. They are needed an awful lot. With 3D printers, makers are going to town printing all those missing knobs from their antique collectibles, as but one example.

I've opened an "Idea" suggestion "Scaleable Gradient Templates For Linear and Angular Measure" for future versions and certainly would welcome any support. As one fan has already said, this tool could work on flat surfaces or wrap around knobs or barrels as well as do linear gradients of variable markings with etchings.

My point in studying Fusion is to make 3D prints. I can see Dave has mapped these markings onto the drawing but am curious to know how that gets put on the actual object ? Are there small etch marks ?

The sketch contains the centre lines of the pipe bodies.  The pipe tool is similar to Extrude, has a New Body, Join or Cut, in my example, I used the sketch on the face of the disc, cutting half round tubes with Pipe > cut.  Pipe command is limited to solid or hollow cylindrical bodies.

To make a cut of another shape,  you need a second sketch for the shape profile, to use the Sweep command.
