After a few development challenges, TP4 is ready for React users to review and once again provide feedback. It took us a little longer this time, as we were aligning with the Dynamo 1.0 release, and there were some items we wanted to make sure we got into the release for you to use.
With TP4 it’s possible to define structural grid axes in a project. A dedicated command icon is available at the end of the Model ribbon tab:
Grid lines can be defined on the XY plane, both in the 3D view and on the Plan View. Apart from a direct graphical definition on canvas, it’s also possible to define a set of axes by entering the Offset distance in the Dynamic Input control. The offset is measured from the last inserted grid axis:
Grid axes are displayed in the Object Inspector and their properties, including the name, can be changed in a properties dialog.
Grid axes are special objects and not all operations are available for them, such as the Copy command in the ribbon. To copy an axis a special command from its contextual menu should be run:
Working in the 3D space, grid axes can be displayed on any Z level specified in the control available on the canvas. While drawing structure elements, you can change levels to snap to grid axes on different levels.
React Structures TP4 lets you define straight grid segments. Arc or multi-segment axes definition is not yet available.
Trim and Extend
The Trim and Extend commands are now available in Modify tools. Both commands work for linear members.
Members for edition can be picked one by one or by multi-selection.
The Intersection command allows to quickly divide linear members at intersections.
Dynamic Input improvements
Dynamic Input allows inputting numerical values needed for coordinates or editing commands. Dynamic Input modes can be easily changed using keyboard shortcuts or in a menu opened by pressing “Down Arrow” when the dynamic input control is active:
For different tools, different dynamic input modes are available. For definition of structural grid axes a default mode is an offset distance. It can be changed any time when a tool is active.
Unit symbol has been added to input boxes as well as unit conversion (e.g. user can enter value in inches and it will be converted to foot)
Interaction enhancements and Graphical improvements
Preview is very useful both for model definition and for the modify commands. The new preview for Trim and Extend and improvements to already available preview display are available in this tech preview.
React Structures TP4 includes improvements in visualization of dynamic input modes. Preview displays in the 3D View and Plan View.
Snaps symbols are more visible now and unified with other applications.
Snapping to structural grid axes and improvements in general snapping mechanism have been implemented in React.
- Stories and Structural Grid visibility in Object Inspector
Switching on and off an Eye icon in the Object Inspector allows displaying or hiding Stories or Grids in an active viewer.
- Levels definition
Automatic levels (Z coordinate value) are defined at a bottom and top of each story. Additionally, any Z level can be added to the list. These coordinates help to navigate in the model and quickly set a reference level for a plan view. It’s enough to click on the control on the canvas and input a value. It’s added to the list and can be removed any time.
- Dynamic Input icon on the status bar
Apart from a function key F12, the Dynamic Input control can be now switch on and off using a dedicated icon on the status bar.
- Cursor stepping
For the Plan View grid dots are switched off by default now. To facilitate model definition on canvas, cursor is however stepping into whole numbers now.
Obviously, entering fractional values is possible in the dynamic input control.
- Dialogs’ graphics
Next graphical improvements are available in React now, e.g. pictures in dialogs for a light team are changed.
- Ortho mode
React TP4 contains improvements in Ortho mode. Main changes relate to Ortho mode switched on in the 3D view and while edition operations.
- Deformation visualization
In React TP4 you can display exact panel deformation together with panel interior. Undeformed Structure visualization has been changed to less disturbing. Now you can see only a gray outline of undeformed model while deformation is displayed.
To facilitate stepping in React Structures, the application has been equipped with a Command Search tool. There is also available simple tutorial in the learning materials now.
The Command Search field is displayed at the top of the Application button menu. Search results can include ribbon commands, dialogs or status bar commands.
As a search result, the command location is displayed and a feature can be run directly from the search dialog.
Tutorial is available directly from the program landing page or from the “Learn & Share” ribbon tab.
New version of Dynamo in TP4 is compatible with Dynamo Studio 2017 and Dynamo 1.0 released recently.
