iPocket Draw Lite vs Quickfem

** look at the video tutorials put online on our site ** iPocket Draw is a vector drawing program comprehensive (CAD 2D), which offers to you total control over your drawing. This Lite version includes a limitation on the number of objects (50) by drawing. Of course all the simple drawing tools are available: line, rectangle, oval, arc, polygon, text. But also tools of free line with vectorization option (recognition of simple shapes), spline, regular polygon. All attributes of each object can be edited and changed: line color, line thickness, background color, dotted, arrow, font ... But also the coordinates of each object because iPocket Draw lets you draw with a scale chosen and modified. iPocket Draw also has a cotation tool simple and multiple. And functions of attraction powerful and accurate on the ends of objects but also the centers and on the intersections between all object types. The drawing area is not limited. The number of objects either. The zoom in and out either. The number of undo either. You can draw on several layers and create configurations of layers. You have an object library that you can complete as you want. A comprehensive menu command allows you to: select all, copy, cut, paste, group, ungroup, lock, unlock, duplicate, move, mirror horizontally or vertically, rotate, align, distribute, create parallel, divide, change the scale, converting in lines, polygon, send back, put in front of. You can insert photos or images or pdf files in your drawings. iPocket Draw has a file manager from which you can send your drawings by e-mail format iPocket Draw (RealCADD) or DXF or pdf or jpg image. But also to export in a photo album. And also print. If you have problems, please contact us by mail (see information window of iPocket Draw: i button). Thanks.

Quickfem, the 2D Finite Element Analysis App for Engineers and Students. FEA for Students Learn how finite elements and structural analysis works by starting out with simple models you can build directly on your phone or tablet. Play around with geometry, constraints, loads, materials and results to augment the theory. FEA for Engineers FEA is hard. Most problems are 3d and complex and require the major packages such as Ansys, Abacus, Patran, Nastran etc. But engineers have to know what to expect from these models and this insight stems from the understanding of simple mechanisms and effects. With Quickfem, you have the most convenient FEA modeller imaginable in your back pocket! Simple touch geometry creation, automatic meshing, quick mesh refinement, simple constant strain elements, and near solution instant feedback creates the tight iteration loops necessary for rapid discovery. Running on your mobile device, Quickfem gives you the freedom to create and understand structural models wherever and whenever inspiration strikes. Know what to expect.
