Inserting SVG hangs up issue

[Anonymous]

I am trying to import an SVG file . What I want is to extrude this SVG and finally engrave it in wood. I have attached the SVG file to this post.

So, each time I try to insert the SVG file in Fusion 360, the import process is working in an infinite loop even after one day and one night spent to let it inserting correctly without success.

Is there a way to achieve this import in F360?

Help will be appreciate.

I would strongly not recommend trying something this complex with Fusion.  Fusion is not in "an infinite loop", there are just tens of thousands of arcs and lines in this SVG, and this will overwhelm Fusion's sketcher.  Fusion's sketch environment is a constraint sketch environment, so every single one of those curves will have to be fed into the constraint solver.  My guess is that it will eventually finish, but the performance working with it from then on will not be pleasant.

Hi Jeff,

Thank you for your answer. Do you think this performance issue  is linked to the cloud architecture ?

I ask you this because I tried standalone product which is able to load a such SVG in just 10 seconds and extrude it in 5 seconds but I prefer by far the use of F360, which is really more intuitive.

If this is the case, do you know if a standalone version of F360 is on the roadmap?

Thanks.

No, the issue is the complexity as he said. You're giving a calculator a picture and wondering why it can't understand it.  Use something else to send it to the CNC.

@Anonymous , as @SilverHornet says, this has nothing to do with the cloud.  All the processing here is local.  A "standalone version" is not on the roadmap, and would not help in this case anyway.  The problem, again, is that Fusion's sketch environment expects hand-created sketch geometry for the purposes of building precise models of parts and assemblies.  Each line/arc in a sketch is solved against every other line/arc in the sketch, and this is an expensive operation.

Hi,

With Fusion I had to abort inserting the file after 15 minutes. From this I conclude that it does not work.
If you want to engrave, you don't necessarily need an extrusion.
I did it with V-Carve Pro.

This is the result:

If you tell me which system you are using, I may be able to find a suitable PP in my PP library for creating toolpaths.

Hi Jeff,

Thank you for your feedback, I understand what you said.

When I talked about the software roadmap, I try to introduce some kind of ideas.

what I tried to say is that It could be a great opportunity to get 2 different sub-modes of sketch/toolpath creation in Fusion. Indeed, First, several semi-pro software are able to achieve this kind of job easily whereas Fusion not. Second, I know a lot of people (me too) who will enjoy using Fusion - because it is more intuitive -  if this kind of functionality would be added. A lot of people like professional (not just students) able to pay it. As a Student in the CAD/CAM field, I will be a professional too in that field too.

You said that Fusion's sketch environment is a constraint sketch environment, so I imagine, in terms of software architecture, there is a kind of solver/manager of constraints by sketch, between sketches and related to. And I  understand this kind of resolver requires time-machine. With 2 different modes (constraints activated, constraints not activated), this issue could disappear. I understand that it is not simple but this is the concept. For instance when the constraints would not be activated then this kind of work would be possible in Fusion but for now, I understand this is not an available functionality but I am sharing with you my will as a user of Fusion.

I hope this kind of user sharing could have an interest.

Hi Guenther,

Wahoo! The result is great!

Thank you for your answer and the test you did in Fusion. I had another feedback from Jeff and I just tell him It could be a great functionality to get it in Fusion.

I really thank you for what you propose to me about the post processors. For now, I do not use any particular PP (I should do it. I directly edit GCODE as it is something I used to do in the 3D printing field). But the aim here is to learn how to do it myself. However, what you indicate me (about V-Carve Pro) is really helpful despite the fact I would prefer to use Fusion. The guy who has created the SVG uses products from Aspire but I am not comfortable with it - no ways to set mms in place of inches for instance -

I know I have to use software to achieve a CNC job. But as a future pro, each of these software has a cost and minimizing these ones will increase the benefits too.

Thank you again for your answer and for the time you spent to read those posts.

I will continue to learn with the advice you gave me.

Hi,

Just this much: If you mention Aspire, I assume it's Vectric's product, just like V-Carve Pro.
In both there is the possibility to work with both mm and inch.
Regarding the prospect of getting similar functionalities in Fusion, it has to be said that AD has discontinued its counterpart (Artcam) to Vectric 2018.
I can't imagine AD would allow modifying Fusion's Sketch Engine a way graphics to be edited (on reasonable terms). This may mean that essential functions (e.g. constraints) are restricted or disappear altogether.

The reaction of the user community would be incalculable.

Hi,

Yes, you are right, I talked about  Aspire Vectric. I knew how to set units for the workspace but I still do not find how to set mm for the tool definitions.

Oh yes, I understand that AD will not remove constraints or anything like that, I just think about adding a new condition to the Fusion's Sketch Engine and the condition would be something like: "use the constraints solver" or "do not use the constraint solver".

When the condition would be equals to "use the constraints solver" then nothing changes from the current behavior. When the condition would be equals to "do not use the constraint solver" then the SVG insert will not be processed by the constraints solver but the counterpart would be that only some functionalities in Fusion would be available (depending on how deep is the constraints solver in the whole CAM process)

This condition could be selected by the user (by using the correct wording of course). But as usual in software architecture, this is not so easy to do I guess.

Whatever, I agree with you I do not know if this kind of functionality could be on the roadmap and I do not know either if this will be possible on reasonable terms.

WRONG.  It's Fusion.  I have the same problem with complex vector files being uploaded to Fusion. The same file can upload in a couple seconds into Blender, while Fusion takes an hour.  Fusion's cloud-based processing is horrible.

Fusion is not cloud based. It only uses the cloud for file storage, rendering and some simulations. The reason it slow with complex sketches is because it has a geometric sketch solver that gets overloaded if you have more than a few hundred curves in a sketch. Other solid moderes I've used suffer with the same problem and comparing them to other programs with dumb sketches is a waste of time, they are completely different programs.

You sure about that?

Yes, the client version is installed on your computer, only what I stated above is using the cloud. There is a browser version that runs in whatever browser you are running, are you using that?
