Five Flute

Better design starts with better communication.

Five Flute helps your engineering team communicate more effectively so you can design great products together.


3D Design Review

2D Drawing Review

Catch design and manufacturing mistakes before they happen

Don’t wait until parts are manufactured to catch critical manufacturing problems. Five Flute superpowers your drawing review process so you can catch mistakes before release.

Great design doesn’t happen in a vacuum

Siloed design environments and legacy CAD tools make communication difficult.
card1PLM isn’t for daily collaboration.
card2Legacy CAD is not a multiplayer product.
card3EE is disconnected from ME.
card4Design is on an island.
Most teams use screenshots, slides, docs, email and chat as a workaround. This takes extra work, lacks context, is harder to track, and fails to capture your design history.

Build a unified design history

Five Flute gives teams a unified review environment so they can spend less time explaining issues and more time solving them together.

Transform your engineering communication

“Before Five Flute we would use screenshots and PowerPoint presentations to mark up 3D CAD. It was messy, hard to communicate concepts, and required meetings to go over.

Five Flute has transformed our 3D CAD communication process, replacing messy screenshots and PowerPoint presentations with an easy to use 3D system. We have found it extremely useful not only for conducting design reviews, but also all sorts of projects that I never even knew what I was missing it for. It's fantastic for marking up designs in 3D and doing asynchronous design reviews, but also it's great for when I am assembling parts for the first time. We can mark problems as they happen, as opposed to taking pictures and then trying to remember issues later. Such a useful tool!”

“Before Five Flute, we used an elaborate system of scanned paper redlines, in-person meetings, and Excel trackers to ensure that engineering could adequately respond to changes in manufacturing. Now with Five Flute, we are able to seamlessly collaborate across internal teams, manufacturers, and geographically distributed contractors to deliver our production drawings faster and more accurately than ever before.”
