It's a split decision.
Choose Autodesk Inventor for mechanical engineering: its toolset covers parametric and direct modeling, sheet metal, piping, simulation, drawings and CAD interoperability. Choose Sketch for macOS-based UI design, prototyping and developer handoff. They are not like-for-like tools. Inventor starts at $215.42 per user monthly on an annual term ($320 month-to-month); Sketch starts at $12 per Editor monthly, billed yearly. Both list 30-day trials; eligible students and educators can get Inventor free.

02Pricing compared
Autodesk Inventor costs $320 per user per month on monthly billing, or $215.42 per user per month when billed annually. The listed Inventor Professional license includes one named user, installation on up to three computers, and one active user at a time. A 30-day trial is listed; eligible students and educators can use the Education Plan free.
Sketch Standard is $12 per Editor per month, billed yearly; its monthly-billing price is not published. It includes unlimited documents and free Viewers, one Workspace, and 50GB storage per Editor. Professional is $24 and Enterprise $44 per Editor per month, billed yearly. Sketch also lists a $120 one-time Mac-only license, with one year of updates but no collaboration or free trial. These prices cover tools for different jobs, so the lower starting price does not make Sketch a substitute for Inventor.
03Features and depth
Inventor is built for mechanical engineering work. Its listed capabilities include parametric solids, direct face editing, T-spline surfacing and iLogic automation, plus dedicated tools for sheet metal, structural frames, mold bases, tubing, piping, and cable and harness runs. It also includes finite element stress analysis, dynamic simulation, weight-focused Shape Generator, automated drawings and bills of materials, and 3D geometric dimensioning and tolerancing. AnyCAD links to formats including STEP, CATIA, SolidWorks and PTC Creo without translation.
Sketch targets UI design, not mechanical product engineering. Its native macOS app provides vector design, stack layouts, frames, component libraries, and interactive prototypes with animations and gestures. Designers can work offline, co-edit and share work, while developers can inspect files, download assets, and export tokens for free. That is a focused UI workflow; the published feature lists do not show Sketch offering Inventor’s engineering, simulation or manufacturing-documentation toolset.
04Ease of use and learning curve
The two products ask users to learn different kinds of work. Inventor’s broad engineering toolset—covering modeling, simulation, specialized mechanical workflows and production documentation—makes it the more involved choice for someone who only needs to design screens. Its review scores rate ease of use at 6/10.
Sketch is more narrowly focused on UI design, with vector tools, layouts, prototypes and developer handoff. Its review scores rate ease of use at 8/10. That score does not mean it is a fit for mechanical engineering: its listed features address interface design. Choose based on the work your team needs to produce, not just the ease-of-use ratings.
Questions people ask
Which should I choose for UI design: Inventor or Sketch?
Choose Sketch for UI design, interactive prototypes and developer handoff. Its listed features include vector editing, layouts, libraries and offline work in a native macOS app. Inventor’s feature set is aimed at mechanical design, simulation and production documentation.
Can Sketch replace Autodesk Inventor?
Not for the mechanical engineering work described here. Inventor lists tools for sheet metal, piping, simulation, drawings and CAD interoperability. Sketch lists vector UI design, prototyping and developer handoff. They are not like-for-like products.
Does Inventor work with SolidWorks files?
Autodesk’s published product information says Inventor’s AnyCAD links to formats including SolidWorks without translation. The published information does not specify which SolidWorks file versions are supported, so check Autodesk’s current compatibility documentation before planning a migration.
How much does Sketch cost compared with Inventor?
Sketch Standard is $12 per Editor per month when billed yearly; its monthly price is not published. Inventor Professional is $215.42 per user per month billed annually, or $320 with monthly billing. Sketch also lists a $120 one-time Mac-only license.
