3D MODEL

The following actions are available by the buttons of the 3D Model tab. They are used for visualization only and do not affect the geometry model.

General

Copy representation to clipboard

Print representation

Save representation as PNG, JPG, GIF or BMP

Save representation as 3D-PDF

Visible 3D-model data is transfered to a PDF-document, enabling the user to distribute or archivate a 3D-representation of CFturbo-models.

The PDF-document contains a 3D-viewer, including a model-tree as well as various 3D-capabilities (e. g. measuring, clipping, display options). It can be opened with PDF-viewers supporting 3D-content (e. g. Adobe® Acrobat® Reader, not possible in internet-browsers without certain plugins).

If the PDF-document is opened in a PDF-viewer and a static picture is shown instead of a 3D-model, then:

1) ensure using a PDF-viewer supporting 3D-content
2) ensure activating 3D-content in the settings of the PDF-viewer
3) click on the static picture to switch to the 3D-content

An example of a 3D-PDF visualized in Adobe® Acrobat® Reader DC is shown below:

Import external 3D geometry for visualization

The 3D Import enables the user to view 3D data in IGES, STEP, STL, Parasolid and BREP format or of CFturbo-projects (*.cft) e.g. for comparison with the current design or for redesigning. Geometry data is shown in the 3D Model and can be transformed and exported.

If the import consumes a lot of time, a lower resolution can be selected (see "Settings" below).

View

Fit view (zoom all geometry to visible region)

Reset view (default position)

Load view from file

Save current view to file

Settings

Switch coordinate system on/off

Switch scale system on/off

Set background color

A uniform rotation of the impeller around the z axis can be generated, whereby the velocity can be influenced by the track bar.

Select resolution of curves and surfaces (affects display)

Coarse

Middle

Fine

Define line width for points

Define line width for curves

Set number of surface isocurves

Clipping

A clipping plane for x=const., y=const. or z=const. can be defined and optionally displayed. The position of the clipping plane can be adjusted.

The direction of clipping (visible clipping side) can be switched.

BLADES

These actions are used for visualization only and do not affect model geometry.

Please note: The following options refer to the currently selected component of the project.

Single blade

 

Blade passage

 

Display a single blade passage bordered by 2 neighboring blades.

All blades

 

Display all blades of the selected impeller or vaned stator.

 


Area

 

Display an approximately perpendicularly flown through area between hub, shroud and two neighboring blades for the currently selected component. The position of this area can optionally be fixed to the location of the throat area (Fix to minimum). Otherwise, it can be slided to any reasonable position within the blade to blade channel with the help of the track bar Section Position.

 

By pressing the button Show progression a window is opened, in which the value of the cross section is displayed in dependence on the position (see here for changing position variables) between leading edge and trailing edge. The current position as well as that of the throat area and the maximum sphere diameter are marked with special symbols. In the lower part of the window some measures for the current position are displayed.


Sphere

 

The sphere represents a particle with the highest possible diameter that can be conveyed through the blade passage.
