The Menu Tree 

• The menu tree is where all user data is created, loaded and 

saved. 

• Right clicking on any existing entity will bring up a series of 

options such as new, load, save, export etc. 

• The right click menu adapts to the selection clicked. 

• The user can click on one or more entities which will also 

change the right click options available. For example right 

clicking on a list of materials (selected with the shift key) and 

selecting the duplicate function will duplicate these materials. 

Right clicking on the Materials entry will duplicate the entire set 

of materials. 

• This functionality is common throughout the CDS3.0 menu 

environment allowing easy creation of materials, laminas, 

laminates etc. 

• You can select multiple items in a row by holding the shift key 

or discrete items with the control key pressed when selecting 

items. 

• Note that you can only multi select items on the same level and 

sub menu.

Stacking Input 

• Clicking on the Stacking Tab (or selecting a laminate in the menu tree) opens the Stacking 

section were laminates are created and edited. Like the materials section the user can view 

a single laminate in standard view or observe and edit laminates in the global table view. 

• The standard view table includes a table showing the current laminate and offers a number 

of right click options

Stacking Options 

Populate Laminate: Use this function to quickly populate a laminate by populating a laminate with the 

selected Number of plies. The best approach is to first select a material (by right clicking the table) and 

assigning it to the first ply. Then use the populate laminate function to add N plies to the laminate. 

Assign Material: Use this function to assign a material to a ply. The materials are filtered by type in the 

selection for ease of selection. 

Add Ply (Plies): The selected ply (or plies by selecting and holding the shift key) on the table can be 

added to the laminate to quickly add plies. 

Delete Ply (Plies): The selected ply (or plies by selecting and holding the shift key) on the table are 

deleted. If all plies are deleted then the laminate resets to 1 ply and asks for a material to be selected. 

Symmetry: Right clicking this option makes the laminate symmetric. If one ply is selected then the 

entire laminate is made symmetric. If two or more plies are selected (using the shift key) then those plies 

are made symmetric 

Common Ply Orientations: Depending on the number of plies in the laminate the user can select a 

series of common laminate orientations to populate the laminate. The common angle input at the top of 

the table is used to assign less common +/- orientations to this function. Note the laminate is populated 

with integer cells of these common ply orientations and the laminate may not be symmetric after picking 

this function. (Click the Symmetry button to restore symmetry after this operation) 

Fill Column: Fills the selected column with data from the row selected. This works for all columns 

including material selection. 

Invert Selection: If one ply is selected then the laminate is inverted, if more than one ply is selected 

then the selection is inverted.

Opening and Saving Data in CDS3.0 

• Data is saved and loaded to the CDS Menu by right 

clicking any item on the tree 

• All files are saved to text (tab delimited) spreadsheet 

format irrespective of what data is saved. 

• When opening an spreadsheet the user is presented 

with the contents of the file 

• The user can then select some or all of the contents 

to load into the current analysis. 

• These files are generated locally so all propriety 

content is protected. 

• Databases have associative hierarchy, i.e. if you 

save a laminate all materials within the laminate are 

attached and stored for retrieval

Summary 

• In summary, CDS version 3.0 is an advanced software application for designing and analyzing 

composite structures. 

• CDS3.0 has built in database functionality, parametric analysis features and multi analysis 

connectivity, i.e. thermal and structural analysis coupling. 

• The new menu tree environment can be used to quickly store and retrieve data generated within 

the software. 

• CDS3.0 comes with example materials, laminates and analyses to quickly get started 

• The new “Data” module provides built in data reduction capabilities directly within CDS3 

• Right clicking any data set saves to the clipboard or directly to Microsoft Excel. 

• With this software, an designer engineer, process engineer or student can quickly determine 

the effective properties and response of composite laminates, conduct micromechanics 

calculations, as well as virtual process simulation and optimization.
