• 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

• 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.

• 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.

  an Assembly (20 min.) - Creating a Tube Part
  with XpresRoute (optional) (30 min.)
• Homework 5 in 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.)

• 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.

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

• 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.

• 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.
