See the list of PLM Acronyms here.
See the list of SmarTeam Acronyms here.
During the transition period to the PLM, access to CATIA through the PLM is not freely available to all users. You must be granted access to the PLM-CATIA connector.
If you do not have the connector installed, or it is an out of date version, you will receive the following message when attempting to launch CATIA through the button on the PLM dashboard. This will remind you which applications must be installed and a link to CMF. There is also a link to documentation explaining the prerequisites required before running this application.
If CATIA is not installed the launch button will be greyed out.
To request access to the connector please contact plm-support@cern.ch and also state your PC name. Prior to granting you access, we would ask for you to complete the SmarTeam to PLM training, please see the link here.
However, if you need immediate access to prevent a project from becoming blocked, please sign up to the next available training and contact us explaining your situation. If deemed necessary and suitable we will grant early access to allow work to be continued.
There are three main different CATIA configurations that can be selected from the drop down in the CATIA launcher menu, small, large and equipment systems. Below details the main differences in their set up:
- Small – Cache is deactivated so all parts are opened in design mode, resulting in them taking longer to load. The 3D Tessellation accuracy is higher than in the large setting. Assembly updates are automatic.
- Large – Uses cache so parts are opened in visualisation mode. To edit, or view at a greater accuracy, the parts must be manually activated into design mode. The 3D Tessellation accuracy is lower than in the large setting. Assembly updates are manual.
- Equipment systems – The settings are primarily the same as the large except the assembly updates are automatic. There is also a difference in the available workbenches. Equipment systems contains two extra workbenches; HVAC design and piping design. However, it also has one removed, raceway design (an electrical cabling discipline).
CATIA customised settings, such as shortcuts, can be saved in the PLM dashboard to be used when CATIA is reopened. This is also true for PWB setting changed in the options toolbar.
To save new customised settings, close the CATIA session in which the changes were made. Press the cog icon on the CATIA launcher to open the CATIA configurations window.
Enter a name for the new settings configuration. It will be saved and stored under one of the three main configurations that the CATIA session was originally opened under, and the settings were changed in.
Note the setting name may only contain alphanumeric characters and spaces, and be a maximum length of 64 characters. Configuration settings can also be deleted from this window by pressing the bin button next to them.

A CAD document is made up of data, metadata. Some of this comes from CATIA such as the geometry, mass and material. Some of it comes from the PLM, Design code and RPG.
Two pieces of metadata can be changed in both the PLM and CATIA, the CAD definition and description. These two properties are mapped in both directions so can be modified in either platform and the data will be updated in the other. However, its important to understand when this information is transferred, so as not to loose any data.
- Data is pushed from the PLM to CATIA when a document is first opened.
- Data is pushed from CATIA to the PLM when a document is saved.
Why this is important?
If you have a document open in CATIA and change either the CAD definition or description in the PLM platform, these updates will not be pushed to the already open document in CATIA. The CATIA data will not be updated. Therefore, if the CAD document is subsequently saved in CATIA, the 'outdated' CATIA data will be pushed to the PLM overwriting the previous change.
Therefore, please do not change a documents metadata in the PLM if the document is already open in CATIA. Please do the changes in CATIA.
Note: If a document is modified in the PLM whilst it is open in CAD, when the CATIA tree is refreshed the definition will be updated because this displays data directly from the PLM connector. However, the CATIA data is not updated. This can be verified by viewing the data via right click > properties.
The order of the BOM is determined by the CATIA tree. The BOM is built based on the positions and quantities in the CATIA tree, using a top-down approach.
Please note:
- Only CAD Documents identified as 'Master' 'Representation type' are automatically included in the BOM. See the full FAQ to understand how to manually add documents of alternative 'representation types'.
- The first instance of a reference found in the tree structure is what determines its position in the BOM.
There are manual ways to override the CATIA positions & quantities, for further information on this see the FAQ below. However, you can also simply reorder the CATIA tree to order parts in the BOM as you desire. Use the 'Graph tree Reordering' function in CATIA to easily move the parts around.
The third button in the window can be used to move the part quickly next to any other, by selecting one in the list. Note when moving a part down from its current position, it will be placed under the document you select. When moving up, it will be placed above.
A BOM can be projected onto a drawing using the Title Block Editor (TBE).
When you click on the Title Block Editor icon in CATIA V5, 
it will open in a new window. The BOM can be found in the second tab, called “Bill of Materials”.
Check the “Bill of Materials” box to add the BOM to the title block of the drawing. Then click on “Generate & Save” to add the BOM and the title block to the drawing.

