Curious to see how this performs against fusion 360. Autocorrect has gotten real aggressive on pricing and licenses of late. Also fusion forces you to save to autocad’s cloud and they inspect your designs for hints you’re using it for non hobby stuff.

Another simple libre CAD program is SolveSpace. It works more like Autodesk Inventor - you draw 2D sketches, pull them into 3D in different ways, repeat, and add constraints to features along the way. Very good for the dimensionally-accurate stuff people model in Fusion360. (Nearly useless, I might add, for organic stuff like the mosquito in the Dust video.)

> Autocorrect has gotten real aggressive This sentence is meta on many levels! (He probably meant "Autodesk" but autocorrect kicked in rather aggressively, as he anticipated).

Haha. Yes.

Autodesk has a new office in Portland and I attended the Fusion 360 community meetup a few weeks back.

At that meeting they debuted their new pricing plans and demoed some pretty fancy functionality called generative design that was def not useful to the largely hobbiest attendees in the crowd.

It definitely feels like there is a niche of sub-fusion use case where you are doing simple commercial product design but not at a rate worth a $300 license from autocorrect

Does this use the same coordinate space[1] as Maya , or does it use the same coordinate space as Blender ? Blender has no end of hidden trouble importing to Unity because Unity chose to be the same as Maya [1] https://blender.stackexchange.com/questions/471/is-it-possib...

Dust3D use right-handed coordinate space, X - front view, Z - side view, Y - up. I am not quite sure what exactly coordinate space other software use, but I make sure the exported fbx looks as the same in Unity, and the exported glb looks as the same in Godot.

If the fbx loads into Unity fine, are you not using a left handed system, or are you flipping it on export?

edit - I'm an idiot, Unity does its own conversion to left handed on import.

Earlier quoted context omitted.

TIL. The fact that gaming and Maya use one (Y-up) and that CAD and Blender use another (Z-up) brings the classic xkcd to mind. https://xkcd.com/927/

The fact that there are only 2 makes me think that it doesn't apply though. I just hope nobody trise to go make a third.

There are more than two, Unreal has a coordinate system so special that Tim Sweeney apologized for it.

The "just have a reference photo" approach really appeals to me as someone who has never been great at sketching from scratch. I'm going to give this a go for creating custom assets for some little mixed reality projects.

If you have any more than zero experience modelling, Blender offers this and a great number of other tools for modelling, rigging, and animation.

Also, Blender is coming up on a big release which should make it a lot simpler for newcomers to get started. If you are willing to save often, you could just start with the 2.8 Beta now, and you won't have to do any adjusting when it comes out as stable.

Thanks for this. The 2d sketches to 3d is what I do with Fusion, and allows you to build nice 2d spec sheets as well. I will have a look.

Great concept! As a time-starved hobby game dev, the focus on being able to make something quickly from a reference image is really refreshing, in comparison with the more common design approach geared toward those with deep, well-practiced polygonal modeling skills. I like the direction your interface is going in. I love the Skin Modifier in Blender, but the workflow for that does feel a bit tedious, so I like the click-to-add-node approach. I also appreciate being able to move the rendered view around the window and scale it as desired.

Thank you from the bottom of my heart for making an alternative to one of the most unfortunately convoluted, beyond unusable pieces of UI/UX garbage on the planet...(Blender)...what a nightmare to use for even a moment.

Not sure if you’ve been following the 2.8 developments this year, but if you haven’t you should grab the latest beta. The new UI/UX is completely different from before (within reason) and is light years ahead of where it used to be.

I downloaded the beta for windows, clicked around a bit and it crashed. I noticed there doesn't seem to be any crash reporter. Is there somewhere I can report this bug?

Hi, some reported several hours ago, and I have released 1.0.0-beta.4 to fix it, could you help to verify if it still crash please? Download link for windows: https://github.com/huxingyi/dust3d/releases/download/1.0.0-b...

Seems to work ok on Windows 7. (My parents' machine, nonwithstanding my username ;)
