1 3D Modeling Features and Modeling Strategy Professor Name Course Name

2 Copyright Planchard D Feature Modeling The first feature you create in a part document is the base.base This feature is the basis on which you create the other features. Keep the Base feature simple! The base feature (always adds material) can be an extrusion, a revolve, a sweep, a loft, thickening of a surface, or a sheet metal flange. Features either add, subtract or have no effect on the (material) of the part.

3 Copyright Planchard D Feature Modeling - Feature Select the correct base Feature. This feature is the basis on which you create the other features. The following are some of the features you can use to make parts in SolidWorks.

4 Copyright Planchard D Feature Modeling - Feature (Cont:) Boss/Base Extrude - Extrude creates a feature by extruding a 3D object from a 2D sketch, essentially adding the third dimension. An extrusion can be a base (in which case it always adds material), a boss (which adds material, often on another extrusion), or a cut (which removes material).Boss/Base Extrude

5 Copyright Planchard D Feature Modeling - Feature (Cont:) Think intelligent design - design intent. Select the proper End Condition: –Blind –Up To Vertex –Up To Surface –Offset From Surface –Up to Body –Mid Plane

6 Copyright Planchard D Feature Modeling - Feature (Cont:) Extrude - Thin – Use the Thin Feature options to control the extrude thickness (not the Depth ). A Thin Feature base can be used as a basis for a sheet metal part.Extrude - Thin Think intelligent design - design intent. Select the proper End Condition: –Blind –Up To Vertex –Up To Surface –Offset From Surface –Up to Body –Mid Plane

7 Copyright Planchard D Feature Modeling - Feature (Cont:) Revolve - Adds material. Revolve creates a feature that adds or removes material by revolving one or more sketch profiles around a centerline.Revolve The feature can be either a solid, a thin feature, or a surface. Revolved Base Feature. Note: The location of the Origin! What is the sketch procedure for this model?

8 Copyright Planchard D Feature Modeling - Feature (Cont:) Loft - Adds material. Loft creates a feature by making transitions between profiles (Planes). A loft can be a base, boss, cut, or surface.Loft

9 Copyright Planchard D Feature Modeling - Feature (Cont:) Sweep - Adds material. Sweep creates a base, boss, cut, or surface by moving a profile (section) along a path.Sweep Think of a spring…, a paper clip…., etc,

10 Copyright Planchard D Feature Modeling - Feature (Cont:) Rib - Adds material. Adds thickness to the selected side of the sketch. Can be an open profile. Use Ribs to improve structural integrity.Rib

11 Copyright Planchard D Feature Modeling - Feature (Cont:) Dome - Adds or removes material. You can create one or more dome features simultaneously on the same model.Dome

12 Copyright Planchard D Feature Modeling - Feature (Cont:) Revolved Surface Feature. Adds material. Note: The location of the Origin! Spline Revolve profile about an axis Origin Revolved Surface - Adds material. Choose different sketches from intersecting or non-intersecting sketches to create the revolve with the Selected Contours pointer.Revolved Surface

13 Copyright Planchard D Feature Modeling - Feature (Cont:) Draft Feature. Removes material inward, Adds material outward Why add a draft?

14 Copyright Planchard D Feature Modeling - Feature (Cont:) Wrap Feature: Adds and removes material, again it depends

15 Copyright Planchard D Feature Modeling - Feature (Cont:) Extruded Cut – Can not be a base feature. Why?Extruded Cut Removes material. Think intelligent design – design intent. Select the proper End Condition: –Blind –Up To Vertex –Up To Surface –Offset From Surface –Up to Body –Mid Plane

16 Copyright Planchard D Feature Modeling - Feature (Cont:) Revolved Cut – Can not be a base feature. Why?Revolved Cut Removes material. Centerline Revolve profile about an axis Revolved Cut Feature. Removes material. Note: The location of the origin!

17 Copyright Planchard D Feature Modeling - Feature (Cont:) Shell – removes material. Can not be a base feature.Shell

18 Copyright Planchard D Feature Modeling - Feature (Cont:) Fillet – removes material. Can not be a base feature. Removes / Blends (outside) corners and surfaces.Fillet

19 Copyright Planchard D Feature Modeling - Feature (Cont:) Chamfer – removes or adds material. Can not be a base feature. The chamfer tool creates a beveled feature on selected edges, faces, or a vertexChamfer

20 Copyright Planchard D Feature Modeling - Feature (Cont:) Linear Pattern - Adds or removes material. Can not be a base feature.Linear Pattern Pattern Feature: Holes, cuts, etc. removes material. Pattern Feature: Ribs, Extruded Boss, etc. adds material. It depends

21 Copyright Planchard D Feature Modeling - Feature (Cont:) Circular Pattern – Adds or removes material. Can not be a base feature.Circular Pattern Pattern Feature: Holes, cuts, etc. removes material. Pattern Feature: Ribs, Extruded Boss, etc. adds material. It depends

22 Copyright Planchard D Feature Modeling - Feature (Cont:) Think ABOUT patterns in general. How would you create this dandelion?

23 Copyright Planchard D Feature Modeling - Feature (Cont:) Mirror Feature: Holes, removes material. Mirror Feature: Ribs, Extruded Boss, etc. adds material. It depends!! MirrorMirror – Adds or removes material. Can not be a base feature.

24 Copyright Planchard D Feature Modeling - Feature (Cont:) Cosmetic Appearances This is different than material properties of the assembly!!! Does not add or Subtract material.

25 Copyright Planchard D Feature Modeling - Feature (Cont:) Cosmetic Appearance!

26 Copyright Planchard D Feature Modeling - Feature (Cont:) The Equation Driven Curve tool is a 2D sketch spline driven by an equation. This Sketch entity provides the ability to create a curve by specifying the equations that defines the curve. Equations defining a curve specify Y as a function of X. You can use any function that is supported in the Equations dialog box.

27 Copyright Planchard D Feature Modeling - Feature (Cont) The Curve Through XYZ Points feature provides the ability to either type in (using the Curve File dialog box) or click Browse and import a text file with X-,Y-, Z-coordinates for points on a curve. Generate the text file by any program which creates columns of numbers. The Curve feature reacts like a default spline that is fully defined. Think about creating a Cam!

28 Copyright Planchard D Feature Modeling - Feature (Cont:) Hole WizardHole Wizard – removes material. The Hole Wizard feature provides the ability to create cuts in the form of holes. This feature provides the ability to create holes on a plane as well as holes on planar and non- planar faces. Holes on a plane allow you to create holes at an Angle (3D Sketch) to your feature. When you create a hole using the Hole Wizard, the type and size of the hole is displayed in the FeatureManager design tree.

29 Copyright Planchard D Feature Modeling - Feature (Cont:) Hole WizardHole Wizard – removes material. The Hole Wizard feature provides the ability to create cuts in the form of holes. This feature provides the ability to create holes on a plane as well as holes on planar and non- planar faces. Holes on a plane allow you to create holes at an Angle (3D Sketch) to your feature.
