Hi Product Hunt! π Iβm Matas, the solo dev behind Zuflow.
This started when a mechanical engineer friend was venting to me about how frustrating CAD assembly tools are. He explained that most of the time, you just want to line up simple things like holes or flat surfaces, but instead, you get stuck fighting with opaque mates and hidden constraints.
As a software developer, it seemed crazy that such a common process was so clunky. I realized a visual, node-based system would make way more sense.
So, I built Zuflow. Itβs a web-based constraint solver where you:
Drop in loose STEP files.
Wire up the relationships on a visual canvas.
Watch the engine automatically snap the parts into place.
Export dimensioned engineering drawings and PDFs in a single click.
Iβd love for you to try it out with some parts and roast the workflow. Does a visual node approach actually make things faster for your daily work?
Let me know what you think in the comments! Iβll be here all day answering questions and fixing bugs. π οΈ
