• What are some new modeling tools in ST8 that will help

me do my job faster and easier?

• Tools and techniques in the Ordered environment you

may have never considered using.

Part Modeling: A Hands-on Experience



New Modeling Tools in Solid Edge ST8

• Pattern by Table

• Can be used for replicating features in a Synchronous or Ordered part

that does not conform to a rectangular or circular pattern.

• Can be used to drive patterns of features in mating parts that can

be linked to the same spreadsheet for their pattern locations.



Pattern by Table

• The Pattern Table (Microsoft Excel spreadsheet):

• The columns of the table are used for

location and orientation

• Column A = +/- Coordinate along the “X” axis

• Column B = +/- Coordinate along the “Y” axis

• Column C = +/- Angle relative to the parent instance

• +/- “X” and +/- “Y” Axis directions are set by selecting a predefined

coordinate system as part of the patterning steps

• Row 1 is always the coordinates for

the feature/features to the pattern.

• Spreadsheet Restrictions:

• No Header/Title row for columns

is permitted.

• Only columns A, B and C

may contain +/- numeric values.



Pattern by Table

• Open CONTROLLER.asm from the 01-Controller folder.

• Change the configuration to 02-All to see the button pad.

• The layout of the buttons in the button pad are already linked to

a Pattern by Table driving spreadsheet.



Pattern by Table

• Select the BODY-FRONT part to edit in place.

• Note the slot for the first button in the upper left.

• This will be the slot we will use as the parent to

pattern the remaining button slots using a spreadsheet.

• Open BUTTON_LOCATIONS.xlsx from the Controller folder

• Remember the first row is the “X” & “Y” locations of the

parent instance.

• HINT: A value of 0,0,0 indicates the rest of the

coordinates are being measured from the

parent instance.



Pattern by Table

• Click “Top” on the view cube in the lower right of the graphics window

• Zoom up on the button slot.

• Fence Select the slot.

• Be sure not to get background faces in the selection set



Pattern by Table

• On the drop-down menu for Pattern, select the Pattern by Table command.

• The first step is to identify the coordinate system that will determine

the +/- “X” and “Y” directions.

• Select the Base coordinate system



Pattern by Table

• In the Instance Table, Browse to the BUTTON_LOCATIONS.xlsx



Pattern by Table

• In the Instance Table, change the Reference Point option to Selected Keypoint.

• In this example, the locations specified in the spreadsheet are originated from the center of the slot

feature that we are patterning.

• Remember the feature to pattern location is the first row in the spreadsheet.

• If the locations were measured from the coordinate system, the first row “x, y” locations would contain

non-zero values



Pattern by Table

• In the QuickBar, change the keypoint option to locate Midpoints.

• Select the midpoint of the centerline sketch for the slot

feature we are patterning.

• Note the pattern preview update.

• Click the green checkmark to accept the pattern



Pattern by Table

• Hide all sketches and coordinate systems from the Right Mouse Button context menu.

• Now let’s make a change to the button locations via the

spreadsheet locations and orientations.

• Note the colored rows in the spreadsheet correlate to the columns

of buttons in our model.

• This is not required and is simply

being used to help us visualize

our goals.



Pattern by Table

• We want to first eliminate the center 2 rows of slots in each column.

• Select the middle instances in each column in the spreadsheet

• Press the CTL key while selecting each row to add to the select set to delete.

• Rows 2, 3, 6, 7, 10, 11, 14 and 15

• Right Mouse click and select Delete



Pattern by Table

• After deleting the rows, Save the spreadsheet.

• Mouse over the Solid Edge graphics window and the pattern will update automatically



Pattern by Table

• Next we want to centralize the middle columns of buttons to form a circular looking pattern.

• We need to move the top two buttons down (11.00 mm) and rotate them to the opposite direction of their

current rotation.

• Edit columns B (“Y” value) and C (Rotation Angle) of rows 3 and 5

• We need to move the bottom 2 buttons straight up 11.00 mm.

• Edit column B (“Y” value) of rows 4 and 6



Pattern by Table

• Subtract 11.00 mm from cells 3B and 5B = -11

• Change the –20 to a +20 for cell 3C

• Change the +20 to a -20 for cell 5C

• Add 11.00 mm to cells 4B and 6B = -55

• SAVE the spreadsheet and mouse over

to the Solid Edge window to see the update



Pattern by Table

• Next we want to add a new horizontal button directly in the center of the pattern.

• This will be a new column in the pattern = a new row in the spreadsheet.

• Right Click on row 5 and click Insert to add a new row 5 to the spreadsheet.

• Highlight the 3 cells in the new row (5) and Right Click again and click Format Cells.

• Change the Background Color on the Fill tab to a shade of pink to differentiate it is a new column.

• Again, this is not required and is used just for clarity.



