Alternatives for Fusion

I have just experienced one too many bugs in the basic functionality of Fusion and I am looking for suggestions of alternative software packages with similar (but working) functionality.

I run a paid-for version of Fusion and will not be renewing my subscription when it comes up for renewal. I have experienced too many bugs in the basic functionality that might be acceptable for beta level software but should not creep up in seasoned software.

The functionality I require include parametric cad functionality, and cam functionality at the level that Fusion provides but without the severe bugs.

Freecad’s cam functionality seems rather primitive compared to Fusion so I am reluctant to go that route. (bonus because it runs under Linux)

Vectric does not, to my knowledge provide proper cad functionality and there is no parametric functionality at all.

Aspire costs WAY more than what a garage tinkerer can afford but I am willing to listen to arguments that could possibly convince me that the software is worth it’s cost.

What software do you use? Are you happy with it’s functionality? Is it reliable in the sense that a basic file search for old projects actually works (I have some major rants bottled up in me but I won’t subject the general public with the ridiculously screwed up functionality of Fusion)?

I have spent maybe 3 years with Fusion and am somewhat familiar with it’s work flow but I think I need to put some serious effort into finding a replacement.

Edit: 3D capability is required

You might want to keep an eye on the CAM3 builds for FreeCAD: Releases · tarman3/FreeCAD · GitHub

Because the CAM devs seem very active, I expect significant improvements to the relevant functionality over the course of the next few months. With luck, I’ll hop on that train in 2026 - maybe during the 1.2 release cycle.

Check out the FreeCAD Discord channel.

Anybody use Alibre? If so, what are your thoughts on it?

Plasticity is a low cost (179USD and 299USD) modeling program . I had started using it but the trial doesn’t import DXF so it was a no go for me. Only the 299USD version imports DXF. I don’t recall if it was a parametric modeling application

I did some digging and from what I have read, it does not seem to be parametric and it also seems to be geared to ‘modelling’ rather than CAD work.

What are the bugs you’re seeing?

Oh boy …. rant following (hey, you asked for the details):

About 6 or so months ago, my ‘recent data’ (not at the windoze box so I can’t confirm what it’s called) listing decided to loose the vast majority of it’s entries. Eventually it was decided that re-installing Fusion was the thing to do which broke a whole bunch of customizations and add-ons. That was my first encounter with a file system that is partially broken.

A couple of days ago I attempted to start working on an older design (Dec 24). I didn’t know the exact name and it wasn’t in my ‘recent data’ listing. I used the search function in Fusion to look for any files that include the word ‘Drawer’. I got a whole bunch of hits - way more than there should be. Most of these files could not be loaded. Tech support remoted into my computer to see what was going on but had no idea what was happening and it was decided to push the issue to level two support. I have a problem leaving good enough alone so I spent quite a bit of time trying to figure out what was happening. As it turned out, the search that fusion did when it was looking for the word ‘Drawer’ somehow included all my deleted files. They could not be loaded because the files no longer existed in the regular Fusion file system. The search results had been ‘poisoned’ with invalid data.

Fusion allows for web access to the file system and this access lets me see deleted files, restore them or erase them permanently. Every folder and every sub folder has it’s own ‘trash’ listing. Since the search result was poisoned by the files that were in the trash system, I had the bright idea to permanently delete SOME of these previously deleted files. I went to the main folder for all my projects and mass deleted everything in the ‘trash’ folder. Autodesk, in their infinite wisdom, decided that this obviously meant that I wanted to delete not just the relevant files in the chosen folder but also the content of ALL the trash files in ALL sub folders. This is a permanent delete that can not be undone!

While this fixed the issue of the poisoned search results, it precluded me assisting in any sort of further trouble shooting with tech support. The poisoning was a glitch that only affected the existing deleted files and any new deleted files no longer appeared in the search results.

Since the search function seemed to work again, I did another search for ‘drawer’ (notice lower case ‘D’) which got no results. I did another search using ‘Drawer’ (notice upper case ‘D’) as the key word and got two hits. Additional searches found the hits even when searching for ‘drawer’! Unfortunately a particular file that included the word ‘Drawer’ in it’s file name was NOT found. I had it loaded and in front of my face yet a Fusion search did not find it!

This is ok when you have a small library of files but when you hit 50 or 100 files you can no longer go through each file manually. If you can’t find the file via the search function you have as much as lost the file and the work that was required to generate the model.

A bit more searching on the internet found complaints about the totally useless search function at least 5 months back. In conversations with Autocad/Fusion, people complained of many many hours of wasted time because files could not be found. Some people went as far as to say that Fusion was unusable for them because of this issue. It was a BIG deal! Yet, after some 5 months (or more), Fusion has still not fixed a fundamental failure in their software!

I could understand if we are talking about a beta level piece of software from a hole-in-the-wall developer but it boggles the mind how a software package that was released in 2013 by a major player in the cad market could have a fundamental flaw like that unfixed for 5 or more months.

