CAD IMPORT / EXPORT


SolidWorksFile > Import > CAD

• Support added to import SolidWorks CAD models.

• Design parameters from SolidWorks part and assembly can be imported and DOE study

can be performed.

Sample model

Models/SolidWorks


Other enhancements

Ç AD

• Support added to drag and drop the Catia models.

• Support added to export wire and general bodies as Parasolid geometry.

CAD Through Translation

• Support added to import Creo 4.0 and CATIA R28 models.


USER INTERFACE


Assembly BrowserModel Right click > Save Geometry

• Option added to save the CAD geometry. This will be mainly useful, if we regenerate the

design parameters then we can save the updated CAD geometry.


Function Usage LogFile > Help

• Icons for each tool is added for easy identification of the tool.

• Dialog resize supported.

• Reset button is added to clear usage log.


Mouse SettingsFile > Preferences > System

• Abaqus CAE, ANSYS Workbench and SolidWorks Mouse settings can be set in SimLab.


Other Enhancements

• Support added to delete the nodes from point bodies.

• Option added for the following

• Middle mouse click to switch from one item to another

• Spacebar button is used to select Apply

• Enter button is used to select Ok


• Following options from render mode are added in the form of icons.

➢ CAD Wireframe

➢ CAD Face edges

➢ FEM Face edges

➢ Element edges

• Turn on the CAD wireframe mode will display the wire frame in body color.

Grid MeshMesh > Modify > Grid mesh

• Support added to create grid mesh for three sided faces. Mesh seeding can be changed

interactively.

• Mesh transition is handled while changing the seed numbers in the mesh.

Note: Left click for decreasing seeding , Right click for increasing the seeding and middle click to enter the value of seeding.

Sample model

Models/GridMesh


• Option added to project the input face to CAD face during grid mesh.