Pattern by Table

• To add a new button the middle we need to fill in the “X”, “Y”, and orientations fields.

• Cell 5A = (126/2) = 63 for “X” value

• Cell 5B = (-66/2) = -33 for “Y” value

• Cell 5C = same as the parent orientation = 0

• Save the spreadsheet and mouse over to the Solid Edge window to update the model



Pattern by Table

• Close and return back to the assembly.

• Notice the button pad is out of date to the spreadsheet changes.

• To update the changes in the BUTTON PAD, simply select the

part and click Edit In Place and it will update automatically.



Pattern by Table

• Close and return back to the assembly

to see the final design!



New Modeling Tools in Solid Edge ST8

• “Like Me” Pattern – Pattern Recognition

• Automatically recognizes patterns of selected geometry in a synchronous model.

• Perfect for editing geometry on an imported “dumb” model!



Pattern Recognition (synchronous only)

• Open DH2-00131_A.par from the 02-LikeMe folder.

• This is a real part from a customer who allowed us to

use this for demonstration.

• Notice this is an imported part and that there are no

features listed in the PathFinder.

• Also notice the holes in the center ring and slots are

spaced between the outer retainer arched features.




• First we want to recognize the cylinders as Hole features so we can modify them.

• Under Hole on the Home Tab, click Recognize Holes

• The center 52.00 mm diameter bore is recognized along with the

twelve 4.83 mm diameter holes.

• Placing your mouse over a row will highlight the corresponding

holes in the model.




• Let’s change the simple hole type of the 12 holes to tapped holes by clicking on the Hole Options icon.

• Set the standard to ISO Metric

• Change the type to Threaded

• Change the size from the list to M6 x 0.5

• Change depth to Finite Extent

• Set the hole depth to 20.00 mm

• V bottom angle

• Change the Thread extent option: To hole extent.




• Let’s rename the Holes to:

• M6 Threaded Holes

• Center Bore

• Click OK to dismiss the

Hole Options and

Hole Recognition dialogs

• Now there is a list of 12

individual threaded holes.




• Next let’s turn this into a pattern of holes.

• Under Pattern on the Home tab click Recognize Hole Patterns.

• Fence select the model and right click to accept.

• Note it finds the circular pattern of the 12 holes.

• Rename Pattern 1 by Double-clicking on the Feature Name field.

• Change the name of Pattern 1 to PATTERN_ThreadedHoles.

• Do NOT click OK just yet.




• Before accepting the pattern, we want to redefine the master occurrence

• Rotate the model like shown below – near to a top view

• Select the Define Master Occurrence icon from the dialog box.

• Select the edge of the hole opposite the Y axis

arrow direction and just to the right as shown.

• After selecting it, hover your cursor over the icon again

in the dialog and you should see the indication of the

master occurrence.

• Click OK to accept the pattern definition.




• Not only can Solid Edge ST8 recognize patterns of holes, it can also recognize patterns of selected

geometry.

• Hide the PMI dimensions by unchecking it in PathFinder.

• From the top view, fence select the same slot shown in the image below.




• Under Pattern on the Home tab click Recognize Patterns.

• Rename the Pattern 2 by Double-clicking on the Feature Name field.

• Change the name of Pattern 2 to PATTERN_Slots

• Click OK to accept the pattern definition

• Hide the PMI dimensions




• Finally, lets recognize the retainer geometry:

• From the Top view again, fence select the bottom arched geometry and

rounding shown in the image.




• Once again, under Pattern on the Home tab, click Recognize Patterns.

• Rename the Pattern 3 by Double-clicking on the Feature Name field.

• Change the name of Pattern 3 to PATTERN_Retainers

• Click OK to accept the pattern definition

• Hide the PMI dimensions




• We can make changes to the pattern occurrences via the Variable Table

• From the Tools tab, click on Variables command.

• Scroll to find the Pattern Variable “…XCount” entries

• Notice that the Threaded Holes and Retainer features have equal occurrences and that the number of

Slot features is ½ the number of occurrences as the others.

• Note: The variables in the table may not be in the same order as shown below.




• Let’s relate these variables together:

• Double click on the PATTERN_Retainers_XCount variable name.

• Select the entire text string and right click to copy it to the clipboard. (Ctrl+C)

• Double click into the Formula cell of the PATTERN_ThreadedHoles_XCount row, right click and paste

in the variable name to make them equal. (Ctrl+V)




• Double click into the Formula cell in the PATTERN_Slots_XCount row and paste the variable name

followed by: /2

• Change the value of the PATTERN_Retainers_XCount value from 12.00 to 8.00

• The formulas will recalculate and update the model accordingly.

• Dismiss the Variable Table




• Note that originally the slots and threaded holes were centered between the retainer features so let’s fix

that using synchronous technology.

• Select the parent slot feature and threaded hole.

• Fence select the slot and then select the

threaded hole.

