SolidWorks Review

Identify and describe mates used within Assembly in SW

* Concentric- have circular features share the same origin (good for aligning holes, fasteners, screws, shafts, etc.) * Coincident- have features physically meet/touch *Parallel- have features (often planes or flat surfaces) * Perpendicular- have features (often planes or flat surfaces) remain perpendicular to each other * Tangent- have a circular feature run smoothly into a flat feature

What information/elements should be present in an exploded assembly drawing

* Exploded Assembly * Bill of Materials * Balloon Annotations * Title Block

What kind of information can be a part of the BOM

* Part names/descriptions * Quantity of parts (how many) * Part material * Part size/weight

What information does an exploded assembly provide that an assembly (normal) does not?

* Which parts are used (internal components and the back components) * How many of each part is used * How exactly each part fits together

What is the difference between center-mark and centerline

*Center-mark are used to show a circular feature, are used in the view where they appear as a circle *Centerline are used to show circular feature, are used in the cross-section view

What are all the possible elements that can be included as pat of an assembly drawing?

*Standard Views (Top, Front, Right, ISO) * Section view * Detailed view * Dimensions * Title Block

What kind of information does a good detailed drawing provide

*dimensions of a part *Information about a part's features *Information about a part's material

Describe one way that a "swept boss/bass" is different from extruded or revolved boss/bass

*extruded:adds layers in a normal direction (perpendicular to the sketch) *revolved: adds layers around an axis of rotation *swept:adds layers along a given path

What are the 5 major guidelines or "rules" of dimensioning?

1. No duplicate or excessive dimensions 2. Dimensions should be placed in the view that best shows the shape of the feature 3. Circles are dimensioned by their diameter, arcs are dimensioned by a radius 4. Avoid crossing extension lines 5. Avoid dimensioning to hidden lines as much as possible

Fillet

A curve formed at the interior intersection between two or more surfaces.

Extruded Cut

A feature that removes material from a part

Centerline

A line type that is used to indicate the axis of symmetry for a part or feature.

Chamfer

A small angled surface formed between two surfaces.

Centermark

A small right-angle cross that is used to identify the end view of an axis of rotational symmetry.

Section View

A view that is used to show details not apparent on the exterior of the part.

What are ANSI and ISO? When to apply which standards

ANSI-American National Standards Institute ISO-International Organization for Standardization IPS-ANSI; MMgs-ISO

ANSI/ISO standards

ANSI: American National Standards Institute (Inches) ISO: International Organization for Standardization (metric) Use ANSI 90% of the time

Detailed View

Additional, close- up information shown on a particular section of a larger drawing

When we have long slender parts (often Shafts) what type of view might be useful to save space on the detailed drawing?

Broken View

Loft

Connect several cross-sections together ex)shampoo bottle

Geometric Constraints

Creating relationships between objects in space. Constrain them in a particular way. Relationship Tool

Why detailed drawing of assemblies

Detailed drawings provide dimensions of the overall assembly Detailed drawings can provide information about internal components

Detailed Drawing

Drawing of an individual part providing enough information so the part can be manufactured detailed drawings provide: *important information about the dimensions of the object * Important information about certain features of our object *information about the part's material

Exercises to practice

Exercise 4 5 6 7 11

What features in SW can we use to most efficiently create an object that has planar symmetry

Extruded boss/base Extruded cut mirror features

Extruded Boss/Base

Extrudes a sketch or selected sketch contours in one or two directions to create a solid feature; adds material to the part; created from a 2D sketch.

True or false When exploding the view and moving parts away from each other, parts must be moved so that they are always aligned on their original axis

False: You have a lot of control in how you explode the view, you do Not need to keep all parts aligned with each other

What is the difference between a chamfer and a fillet

Fillets are rounded edges (provide a radius dimension) Chamfers are beveled/angled edges (provide a size and an angle dimension)

Which of the following terms are axonometric projections

Isometric

Threaded Fasteners

Major Diameter: outside diameter (largest) Minor Diameter: inside diameter (smallest) Pitch: Physical distance between threads Pitch diameter: diameter of the pitch or midpoint between major and minor diameter Thread angle: the angle between the threads

What are "mates" in assemblies

Mates establish how parts are related to each other; similar to geometric constraints in 2D sketches

How does a lofted boss/base get created in sw?

Multiple sketches (cross sections of the object) are connected together in order

Describe the difference between a part, drawing, and assembly in SW

Part- A single 3D object generated from 2D sketches Drawing- A 2D representation of a 3D object/part Assembly- Multiple 3D parts placed together with some intended purpose/design

assembly modeling

Putting the parts together to create the finishing product

What features in SW can we use to most efficiently create an object that has rotational symmetry

Revolved boss/base Revolved cut

Revolved Boss/Base

Revolves a sketch or selected sketch contours around an axis to create a solid feature.

What can be added to exploded assemblies to improve clarity for the user (how parts are supposed to fit together)

Route lines

Subtractive processes

Starting a large bulk material and removing material to get the desired shape machining/milling carving/sculpting

What does the "wrap" feature do?

Takes a 2d sketch and wraps it around a 3d face of an object

Axonometric projections

The object is rotated around one or more of its axes to reveal multiple slides

Describe one way that a "swept boss/base" is similar to extruded or revolved boss/base

They are all additive processes

Hole Wizard

Tool in solid works that is used to make holes in an object

Hole Wizard

Tool in solid works that is used to make holes in an object *Straight Tapped *Countersink *Holes *Counterbore

When might a section view be needed on a drawing

When there are some internal features that are important to communicate

When might a detail view be needed on a drawing?

When there are some small/detailed features that are important to communicate

wrap

Wrap a sketch around a surface

Broken View

breaks long parts so only the ends are shown

Holes

create a "plain" hole by cut-extruding thru a part

Additive processes

creating objects by only adding materials often layer by layer 3d printing

Bill of Materials (BOM)

document that shows an inclusive listing of all component parts and assemblies making up the final product

Mirror

mirror pieces over an axis to mirror an object

Circular Pattern

objects that circle another object; also known as centralized pattern. *ex) screw holes

linear pattern

objects that multiple in a linear way ex) oval part on house

Orthographic Projections

projection of a single view of an object onto a drawing surface in which the lines of projection are perpendicular to the drawing surface

sweep

sweep a sketch along a path ex) cup handle

What is the difference between the 2 kinds of assemblies

there's a normal assembly and an exploded assembly

Which is the correct set of orthographic projections needed to describe an object

top-front-right

What are the standard views for solidworks

top-front-right isometric
