## What is CASA Space Frame 3D?

Structural / Civil Engineering App for static & dynamic elastic analysis of general 3D space-frames.

With CASA SF-3D an engineer can create 3D structural models of space-frames and obtain both the numerical results and graphical representation of the deflections, forces, natural frequencies, and mode shapes. 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.


=== This App includes the following features:

* Linear static analysis.

* P-Delta non-linear static analysis.

* Natural mode dynamic analysis.

* Footfall dynamic analysis.

* Sway-cases.

* Geometry groups:
 - Include or exclude geometry from the analysis.
 - Groups can be combined into supergroups.

* Multi-copying for rapid generation of regular geometry.

* Rotation and reflection of geometry.

* Solid rendering of geometry:
 - Member cross-sections drawn to scale.
 - Colour-coded by groups.

* Viewpoint memories:
 - Store and recall for quick navigation.

* Multiple load-cases.

* Statics results include:
 - Reactions, deflections, bending moments, shear forces, bending stress.
 - Points of interest.
 - Results given all along members.

* Dynamic analysis considers self weight plus additional mass-cases.

 - Includes a convenient built-in calculator.

* Straightforward section library:
 - Pick from country, shape, and size.
 - View diagram and properties.
 - For custom shapes, double-tap on dimensions to edit.
 - Axes can be rotated by 90 degrees.

* Report generation:
 - Configurable content.
 - Graphical layout.
 - On-screen preview.
 - Export PDF by e-mail.
 - AirPrint.
 - CSV export of numerical data.

* Supplementary functions:
 - Document titles.

### 5/5 — It simply works

*2016-03-30*

The best mobile frame analysis tool available for IOS. Works ... stable and predictable 10/10!

### 5/5 — Great

*2013-03-07*

The software is excellent for analysis, I know in the future they include more command like copy all node or elements at same time in one direction and include a shell module for shearwall or slabs. Can be amazing include a design modules in the future.

Try it!👍

### 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)

### 24.01 — 2024-01-30

Maintenance update.
The app 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.

### 20.09 — 2020-09-13

* Corrected colours in Dark Mode.

### 20.06 — 2020-06-17

* Fixes bug whereby CSV/PDF button disappears in report preview in iOS 13.

* Fixes bug that limited access to iCloud files.

### 19.10 — 2019-11-06

* Now uses the standard iOS document browser. This makes import/export easier and allows documents to be arranged in folders.

* Due to the significant changes in file handling, we recommend that you back up your documents before updating (e.g. via e-mail or iTunes).

### 18.05 — 2018-05-24

Added the option to select members that are of similar section and material to the master selected member.