The first part of this FAQ will show you a quick method of saving a CAD document without dependencies, like a CATPart. The second, more detailed, section will describe how to save a structure where the files are linked to each other and will explore the different options available to you from the connector. The final part will explain you how to duplicate a CAD structure.

The PLM uses an automatic engineering BOM (EBOM). This means every time you save an assembly the BOM will be created/updated on each 'claimed' or 'new' assembly node.
The BOM uses the positions and quantities of the instances in the CATIA tree, using a top-down approach.
Please note:
- Only CAD Documents identified as 'Master' 'Representation type' are automatically included in the BOM. See the full FAQ to understand how to manually add documents of alternative 'representation types'.
- The first instance of a reference found in the tree structure is what determines its position in the BOM.
- There are manual ways to override the CATIA positions & quantities, see the FAQ below.
You can also trigger a forced manual BOM synchronisation at any time from the “More” menu of the CAD Document profile card in the PLM platform.
If you are new to CATIA/PLM, the document at the bottom will introduce and explain the basic concepts to help you get started.
Please follow the necessary training before using the PLM. You can access the training and learning path here, this will help you identify what training is necessary for you depending on your previous experience and knowledge.
Training on the CATIA-PLM connector (PWB) is a prerequisite to being granted access to CATIA via the PLM. Once you have completed the training please contact the PLM support team with your computer name, so you can be given access. Prior to having access rights, you will receive an error message when attempting to launch CATIA, and you will not be able to view the connector package in CMF.

The CGR and Approximate format contains only the graphical representation of the geometry. These options allows you to choose different appearances of the linework of your Drawing.
The CGR files are facetted models for visualisation that can't be edited but they can be used for interference checks. It can also be used as a light representation of a native model that is too heavy for the computer to load, so it is helpful with big assemblies.
The Approximate mode reduces memory consumption and it consumes even less memory and is faster than CGR.
To edit this properties go to the Drawing and right-click on the frame, then select "Properties". Scroll down in the new window and look for the section "Generation Mode". Below you can find the "View generation mode" and from there you can choose CGR or Approximate view.

- Go to Tools ➞ Option ➞ Infrastructure ➞ Product Structure ➞ Nodes Customization.
- Tick the "Customized display" (if not already ticked) and open the "Configure customized display" window using the "Configure...".
- In the new window add "Definition" ("#DF") to your product.
- Close. The CAD Definition should be changed in your CATIA tree.
Note 1: if in the same CATIA session, you visualize another product structure from the PLM, the Definition will appear twice.
Note 2: if you want to keep this setting by default for your future CATIA sessions, you need to save your settings.
In CATIA, from the connector toolbar, clicking on the Query icon, you will be able to access the PDM Query dialog and to search for any CAD document previously uploaded to the PLM platform. Once the searched CAD Document has been found and selected, a double-click will open it in CATIA.
Note that the double-click corresponds to an Open as Saved.
See the 'Opening' subgroup for related information

