Text reports can now be configured and saved for later recall or included in a multiple report.
The plate meshing engine has been updated so that the meshing tools now generate meshes that contain more well-conditioned quads rather than triangles. This results in less elements and a better conditioned model in general.
Added plate cuts that you can draw anywhere across a panel modelled with plate elements to define a cross section through the panel. You can then obtain the forces and moments summed over the cross section.

Added a "Load contiguous members" tool that allows you to select multiple members that are connected end-to-end and then load them as if they were just one member.
Added a "Varying member distributed loads" tool that allows you to select multiple members and then apply distributed forces that vary linearly or are based on an equation that you can define.
A "Find" facility has been added to datasheets for searching for specific text anywhere within a datasheet.
Enveloped diagrams of "Absolute maximums" now retain the sign of the maximums rather than setting them all to positive.
Recent jobs are now in a "Recent jobs" sub-menu of the File menu which includes a thumbnail image of each recent job and some brief information about it. Up to 50 recent jobs can now be displayed.

Added a new bearing pressure plate contour type for raft footings.
Can now specify a filter in the steel member design modules to limit the members being designed/checked.

Bolted end plate and welded moment connections can now have doubler plates together with top and bottom web stiffeners instead of just allowing one or the other.
For bolted end plate and welded moment connections the user can now set the minimum design action as a percentage of ϕMs rather than being hardwired to 50% of ϕMs.

This is a major new version containing a significant number of enhancements and new features. SPACE GASS now also supports hardware acceleration in all modern graphics cards. Previously this was restricted to some NVIDIA graphics cards. For more information on this and how to optimize SPACE GASS for maximum performance refer to www.spacegass.com/hardware.

This is a semi-major upgrade that includes many changes, enhancements and fixes. It is also the first version that has all of the tools of the traditional SPACE GASS window now available in the renderer (along with many new tools that are only available in the renderer).
A new reinforced concrete beam design module has been added.
Tools for querying and viewing steel member design results have been added to the renderer. You can also label the steel member number, load factor and governing load case on each steel member in the model.
A load case title column has been added to the combination load cases datasheet.
Seismic checks in accordance with chapter 12 of NZS3404 have been added to the steel member design module. The clauses checked are table 12.4(1), table 12.4(3), 220.127.116.11, 12.5.2, 18.104.22.168, table 12.5, 22.214.171.124, 126.96.36.199(a), 188.8.131.52(b), 184.108.40.206(c) and 220.127.116.11.
This is a major upgrade containing many new features and substantial performance improvements, especially in the analysis solvers and graphics engine. It also makes the renderer the main interface for the program.
Introduced a new "Paradise" solver for the static, buckling and dynamic frequency analysis modules. It is a sparse matrix solver that fully utilizes the parallel processing capabilities of modern multi-core CPUs. The new solver is usually between 10 and 100 times faster than SPACE GASS 11. The most dramatic speed savings occur with jobs that have a large matrix frontwidth and lots of load cases.
The renderer graphics now fully utilizes the parallel processors on the graphics card rather than doing the graphics calculations on the main CPU. This means that deflection diagrams, bending moment diagrams, shear force diagrams, etc. can be scaled up and down smoothly regardless of the size of the job, even in fully rendered 3D mode.
The renderer has been given a major overhaul with a new user interface that now has almost all of the functionality of the traditional SPACE GASS window. This means that you can do everything in the renderer without constantly having to switch back to the traditional SPACE GASS window. The new functionality in the renderer includes:
user interface that can be configured with different skins and user
performance increases and no annoying delays or pauses.
and saving of jobs.
member and plate drawing and editing tools.
input and editing tools.
buckling and dynamic analysis.
and concrete design.
of all analysis result diagrams such as deflections, moments, contours,
to show fully rendered deflections rather than just wireframe.

Supported sections include Cees, Zeds, angles, tophats, channels, back-to-back Cees, CHSs, SHSs and RHSs. New cold formed section libraries for Lysaght, Stramit and Duragal have also been included.
The Portal frame builder now automatically creates all of the main connections in the building. They can then be used in the steel connection design module.
Allow a steel member design to be performed via a script file with the user being able to control the design groups, sections properties and load cases considered.
Allow exporting of steel member design/check summaries to a text file or MS-Excel/Access/Word file.
Various new script commands have been added that allow you to have more control over importing/exporting and analysis. You can also pause the script to see what stage it is up to at any point.
Released a Portal Frame Builder module for the modelling of portal frame buildings in SPACE GASS. It generates the full structural model plus dead loads, live loads, wind loads and steel member design data. The module supports gable (symmetrical and asymmetrical) and monoslope roofs, overhangs, knee braces, haunches, fly bracing, uneven frame spacings, openings, roof/wall bracing and end wall props. Wind loads are generated in accordance with AS/NZS 1170.2:2011 for all regions in Australia and New Zealand.
Released a Sea Load module for the calculation of wave, current, marine growth and buoyancy loads on submerged structures in marine and offshore environments.
This is a major new version that includes a new 3D renderer with full editing capabilities. Of course you can still edit your model in the traditional SPACE GASS window, however the editing tools in the renderer are generally more advanced and offer additional features over the traditional editing tools.
Some of the load input tools, design data tools and analysis results diagrams are not yet available in the renderer, however they will be added soon.
Member force and moment envelope reports can now be limited to the maximum and minimum values taken from just one end of the members rather than from both ends.
The analysis engine has also had a major make-over with finite and large displacement theory added, plus options for secant or tangent matrix solutions, residual or full loading, and residual convergence criteria. An "Auto" optimizer setting has also been added that senses the most efficient optimization method before the main analysis calculations begin. It removes the necessity for you to manually use trial and error methods to find the best optimization setting.
The standard libraries have been completely re-designed allowing non-standard and built-up sections to be saved. A new shape builder, moving loads generator with animated moving loads, and area loads generator have also been added.
Other major new features include on-screen notes, job attachments, dimensions, load combinations grid, load case titles viewer, measure tool, textures, gridlines, view selector, customizable toolbars and multiple undo/redo steps.

new plate element has been
added in v10.7. Plate elements can be quadrilateral or triangular

that this module will gradually be given full input, editing and viewing
functionality until it completely replaces the existing graphics system
in SPACE GASS.