Fusion has monthly releases. Bugs are fixed and new features are added. A lot of the bugs are what I would call ‘esoteric’ but they get fixed. A bug that is fundamental to the entire package is not fixed???

I suppose they could be severely understaffed in their development team but they are building fancy new features while ignoring bugs that make the software unreliable and/or non usable! The priorities are screwed up.

There are more things I could list but the broken search functionality was the straw that broke the camel’s back.

Yes, I will likely still use Fusion because I am reasonably familiar with it but I am not shelling out $700 (or whatever) for a yearly license.

Anybody using the $48 USD version of Solidworks (3DEXPERIENCE SOLIDWORKS for Makers)?

Are there any limitations other than that the files can’t be opened in a fully licensed version of Solidworks and that you are limited in the commercial use?

How is the CAM portion? Can it take a model of a box, lay all the components onto a flat sheet of (virtual) stock so that the mill can cut them out? While full nesting features would be nice, I would be happy with a way to lay out the individual parts of a model so I can mill them.

Freecad might be a suitable alternative sometime in the future but I need something that works now.

The makers version of SolidWorks is a joke. It’s buggy, have to login and connect through 3dxperience, which is somehow even worse than the SolidWorks maker version. I tried it, as I used SolidWorks for my job for 15 years, but I can’t recommend it.

I keep going back and forth between onshape and fusion for CAD. I wish onshape had a built in CAM for the free version but it doesn’t. I’ve been using EstlCAM mostly, but still on the hunt for something better.

I hear good things about Carveco Maker. I’ll probably try that next. Or just suck it up and use Fusion

I had a quick look and from what I can tell this is not a CAD program. It seems to be something along similar lines as Vectric Pro. or Aspire. Let us know what you think when you check it out.

@Jens I hear you about their file manager. I don’t have that many files but trying to find an older file a few days ago was an exercise in frustration. I’d like to save my files locally using a folder structure that works for me. But I’m using the free version right now so I can’t complain.

While it pisses me off to an unbelievable degree, it would appear that there are no suitable alternatives for Fusion. Besides the fact that nothing I have tried ‘speaks’ to me, the feature set of Fusion is just way above everything else I have tried (in both CAD and CAM). Note that programs specifically geared to milling were excluded because while they might be able to do signs and carvings better, they lack the ability of a true CAD program to design things for my 3D printer (anybody use Vectric or Carveco to design a doohickey to be 3Dprinted?)

Solidworks and Solid Edge where not considered because of cost for the full set of tools. The maker edition of Solidworks had too many people bashing it and Solid Edge doesn’t have (to my knowledge) a maker edition. I do not qualify for an educational license.

I spent some more time fighting with FreeCAD but from what I was able to determine, it isn’t even close as far as CAD features compared to Fusion. Of course CAM is not even a contest.

There are some fine programs out there that specialize in surface modelling but they have limited abilities as far as regular mechanical objects is concerned. I must admit that I did not seriously look into any programs that appeared to be primarily geared for surface modelling.

Alibre looked interesting for a while but it neither speaks to me nor does it appear to have the feature set I am looking for.

I will be continuing with Fusion because while the file system has MAJOR issues, it is still the best (for me and my use requirements) as far as CAD and CAM is concerned. Who knows, maybe Autodesk will come to their senses and provide for a way to reliably search through older projects.

I have not yet made peace with the thought of having to upgrade to Windoze 11 in order to get support for Fusion next year. It is not an issue with available hardware but more a perceived problem where Microsoft is heading.

I am open to suggestions if anybody feels that I missed something in my search.

@Jens “(anybody use Vectric or Carveco to design a doohickey to be 3Dprinted?)”

I have sporadic access to an older version of Aspire. I have created some simple models, exported them as .stl files, brought them into Bambu Studio and printed them. Judging from your past criticisms of Aspire, I doubt that this will serve your purpose, but you asked. :grinning_face:

Correct, in the scenario I use Carveco it would be as the CAM software with onshape for CAD

I have been a Fusion (Hobby version) user for 8+ years but about 4 years back I started using Shapr3D for my CAD 3D design and a mix of Fusion and Vectric VCarve desktop for CAM. I pay a subscription for Shapr3D of around $275 and made a one off purchase of VCarve desktop, upgrading the version when I see something worth having. I do 95% of my 3D CAD work in Shapr3D. It has a wide range of export formats and the objects drop into both Fusion and Vcarve. It also has a .3mf export which drops straight into my 3D printer slicer. I have a large format GRBL controlled XYZA mill, a CO2 laser cutter/engraver and a Creality K1C 3D printer.

My main Shapr3D design platform is an iPad Pro 12.8 (M1) and Apple Pencil. There are MacOS and Windows variants (which came after the iPad version).

If the prospect of doing the majority of your 3D design work in one package, and your CAM in another (or two), I suggest you give Shapr3D a try. I love it and it also includes parametric modelling.
