Warning on House keeping l All parts, assemblies and drafts associated with a given assembly should be kept in the same directory or folder. l Do not attempt to move or rename parts after they have been placed in an assembly. - An assembly file does not contain the actual parts themselves. It is simply a set of links to parts/locations and a definition of how they go together. The advantage of this is that if an individual part is modified, the changes are automatically reflected in the assembly.
Warning on House keeping l Everytime an assembly is opened in Solid Edge reads the assembly information, gathers together all the parts and reassemblies them. l If a part is renamed or moved solid edge will not be able to find it and it will dissappear from you assembly. l The information defining the locations of the files are contained in the assembly links (next slide)
Assembly Links l To check the locations from which files have been assembled check the file links under Edit Links
The Edge bar l The edge bar serves a number of usefull purposes and can be activated by selecting the edgebar icon on the main toolbar. Two uses are: - To Display Existing parts within an assembly - To display the available the construct an assembly i. e. the parts library.
Assembly Pathfinder l The assembly path finder shows parts and subassemblies already contained within an assembly l The lower section shows the assembly relationships for the selected part.
Parts library l The parts library displays parts available for assembly in a specified directory. l The lower part displays a preview of the selected part. l Assemblies can be created by: - Assembling existing parts - By creating a part in place
Placing parts Place part tool l Create in place l Place from file
Create in place
Place from file To Create in place l Activate edge bar l Select parts Library tab l Select folder containing parts required. l Drag and drop parts into graphics area.

Mate/Align/Insert Relationships Mate Align Insert
Align with Offset l Where two faces are require to face the same direction but to be displaced from one another by a specified amount
Align with Floating offset l Where to faces are required to face the same direction but are diplaced from each other by an unknown amount.

Moving Parts in Assemblies Before all assembly constraints are applied a part can be move using move part: l Linear, Rotate, and Dynamic l Blue axis appear to use to translate or rotate part.
*How to use Connect Relationship? l Connect relationship should be used in conjunction with other relationships, meaning they will help define a mate, align or angled relationship better (e. g. a pivot point for an angled relationship) l Connecting parts with opposing draft angles l Consider Connect as a “working” relationship rather than a “stand-alone”
*The Connect Relationship l First get the two parts constrained as best as possible.
*Connect (con’t) l Place your next critical relationship
*Connect (con’t. ) l Firm up the design with connects
*The Angle Relationship l After defining the two faces to measure too, the system will generate the pivot point automatically (5 th step skipped) l Axial aligns will dictate pivot point (5 th step skipped) l Reference planes can be used! l Different result if two model edges are used
*The Angle Relationship- 2 surfaces l The angle is applied to the surfaces according to the X and Y orientation - surfaces be 270) may flip (90 may
*The Angle Relationship - 2 Edges l User must give a pivot axis perpendicular to the selected edges (5 th step) l System ignores X and Y orientation and works off a “straight” coordinate system. l An axial align must pre-exist or the system will prompt for this relationship!
*The Angle Relationship - 2 Lines l First element is the measure too l Second element is the origin element l Quadrants: -1 is cc - 2 is c - 3 is oo / c - 4 is oo / cc
*Exploding your assembly l Automatic Explode l Manual Explode l Editing the Results l Un-exploding
*Automatic/Manual Explode Automatic Select what you do and don’t want to explode. l Users have no control over explode direction l Unexploded parts and subs stay put. l Manual Explode Users can explode parts in any direction they desire. l User must select every part to explode l
*Editing Exploded Assemblies l Moving l Re-positioning l Collapsing l Adding Joggles l Un-Exploding
*Part Display Status l Show l Hide Part part l Show only (hides all others) l Activate part (full part details in mem) l Inactivate part (min rep to save mem)
*Why de-activated? l Saves Memory l Reduces file initialization l No impact on relationship solving l No impact on rendering l New Pathfinder Icons
*Unloading Hidden Parts l Any part that is hidden can be unloaded from memory! l No effect on solving!
*Using Sketches l One sketch can be used on multiple parts l Sketch changes, all related parts change.
*Using Sketches l Be sure to turn on the “link” when including an edge from a sketch. l There are limits for parts linked to an assembly sketch (coping; deleting) l Use the Break Links command to break the associative link to the sketch. l Each part must be edited separately
