Hestus
AI autocomplete that lives inside Fusion 360, predicting design intent and proposing sketch constraints and dimensions as one-keystroke suggestions.
Summary rewritten from the vendor site because the catalog version did not match it.
What it does and how it connects
Hestus is an autocomplete plugin for CAD that reads the sketch as it is drawn and offers the next move as a suggestion accepted with one keypress. The homepage example shows two centerlines offered for a fresh rectangle, placed as construction lines with one key, and a mirror suggestion that produces four circles with symmetry constraints included.
Suggestions can be cycled through until the intended one appears, or ignored by continuing to draw. The plugin covers constraints, dimensions, symmetry, tangency, and mirroring, and the homepage states it lives inside the CAD already in use, with nothing new to learn, nothing to export, and no part files to juggle.
The vendor states the tool is used by 5,000 engineers and that sketching runs 2.5 times faster with 4 times fewer clicks. The homepage shows no prices and no named CAD tools in its text; the Autodesk App Store lists Sketch Helper for Fusion, available in Sketch Mode with suggestions through a palette or keyboard shortcuts.

Recurring errors it addresses
Error Index entries this tool is built to reduce or work around.
- Cloud-first file model makes local file control, rename/move/backup workflows feel alien and risky.Error Index
- General UI/UX is described as confusing and hostile for routine work.Error Index
- STEP carries geometry only and sketch DXF only 2D profiles, so moving a Fusion design to another parametric CAD tool loses its intent. The proposal is a JSON export of user parameters, the feature timeline, sketch constraints and component transforms, with the STEP kept as the reference to check the rebuild against by volume and bounding box.Error Index
