THEOREM'S MULTI-CAD REMOVES COST & UPDATE ISSUES OF WORKING WITH BOTH CATIA & NON-CATIA DATA IN SINGLE PRODUCT 
DESIGNS.
“Multi-CADV5 enables non-CATIA data to be simply incorporated within a CATIA V5 environment.”
Theorem's Multi-CAD V5 product removes both the cost and the complexity of working with both CATIA V5 data and non CATIA data on a single project. Allowing the operator to access the data seamlessly from within CATIA, it removes the headache of importing data from UGNX and/or Pro/E into CATIA by eliminating the translation bottlenecks that add costs to both new and evolving product designs.
Multi-CAD reduces design costs by enabling the CATIA V5 user to incorporate non-CATIA V5 parts and assemblies, simply, within the CATIA V5 environment. This approach contrasts favourably with the traditional, time- intensive and costly process of translating non- CATIA V5 data to CATIA V5 using a standard such as STEP AP203, or a direct database translator.
A major drawback with the above processes is recognising when a design change takes place in non-CATIA V5 data, and managing the process of updating the CATIA V5 representation to take into account the changes once the initial translation process is completed. A further issue is that the designer has no control over when the data is translated, if it is carried out as a separate process.
Theorem's Multi-CAD V5 solution overcomes these problems, enabling CATIA V5 users to incorporate non-CATIA V5 parts and assemblies within the CATIA V5 environment - without external translators. Working within CATIA V5, the user simply selects the “Insert” tab at the top of the CATIA screen and moves to the “Existing component” selector on the ensuing drop down menu.
This is pure CATIA V5; no new interface, and nothing new to learn. However rather than selecting an existing CATIA design, the user selects a non CATIA V5 part or assembly; this then appears on the CATIA V5 design tree.
What has actually happened is that the “Insert existing component” command has not only selected the non-CATIA V5 part/assembly, but it has also run the Theorem Multi-CAD V5 application, which has drawn the data into the CATIA design tree. The speed of modern hardware and the reliability of the Theorem software mean that the user doesn't even know that a translation has taken place. This is true interoperability in action.
Multi-CAD V5 is not only easier to use and more cost effective, it is also much more secure than a traditional ‘translate and import' process, in which there is never a link between source and translated files.
This separation between CATIAV5 and imported, non- CATIA V5 data, when employing external translators, has always been a major problem for users, in that any changes to the non-CATIA V5 data would not be updated in the CATIA V5 design. However, with Theorem's Multi-CAD product, CATIA V5 maintains and manages the links with the original files. Consequently, if there are changes within the non-CATIA V5 components or assemblies, these will be automatically reflected in CATIA V5 itself.
