• Changed the TENSION/COMPRESSION color convention in the simplified axial diagram as many users were getting confused. Now RED (inward arrows) means the member is in compression while GREEN (outward arrows) is when the member is in tension.

v2.0.2 - 12 January 2017

• NEW: View table(s) of results and export to CSV (access in "Output" → "CSV Results") after solving.
• Various improvements to the datasheet including a bug fix where large sets of data (more than 1000 rows) could not be viewed. The datasheet will now have pages when the list becomes too large.
• You can now solve unmeshed plates if they have only 3 or 4 nodes.
• Section names now show up in S3D. Sections made up of database shapes only will use the database name. Others will use the height x width to name the section.

• NEW: Added more mesh parameters to control structured quad plate meshes.
• Fixed issue with plates results scale.

v2.0.0 - 18 November 2016

• NEW: Plates added. Model slabs, walls, tanks etc. Create plates by clicking between nodes or simply list nodes and then mesh them before solving. The plate solver uses shell elements which means there is both membrane (shell) and bending (plate) components.
• NEW: Pressures can be added to load plates either in local plate axes or the global axes.
• NEW: Member and Plate Offsets have been added. This allows you to create rigid connections and connect members/plates that do not meet at their centrelines. These offsets are local to the member/plate.
• NEW: Interactive and fully integrated 3D Renderer. The new 3D Renderer is more integrated in the software and can even be used to build and edit the model. Visibility settings have also been improved for the 3D Renderer (e.g. you can now make members/plates transparent and view nodes).
• NEW: Advanced User Interface (UI) switch has been added to many of the left menus to hide the complex fields that only get used by advanced users.
• NEW: Applying loads and supports to multiple nodes/members/plates can easily be achieved by listing them as comma separated or as ranges (e.g. 1-3 or 1,2,3 or all).
• NEW: Visibility Settings moved to the right view controller for easier and quicker access.
• NEW: Add distributed loads in the local member axes instead of just the global axes.
• NEW: Integrated the new SkyCiv Section Builder (SB) which supersedes the old section builder.
• NEW: Solver speed improved by around 600%.
• NEW: Faster buckling analysis, however this leads to a poorer buckling shape. Click 'Settings' → 'Accurate Buckling Shape' to solve a more accurate shape which will solve in the same time as previous versions.
• NEW: Graphical speed and responsiveness improved for larger structures.
• NEW: Improvements to the 'Repair Model' tool including a warning if a large structure has been detected due to entering incorrect units (e.g. entering node coordinates in millimetres when the software is expecting metres). Additionally a default section will be added if the user forgets to add one (useful for students who do not know the sections of their structure but just want reactons, shear, bending and axial results).
• NEW: 'Materials' have been separated from 'Sections' and must be defined outside of the section builder. However, these materials can be used within the section builder. This suits the new plates and composite sections. Old files created before v2.0.0 should automatically be adjusted for these changes.
• NEW: Files can now be auto-saved (activate this from your 'Account Settings' → 'User Settings' → 'File Manager Settings' → 'Autosave Files'.
• NEW: Warnings are now shown if you attempt to exit the software without saving your work first. Also a '*' symbol will be displayed next to your filename while you're working if you have unsaved changes.
• NEW: 'Clear All' button for datasheet can be used to fully clear a datasheet.
• Fixed bug in PDF and TXT reports where the min/max stresses were not being highlighted.
• Improvements to torsion stress and shear stress calculations (now based on shear area), as well as stress of asymmetric sections courtesy of the new SB.
• 'Settlements' moved from the left-menu to the top-menu under the 'Advanced' menu. The can also be accessed from with the 'Supports' left-menu.
