This should not be taken as an exercise to create a viable fish lure design. I have greatly simplified the model that was sent to me by Bill to make it more demonstration friendly. Please consider this as more of an attempt to create a limited cross hatch pattern on a certain shape. There are many other design considerations to take care of when it comes to fish lure design.

Love your videos! For a case like this however, I propose it's way easier to sweep and twist a few lines to cut the outer face (like a multi-start thread) then also cut in the reverse direction for a natural easy diamond shape.

[@WMBayouLures]

Wow man you are a legend! Amazing work, thanks so much! I learned about 5 new things from this video alone.

[@angelomonopoliroca523]

cool video. I beta by non with all updates it can be done from other pointes of view. I Was thinking to start with a surface sweep of a line along the axis of the body as path. And adding a twist on its settings . Then thicken the surface and perform a circular pattern of the thicken. Repite the exact thing from the other side of the body (or copy and move 180 degrees) and then perform a Bolean cut. Main advantage is that you could cover the hola body with the pattern. I doupt the Emboss funsion could be thanks along 360 de body. I love your videos, helped me a lot to develop appropriate mindset. A good challenge that i believe could help a lot of engineers is making custom screw threads . (I struggled a lot with this for some time)

This is hugely helpful, thank you! I've been searching for days to find a solution to my problem and I finally found it here. I think that's worth a coffee ;)

[@SwissplWatches]

this is incredible! like watching magic being performed

Another of your videos saved to my Fusion360 playlist 👍

[@smorris12]

Another excellent video! Hope the algorithm approves!

[@ianpendlebury3704]

As usual, I learned a couple of new tricks/techniques here. Thanks.

[@_Kinger]

Thanks for this! I’m creating knurling on a complex surface and these methods should be much easier than making individual sweep cut profiles!

[@LearnEverythingAboutDesign]

Josh, one potential issue with that is the cut direction won't be normal to a complex surface but rather the surrogate. As long as you can make a surrogate close enough to your final shape it will certainly be quicker, but harder to get a true knurl knife edge.

[@ZenoErwt]

Thanks for another great lesson!!

[@a330turbinex7]

Superb!

[@kabi8867]

This is exactly what I need. Would like to make knife handles with my cnc and would not know how. If the bars were still slanted.... Thanks for the tips

[@zapod20]

I tried replicating this using a technique for generating knurling over surfaces with 2 degrees of curvature. Fusion would not compute the circular pattern of a sweep cut with a square profile (nor would it allow me to build a combined body with square profile bodies to use as a cutting tool). However a triangle profile did work for me (simpler geometry I guess) but the result gives a more knurled look than the hatching look.

[@gowrestle160]

I think it would be easier to create the limited pattern in this manor: split the body 2 times. once to cut the "head" off, an once to cut the body into top/bottom halves. Hide the head and bottom halves. create sketch on the front face of the top half, in this sketch draw one vertical line and 1 line 45 degrees to that vertical line. Both lines will be coincident with the top Arc, and the center of the bottom line. Repeat this process on the rear flat face, but make the angled line opposite of the angled line in the previous sketch (i.e. -45 degrees, so that if connected the line would cross the body). Finish sketch. Create new sketch on the top plane and project the coincident point of the angled lines where they meat the arcs in their respective sketches. draw a straight line or spline connecting those two points depending on wat shapes you want. Extrude as a thin feature, make sure that it is protruding through the original body all the way, and create a "new body", finish extrude. Circular pattern this extruded "fin" as many times as is desired around the central axis of length of the entire bait. join these fins to themselves, but not to the top body. Mirror these fins across the plane that bisects the top body into left and right sections. In my case it was the right plane. Then join the mirror to the original, do not join to the top body. Once you have this body created that is your cutting tool. Hide it temporarily, create a copy of your top body, use press pull to shrink the top face by 1 mm. Turn the cutting tool back on, use the copy of the top body to cut the cutting tool, then use the newly cut cutting tool to cut the original top body. Once it has been cut restore the hidden head and bottom body and join them all together.

This would be so much easier if emboss worked on double curvature surfaces. Is the fusion team ever going to change that or we stuck with this limitation for a while?

[@00991920]

Great tutorial. Question, whats the purpose of the boundary fill in the first method? Thanks.

[@mawoodmain]

I think the second workflow can be optimised, after the emboss you could create a copy of the original body, move the face in by the pattern depth desired then combine it with the patterned cone, once you have done this you can just combine the patterned cone with the original half model with the mode set to intersection, the excess on the body will be automatically removed by the intersection and the pattern will be removed from the original body as it is missing from this tool body Edit: Made a video of this process: kzbin.info/www/bejne/p2GndqyLeJd6npI

[@LearnEverythingAboutDesign]

I like it Matthew. There are probably 6 different ways to go about this and picking the "best" way is always a challenge. Replace face, offset face. Press Pull, Thicken etc could all be used. If you take a copy of the outside surface and Thicken it inward the distance of you cut, but use the "Intersect" option with your emboss solid body, you will make solid bodies that can be used for the cut without the extra work. In this case you will likely have a lot of solids but you can box select them. Another way is to Thicken the surface the distance of the cut then use boundary fill, but this makes you select a ton of cells(possibly) depending on how your bodies are laid out. One of those two is likely the most efficient option.

[@mawoodmain]

@@LearnEverythingAboutDesign yeah thats a good idea, once thing I did notice about every method that uses the emboss commands is that they cause fusion to freeze for several seconds :D I don't think emboss handles thousands of lines well. I'm not massivly familiar with boundary fill I tend to just work around it.

[@Cicada-uv5se]

Is there a way to make a potato chip shape extruding on the top of a rectangle?

[@drbra1n]

Isn't double thread and sweep better?

[@Fusion360School]

It does seem like a sweep with twist would work. This did not occur to me while making the video. I will definitely need to try this out. Thanks for the suggestion. Might do a follow up.

[@drbra1n]

@@Fusion360School Thanks for great videos, these are very useful :) I wasn't able to make an update with screenshot as youtube remove my comment. Double twisted sweeps works perfectly

[@LearnEverythingAboutDesign]

Awesome workflow as always! I was really curious how that first method would work out! If we had a true wrap tool or a surface unwrap this would be easier(without add-ins). I would probably go the route you went on your second example, but if the curvature varied a lot more than that lure(relative to your surrogate) another option would be a sweep cut. This would be the way to do this if it was a true knife edge knurl. Project curves onto the lure surface, planes on curve and pattern what you can. a360.co/3GvqFNx Unfortunately it requires ALOT more work this way with curvature in 2 directions because a pattern just wont "cut it".... Note that I didn't do the whole lure in my example but the point should be clear. There are other challenges like twist on the sweep. Other controls like sweep with guide surface could be used to control that but as a quick example I didn't want to dive too deep, but just like with your surrogate workflow its a good idea to have an extension of what you actually want to cut. With this design I would probably take the upper half surface and then extend the edges down for the sweep guides so the ends taper away from the solid body. I really enjoy these videos! Your approach is creative and often times wouldn't have been my goto. I like the thought you put into the approaches and the speed.