• Shift+Click the origin (center) of the steering wheel

and drag it to the edge of the large center bore.

• It will snap to the center and click to place it.




• Shift+Click the bearing knob on the end of the right arrow

to start to rotate the steering wheel.

• Select the center of the threaded hole so that the arrow points

directly at it.




• Select the torus of the steering wheel to initiate rotating the selected geometry.

• Change the keypoint filter to locate Midpoints.

• Select the midpoint of an arc edge

between the retainer features.




• Notice how the pattern locations update

and we get the final result we are looking for.

• How could you even begin to do this

in an Ordered model without recreating it?



Other Modeling Tools in Solid Edge

• Let’s explore under-utilized tools for modeling complex parts in Solid Edge.

• Cross-Curves

• Multi-body

• Convert to curve

• Replace face

• Redefine surface



Modeling Tools for Complex Parts

• Open 5086955-A.par from the 03-Complex Shapes folder.

• Collapse the Sync feature tree.

• Expand sync sketches.

• Show the first sketch (Paddle Profile).

• Sketch of the Paddle Arm from the top view.

and the second sketch.

• Use the “Select from Sketch” selection option for both curves.

• Hide the Paddle Step Profile sync sketch.

• Show the Synchronous curves to display the

top inside guide curve.




• Create a sketch.

• Use Plane Normal to Curve and select the 31.00 mm radius arc.

• Drag to about .50 along the arc and click to place the sketch plane.

• Zoom out and rotate the model slightly to see the sketch elements.




• Create a closed profile by creating 4 lines connecting to the 4 pierce points of the outer arcs on the

Paddle profile sketch and the pierce points of the cross and derived curves.

• Accept and finish the sketch profile.

• Show the remaining Ordered sketches (5) by clicking the checkbox for

each one in the Pathfinder.

• These sketches were created the same way.




• You can use Multi-Body technique for modeling complex parts in sections.

• Add Body

• Add Part body option

• MixerPaddle-Arm




• Create a Loft between the closed sketch profiles (6).

• Be sure to select each profile such that the origin for each

lofted profile is the same relative corner (upper left).

• Right click to Preview.

• DO NOT CLICK FINISH




• Go to the Guide Path step and select the paths connected to each corner.

• Right click to accept between each selections.

• Preview and Finish.

• MixerPaddle-Arm is added to the Design Bodies

in PathFinder.

• Hide all sketches and curves.




• Add a 3.00 mm Constant Width Blend to the upper edges.

• Selecting the top face and one side face.

• Preview and Finish but stay in the command.

• Select the top face and the opposite side – make 3.00 mm.

• Finish the command




• From the Surfacing tab, select the Replace Face command to redefine the end face

of the arm to match up with the inside cylinder of the original body.

• Add a 5.00 mm round to the corner on the arm.




• Use Replace Face command again to redefine the 5.00 round of the arm to match up with the inside round

of the original body.

• Now the end of the arm perfectly matches the inside surface of the original body.




• Next we can cutaway the Original body where the arm will connect.

• Use the Subtract command to subtract the

MixerPaddle-Arm from the MixerPaddle-Body.

• MixerPaddle-Body is the Target body.

• MixerPaddle-Arm is the Tool body.




• Hide the MixerPaddle-Body and MixerPaddle-Arm by unchecking

them in the PathFinder.

• Show the MixerPaddle Construction body by checking it in the Pathfinder

• Right mouse click on the MixerPaddle body and toggle it to a design body.

• Double click on it to make

it the Active body.




• Let’s add contour to the bottom flat face of the Paddle.

• Select the Redefine command from the Surfacing tab.

• In the options be sure Replace faces on solid body is checked

• Select bottom face of Paddle.

• Select the Insert Sketch option using Plane Normal To Curve.

• Use the bottom edge to place a curve near the middle of the surface.

• Click Next and Finish




• Note the defining sketch is added just above the Redefine surface feature.

• Select the sketch and click the Dynamic edit button.

• Drag the center node down to add a concave contour to the surface.




• Hide the sketch and show the MixerPaddle-Arm body.

• Double click the MixerPaddle-Arm body to make it active.

• Once again use Replace Face to match the end face of the arm to the concave face of the MixerPaddle.




• Next we will subtract the Arm from the Paddle where they intersect.

• Use the Subtract command to subtract the MixerPaddle-Arm from the MixerPaddle.

• MixerPaddle is the Target body.

• MixerPaddle-Arm is the Tool body.




• Create a Thin wall feature in the Arm and open the bottom and end faces.

• Set wall thickness to 2.00 mm




• Turn on the display of all 3 design bodies

• Using the Union command, unite all 3 bodies

into one Design body.

• Select the active body as the Target

• Select the other 2 bodies as the Tool and accept.




• Complete the design by adding 3.00 mm rounding at the intersecting edges.
