    Editing an Existing Sketch

    • Select "Sketch" on the Sketch Toolbar or "Insert > Sketch"
    • Right-click the sketch in the FeatureManager design tree or entity in the graphics area and select "Edit Sketch"

    Part Modeling

    • A 3D part is the basic building block of parametric modeling software
    • Features are individual shapes that make up a part
    • Features can have parent and child relationships

    Reference Geometry

    • Defines the shape or form of a surface or solid
    • Includes Planes, Axes, Coordinate Systems, and Points

    Reference Planes

    • Planes can be created in a part or assembly document
    • Used for sketching, section views, draft features, etc.
    • Create a reference plane by selecting "Plane" or "Insert > Reference Geometry > Plane"
    • Set a First, Second and Third Reference to fully define the plane

    Reference Points

    • Reference points can be created at intersections of:
      • Axis and Plane
      • Axis and Surface
      • Two Axes

    Reference Axes

    • Used in sketch geometry and circular patterns
    • Created with "Axis" on the Reference Geometry toolbar or "Insert > Reference Geometry > Axis"
    • Select the axis type and required entities
    • View the new axis with "View > Hide/Show > Axes"

    Coordinate Systems

    • Define a coordinate system for a part or assembly
    • Used with Measure and Mass Properties tools, exporting, and assembly mates
    • Create a coordinate system with "Coordinate System" or "Insert > Reference Geometry > Coordinate System"
    • Select an Origin, Axis Direction Reference, and reverse direction if needed

    Features Toolbar

    • Provides tools for creating model features
    • Features can be customized by adding and removing icons

    Extrude

    • Extends a sketched profile in one or two directions as either a thin feature or a solid feature
    • Can add or remove material
    • Create an Extruded Boss/Base, Cut, or Surface by selection the appropriate tool from the Features toolbar or Insert menu

    Revolve

    • Adds or removes material by revolving one or more profiles around a centerline
    • Create a Revolved Boss/Base, Cut, or Surface by using the appropriate tool from the Features Toolbar or Insert Menu

    Revolve Feature

    • Revolve feature creates solid or surface geometry by rotating a profile (sketch) around an axis.
    • The revolved feature can be a base, boss, cut, or surface.
    • Revolve feature can use 'Direction 1' and 'Direction 2' choices, which define the direction the feature is revolved.
    • Direction 1 revolves in the same direction as the specified sketch plane normal
    • Direction 2 revolves in the opposite direction to the specified sketch plane normal
    • The feature is revolved around the specified axis, which can be created as a line or edge.

    Sweep Feature

    • The sweep feature creates a feature by moving a profile (sketch) along a path.
    • The swept feature can be a base, boss, cut, or surface.
    • The profile can be closed or open and can be a sketch, existing model edges, or curves.
    • The path can be closed or open and can be a sketch, existing model edges, or curves.
    • The start point of the path must lie on the plane of the profile.

    Helix and Spiral Feature

    • Helix and spiral features create a helix or spiral curve on a part.
    • These curves are often used as a path (guide curve) for creating other features like swept or lofted features.
    • Helix or spiral features can be defined using various methods:
      • Constant pitch
      • Height and revolution
      • Height and pitch
      • Spiral
    • Variable pitch helixes allow for defining regions with different parameters like height, diameter, and pitch.
    • Spiral features create an inward spiral, and the direction of the turns can be clockwise or counterclockwise.

    Loft Feature

    • Lofts create a feature by making transitions between profiles.
    • Lofts can be a base, boss, cut, or surface.
    • Lofts are created using two or more profiles, and only the first, last, or first and last profiles can be points.
    • All sketch entities (profiles, guide curves, etc.) can be contained in a single 3D sketch.

    Dome Feature

    • Dome feature creates one or more dome features simultaneously on the same model.
    • The dome can be circular, elliptical, or continuous.
    • You can control the dome by selecting a sketch that contains points to constrain the shape.
    • The dome can be extruded in a direction other than normal to the face.

    Shell Feature

    • The shell tool hollows out a part, leaving open the faces you select and creating thin-walled features on the remaining faces.
    • Shell features allow for defining a uniform thickness for the removed material.
    • Shell features can be created with multiple thicknesses.

    Draft Feature

    • Draft feature tapers selected faces in the model using a specified angle.
    • Draft is used to make molded parts easier to remove from the mold.
    • Draft can be applied to solid and surface models.
    • Draft can be applied as part of extruded base, boss, or cut features.

    Rib Feature

    • Rib feature is a special extruded feature created from open or closed sketched contours.
    • Ribs add material of a specified thickness in a specified direction between the contour and an existing part.
    • Rib features can be created using single or multiple sketches.
    • Rib features can have draft applied to them.

    Wrap Feature

    • The wrap feature allows you to wrap a sketch onto a planar or non-planar face.
    • The wrap feature can be defined using two methods:
      • Analytical
      • Spline surface
    • Wrap feature allows you to create three types of features:
      • Emboss: Creates a raised feature.
      • Deboss: Creates an indented feature.
      • Scribe: Creates an imprint of the sketch contours on the face.

    Intersect Feature

    • Intersect tool lets you intersect solids, surfaces, and planes to modify existing geometry or create new geometry.
    • Intersecting can help remove material from a model, create geometry from an enclosed cavity, or merge solids.

    Hole Features

    • Two methods for creating holes:
      • Simple Hole: Quickly create a hole without additional parameters.
      • Hole Wizard: Creates more complex holes with additional features like Counterbore or Countersunk.
    • The Advanced Hole tool allows defining holes from the near and far side faces of a model.
    • Simple hole can be positioned and dimensioned after creation.

    Hole Wizard Feature

    • Hole Wizard feature allows for creating customized holes of various hole types:
      • Counterbore: Defines a counterbore with specified diameter and depth.
      • Countersunk: Defines a countersink with specified diameter, depth, and angle.
      • Hole: Defines a standard hole with a specified diameter and depth.
      • Straight Tap: Defines a threaded hole with a straight thread.
      • Tapered Tap: Defines a threaded hole with a tapered thread.
      • Legacy: Defines holes using legacy parameters.

    Thread Feature

    • Thread feature creates helical thread on cylindrical edges or faces.
    • Thread feature can be created using two methods:
      • Cut thread: Creates a thread by removing material.
      • Extrude thread: Creates a thread by adding material.
    • Thread can be right-handed or left-handed.
    • Thread features allow for multiple start threads.
    • You can align thread trim to the start or end face.
