Hestus: what owners actually say
Hestus's Fusion 360 sketch helper draws interest but frustrates users with installation woes and version-breakage, while veteran CAD engineers question whether it solves a real problem.
What owners complain about
- Breaks on Fusion updates COMMON
Multiple users report API errors after Fusion updates, with messages stating the 'sketch_helper' add-in from Hestus, Inc. cannot be loaded and requires a new compatible version.
- Difficult to fully uninstall SOME
Users report Fusion copies the add-in to a different directory, requiring manual deletion. One user says it got 'stuck in my system' and they couldn't remove it cleanly, requesting a proper Windows Installer-based uninstaller.
- Not on Autodesk App Store SOME
Users explicitly ask Hestus to publish on the Autodesk App Store for easier discovery and installation, implying the current distribution method is a friction point.
- Experienced engineers see it as a non-problem SOME
Veteran CAD users with 7–30+ years of experience say sketching and auto-constraints are already second nature and not a real time sink. One 7-year Fusion user says the tasks shown in Hestus's demo are 'the least of my problems.'
- Only works with Fusion 360 FEW
Users on Product Hunt and elsewhere ask whether Hestus will support other CAD tools, indicating Fusion-only support is a limitation for those on Solidworks, Onshape, or Creo.
What owners love
- Concept is genuinely appealing
Even skeptical veteran engineers acknowledge the tool 'sure looks cool' and that improving auto-constraint systems with AI and larger training data is a worthwhile direction.
- Addresses a real frustration for less experienced users
Users note that existing auto-constraint and snapping systems in CAD tools are often frustrating, especially when fixes cascade into bigger problems — suggesting Hestus targets a genuine pain point for non-experts.
- Fills a gap in real-time design feedback
Users express interest in the broader vision of tools that estimate cost or feasibility during design, referencing similar plugins for Solidworks — suggesting Hestus's approach resonates with a desire for smarter CAD assistants.
Surprising patterns
- The most vocal skepticism comes from deeply experienced engineers who have literally built sketch solvers (one implemented Solidworks Autodimension at D-Cubed in the 1990s), not from casual users — meaning Hestus's toughest critics are the people most qualified to judge it.
- A user raised concerns about whether Autodesk's EULA prohibits open-source add-ins, which could complicate Hestus's distribution model if it relies on open-source components.
- Users want Hestus to go far beyond auto-constraints — one specifically asked for natural-language input like 'I want to make a bracket with these mounting holes,' indicating the market expects more AI-driven design intent parsing.
WHO SHOULD SKIP IT
Engineers with years of parametric CAD experience who already find sketching second nature — multiple veterans say the problems Hestus targets simply aren't their bottleneck.
