In this CAD tutorial we'll use the features:Ā
š§± Extrude
ExtrudeĀ is the most fundamental commandĀ for turning a 2D sketch into a 3D solid. It works by extending a sketch profile in a straight line, either to add materialĀ (a "join" operation) or to remove materialĀ (a "cut" operation).
š Fillet & Hole
These commands are used to modify edges and create standardized features.
Fillet: This command creates a smooth, rounded edgeĀ on a part by adding or removing material. You specify a radius for the rounded edge, and it's used for aesthetics and to prevent stress concentrations.
Hole: This is a specialized toolĀ for creating different types of cylindrical cutsĀ in a part. It is much faster and more accurate than a simple extruded cut for creating standardized holes.
š© Thread
The ThreadĀ command is a specialized feature used to apply cylindrical threadsĀ (internal or external) to existing holes or shafts. You can use it in conjunction with the HoleĀ command to specify a tapped hole. The thread command typically applies a visual representation and specifies the technical data of the thread (like size and pitch) without modeling the complex physical geometry of the threads unless specifically chosen.
All dimensions are in mm/g/s/ISOĀ Ā
3D Sketch

Exercise 32 - 3D practice drawing for all CAD software ( AutoCAD, SolidWorks, 3DS Max, Autodesk Inventor, Fusion 360, CATIA, Creo Parametric, SolidEdge etc.)
