CATIA Mechanical Surface Design provides a unique and powerful spec-driven modeling approach for the creation of high-end mechanical shapes, as well as intuitive manipulation of free form surfaces. This standard solution for high quality surface modeling promotes efficient, concurrent engineering between styling and shape design so that the product design workflow is optimized.
A comprehensive set of features is provided. These include wireframe elements (point, line, plane, circle, spline, parallel curves, corner on plane, connect 3D, spiral, helix, conics, etc.) and also include standard and advanced surface features (extrude, revolute, swept surfaces). Both standard and advanced combinations of elements can be used in associative transformation, including symmetry, scaling, translation, affinity, extrapolation and fillet.
The wireframes and surfaces can be designed using the part or assembly context. Design in context allows concurrent work with user control of associativity. Thanks to the powerful associativity mechanism, any required design change is easily controlled and rapidly propagated at any time for easy shape design optimization.
A suite of powerful modifying features is available and can be applied on curves and surfaces (intersection, projection, offset - including variable and rough, and many kinds of fillets and chamfers, etc.). Users are provided with high productivity help such as repeat options and quick multi-creation mechanisms.
The CATIA geometrical modeler is able to manage operations on curves and surfaces even those with small geometrical gaps (max = 0.1 mm). The smoothing capabilities and the tolerant lay down options make designers able to perform their usual tasks and continue a normal work flow, while compensating the gaps and achieving high-end quality surfaces
The native integration with CATIA Knowledgeware products brings the user the best in class tools to create complex and smart surfaces faster. Also, CATIA Mechanical Surface Design enables the reuse of the same surface geometry in multiple instances, allowing concurrent engineering to take place. It can reuse a surface geometry linked to an existing surface providing master model design methodologies
Quickly and easily unfolds ruled and non-ruled surfaces and develops curves on revolution surfaces. It allows flattening ruled and non-ruled surfaces such as cylinders, continuous point blend, and sweeping segment. The user is then able to verify the mathematical surface of a shape. Once the surface is flat, it is easier to manage bulk calculations, raw material cost calculation, and manufacturability calculation. Design engineers, both non-surface specialists and advanced-shape designers, can define an associative flattened pattern from their 3D models for manufacturing from flat sheets of raw materials.
Unifies all types of free-form curves and surfaces in a single math-free representation. It provides surface-based tools to help designers create styled shapes and surfaces, enabling even casual users to easily smooth and trim curves and surfaces. Designers can create flawless, styled shapes from scratch, in order to model three-dimensional free-form curves and surfaces. The system can blend and extrude curves, fill, and blend or match surfaces.
Provides immediate visual quality control through extensive and associative real-time curve and surface diagnosis tools. These tools include: Environment mapping, Pixel isophote mapping, Porcupine analysis of curvature, Dynamic cutting plane, Connection checker, Surface/element distance analyzer, Draft mapping analysis, Curvature mapping analysis.
