4 What you will learn Starting the Frames application Creating the framework Placing frames Frame options (including corner treatments) Frames Quick Bar Associative to Cross Section Editing frames Editing frame paths Editing frame positions Editing frame end conditions (including Extend/Trim frame) Coping joints Creating custom frame component (including defining hole locations) Creating a frame drawing Beam simulation Q&A Page 4

5 Starting the Frames Application The Frames application is only available from within the Assembly environment Procedure for entering and exiting the Frames application Step 1. Step 2. Step 3. Open a new assembly file To start the Frames application, Tools tab Environs group Frame Design The tools needed to create paths that define the framework are located in the Home tab, Segments group (1) The Frame command (2) creates frames Step 4. To exit the Frames application, click the Close Frame command in the Close group 1 2 Page 5

6 Creating the Framework The framework can be a combination of Sketches 3D line segments Edges of components in an assembly (new in ST6) Page 6

7 Placing Frames After the framework design is complete, create frames that follow the body edges/sketch/3d line segment paths To create frames, choose the Frames command from the Frame group The command would show the following Quick Bar Page 7

8 Frame Options To display the Frame options, click the Options button on the Frame Quick Bar Page 8

9 Frame Options Corner Treatment Options Apply corner treatment: (1) Miter A miter cut is applied to corner(s) (2) Butt1 Material is removed from the longest member (3) Butt2 Material is removed from the shortest member Page 9

10 Frame Options Corner Treatment Options Apply radius: A fillet is applied at the corner(s). The result is a single frame spanning the selected segments Extend frame component: Each frame is extended by a specified (+/-) length No corner treatment: No frames are trimmed. Each frame is the length of the path element. Page 10

11 Frame Options Frame Component Location Frames components are stored in unmanaged and managed locations browse for an unmanaged frame component select a managed frame component from the Standard Parts Library Click the folder icon on the Frame Quick Bar to browse for a frame component The default folder is controlled from Applications button Solid Edge Options File Locations tab Page 11

12 Frame Options Frame Component Location Store frame components in a common location accessible to all company frame designers Solid Edge delivers a sample set of frame components The sample frame components are found in the Program Files\Solid Edge ST6\Frames folder Page 12

13 Placing Frames Select Path Step Recently Used Components Select Cross Section Component Locate Body Edges Selection Type: Single Chain Face Body Accept Deselect The Frame Options button is available at all times within the Frame command The first step in the Frame command is the Select Path Step While in the Path Selection Step, browse for a frame component or select a component from the Recently Used Component list You have the option to select Sketch/3D segments using Single/Chain selection type or edges of components using Single/Chain/Face/Body selection type When the path elements are selected, click the Frame Accept button Deselect the selected path elements by clicking the Frame Deselect button The frames are placed after accepting the paths Click Finish to end the placement step Page 13

14 Demonstration 1 Page 14

15 Editing Frames Associative to the Path The frame will be associative to the sketch, 3D line segment or body edge selected For example, if the user makes a change to the solid, the frame will update automatically Page 15

16 Editing Frames Associative to the Cross Section The frame will be associative to the cross section component used to create the frame. If the cross section is modified, the frame updates to the change For example, here we simply change the 3 in dimension to 4.5 in and the frame updates to the change Page 16

17 Editing Frames Ways to Edit Edit a frame definition during creation or after the frame command is finished Edit frame paths, position, end conditions and component type PathFinder In PathFinder, notice Frame Components collector (1). Whenever you create frames you will get a Frame Components collector. Control the display of all frame components by right-clicking (1) and then by clicking Show/Hide All frames created in a single operation are grouped as a Frame set (2). Turn on/off the display of the frame group Each frame in the group is a part file (3) with the filename of the frame component used. Turn on/off the display of any part in the group Page 17

18 Editing Frames Ways to Edit Select the Frame group or a single frame to edit The quick edit options allow you to go directly to the focused area to make the changes needed whether it is the whole frame or just one piece of the frame The same quick edit options are also available on the RMB click menu Page 18

19 Editing Frames Edit Cross Section Step Click the Edit Cross Section button Angular Orientation of Cross Section Define Handle Point Flip Cross Section Select New Cross Section Component You can select the frame and edit all cross sections in the frame or select a component in the frame and edit only the cross section for that component Page 19

