27- Introduction to Solid Edge AssemblyAssembly is
the environment used to put parts together using
pre-determined relationships. If parts are not
dimensionally correct, problems will occur when
constraining them in Assembly. - Assembly files .asm extension - A .cfg file is
created automatically.- Do not delete the .cfg.
It contains display configuration information. - Some examples of assemblies.
28- Placing partsDrag parts from Part Librarytab in
Edgebar - Assembly RelationshipsShown in bottom pane of
Edgebar.- Ground (1st part)- FlashFit is the
default command- Mate, Align, Axial Align
and InsertHelp Topics- Place Part SmartStep
Ribbon Bar- Placing Parts in Assemblies
29- Assembly Pathfinder Icons
- Active Parts
- Parts Display
30- Un-constrained parts have six DOF (degrees of
freedom). Three rotations and three
translations. - - In general, three relationships are needed to
fully constrain a part in SE.
31- Quiz next class - Loft and Sweep definitions-
Intellisketch Pierce point (icon)- Hole
command. Types?- Helix and Revolved features.
Differences and similarities, inputs (pitch)-
Blue Dot command what is used for? - Tutorials? Save tutorial files to your own
folder on disk- Building a Slider Assembly in SE
(30 min.) - Building a Grinder Assembly in SE
(20 min.) - Producing an Exploded Asm View (30
min.) - Design Project Proposal due next class
32(No Transcript)
33- Quiz material - Sweep definition A feature
that is protruded along a user defined path.-
Loft definition A protrusion composed of
multiple profiles which are smoothly blended
together between different planes. -
Intellisketch Pierce point- Hole command.
Types? Counterbore, countersink, simple,
threaded, tapered.- Helix and Revolved features.
Differences and similarities, inputs (pitch)
A helix is translated along an axis, by its pitch
(the distance between two turns). Both
require an axis of revolution as input.- Blue
Dot command what is used for? It ensures
that two disconnected curves will intersect.
It is used to control the shape of a surface.
34- Quiz- Save your answers as you go.
- Tutorials- Modeling a Cover Associatively within
an Assembly (20 min.) - Creating a Tube Part
with XpresRoute (optional) (30 min.) - Homework 5 in class.
- Design Project Proposal Due By End of Class
35- Homework 5 C-Clamp in class- Create each
part.- Assemble the parts in SE Assembly.- All
part must be correctly assembled and fully
constrained.- Turn Reference Planes on if no
planar faces are available in the part and use
them to place relationships. - Steps- Place the Body as first part.
(grounded)- Place the Swivel next. Fully
constrain it.- Place the Screw. Fully constrain
it.- Place the Pin. Will need Reference Planes
to constrain it.- Create an exploded view of the
ASM in SE Draft. Tutorial Producing an
Exploded Asm View (30 min.)

37- SE Project 20 DISTINCT PARTS!!!- Late Design
Proposals - Project grades.- Always design in
full scale - Unit change.- Open SE only once.
Keep assembly open and use Edit to change
parts.- Flash Fit/Interference Report (Help). - Homework 5- If finished, open the Draft and the
Assembly file and come to see me in office for
grading.- All parts should be correctly
assembled and fully constrained.

39 Solid Edge Design Project Presentation1. Final
report, drawing and interference report must be
ready before presentation.2. Copy the entire
project folder from your flash drive to the
folder with your last name in the instructors
computer. Remove your flash drive.3. Open the
assembly. Should be saved with all parts showing
and in a good orientation.4. Follow the script
on the left side window.5. Be prepared to show
required features and answer questions about the
project, parts, etc.6- You have about six
minutes.Grade (ProposalReviewFinal7Presenta
tion)
40- MAE 110 Midterm - 10/25/06
- Create a folder called midterm_LastName. All
midterm files must be created in this folder. - Put your flash drive on top of the computer, no
flash drives are to be used or connected at all. - There should be no saving of any files in a
different folder anywhere. - Be prepared to leave the room when asked to.
41- Introduction to NX 3- High end product for
Mechanical Applications, 3D modeler, analysis and
manufacturing (CAD/CAE/CAM).- We will follow
handout tutorials and CAST to learn NX.- In
general students in this course learn NX faster
than Solid Edge because once you learn a CAD
system, it gets much easier the next time around,
and by now you know SE pretty well.
42- CAST- The CAST library is the little graduation
cap on the right hand side of the screen. - Its
going to be the main interface with the
tutorials.- Click the little pin button at the
top to keep it open. - It can be resized. - Toolbars- Similar to Solid Edge but more
abundant.- Turn off by right-clicking any gray
area around them.- Turn off ones we do not
need, such as Analysis.- Edgebar (SE)
Resource bar (NX)
43- New File Creation- Similar to SE- Define name
AND UNITS!!! - Dynamic Rotation with the Mouse- Click and hold
the mouse wheel and move it - at the bottom or
top of the screen will allow for VERTICAL
AXIS rotations. - at the right or left of the
screen will allow for HORIZONTAL AXIS
rotations. - near the center of the screen will
allow for MULTI-AXIS rotations. - Panning with the Mouse- Click and hold the mouse
wheel and the right mouse button. Move it around
to move the view.
44- Shortcut menus- Clicking the right mouse button
on the window will bring up a menu containing
many shortcuts that varywith the environment you
are in. - Clicking and holding theright mouse
button on thewindow will bring up a menu with
some view operations shortcuts. - Selecting Features- Open the features part
from C\Program Files\UGS\NX 3.0\ugcast\parts\ess
entials- Pass the mouse cursor over a feature.
It will highlight in purple. Left-click to
select, SHIFT-left-click to deselect. You may
also hit ESC to deselect everything.
45- - A similar function to QuickPick exists but it
is accessed with the left mouse button, not RMB
as in Solid Edge. - Applications- NX uses the concept of
Applications to switch environments. You do not
necessarily need to create a separate file for a
drawing, you switch to the Drafting environment
and the drawing resides in the same file as the
part. - The Application toolbar is used for
switching between environments. - Modeling (Part)- Right-click to edit feature
parameters.- Add icons to Utility toolbar
byclicking on the small black triangle next to
the X button.
46- Modeling Parts from Sketches- Open the
nut_bolt1 part from C\Program Files\UGS\NX
3.0\ugcast\parts\essentials- Change to Modeling
application or no toolbars will be available.-
We will draw sketches and then Extrude most of
the time.- Select the Extrude command.- Set the
Select Intent to ALL CURVES. The toolbar is
located where the SE Smartstep was.- Select the
sketch. A floating menu appears to define which
type of Extrude. (diff. from SE). - Choose
Revolved, give it a name (optional) and pick the
axis of revolution.- Two separate bodies are
created.- Use the Boolean command to Intersect
the two bodies and get the desired result.
