Different methods have been used recently to discover new families of a type of space frame: Double- Layer Tensegrity Grids (DLTGs). The main objective of this work is analyzing the process for the design and calculation of a specific deployable DLTG (DDLTG) at full scale (4x4x1 m) composed by 16 modules of 1x1x1 m. Three CAD/CAE tools were used for these purposes: ToyGL, Matlab/Octave, and Midas Civil. It was necessary to create an intermediate platform to exchange data and information between both tools, the ToyGL Processor, based on user-defined functions written in VBA for Microsoft Excel. The methodology was validated by comparing the results obtained by the first two software tools with those provided by Midas Civil. As a conclusion, ToyGL is reliable and accurate in terms of the definition of geometry, distribution of stresses and forces, reactions, states of self-stress, mechanisms, etc.
