Trace follow question / request

I use ‘Trace follow’ to create chamfers on my parts. In some cases, the chamfer follows an edge with varying heights, meaning the chamfer goes up and down. The problem is that the Trace operation only seems to generate a horizontal toolpath; it doesn’t follow the Z-axis variations of the path.
Is there a way to do this differently ?

I feel like it would be really useful to have a Trace operation that precisely follows a path, including its variations in altitude.

if you set step down to 0 it will follow the Z

Oh ? That’s right, that’ll be very useful, thx !

I just tried, and if you try to input an offset (Inside, Outside or Z), it does not follow the Z though.

correct since the offsetting logic is 2D. I would need to raster the path to recover the 3D path and take into account the tool geometry. it’s doable but will require a lot more work. if you file a github issue, it’ll help me remember to do this when I have time.
