CATIA 3D Drafting and Annotation (TDA)

If you are using 2D drawings to capture tolerancing and annotations, they must be synchronized with 3D modifications to ensure the manufacturing design is consistent and up-to-date throughout, so that your products are correctly manufactured. However, the synchronization process can be time consuming and error-prone. It also makes it impossible to use 3D tolerance analysis further down the road. Based upon 3D definition, CATIA 3D Drafting and Annotations guarantees the consistency between 3D design and 2D tolerances and annotations. The 2D layout can be directly created in 3D to define the product and to capture key manufacturing knowledge. In addition, you can create a 3D product from a 2D schematic. Then it’s possible to move on and generate the assembly drawing to make the product definition directly re-usable for manufacturing planners and propagate downstream systems.


  • This product offers a new efficient user interface that helps 2D-based designers reach a 3D process methodology and enables 3D-based designers to manage an early 2D layout for their future 3D design. You can also position multiple views in a 3D environment. Plus you can add 2D geometry in the views and capture design intent by benefiting from all normalized dimensions, annotations, and dress-up capabilities. Moreover, advanced print capabilities ease the review of the conceptual design phase and improve productivity. You will experience smooth interactions between 2D and 3D design by linking the 3D geometry to the 2D geometry and as well as edit within a consistent, transparent, display of 3D.
  • You can benefit from powerful tools to export 2D geometry as profiles and planes to quickly create associative 3D geometry. Dimensioning and tolerancing annotation data can be added, with respect to norms, from the preliminary design phase, and therefore don’t have to be recreated in generated drawings for delivering technical documents.
  • To help you improve productivity, View Filters enable the easy design of 3D models in a 2D process context by simplifying the visualization of the design view. Filters are defined at the 2D Layout level and are referenced, on demand, by each view. You can also benefit from advanced print management, during conceptual design phases.
  • Thanks to the 2D/3D design workbench, you can create and manipulate 2D Layout data within 3D models.
