## What is CASA Plane Frame 2D?

Structural / Civil Engineering App for static elastic analysis of 2D plane-frames.

With CASA PF-2D an engineer can create 2D structural models of plane-frames and obtain both the numerical results and graphical representation of the deflections and forces. There is an emphasis on quick and precise modelling with graphical interaction. Results are graphically interactive with a sliding readout of numerical results at any point along a member.

More information about this App can be found in its integrated help and on our website. The App also contains "Replay Demonstrations" which describe and enact its use.

### 5/5 — Good app

*2024-07-03*

Must do the tutorials first. Then it’s straight forward to use. Great little package.

### 5/5 — Good app

*2020-06-18, version 18.03*

I teach structural analysis and design.
This app is very nice.
You should have no problems if you follow the instructions.
My only complain is that sometimes is difficult to write the loads, but this only happens in my iphone, no problems what so ever in the ipad.

### 4/5 — Good

*2011-03-10*

This is a really good app, after reading the instruction it is easy to use. Short comings hence not 5 star are lack of automatic self weight loading and screen display of pdf output. Had to email myself to view.

### 5/5 — Brilliant for the Structural Engineer

*2010-05-22*

I have been waiting for an app like this for a long time, it's the quickest most accurate tool for structural engineers to do calculations any where anytime without having access to their computers. Even in the office it is sometimes easier to use this than a computer with more time consuming software. CASA's other apps are brilliant too.
Definitely the best structural engineering apps available, and I've tried them all.

## Version history (last 5 releases)

### 21.05 — 2021-06-01

Maintenance update.
The app now uses the standard iOS file browser, and we recommend saving any current documents and closing the app prior to updating. On first launch, if it opens in the "Recents" files tab, then browse to "On my iPad" and then to this app's documents. If the app were not fully closed prior to updating then the documents folder may appear empty when first opened, in which case close the app in the iOS home page and relaunch it.

### 18.03 — 2018-04-09

This app has been updated by Apple to display the Apple Watch app icon.

Improved compatibility with iOS 11 and iPhone X.

### 1.87 — 2017-03-06

Fixed indication of ambiguous major axis alignment.

### 1.86 — 2017-01-04