For CAD designers, it is also possible to report an issue from the PLM desktop application.
This way, the request created in Service Now will already contain some useful information for the PLM Support Team (PC name, date and time when the applications were launched, CATIA active document reference …).
This is the way to report the problems to be privileged.
The CATIA connector installation is performed via the CERN CMF installation manager, through the icon as shown in the image below.
Once your computer is added in the NSC (to complete this process, the admin or the main user of the computer must accept a request sent via email), then, you will be able to install the CATIA connector via CMF.
The main purpose of the toolbox is to design a multi-layer's coil or magnet spacers defined by points coordinates stored in a text file. You can also use this tool to estimate the quality and conformity of generated parts by searching intersection between correspondent coils and spacers. Tool can be used to check the quality of generated spacers by finding distance between the points from text file and the used ones for the design. Tool can be used for exporting constructed data in STEP format.
If you have more questions about this, please check the document under.
To import you need the "Part Template" tool. This can create some 3D points in Catia V5 from their coordinates stored in one Excel file. The created points can be automatically renamed if the name information is available in the Excel file. An optional feature allows building straight lines between every point.
If you want to know details, please check the document below.
The tool that you have to use is a "Power Copy". To use it, a Part must be activated. If you want to know more details, please open the document which is under.
This tool generates a CATPart from a CATProduct, using the "Generate CATPart from Product..." command. Then the tool scans the original Product to search for the materials associated to the parts. It is also possible to run this macro from an existing CATPart generated previously, if the corresponding Product is also opened in Catia V5 to add the material and definition parameters.
If you want to know more about this tool and how to generate this process, please follow the document below.
The "Optimization" workbench is available in Catia V5. It is possible to use it to solve more or less complex problems. You will find in the document below some simple examples in which some optimizations are used and some information on how to put them in place.
The CATIA Knowledgeware regroup a lot of functions: rules, optimizations, templates... that allow you to create generative tools or parametric constructions. Most of the common functionalities we can use in CATIA are contained in "Product Synthesis" solutions.
To start, go to the "Mechanical Design" and then to the "Generative Sheetmetal Design" workbench. Click on the icon and specify the correct parameters of the sheet that you are going to work with: "Thickness", "Default Bend Radius" and "Bend Extremities". The "Sheet Metal Parameters" feature should be added in the specification tree.
If you want to see step by step how to do it, please follow the document below.
The following document has an explanation how to do this step by step. Please check it if you want to know more.
The "Surface Curvature Analysis" is used to find the curvature of the surface or the face of a solid. You can perform analysis in "Part Design" as well as in "Generative Shape Design". If you want to see how the procedure should look like, please open the document below.
Split is an operation where one element is cut by another element.
Trim is an operation in which two elements cut each other mutually.
If you want to see more details and differences between these two functions, please check the document below.
To get the surface from land contour lines you need to proceed from the isolation of the relevant geometry, then the improvement of the quality of the geometry and then the generation and extraction of 3D points. Then you should transform the 3D points into the cloud of points, generate a mesh and then finally auto create a surface feature. If you want to know more details about it, please follow the link below with explanation.
Distance analysis tool could be used to measure distance between surfaces which are very close to each other. The distance is computed in several points so as result we will get the distance distribution between chosen surfaces. You can find "Distance Analysis" tool in "Shape Analysis" toolbar which is available in “FreeStyle” workbench. To find it, follow the instructions on the document below.
You can now create planes between two existing planes at once.
Follow the instruction to do this:
- Click on the "Replication" toolbar.
- Find the icon "Planes Between".
- When the dialog box appears, select two planes between which the new planes must be created (it cannot be parallel).
- Indicate the number of planes.
- Click "Preview" to see the plane created.
- Click "OK".
- Planes are added to the tree specifications.
For more details, please check the document below.
For objects with features that are symmetrical in the thickness direction, a middle surface can be created using functions from the Generative Shape Design (GSD) workbench. There are several options on how this can be done.
In the following document you can find three scenarios that a user can basically come across:
- All of the object’s relevant features are symmetrical in the thickness direction.
- Some of the object’s relevant features are asymmetrical in the thickness direction.
- It is possible to create the solid from the surface rather than the other way around.
To know it better, please check the methodology in the link.
A 3D curve can be created in space or lie on a geometrical element, or both. When the curve lies on a geometrical element, associativity can be kept. It is also possible to edit, delete or add points when creating the curve, or after. A 3D curve is a very fast and flexible tool which is really different from a "Spline".
- route electrical wires,
- work with Bezier Nurbs,
- create a guide curve for a sweep or a rib.
From the following document, you will learn new possibilities about 3D curve from "FreeStyle" workbench.
The 3D curve function is available in the Freestyle workbench. With the 3D curve function, it is possible to create associative curves in which you can add or remove points during the creation of the curve and also later.
If you want to know more details, when to use it or how to modify it, please check the document below.

