What HN said

What people liked

  • Simple, smooth and easy to learn

    From 4 comments
    • 3DC enables anyone to start creating in just a few minutes. No previous professional 3D experience needed. It's designed like LEGO for the digital world. By combining the…

    • I can see myself using this for simple communication on 3D geometry work to my colleagues (I work a lot with 3D rendering). Hand drawing is so hard sometimes :). However, for…

    • This works sooo well on mobile, loving this!!!
      rutierut on HN
    • I've been a blender hobbyist for about a year now and it's a bit creepy how smooth this is on my iPhone at the moment. Thanks for sharing I hope I remember to dig more into this…

    • i like it. i like that it's offline (or atleast when my firewall blocks it, it still works)!! and i like that you dont need an account to use it. Mobile version is basic and…

  • Good CSG and push/pull features for a simple tool

    From 2 comments
    • Full CSG. Very nice. Clipping a cube with a sphere works.
      Animats on HN
    • 3D tools can often be overwhelming, especially if you only use them occasionally. The push/pull feature reminds me a bit of SketchUp, which I really like. Anyone have any…

Objections

  • Selection behaviour is confusing on desktop

    From 2 comments
    • Thanks for making this and sharing it on HN; I like the simplicity of it! The way that selection works really confused me, though. Here's what happened: I made two objects. I…
      panic on HN
    • I'm seeing the same behavior on mobile (surprised it worked so well on my ancient phone!). Make two items, tap the first item, then tap the second one. It still looks confusingly…

  • Lacks precise numeric input, keyboard shortcuts and advanced editing

    From 3 comments
    • - Camera rotation is way too slow for my tastes. - Tools should have keyboard shortcuts. - It's rather ambiguous, say, what the subtract tool subtracts from. - Scaling tool must…

    • The iOS app is a pleasure to use. I would love the ability to input numerical values via keyboard for things like dimensions, positions, rotations, etc. Another user mentioned…
      copperheart on HN
    • First, thank you! I use the ipad version. Some needed features: - precise editing - manual entry of dimensions - different materials and transparency - library of common items…

  • Rotation widget is nonstandard

    From 1 comment
    • Your rotation widget is nonstandard compared to most other 3D editors. See for example Blender[1] or Maya's[2] widgets (which are both basically the same). It's also kind of…

  • Too simplistic with no textures or transparency

    From 2 comments
    • What are use cases for this tool? It's too simplistic. No shapes other than (combined) primitives, no textures.

    • I would love to have some info on particular object size and ability to set sizes/rotations precisely, so I can do some simple modeling for 3d printing.
      achikin on HN
    • One feature I didn't see would be a way to specify a desired size. To be to type 50mm to get an object at that length would be helpful. Similar to when using the ruler in…

  • More login options besides Facebook

    From 2 comments
    • I don't use facebook. Mind offering other options to sign up or log in?
      it_learnses on HN
    • Love it! Would be nice to get the option to log-in without a facebook account. I don't have facebook, so I used it without logging in. Not sure which features I was missing.

  • Export to Three.js or JavaScript-based shape coding

    From 2 comments
    • The threejs.org/editor has some functionality for this. We will be adding Three.js export support soon as well, so hey, maybe combine the two.
      eerikkivistik on HN
    • I love it. Would really love the ability to "code" a shape using JavaScript.

Questions

  • Can it be used for 3D printing with precise sizes

    From 2 comments
    • I would love to have some info on particular object size and ability to set sizes/rotations precisely, so I can do some simple modeling for 3d printing.
      achikin on HN
    • Thank you for replying! The sub-mm scale would be to accurately model small things. When making a case for a raspi0, for example.

  • How to use the push/pull feature

    From 2 comments
    • How did you get the push pull aspect of things? I couldn't get that to work.

    • Great work so far! Lots of work to go if you're going to differentiate yourself from the leader (i.e. Tinkercad). Add tools that allow manipulation of edges and faces and you'll…
