From v 9.1.0b to 9.1.1b

What's new from version 9.1.0b to 9.1.1b 

Preprocess:
Import of x y z? ASCII files as points of nodes
Export template DXFSAP2000 updated
Two more variables to control the chordal error of the whole model when generating the mesh

Postprocess:
STL ascii and binary export of triangular and quadrilateral meshes. Only the displayed ones are exported
New Points/Circles/Spheres visualization mode: Internal texture. This option is a compromise between a nice view and a quick response time.
Display of axes, Matlab like, for the visualized model
Option to attach the progress bar, when a file is opened or written, in the main windows, avoiding unnecessary redraws
Visualization of scaled results, including the logarithm of the result: log( factor * ResultValue + Offset)
Logarithmic graphs
New option to improve the quality of the saved GIF images: Dither666 and Dither595, in the "Save GIF file box"
The new meshes created with transformations have the same color as the originals

Generic:
zoom centered on the current cursor when using mouse wheel
GIF: used dithering to convert the 24bit-colors to gif 256 colors' pallete.

News for problemtype developers:
Updated to Tcl/Tk 8.5.6
GiD_Info project subcommands RequireMeshSize and RecommendedMeshSize
GiD_Geometry can get and create more types of surfaces: plsurface, coonsurface and meshsurface