20 Editing Frames Edit Cross Section Step On the Quick Bar, specify the angular orientation of a frame cross section relative to the path You can also use the Arrow keys to shift components, the N key to rotate components Angular Orientation of Cross Section Page 20

21 Editing Frames Edit Cross Section Step You can position frames using snap points. Snap points are cross section sketch keypoints, cross section range box points, and the cross section centroid. To display the frame snap point commands, you must first select the Define Handle Point button on the Quick Bar Define Handle Point Show Default Snap Point (blue) Keypoint Show Current Snap Point (green) Show Cross Section Centroid (yellow) Show Range Box Points (red) Locate Cross Section Sketch Keypoint (activates the keypoint pull down menu) Example of locating a keypoint on the cross section Page 21

22 Editing Frames Edit Cross Section Step Use the Select New Cross Section Component button to select a new frame cross section Select New Cross Section Component Use the Flip Cross Section button to flip the cross section You can also use the F key to flip the cross section Flip Cross Section Path Page 22

23 Editing Frames Edit End Conditions Step Select a single frame component Click the Edit End Conditions button The handle points for all of the end conditions of the entire frame are displayed with the handle point for the selected frame component automatically selected Do one of the following: Right-click to accept the automatically selected handle points OR Select the handle point of adjacent frame components to modify the end condition between the two components and click the Accept button Page 23

24 Editing Frames Edit End Conditions Step If the entire frame is selected, then clicking the Edit End Conditions button will Start the edit of the entire frame Display the Frame Options dialog All the end conditions of this frame can be changed from the Corner Treatment Options on this dialog Page 24

25 Editing Frames Edit End Conditions Step The Edit Cross Section step Miter None Butt 1 Butt 2 Extend/Trim You can change the end condition to a Miter/Butt 1/Butt 2/Extend/Trim/None When the end condition is changed to None, the Quick Bar provides additional options: Fillet Extend by Distance Remove Page 25

26 Editing Frames Extend/Trim Frame Frame components can be extended to or trimmed by a plane or a face or a body of a part within an assembly To do this, in the Edit Cross Section step, select the Extend/Trim option. Then there are options for selecting the frames that you want to extend or trim Extend/Trim Select a plane/face/body to which the frame component should extend/trim to Select a frame component associated with the end point Auto-select all frame components associated with the end point Page 26

27 Coping Joints In the Frames Options dialog, you can apply coping to non-mitered joints Coping turned OFF Coping turned ON Page 27

28 Single Frame for Collinear/Tangential Segments In the Frames Options dialog, you can specify to create: Single frame for collinear segments Single frame for tangential segments Page 28

29 Single Frame for Collinear Segments Single frame for collinear segments option When this option is ON, it creates a single frame for all segments that are touching and collinear When this option is OFF, it creates a separate frame for each segment if they are connected and collinear with another segment Page 29

30 Single Frame for Collinear Segments When multiple collinear segments meet at a vertex and Single frame for collinear segments option is off we create two frame members for any two collinear segments In the Edit End Conditions step, the Next Collinear Option can be used to specify the members to form the complete frame member set. This trims the other frame members Next Collinear Option Page 30

31 Single Frame for Tangential Segments Single frame for tangential segments option When this option is ON, it creates a single frame for all segments that are connected and tangential When this option is OFF, it creates a single frame for each disjoint segment if they are connected and tangential with another segment Page 31

32 Demonstration 2 Page 32

33 Creating Custom Cross Section You can create a frame using a custom cross section First, create a model representing the shape and size of the cross section The complete cross section of the component must reside in either the first feature or first sketch While in the Profile/Sketch environments for both Ordered and Synchronous modes, run the new ST6 Frame Origin command Define the default origin and relative orientation of the frame cross section This replaces the old FrameComponentsUtility.exe Point Step Clear All Geometry Orientation Step Page 33

34 Creating Custom Cross Section In the Point Step, select a point or keypoint to define the default frame origin If the frame origin is not defined, we will use the centroid of the cross section as default In the Orientation Step, click on a line segment in sketch to define the orientation The geometry selected will be attributed as shown Finish and Save the component Page 34

