Flat Pattern Bend

Calculator will calculate the necessary dimensions for the construction flat pattern segments lobsterback bend, elbow , tee piece, frustum cone and truncated pipe, truncated cone with an accessible vertex and triangulation method...

Calculation flat pattern used as a template for cutting the pipe, producing with wall thickness s = 0.

Additional comment: Needs to have a thickness parameter. OK for thin sheet metal, but will be off for industrial duct which has typical thickness of 3/16" or 1/4". Should also consider bend allowance with a K factor for metal type.

I love it...layed out sq. to rd. yesterday and it was perfecto mundo. I think it is definetly a timesaver and a good tool for the other guys not so good at layout

Very useful app for Insulators. Adds are not an issue at all if you are at the fab shop. One 5 second add per pattern you may build for somewhere from minutes to hours. Just remember to ad laps where it is needed and spaces for beads and crimps when building gores. Be creative with settings and you'll find it even more useful :))

Not too bad of an app. Very handy when in doubt.. I know all different metals do bend differently, so some are a little inaccurate. Plus, I would like to see that you could choose the thickness of the flights in the Spiral pattern section.

Do you like watching adverts? If the answer is yes, then this app is right up your street. The second you click on the relevant item you want to view your met with an advert. And this will happen everytime you view stuff in this app. If the ads were every now and then instead of coming first and everytime you click on anything within this app I would have rated it higher but sadly it's a good app gone bad.

Very easy to use it. This is very useful those are engaged with fertilizer company. There mitres and dummy support and branches as well using. By the help of this app even though it's free can make a miracles. Keep update. Only one improvement required. While exploring the dxf file onlt branch cutback layout is exporting not header hole layout. So make update to export header hole layout as well.

Pretty cool. Like metal layout I had to do as an apprentice, in a handy app form✔✔✔✔✔✔✔✔ Nice to have for little home projects. Way too time consuming to be doing at the shop...... but maybe if you made templates ...... everything it high tech these day, but it is fun to do stuff by hand & mind occasionally.

Well done; very practical. Only the "Y" with angular derivation is missing; where: D1> D2> = D3; D1 and D2 are axial and D3 is the angular derivation to the axial axis and the same direction as D2.

Been a Sheetmetal worker for 25years and this pattern development app is absolutely brilliant, saves lots of time if you have to make a transition piece yourself and can't get one laser cut in time. Easy 5 stars.

Single ad, less than 5 seconds, runs before you open each drawing. Not a problem. Very customisable patterns. Highly recommended. 10/10

Seems to work quite well . Would be nice if you could print directly from the app .

Excellent app, has alot of the layouts that many other layout apps have

I'm a complete novice at sheetmetal work but with a little patience and the help of this app, I was able to tackle a quite complex hopper project which turned out really good. Excellent App! Thank You!

Good am very happy with this app. Very usfull for growing engineering industries,

Too Many Ads! The latest update now pops up an ad EVERY TIME you open a different pattern layout! While I love how easy the program is to use, the amount of ads has me about ready to uninstall it!

This is by far the best app for laying out flat sheet metal parts i use it regularly for square to round duct work. Love the new tank tangent addition as well. Very handy! Thank you.

Great app, have been using for years and has saved me a lot of time when it comes to doing developments. Its also great for checking if your calculations are correct.

Fantastic app to quickly get finished result for bending elements. User interface is intuitive and effective

Segmented bend not available as it was show in the aap icon

KAL. S. Dec 9, 2019     

Useful application for practising engineers. Too many ads. Let the ads be spaced once in 5 calculations or else the PSG databook is a better choice. Would like to see a curved or bent pipe having outlets. It would. Also be nice to have the frustums with pipe outlets

Straight forward simple to use

Kle. S. Apr 18, 2019     

Fantastic app. I like that you can export the drawing as dxf file. So it is very easy to cut it on the plasma cutting machine

Ver helpful and time saving

Very very helpfull n easy to operate

Nice app beacous help in my work easy

Mic. A. Nov 24, 2019     

This is a quick and easy app for especially fabrication engineering. It can make good fun in the workshop cuttong and fabricating any connection with precise accuracy.

Great app if you're doing sheet metal work. Takes out a lot of the guess work in forming sheet metal parts

Fra. D. Sep 20, 2019     

Super useful app. With some colors it will be better. Identifying the angles and cuts. Thanks.

Haven't layed anything out yet and cut material but gut says it looks good. If so, its a dream come true.
