# What's new version 7

- The meshing parameters used and the GiD version are stored with the model. It is possible to list them with the Status command.
- Customization tcl variable GidPriv(TextOfVersion) in the ConfigureProgram.tcl file to show in the help (for example, to show the version of a problem type, not the GiD version)
- New tcl Order: ".central.s info GiDVersion" (returns the internal GiD version number)
- New tcl Order: info list_entities -more elements "selection" (-more also returns the element number, number of nodes and the volume)
- Use of enhanced memory to write the calculation file
- Draw of conditions over layer (the layer entities are drawn)
- New GiD-tcl events send to problemtype.tcl (proc EndGIDPostProcess {} and proc LoadResultsGIDPostProcess {file})
- New *.bas command *LocalAxesDefCenter (returns the center of the user defined local axis, similar to LocalAxesDef)
- Inline tutorials (see Help->Tutorials)
- Conditions Window: Entities->AllConditions (lists all conditions of the model)
- New *.bas commands *time and *clock to measure the time used to write the calculation file (useful for debug pourposes)
- The right buttons (hidden by default) now open the new conditions, materials, etc windows.
- Mesh extrusion enabled in the Copy window
- Split surface (menu Geometry->Edit->Divide->Surfaces->Split): used to divide a surface selecting the divide lines (these lines have to intersect the surface contours)
- New *.bas commands related to layers: (*Set Layer LayerName *nodes|elems, *Loop nodes|elems *OnlyInLayer, *NodesLayerNum *NodesLayerName *ElemsLayerNum *ElemsLayerName)
- Layer window updated

- Mesh only nodes (create elements with one single node)
- New import filter: ACIS V5.0 (files with ".sat" extension)
- Window to edit nurbs lines and surfaces in "free-form" mode
- Option TangentNurbsL, to force two adjacent nurblines to be tangents
- Boolean operations (union, intersection, substraction) in "Solids 2D" (surfaces in same plane)
- Variable 'MaintainOldMesh', depending on its value the old mesh is not deleted when creating a new mesh (used to mesh separate objects by parts)
- Preference option to force the meshing of entities even if its higher entities are meshed.
- Nastran read enhanced
- Background mesh file, to assign mesh sizes (adaptative remesh)
- Layer commands in the .bas file (commands: *Loop Layer, *LayerName *LayerNum)
- New HTML help
- Utility to draw dimensions (vertex, distance, center, angle, text)
- Selection point: option center (arc or nurb with arc shape)
- Draw boundary mesh: interface of material is considered boundary
- Layers: classify in Front or Back (hide) containers
- Multiple surface intersection
- Division of a nurbs surface selecting the lines to break
- Selecting entities: new options AddToSelection, RemoveFromSel or SwapSelection
- New selection filter window
- New filter selection by element type (e.g. filter:ElementType=TRIANGLE)
- Creation of a Boundary Mesh from a higher mesh (e.g. triangles from a volume mesh)
- RJump mesher: experimental option to create elements jumping between tangent contiguous surfaces
- Nurbs surface creation from a cloud of points or level curves (topographic applications)
- Now Conditions can be applied over layers
- HTML suport to include help in your problem types
- New TCL functions to customize menus
- New command of the batch file. *****TCL "tcl command", to execute a tcl command in a batch file.
- New options available ("Element size" and "Minimum Edge") in the MeshQuality window.
- In the MeshQuality window, if you double click on a value, the elements below/over this value are selected.
- Option DrawSizes of the Meshing menu. Different assigned sizes in a mesh are represented in different colors.
- Optimization of the Edit Nurb Line/Surface tool.
- Option SendLayToUse in the contextual menu sends the selection to the Layer in use.
- Option Smoothing in the mesh preferencies.
- Option DrawHiger in the Utilities menu, it draws superentities in different colors.
- New command of the .bas file, *ElemsNnode. This command returns the number of nodes of the actual element. (Useful in loops of elements)
- Option Collapse Edges. It has to be applied over a mesh, and it joins nodes which are connected by edges shorter than the Import Tolerance value.
- Now it's possible to invoke GiD with option -n2. That option runs the program without any window but the Tk library is loaded.
- New Tcl function available, GiDVersionCmp, useful to check the version of the GiD which is currently running.
- New command of the .bas file, pow(a,b).

- 'Color Window' in contour options added.
- Legends, comments and axes can be moved around the screen.
- Enchanced Gauss Points support
- JPEG and MJPG support.
- TecPlot ascii postprocess files supported.
- Femap neutral postprocess files supported.
- New Results file format: more understable.
- New results visualization types: contour ranges with text labels.
- Several improvements:
  - more acurate smooth render
  - more acurate cut elements generation
  - better management of holes in result values
  - high resolution printing
  - better gauss points management: contour values that cannot be extrapolated to the nodes, are drawn as coloured balls
- Points support, with variable radius and textures.
- Color improvements for vectors, stream lines, contours, sets, ...
- Separation of sets corresponding to materials or layers in preprocess.
- Names on Volume, Surface and Cut sets.
- Transparent and massive properties independent for each set.
- Added List status of sets, nodes and elements ( entities) with results.
- New sets and Results can be merged into the current ones.
- New output posibilities: VRML, animated GIFs, PNG, AVI, pictures of multiple windows.
- Automatic results comments.