If you want to learn how to create a run and place a "Pipping Part", please study the document below which inside you can find an example how to design it.
Often enough, there is a need to switch between a 2D opened in CATIA to its corresponding 3D. In order to facilitate and quicken this task, it is possible to open the 3D directly from the 2D. To know more about this procedure, please check the document below.
The document below is only applicable to the Integration team.
For the other users, if an A0 sheet is too small, please follow this link: CLICK.
Due to a bug in CATIA V5 it is impossible for users to place multiple orthogonal leaders.
The link below explains a workaround which enables the use of orthogonal leaders. It shows as example the creation of orthogonal leaders on the Geometrical Tolerances.
Soon CDD will be able to store drawings with several sheets but today it is still not possible. If you have a design that doesn’t fit only in one sheet of the drawing, and you need to upload all the sheets to CDD we have the following procedure.
In order to learn more about this, please consult the following document.
A drawing can be called “too large” when the native file size is a number with more than 6 digits. Unfortunately, there is not a perfect solution but in the document below there are different methods and options that depending on each case can be used to generate a lighter drawing. Please follow the link to understand it better.
In some cases, you can use in the "Tools Palette" and it can be recognized during the creation of the dimensions. It is always possible to add these points manually and after using them, create the dimensions. The blue lines and the intersection points are not visible when the document is outside CATIA (printed or in CDD).
If you want to understand more details and how to represent the prolongation lines to the intersection point, please open the following document.
- Select one or more holes in the drawing.
- Click "Hole Dimension Table" in the dimensioning toolbar.
- The Axis System and Table Parameters should be displayed.
To know more about the dialog box and what to type or select, please check the following document.
In CATIA it is not possible to add the symbol envelope direct to a diameter.
Here there is a workaround to add it if the dimension:
- is not a diameter or a radius
Properties ➞ Dimension Texts ➞ Main Value ➞ click on the symbol - is a diameter or a radius
Properties ➞ Dimension Texts ➞ Prefix Suffix ➞ choose the group of symbols (first icon) ➞ Main Value ➞ click on the symbol
If you want to see step by step how to do it, please follow the instruction which is in the document below.
The drawing standard is stored in the drawing upon the creation, this standard 'copy' is kept independently this means it will not automatically update when the standard settings of CATIA change.
There is a procedure step by step how to do it:
- Open and Check-out the Drawing.
- Go to the File ➞ Page Setup.
- In Page Setup window select the standard of the drawing like ISO_CERN.
- Push the "Update" button.
- Update the elements which changed in the standard.
If you want to know more details about this procedure, please check the document which is under.
You can create a section view using a 3D profile or a plane in the 3D, as sectioning element. Using a 3D element to define a section view makes possible to constrain this element with the geometry of the part. The profile section will automatically be kept up to date if the 3D geometry changes. Check the document below if you need more information how to create it.
The colors of dimensions are controlled by the "Analysis display mode". Select this option to display dimensions using different colors according to their status (not-up-to-date, isolated, fake, etc.).
In the document below you can find all configurations of colors.
Due to a Catia limitation, the "3D Clipping View" function from the "Drafting" workbench is not compatible with the "Do not cut in section views" options, which are in the "Drafting" tabs of the 3D properties or in the "Overload Properties" on the 2D view.
If you want to study alternatives, please check the document below with explanations.
- Open the "Link Modification" window from the view.
- Select the scene in the 3D.
- Switch the scene in the "Pointed elements".
- Validate and update the view.
If you want to see step by step how to do it, please click on the link which is under.
On a drawing, it is possible to display extra digits on the dimensions for specific purposes (e.g.: to highlight that a dimension has not been rounded on the drawing).
