Model tree (left)

Previous pageReturn to chapter overviewNext page

The model tree contains all available geometry parts listed in a tree structure, whereby their visibility can be switched on or off alternatively. All visible elements are exported, if the model is saved as IGES, STEP, STL, Parasolid or BREP - see Export.

Display properties

The elements selected in the model tree are highlighted in the 3D view. The selection can be cleared by pressing the <Esc> key.

The attributes can be defined by right click:

• Display mode: Wireframe, Shaded surface, Shaded surface with edges

• Material

• Color and transparency

• Check/ uncheck all sub-elements of the selected element

• Show geometric properties of selected element in extra dialog:

ovolume, density, mass, center of gravity and static moments of inertia for solids

oarea for surfaces

olength for edges

• Export selected element as IGES, STEP, STL, Parasolid or BREP.

Imported geometry will be exported in its transformed state (this option is not available for STL imports)

 

For elements in the Imports section only:

applies user defined geometric transformations (see below)

removes selected import from model tree and 3D view

removes all imported elements from model tree and 3D view

Model tree structure

The model tree has 3 main sections:

1) Section Components

contains all components of the project with the following sub elements:

Impeller/Stator

Volute

Meridian

Spiral

Mean surface

Diffuser

Blade

Cut-water

CFD setup

CFD setup

If an element contains child elements, it can be expanded by clicking on the collapsed element symbol ().

Each single element without child elements can be selected () or unselected ().

Each single element with child elements can have 3 states:

The element and all child elements are selected.

The element and not all child elements are selected.

The element is unselected. Child elements might be selected.

An element is visible in the 3D view, if it is selected and all its parent elements are also selected.

Note: If the <Ctrl> key is pressed while selecting an element, all child elements are selected, too!

2) Section Geometry

contains all basic geometrical types:

Points

Curves

Surfaces

Solids

This allows:

to select all objects of a certain geometrical type. In the 3D view, only those elements become visible, whose parent elements are selected also.

to modify the display properties of all currently visible objects of a certain geometrical type.

3) Section Imports

This section contains all imported geometric models including CFturbo components of reference projects or simply imported 3D models.

Visibility and render properties for imported models can be modified in the same way as for components of section Components.

The option Transform geometry is intended to help align imported component models with the project model to make visual comparisons of the model shapes more convenient. To this end, any number of simple transformations can be applied via the dialog that opens when Transform geometry is selected.

The Transform geometry dialog allows the application of four different types of geometric transformations, accessible by clicking on the corresponding symbols (from left to right: translation, rotation, uniform scaling, mirroring).

Translations can be applied iteratively along the coordinate axes.

Rotations can be applied iteratively around the coordinate axes.

Uniform model scaling is applied in absolute (percentage) terms.

Mirroring is toggled for the models coordinate system in all three coordinate directions.

To apply a transformation to the selected parts, select a transformation type, set its parameters and click the Apply button (or hit Enter).

The model transformation can be reset to the state which it was imported with by clicking the reset button.

Useful transformations for an imported model can be saved for later use by exporting the model with its current transformation via the context menu (Export as, see above).

Model states

Model states contain the properties of all tree elements (except imports). Several model states can be managed via the controls above the model tree.        

Select existing model state

Save model state

Rename selected model state

Add new model state

Delete selected model state

The following predefined model states cannot be modified:

"Default"        

The default model state

"Default + CFD setup"        

The default model state with CFD setup visible

"Flow domain solids"        

Only solids are visible that belong to the flow domain

"Material domain solids"        

Only solids are visible that belong to the material domain

"Component colors"

Every component is displayed with the color defined in the Components view

For performance reasons, model states do not contain the state of each individual 3D object, but only to the level of distinction between different geometrical types (points, curves, surfaces). Therefore, e.g. all curves that belong to a "Curves" object share the same properties.
