Atlas computes the resulting moments and reaction forces for a given beam with loads applied to it (single as well as distributed), using Cross method.

A typical application would be to optimize joint positions (i.e. positions with zero moment) in purlins or beams.

Features:

• For 3D data in DXF format, you may manipulate (e.g. rotate, move or zoom) the 3D objects, and create a stereogram with the 3D objects in the particular position that you see on your screen. You may choose optional perspective for creating stereograms with better visual effect.
• For 3D data in range picture format, you may apply any linear or nonlinear function to map pixel values to actual distances. The built-in function parser accepts any function typed in C-style. It recognizes 13 operators, 44 function names, 2 constants plus unlimited number of independent variables. Please click here for a complete list.
• You may drag-and-drop to open any supported file. The program remembers recently opened files.
• The displays are fully interactive. They can be zoomed, moved, or rotated (for 3-D data only).
• The displays can be copied, saved or printed. For 3D plots, you may choose to copy or save them as bitmap, enhanced metafile, or data points in text format. The enhanced metafile format guarantees no loss of resolution when zoomed or printed.
• Four different types of 3-D plots are available: wire frame, color-coded wire frame with hidden line removal, color-filled facets, and shaded facets.
• 3-D plots may have optional perspective.
• You may change program settings including interocular distance, desired viewing distance, coding pattern scaling factor, stereogram size, resolution of display media, background distance, etc. And the settings are remembered when the program starts next time.
• Stereogram Maker automatically detects the resolution of your screen and printer. To create a stereogram hardcopy, it is recommended to print the stereogram directly from Stereogram Maker. The desired 3D effect might be lost if you use other software that changes the physical size of a stereogram.
• The program remembers the window position/size of the previous run.

JFDraw is a pure Java based graphics application and library package. JFDraw used a little features of Java2D, and expanded a lot of graph routines for more complex vector graph processing. You can run JFDraw under any operating systems that suport Java.

JFDraw is focused on vector graph drawing field. It can help you to complete your mechanical, electronic, architectural graphs drawing applications, or even business process or workflow graphs issues.

Written by pure text based editor(Windows NotePad & Unix VI), built by Sun Java Development Kit(JDK) 1.3.x and Apache Ant, JFDraw will offer you the opportunities to incorporate it into your graph applications, in binary library mode or source code mode.

Main Features:

• a variety build-in vector graphs, e.g. rectangle, triangle, parallelogram, trapezoid,polyline, regularline(continuous vertical or horizontal line), etc.
• automatic nodes combining or expanding in polylines and regularlines, its needless to add or remove a node for drawing such poly lines.
• easy to use adding/removing/binding/unbinding ports functions, for help doing ports issues(ports are used to connect shapes by lines) on arbitrary shapes.
• a lot of arrow types, fill styles and line styles, so you can easily change your shapes appearance to fit your demand.
• goup/ungroups, multi-layers, customized libraries and templates support.
• roate, flip, mirror and scale functions on any shapes.
• zoom in/zoom out or customized zoom scale, undo/redo with arbitrary undo depth.
• grid, ruler support with both english or metric measurement.
• binary/xml JFDraw build-in file format, export to jpg, png, svg and more file formats.
