  • Steer the models using the CADMAI relation management
  • Import and export data
  • Interact graphically (e.g. dynamic rotation)
  • Start CADMAI animations

You cannot:

  • Design interactively
  • Show the CADMAI statusbar, the toolbar and the structure editor

The WPF Control supports WPF specific enhancements like routed events and dependency properties.
The licensed version of the control supports the full functionality like the other CADMAI Controls (e.g. CmiDotNetControl) with interactive design possibilities.
If you want to use the WPF control in Expression Blend, you have to set the start folder of Expression Blend (Shortcut dialog -> Start in) to the CADMAI installation directory.

XAML Export

  • 3D CADMAI models can be exported to XAML format and can be used as standard WPF 3D model content (MeshGeometry3D).

Miscellaneous

  • Sweep Solid along 3D curve (s_sweep_3d)

What's New in CADMAI Version 4.3

Unicode Support
UNICODE characters can be used in the UI, in graphic windows, for CADMAI entities (Texts Symbols,Dimensions) and for model file names.

Korean UI
Korean language resources have been added.

Component mating
Components can now be re positioned and/or re oriented using mating actions.

Font support
CADMAI now supports the definition of different fonts in a model (based on the installed Windows fonts). These fonts can be used to draw text content in the graphic window. A 3D representation can be established by adding a depth value. UNICODE characters are supported.

Miscellaneous

  • The web download directory for the controls can be set by the property WebDownloadPath
  • CMD_CLEAR_DOWNLOADS command for the controls deletes all stored downloads in the WebDownload directory
  • Support of visible edges for section views

  • A new sample shows the usage of 3D models in MS-Word documents (similar to 3D PDF)

What's New in CADMAI Version 4.2.1

  • CADMAI Web Browser Plugin now supports Firefox 4 and Google Chrome 12
  • Bug fixes

What's New in CADMAI Version 4.2

2D UI Objects
Version 4.2 introduces a new type of basic objects which support the design of 2D user interfaces.
These UI objects can be used in combination with the geometric objects (lines, solids,...) and non geometric objects (layer, variables,...)

The following UI objects are currently available:

  • 2D buttons
  • Images
  • 2D Text

These 2D UI objects are stored in a CADMAI model and are presented parallel to the 3D objects. This technology can be used to create user interfaces which combine 2D and 3D objects. A sample which uses a mixed 2D / 3D user interface which is optimized for touch input on taplett PC's is included.

Support of multi touch gestures
Under Windows 7 multi touch gestures for panning, zooming and rotating are supported for all CADMAI windows on touch screens.

Web Browser Plug-in
Beside the ActiveX and the DotNet control version 4.2 provides a web browser plug-in, which can be used for Firefox and other web browsers.

New Actions
Beside the UI Objects the following new actions have been defined:

  • 3D intersection point Line Face (p_int_line_solidface)
  • Mass center of solid (p_solid_center)
  • Contour from section (named_contour_sectucs)
  • Set entity action parameter via an animation command (anim_edit_par)
  • Restore entity color (ent_restore_color)
  • Recursive save operation for assemblies (CMD_RECURSIVE_SAVE)
  • Reset operation of the active window incl. component unload (CMD_RESET)
  • Reload operation for the active model from hard disk (CMD_RELOAD_FROM_DISK)
  • Component activation out of the "Loaded Component list"

Release Notes for CADMAI Version 4.1

New actions for component placement
Components can be positioned additionally to 3D points and to user coordinate systems.
The target points / coordinate systems can be categorized to restrict the placement of components to specific positions.

After positioning, the components can be translated or rotated by additional actions.

The origin, the orientation and the category can be defined for a CADMAI model, which steers the component placement of this model.
Additionally a solid can be defined, which is used for collision detection when the model is placed in an assembly.
The collision with other collision solids is dynamically calculated during user interaction.

Creation of assembly containers
Models can be saved inclusive all external references to a compressed file.
Hereby complete assembly structures can be collected into one file which can be loaded e.g. through the internet

New assemble mode
A new slider "Loaded components" is available in the structure editor which shows all sub components for an assembly.
Using the right mouse button the following mouse actions are available:

  • Load components into memory
  • Position component interactively
  • Position component freely
  • Position component to point
  • Position component to UCS

By selecting one of the last four entries the assemble mode is activated.

