In times of global and simultaneous development processes, tools that support engineers in managing their complex design data are becoming increasingly important.

With xCompare, you can analyze CATIA V5, SMG and JT data to find differences in two revisions of products, parts and drawings or to verify the conversion process. It trances all design changes in CAD models, far more than just geometry differences.

Benefits - Why Choose xCompare?

Save time with comparing models

The model comparison can either be done in CATIA or in batch mode and does not have to be carried out manually.

Increase in reliability

Manual review can involve human error, so there is a risk that changes in complex models will be overlooked. xCompare guarantees that all changes will be found.

Fulfillment of legal or internal regulations for documentation

In the case of data conversion and long-term archiving, legal or internal company regulations may require that the generated or archived model data match the original data data of the CAD system. xCompare V5 / JT and V5 / SMG ensure this check.

Customizable Configuration File

Users can create new or edit existing configuration files dependent on use case. The Configuration file can be used across releases to have uniformity in check parameters and results.

Solid Release Cycle

Numerous releases (major and maintenance) available throughout the year. Releases can be adapted to the customer timeline.

Features of xCompare:

Traceability of all design changes to the CAD model

xCompare compares geometry information (e.g. size, surface, center of gravity), and program checks (e.g. colour properties, layers, point, line types and referenced objects). When checking model structures, xCompare takes into account elements, attributes and parameters.

Supports CATIA V5, JT and SMG

xCompare V5 / V5 supports single parts (CATPart), assemblies (CATProduct), drawings (CATDrawing) and Cgr. Using xCompare V5 / JT, the CATIA V5 model is compared with the converted JT model. xCompare V5 / SMG analogously ensures the conversion process from CATIA V5 to CATIA Composer format SMG.

Supports the 3D master process and long-term data archiving

The feature-based comparison recognizes all design changes including changes to Functional Tolerancing & Annotation (FT&A) playing an important role in the undrawn process. When validating data conversion, xCompare ensures no unacceptable differences have arisen interfering with subsequent processes and data archiving.

Fully integrated in CATIA or LiteBox3D

All xCompare V5 products are integrated in CATIA V5. V5 models can be read directly via the CATIA CAA interface without model conversion. The SMG or JT data to be compared are also read using CAA or TECHNIA’s own APIs based on ISO standard 14306: 2012. The JT / JT model comparison takes place within the TECHNIA JT viewer LiteBox3D.

Model comparison without conversion directly on the original data

The xCompare solution has the advantage that the original data can be validated directly without prior conversion into a manufacturer-specific data format. This guarantees a safe and reliable check.

Interactive and batch comparison

The model comparison can be carried out interactively in CATIA or LiteBox3D or for a process integration also in batch.

Detailed and flexible reports

The user receives a detailed XML report of all changes including graphical representations. The reports can also be customized using form templates.

Simply compare models

The following document comparisons are currently possible:

xCompare V5 / V5

With xCompare V5 / V5, the user can check interactively or in batch whether models – individual parts, assemblies and drawings – have been changed compared to another model. Based on the feature-based comparison, xCompare not only reports the geometric differences, but also shows the user the changed CATIA element. Changes that a development partner has made can be seen quickly. xCompare is fully integrated in CATIA V5 and available for all CATIA V5 platforms.

The following videos are examples of how individual parts or drawings can be compared using xCompare V5 / V5:

xCompare V5 / SMG

xCompare V5 / SMG checks the conversion process from CATIA V5 to SMG (CATIA Composer / 3DVIA Composer), which is of great importance for downstream processes and long-term archiving. The CATIA V5 model is compared to the SMG model based on various criteria. xCompare uses the respective models directly and reads the properties and geometries to be compared without first converting them into a program-specific format. This guarantees a safe and reliable check. xCompare V5 / SMG is fully integrated in CATIA.

xCompare V5 / JT

In many industries, CATIA data is transformed into various neutral formats to provide downstream processes with the right data. In the automotive industry in particular, CATIA data is converted to JT format. For some downstream processes, it is important to ensure that the conversion does not change the two data. Unacceptable differences must be found before they flow into the downstream process.

xCompare V5 / JT is an application for comparing CATIA V5 and JT data. In the first place, the geometric data are compared – possible deviations

The results are shown graphically. V5 B-Rep can be compared with the JT B-Rep (JT or XT B-Rep), V5 B-Rep with individual JT LODs (Level of Detail) and V5 CGR data with JT LODs. The results are displayed within V5 and graphically represent the differences in the geometry. Of course, the results are saved in XML reports for further documentation. The xCompare V5 / JT solution directly checks the original data without prior conversion – the data remains unchanged.

xCompare JT / JT

With xCompare JT / JT, the user can interactively check two JT individual parts or assemblies (PLMXML) within the LiteBox3D or in batch. In a configuration stored by the administrator or created by the user, the criteria used to compare the models are stored. In addition to the geometric comparison of the B-REP and LOD, the finding of structural changes and metadata is also included.
