can't filet an extruded body to make it look 3D

[ghiggsUVQ9T]

Hi I'm attempting my first 3D cam to cut out on my CNC router table.

I have made a box recessed a pocket in it then brought in a SVG of a rope and laid it on top of the recess.

I then extruded it up. to make the rope look more 3D I want to put a radius on the edges of the rope but it won't 

Please see the attached file and see what you think.

I don't think you will have much success milling this. Some of the internal corners have a radius under .2mm with a depth of cut of 3mm.

Fillet may work with a setting of .06mm or smaller, but this wouldn't be very visible.

You could try using a pattern on path to create the negative of the rope (think of it as a female mold), then use combine cut to create the round rope.

One of these might work for the milling operations.

Thanks for the advice etfrench!

the link dosent work, I have a tapered carving bit that has a ball end of .5mm and then tapers up to 6mm with a cutting length of 24mm.

I can make the pocket recess deeper say too 8-9mm

Could you explain pattern on path and combine cut some please?

The bit I'm using

 Heres my cutter

Thanks

Sorry, I should have said Sweep instead of Pattern on Path

I just did the screencast to roughly show the technique.  You will need to make the path align better with the rope.  It will probably work better if you separate the different bends in the rope into separate components and create paths for each segment.

Thanks!

looks tricky but I'll give it a try 🙂