35 Defining Hole Locations A frame component may contain information on where holes can be drilled Add cylindrical construction surfaces to the frame component to define these hole locations Use the Retrieve from Cross Section Component command on the frame to view these surfaces Assembly features can be created from the surfaces. A combination of the include and cutout commands can quickly assist in getting the holes in the correct location Page 35

36 Demonstration 3 Page 36

37 Creating Frame Drawings The process of creating drawings of 3D frames is the same as creating 3D assembly drawings Create a total length parts list or a cut length parts list for frame components Total length parts lists show all members of a specific pipe or frame on the same row in the parts list. This can be used to produce a list of total lengths for purchasing Select the additional columns that you want to show in a total length or cut length parts list, such as Mass (Item), Mass (Quantity), Miter Cut 1, and Miter Cut 2 The calculated cut length and mass properties consider Assembly Features Page 37

38 Creating Frame Drawings Mass (Item) will be for the single frame member Mass (Quantity) will be used if there are more of the same frame member in the list This information is also available in Assembly Reports Page 38

39 Frames Creating Drawings The uniqueness options allow the user to identify the characteristics which make a frame member unique and have its own entry in the parts list Example: You have two identical frame members, however one of them has holes placed in it using an assembly feature. Both would have the same length and miter cuts, but when you consider the Mass they are not identical Draft Parts List Options Solid Edge Options Page 39

40 Creating Frame Drawings Let s look at an example: Notice #7 and #11 they both have * in the Mass (Item) fields but the Mass (Quantity) is filled in The reason for this is that as an Item the mass is not the same for all members Page 40

41 Creating Frame Drawings Let s look at an example: When the user selects to display Mass uniqueness (Check Mass), the Parts List updates and lists each unique frame member as their own Item # Page 41

43 Frame Simulation Page 43

44 Frame Simulation Beam Elements Typically used for long slender components/frames where the cross section is relatively small compared to the length Trusses, cranes, bridges, tables I-Beams, c-channel, T-s, Square tubing Beam elements are 1-D linear elements Simpler representations than shells or solid elements Faster solve time compared to shells/solids Page 44

45 Frame Simulation Understanding How Beams Work Beams have been implemented in the Frame environment of Assembly and only works with frame objects 1-D beam elements are created along frame objects Frame Design Beam Elements and BCs Results Page 45

46 Frame Simulation Beam Element Support To use the new Beam Element analysis, you will have to go into the Frame environment Once you enter the Frame environment, there is a Simulation tab Page 46

47 Frame Simulation Create Study To create a new study Notice on the Create Study dialog there is a mesh type Beam Define the geometry for the Beam analysis In this example we can use a bridge structure as shown Page 47

48 Frame Simulation Define Loads After defining the geometry (frames) for this study, Simulation will automatically create the beams for each of the frames Once the geometry is defined the rest of the commands become active so the user can apply loads, constraints, and a mesh In this scenario, we will apply a force on the top of the frame in a downward direction Page 48

49 Frame Simulation Define Constraints The Fixed constraint is applied to the bottom 4 nodes The user can turn On/Off the frames at any time NOTE: The color of the Beam elements can be changed through the Solid Edge:Options:Simulation tab Page 49

50 Frame Simulation Mesh The next step is to Mesh the beam elements The results from the mesh are shown and of course can be adjusted if needed Page 50

51 Frame Simulation Mesh Also available in the Mesh group are 2 commands called Node and Release The Node command basically let s you create a node at a specific location A node can be placed at a midpoint or at an intersection and then an offset can be keyed in as shown above When a Node is created, it gets added to the Study Navigator Page 51

52 Frame Simulation Mesh The other option called Release which allows degrees of freedom to be released so that elements can move or rotate relative to each other Quickbar does give the options to change the color of the degree of freedom symbol, the size, and also an option to tag it By selecting the top beam the user only needs to select where to release the degree of freedom Any degrees of freedom that have been released are automatically added to the Study Navigator Page 52

53 Frame Simulation Solve and Results After solving Simulation will take the user into the Results environment where you can make several view style changes Beam Cross Section is on by default Beam Diagram can also be displayed Page 53
