Shape Generation Scripts

Shape Generation Scripts

Scripts in this category generate geometry programmatically from user-defined parameters. They require an open CATPart document unless stated otherwise.

Script	Description
Custom Coordinate Airfoil Generator	Generates a GSD point set and spline from user-supplied X Y (or X Y Z) coordinates loaded from a file or pasted into the dialog
Ellipse Generator	Generates an ellipse as a point set and closed GSD spline from semi-major and semi-minor axes
Hole Size Test Plate Generator	Generates a rectangular test plate with a grid of through-holes of incrementally increasing diameter
Involute Gear Generator	Generates a fully parametric involute spur gear
NACA 4 Digit Airfoil Generator	Generates a NACA 4-digit series airfoil as a GSD point set and closed spline at a user-defined chord length and resolution
NACA 5 Digit Airfoil Generator	Generates a NACA 5-digit series airfoil as a GSD point set and closed spline at a user-defined chord length and resolution
Plot 2D Function	Plots y = f(x) as a GSD point set and spline from a user-entered math expression over a specified X range
Plot 3D Parametric Curve	Plots a 3D parametric curve x(t), y(t), z(t) as a GSD point set and spline from user-entered expressions
Regular Polygon Generator	Generates a regular polygon as vertices, edges, and a joined wire; supports custom plane and centre point selection
Sine Wave Curve Generator	Generates a sine wave curve as a point set and GSD spline from amplitude, period, phase, and X range
Spring Generator	Generates a parametric helical spring solid from wire diameter, coil diameter, free length, and coil count
