CASA Space Frame 3D vs Superlist

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. * Members can be oriented to a third node. * Gravity (self-weight) loading. * Factored load-case combinations. * Rubber-band box for large-area selection. === General Technical Features === * Automatic analysis. * Integrated extensive section library: - British, European, American, Canadian, Australian, South African, Japanese, Russian. - See our website for the range of shapes. * Integrated section generator for common shapes: - Open: I/H, channel, zed, angle, tee. - Hollow: Oval, Rectangular. - Solid: Oval, Rectangular. - Calculates: Area, Inertia, Torsional constant, Elastic moduli, mass. * Integrated material library: - Steel, Aluminium, Concrete, Timber, Glass. - User materials can be added. * Member ends can be rigid or pinned. * Loads applied as point, couple, trapezoid. * 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. * Dynamic results include:   - Resonant frequencies   - Undamped oscillation mode shapes * Footfall results include: - Response factors. - Critical frequencies. - Both impulse and resonant responses. === General User Interface Features === * Universal App - for iPhone, iPod touch, and iPad. * Metric & imperial units. * Four simple interactive screens: - Geometry, Loading, Results: for interacting with the model. - Utilities: Supplementary functions (see below). * Easy modelling: - Tap to select; tap to edit. - Move and copy geometry. - Slide nodes along members. - Change member spans. - Split members. - Replicate loading across members. * Graphical drag-and-tap controls: - Rotate, pan, zoom the view with simple gestures. - Drag nodes for positions. - Drag loads for positions and magnitudes. - Drag marker along member to read off results values. - Tap on Points of Interest for important results.  - Select nodes to measure distances, angles, and areas between them. * Numeric entry available: - Double-tap on a datum to enter its numerical value. - 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. - Choice of unit system (UK/EU Metric, US Imperial). - On-line help. - Load, save, and export models.

From the team that created Wunderlist: Superlist is the to-do list, notes, and AI meeting app that keeps your work and life organized — and turns every meeting into action items automatically, so nothing slips through the cracks. Capture AI meeting notes, create tasks by voice, collaborate in real-time, and manage it all in one beautiful place. AI that turns meetings into action: - Auto-generate structured meeting notes — summaries, action items, and due dates — the moment your call ends. - Ask AI Chat follow-up questions about any meeting, or generate replies and next steps from your notes. - Speak your thoughts with the Voice Assistant — Superlist turns them into tasks, reminders, and notes instantly. - Convert Slack messages, emails, and Linear tickets into tasks with one tap. The fastest way from idea to done: - Create tasks in plain language — type "call Sarah tomorrow at 3pm" and Superlist handles the rest. - Start projects instantly with AI-assisted list generation. - Add due dates just by typing them — no menus. - Capture notes, brainstorm, and turn thoughts into todos. Everything in one place: - Organized, customizable lists with infinite subtask nesting. - Work projects, personal goals, and everything between — in one view. - Reminders and notifications across all your devices. - Repeatable tasks to build your routine. Work better together: - Real-time collaboration on shared lists and projects. - Chat inside tasks to keep conversations on-point. - Share lists, assign tasks, and manage work — without switching apps. - Integrates with Slack, Linear, GitHub, Gmail, Google Calendar, and more. Built for real people: - A beautiful interface that's a joy to use. - Customize lists with cover images and emojis. - Works on every device, online and offline. Why people switch from other to-do apps: Most productivity apps are either too basic or too complicated. The team behind Wunderlist built Superlist to give you the power of a task manager and project planner with the simplicity of a to-do list. - No complicated setup - Start free, upgrade when you need more - Privacy-first and secure. Made in Germany. Perfect for: - Daily to-do lists and personal task management - Team tasks and collaboration - Meeting notes and AI note-taking - Project planning and project management - Shopping lists, family lists, and checklists - Habit tracking, routines, and daily planning - GTD (Getting Things Done) workflow - Students, freelancers, and busy professionals Get started today for free.
