Fusion cutting straight through selected geometry when engraving

[michaelkelly7104]

So this has been an issue for a long time - Fusion is not detecting the geometry I have selected and is cutting straight through it. Can anyone advise if there is anyone on the Fusion team working on this? I can skirt around it by projecting the geometry sometimes, or changing the geometry itself, but this isn't productive. Is there a reason this happens?!

@michaelkelly7104 Don't use the move command it is an extra 2 actions every time it is used where if you use a joint it is one and will stay as one command to the end of time and you can move the part however you want again and again without adding more actions to fusion.

Gotcha, thanks Daniel!

[michaelkelly7104]

I don't mean to be a bother as I know it's only been a couple of weeks, but any word on this George? After some experimenting it seems to be an issue with the complexity of some of the shapes and the way Fusion's engrave function is reading them. Tweaking the DXF and removing points often fixes the issue, but if it works fine with contour etc I don't see why it shouldn't work fine with engrave. Anyway, hope everyone has a fantastic holiday period.

Cheers,

Mike

Any update on this guys? Still an issue I face every day...

[michaelkelly7104]

Ok guys, I'm seriously losing the plot here. I run a little hobby group showing people how to make these things for their own use. I encounter this so frequently now it's becoming incredibly troublesome. I'm not even annoyed that this isn't fixed yet, only that I can't seem to get an acknowledgement of an issue beyond the kind gentleman who said it had been forwarded for review. I have integrated Fusion into my workflow and am accustommed to it, however I have to seriously consider switching over to a package like VCarve because I have no idea when this may be fixed and cannot contact customer support about this since I have an education licence. I've posted twice in the product update articles and have been entirely ignored. I'm not impressed. If I were considering purchasing a licence to be able to make these for profit, that's out of the window.

What do I have to do to get noticed? Push this on a Youtuber and get them to expose this issue that's been present for years now?

It isn't nice being ignored.

Could you share any other files that I can include to the ticket that was opened in December? The ticket does exist, but it does not appear to have risen to priority, too many other fires to put out it seems. Anything further you could share would be great, as it would give us more data points...

[michaelkelly7104]

Hi Seth, I appreciate your reply. I will compile some files I've had issues with for you.

Cheers,

Mike

[michaelkelly7104]

Here is one example, I'll attach more when I get the chance. Thanks again.

@michaelkelly7104  To me for the attached part using traces would be better than trying to use a V carve toolpath or selecting the top of the letters and overriding the set depth, is this for a branding iron?

[michaelkelly7104]

Hi Daniel, I'm happy with my process. I've experimented a lot with different toolpaths and engrave gives me the best results. Cheers, Mike

[michaelkelly7104]

Daniel, here is the result once I messed around a bit with the file and selections in Fusion. Fusion is VERY capable, there is no point skirting around this issue when it is such a capable software package. PS, for a branding iron you want the none contact areas as far away from the wood/branding surface as possible. If the none contact areas are too close then it will fade the design with the heat transfer. I don't know about trace, but it's important to have the variable Z height to maximise the depth where necessary, otherwise you'd need to use progressively smaller endmills to pocket these sections and it'd take forever. If you had to use progressively shallower depths of trace, it'd also take a while.

[seth.madore]

The issue, I think, is that you're selecting the Sketch itself, and not the actual characters. Now, Fusion gets sluggish the more contours you select, but we muddle through it. Selecting the base of each letter gives me this result:

Do you have any exampples where you HAVE selected each letter and gouged them?

 

[michaelkelly7104]

Hi Seth, yeah I have some which I'll post up here when I get the chance. In this instance, this is how I fixed this, but frequently it also fails when selecting geometry directly. As you can imagine, selecting every contour manually in a complex design is quite laborsome. I'm not a software engineer so don't understand the complexities of this, but if selecting the sketch works for contour and adaptive paths (it's never failed me for these toolpaths), then why would this fail for engrave? This is a bug, no? I don't understand why we're trying to skirt around this!

Thanks,

Mike

[seth.madore]

It's not that we're trying to skirt around anything. I'm trying to provide you with some workarounds, because I suspect where "Engrave bugs" are going to land on the long list of existing bugs.

Should it work as expected with a sketch selection? YES! Does it? No.. Will it get fixed? Hopefully at some point?

[michaelkelly7104]

Seth, I appreciate your help! I'm just frustrated with an issue that's been present for years and has been reported by others, where they've been given temporary workarounds time and time again for this issue to still be present. Fusion is so capable when it works, and this would seem to me to be a primary feature of Fusion (in my experience the work produced from Fusion is better than what I get out of the competition). For a primary feature that I utilise so often to be so broken for so long... well you get the idea. I'm just frustrated.

I will post the files when I get the chance.

Thanks again,

Mike

@michaelkelly7104 I have always found if you select the top of the letters it always works fine and that can be the sketch at the top of the letters or modeled part the modeled letters can be selected from the bottom as well just not a sketch at the bottom of the letters, the engrave toolpath is only 2.5D so it does not really know what is there V carve pro is the same, is it a bug maybe it could be a limation as well as selecting the profile can work and the sketch at the same place can fail.

[michaelkelly7104]

Yeah for sure selecting the geometry can help, but it's a nightmare with the complicated ones so I try and use the sketch profile as much as possible. I do have a file I've found where even this didn't work so I'll upload when I get the chance, I can put a few together too.

[michaelkelly7104]

Hello Autodesk team, please find attached some more evidence of the issue. The one with text I selected all the contours manually but engrave still ignores this geometry. For the other one it would have been impractical to select the geometry manually so I selected the sketch. Engrave is not recognising some of the geometry there. There are countless more examples and I'd find them if I dug through, but what I think it boils down to is engrave not liking points that are in close proximity to each other. If 2 points are very close together, then this seems to be a recipe for disaster. I would really appreciate a quick fix on this. I don't seem to be getting anywhere posting on the update logs.

[michaelkelly7104]

Is there an email address I can send any info to? I'm getting a bit tired of this!

[seth.madore]

I've opened up CAM-28620 to investigate Engrave issues. I will try to update this thread when there is more info to share
