## Why people recommend it

- Intuitive, approachable interface (6 comments): "I've found it very intuitive, though I'm not sure how ergonomic it would be for complex assemblies." ([source](https://news.ycombinator.com/item?id=47496513)) "It's pretty easy to use and feels intuitive for prints you'll only have to make once or twice." ([source](https://news.ycombinator.com/item?id=46340799)) "I am really interested in an Open Source CAD application with good UX, this one looks great." ([source](https://news.ycombinator.com/item?id=47500078))
- Good tutorial and documentation (4 comments): "the only traditional 3D CAD program I've ever tried where I actually made it through the tutorial without a showstopper" ([source](https://news.ycombinator.com/item?id=46035054)) "I managed to make it through the tutorial for Dune 3D twice now (after a fashion)" ([source](https://news.ycombinator.com/item?id=47086759)) "it is quite workable, and has quite good documentation" ([source](https://news.ycombinator.com/item?id=50275829))
- Robust kernel with fillets (4 comments): "combining the constraint solver from SolveSpace with a OpenCASCADE geometry kernel supporting fillets and chamfers" ([source](https://news.ycombinator.com/item?id=47084810)) "If you want a solvespace with chamfers and fillets, then give Dune 3D a try." ([source](https://news.ycombinator.com/item?id=47091319)) "Lately I have been using Dune 3D which uses much more reliable kernel." ([source](https://news.ycombinator.com/item?id=47231707))
- Simple for basic tasks (3 comments): "It's pretty easy to use and feels intuitive for prints you'll only have to make once or twice." ([source](https://news.ycombinator.com/item?id=46340799)) "I enjoy having simple solutions that get simple things done." ([source](https://news.ycombinator.com/item?id=47496535)) "pretty capable and simple for basic usecases" ([source](https://news.ycombinator.com/item?id=47501219))

## What people warn about

- Clumsy, frustrating selection and interface (3 comments): "selection isn't broken, but it's definitely sometimes frustrating" ([source](https://news.ycombinator.com/item?id=47499449)) "Dune3D is interesting but frustrating still" ([source](https://news.ycombinator.com/item?id=46032325)) "its interface is clumsy even if the 3D constraints thing is interesting" ([source](https://news.ycombinator.com/item?id=46345700))
- Limited features, missing SVG import (2 comments): "importing an svg, which it didn't support at the time" ([source](https://news.ycombinator.com/item?id=45977767)) "seemed quite promising, but very limited" ([source](https://news.ycombinator.com/item?id=46344709))
