PyCATIA module

Create a simple sketch in PyCATIA by selecting the part body, setting the xy plane as sketch support, adding a four-point square, and updating the document.

Create a new document, set the part body as the work object, and draw a square and circle in the xy plane, then a spline with a predefined tuple.

Apply sketch constraints in PyCATIA by selecting constraint types for one to three elements, using a common constraint list, and constraining circles and points to achieve full constraint.

Create and use construction elements in sketches, including a circle and a construction line, then mirror a circle with symmetry constraints to achieve a fully constrained sketch.

Create 3d points, lines, and planes with the generative design workbench. Store elements in construction elements set and define planes by offset, three points, or a line and a point.

Create a polyline in PyCATIA by starting a new document with the factory, adding an empty polyline, and inserting points in order inside the polyline.

Create a spline by using the hybrid shape factory, adding four points that automatically determine order, append the spline to construction elements, and update the document.

Learn to create circles and arcs in PyCATIA's Generative Design Workbench by using center-radius-angle and three-point methods, and control circle limits to form full circles or arcs.

Create a new Catia document, set up construction elements and points, then build spirals and helices by specifying propagation axis, spiral type, center point, starting radius, pitch, and rotation direction.

Create and link parameters in a PyCATIA part, defining length, angle, and a point to control the hybrid shapes and the circle's position via formulas.

Organize parameters with nested parameter sets and subsets, reference them with the item function, and use formulas to multiply a base length by two at each depth, updating parameter tree.

Create a path by extruding a sketch perpendicularly with the shape factory, setting orientation, offset, and distance; then create a pocket from a second sketch using the last limit setting.

Learn to obtain vertex, edge, and surface references via the user interface and selection filter, then use them to perform operations like creating sketches and points on surfaces.

Project 3d solids into sketches by projecting a cube and a cylinder onto a plane, using the projections and reference commands. Silhouette edges require a plane that intersects the solid.

Master shaft and group commands in PyCATIA by revolving sketches around the x axis to add or remove material, creating a disc with a hole and trimming the perimeter.

Apply fillet and chamfer operations in PyCATIA to modify solid edges. Learn to select edges, apply a constant-radius fillet via the shape factory, and add multi-edge chamfers with propagation modes.

Learn to use the shell command in PyCATIA to create hollow bodies, select faces with the manual filter, and set internal and external thickness, including two-phase shells for multiple surfaces.

learn to create ribs by extruding a square along a guiding spline and to cut slots by removing material from a second sketch, using the hybrid shape factory.

Explore common body transformations in PyCATIA, using the shape factory, including mirror, rotation around a revolution axis, and scaling in the z direction, with a note on translate.

Create rectangular and circular patterns in PyCATIA by copying a body along x and y directions or radially, using shapes factory commands with specified copies, spacing, and optional single-direction patterns.

Learn to generate a surface by extruding a curve with the extrude command in PyCATIA. Use a square polyline, the hybrid shape factory, and set direction and symmetry.

Use revolve to create a surface by revolving a spline about the z axis, setting axis direction with hybrid shape factory and specifying angles, then append to a hybrid model.

Explore the PyCATIA split command to split a surface with another using the reshape factory’s hybrid split, pick the side to keep, and optionally display the intersection line.

trim a surface with another using the hybrid trim in the hybrid shape factory, specify the first and second curves and orientations, then adjust the orientation to create different results.

Create a sphere and a cylinder in Picatta using the Hybrid Shape and High Ridge factories, specifying sphere center, axis, radius, angles, and cylinder center, radius, lengths, extrusion direction.

Use the hybrid shape factory to project a sketch curve onto a surface, defaulting to normal projection with an optional direction control (for example 010 along the y axis).

Create a curve from the intersection of two surfaces using the hybrid shape factory's add new intersection command. Specify two curves and run the operation to obtain the intersection curve.

demonstrates using shape fillet and edge fillet with a hybrid shape factory to create a bitangent round corner between two surfaces, with adjustable orientation and trim options.

Learn to create a multi section surface through multiple curves using the hybrid shape factory and loft, with optional guide curves to control tangency and smoothness across profiles.

Sweep a closed square polyline along a spline curve to generate a surface, inputting the polyline and curve via the hybrid shape factory's add new sweep explicit.

Discretize a curve and extract its coordinates by iterating a ratio from 0 to 1 on a spline, updating the document, and retrieving coordinates with the get coordinates function.

Create a CFD domain by building cube arrays, subtracting their volume from the fluid domain via a boolean operation, and export for parametric studies and optimization.

Access and modify parameters in a non-designed cad part to perform a parametric study, adjusting edge fillet radius and a sketch circle, then run an optimization loop and generate files.

In the PyCATIA module, learn CATIA manifold design by creating a parametric exhaust manifold with sketches, extrusions, fillets, patterns, and sweeps, then apply shells for wall thickness.

design a wind turbine blade in Catia by importing profile coordinates, generating guide curves, lofting a multi-section surface into a solid, and using adaptive blend to join blade and hub.

Generate a simple wing structure with a winglet by defining a NACA profile, setting span and sweep, and detailing ribs, holes, and lofted geometry for Catia.

Build an axisymmetric car wheel rim by sketching a rim section, revolving 22.5 degrees, and using circular patterns, cuts, and mirrored solids to form the full rim with bolt holes.

Learn to generate a parametric NACA airfoil in CATIA using a direct mathematical formulation, implementing thickness, camber, and twist in Python and CATIA KTM to produce a smooth, scalable surface.

Develop a fully parameterized blade in CATIA using NACA airfoil profiles, hub blending, twists and chords, and guide curves to loft blade surfaces and pattern multiple blades.