When the user interface is switched to the new assemble mode the behavior during mouse input is changed.
In the assemble mode, loaded components can be positioned, copied and deleted dynamically by the user (for more information please refer to the online help).

Enhancements for the controls
All relevant settings of the CADMAI environment have been made available for the controls (ActiveX and DotNet).
Since the settings can steer the appearance of the CAD windows (e.g. view settings) the CAD windows have to be created explicitly with the method CreateCadWindows().

API
The following additional mouse events are fired from the CmiWindowsApi or the controls to the host application.

  • Mouse over a CADMAI object
  • Left mouse button pressed
  • Left mouse button released
  • Drag operation with a pressed mouse button

To point out the possibilities of these additional events the following five examples have been created as local applications and as web browser implementations:

4 Wins 3D
This sample shows in form of the well known game "4 Wins" how CADMAI components can be positioned dynamically with the mouse from the host application.
The game is realized in 3D

Parametric changes
Shows how parametric changes of a model can be performed by mouse and dialog input

Poke Game (similar to LEGO)
Shows how the new assemble mode can be used to design models by assembling simple pokes.
Dynamic collision checking can be used to avoid impossible poke placement

Switch Plate
Shows how a 3D user interface can be designed.
A switch panel with rulers, sliders and buttons can be operated by mouse input and steers related controls of the host application (and vice versa).

Tic Tac Toe 3D
This sample shows in form of the well known game "Tic Tac Toe" how mouse feedback can be used to steer user defined CADMAI objects.
The game is realized in 3D (but player 1 always wins ;-) )

All samples are available with source code (C#/HTML+JScript).

The web samples for Internet Explorer can be found at http://www.cadmai.com/WebApiSamples/Control/webapisamples.html

Miscellaneous

  • An update possibility at the push of a button is established by using a new installer.
  • The licensing has been transferred from the CAD into a new application
  • CADMAI 4.1 supports a per user licensing.

There is no need to license hardware components (MAC-IDs) anymore.
The existing licenses are valid for version 4.1 and must be re entered after the installation.

What's New in CADMAI 4?

New user interface
CADMAI Version 4.0 contains beside the classic user interface (CmiNativeUI.exe) a new application (CmiRibbonUI.exe) based on the .Net Framework and the ribbon technology. The Ribbon based UI uses different color schemes which can be configured by the user.

OpenGL Shader support
With version 4.0 CADMAI supports beside the standard OpenGL rendering pipeline the programmable OpenGL rendering pipeline by the usage of GLSL shader programs.

The following features can be used with CADMAI shader programs:

  • Multiple rendering passes
  • Vertex, Fragment and Geometry shader
  • DDS file support
  • Environment mapping
  • Multiple texture units
  • Volume textures
  • Procedural textures
  • Definition of uniform parameters
  • Tangent and Binormal attribute parameters for bump mapping
  • Override of standard OpenGL functionality (blending, culling, ...)
  • The shaders can be used to render 3D objects (Solids, Solid faces and Greps) in combination with the standard OpenGL rendering.

CADMAI Version 4.0 includes more than 30 shaders, which are available in source code and can be adapted to the user's requirements. In addition to that they can be used as templates for new shaders which can be made available in CADMAI by configuration only. Shaders can be used in the CmiObjectApi and the CmiWindowsApi and are thus available in all applications which use these API's.

The following list is an extract of the delivered CADMAI shaders

  • Metal (brushed, matt, polished, ...)
  • Stone (marble, polished stones, grit, procedural stone textures, ...)
  • Glass
  • Tissue (velvet, ...)
  • Wood (polished and matt)
  • Illustration (cartoon, Gooch, ...)
  • Effects ( erosion, mirror, ...)
  • Surface structures

To be able to use shader programs, the installed OpenGL version must be greater than 2 and the GLSL version must be greater than 1.
The determined OpenGL version numbers are displayed in the CADMAI Help dialog.

Enhanced geometry storage in the model files
With version 4.0 it is not only solid geometry which can be stored in the model files. A new setting additionally saves the geometry of FEM meshes and view derivations into the model file for performance improvements. This leads to faster loading of the model, because the geometry does not have to be calculated. It also leads to larger model files so to keep the model files as small as possible the geometry is stored compressed.

Windows 7 compatible
CADMAI Version 4 works with Windows 7 (32 bit and 64-bit).
