What's New

Find out about the features recently added to SPACE GASS

SPACE GASS 12 is all about performance, plus a modern new graphical user interface with full editing, analysis, design, reporting and results display capabilities. Even though it looks different, all the tools operate in the same way as before and so you don't have to re-learn the program.

The new version also includes a 64-bit sparse matrix solver that supports parallel processing with multi-core CPUs, resulting in analysis speeds that are often more than 20 times faster than SPACE GASS 11. It also fully utilizes the massive parallel processing capabilities of your graphics card, offering fast, silky-smooth graphics.

If you already have SPACE GASS, click here to upgrade to the latest version 12.

Recent new modules include:
Reinforced concrete slab design
Advanced plate meshing tools
Portal frame builder (all new version)
Reinforced concrete column design
Reinforced concrete beam design
Steel connection design
Cold formed steel member design


  • Querying analysis result diagrams
    You can now query intermediate values along analysis diagrams by just moving the mouse cursor onto the diagram.

  • Fast hardware accelerated graphics
    The SPACE GASS graphics fully utilizes the hardware acceleration capabilities of most modern graphics cards which results in silky smooth drawing, selecting, zooming, panning, rotating and scaling.

  • 64-bit sparse matrix solver that supports parallel processing with multi-core CPUs
    SPACE GASS 12 includes a new sparse matrix "Paradise" solver that fully supports modern multi-core processors in full parallel 64-bit mode. It results in analysis speeds that are often 20 times faster than SPACE GASS 11 and sometimes over 100 times faster depending on the size and properties of the structural model. The speed increase is more pronounced with large jobs that have lots of load cases and large matrix frontwidths/bandwidths.

  • A new user interface with full editing, analysis, design, reporting and results display capabilities
    It is now possible to do everything in the new user interface, including full editing, analysis, design, reporting and results display. Of course you can still edit your model in the traditional graphics window, however the editing tools in the new interface are generally more advanced and offer additional features over the traditional editing tools.

    All of the wizards, drawing, input and editing tools are available in the new user interface.

    You can display or query the analysis results in wireframe or fully rendered mode, including animated mode shapes.

    If you want to change the appearance or colors of the program you can choose a different skin.




  • Steel member design results
    Steel member design results can now be displayed or queried. You can also hover over a steel member to have all of its steel input data displayed in a tooltip. When diagram values are displayed the steel member (group) number, load factor and governing load case are shown next to each designed steel member in the model.

    You can generate a complete portal frame building including the structural data, dead loads, live loads, wind loads and steel member design data. Note that if you have SPACE GASS 11.05 or later you can run the new portal frame builder in a free trial mode that lets you try it out.

    Key features include:

    • Fully integrated into SPACE GASS.
    • Generates the entire model from scratch, ready for analysis and design.
    • Generates all dead, live and wind loads plus combination load cases.
    • Wind region, recurrence intervals, shielding, topography, terrain categories (including transition zones).
    • Gable (symmetrical and unsymmetrical) and monoslope roofs.
    • Overhangs.
    • Knee braces and/or haunches.
    • Fly bracing.

  • A new shape builder
    Containing shape dragging, snapping, stacking, alignment and copy/paste. Shapes can now be specified as voids to easily model holes in your sections. New standard shapes have also been added for polygons, polytubes, triangles, Cees, Zeds, tophats and schifflerized angles. Line shapes that allow you to specify a line thickness and a series of points have also been added.

    You can show the dimensions of your sections graphically in the new shape builder.

    Shapes can be dragged and snapped together using reference points attached to each shape.


  • On-screen notes
    On-screen notes that can be positioned anywhere on or near your model or attached to nodes, members or plates.


  • Dimensions
    Dimensions that can be added to your model or to individual members or plates.


  • Measure tool
    A measure tool that lets you determine the actual length, component lengths and angles between any two points.


  • Job attachments
    An attachment tool that you can use to attach external documents, spreadsheets, drawings or any other files to your SPACE GASS job and embed them into the job file.


  • Drawing aids
    Important new drawing aids now let you align with other existing points or objects, snap to key intermediate positions along members, attach to existing objects, or align with existing members or global axes. You can even lock onto a node or member by briefly hovering over it and then begin drawing at some offset away from it. When aligned with an axis, member or point, you can also just type in the desired distance away your point should be.


  • Combination load cases
    A new combination load cases grid showing primary and combination load cases across the top and combination load cases down the side. You simply type multiplying factors into any cells to quickly build up your combination load cases in a very visual way. Rows for new combination load cases can be added as desired.

  • Moving loads
    A new moving loads generator incorporating animated views of the vehicles travelling over your model. Horizontal loads and moments can now be added to vehicles. Travel paths can now be drawn graphically, as can a loading area outside of which wheels are treated as inactive even if they are still within the ends of their travel path. A new vehicle editor has also been added, and vehicles are now incorporated into the standard libraries.


  • Manage load cases
    A load case manager now lets you copy, renumber or delete multiple load cases rather than one at a time.
