- In the «Select All» mode (Ctrl+A), only what is currently visible on the workspace will be selected. That is, the operation of view filters is taken into account.
- In the «Status Bar» the display of the size of a rectangle or the radius of a circle has been added when the «Box Selection» operation is working (both in the selection mode and in the deselection mode).
APM Studio
Pre-and-postprocessor of 3D solid and shell models for finite element analysis
- New ribbon interface.
- Large strain/displacements + material non-linearity analysis has been added.
- The model tree has been updated and restructured. By default, it groups information in the form of the sections: Planes, Materials, Contacts, Connections, Restraints, Loads, Finite element mesh.
- For the elements of the model tree, the option «Exclude from analysis» has been added on the right mouse button. This option works on all elements and operations in the tree. For example, turn off a part or load. When a part is excluded from the calculation, all operations related to it are also excluded from the calculation.
- Added the ability to simultaneously edit a group of contacts. Select a group of contacts in the tree, select «Edit» using the RMB and change, for example, the contact type.
