Areas of Expertise:

Synchronous and Ordered Part and Sheet Metal modeling



Our Challenge

Design challenges to be solved

Design and model a sheet metal enclosure in the context of an assembly

How Solid Edge meets the challenge

Solid Edge is the best solution for modeling sheet metal parts. The synchronous tools and process specific sheet metal commands make modeling sheet metal parts quick and easy in Solid Edge!



Hands-on Sheet Metal Modeling

Open the Assembly

Open the top level assembly called: 003700_A.asm




Pulling Flanges from the top level

In Solid Edge ST5 you can drag flanges from the assembly level on synchronous sheet metal parts

Switch to Face Priority (CTRL + Spacebar)

Select the four thickness faces to drag all flanges at once

After selecting the first face, press the spacebar for add/subtract mode

No need to hold down the CTRL or Shift keys to multi-select




Pulling Flanges from the top level

Select the short arrow and begin to drag the sides

Set the option to Material Inside from the quick bar

Make the height of the flanges 70.00 mm




Pulling a Partial Flange from the top level

Select the thickness face near the left side, on the edge with the wires, and start to drag

Select the option to create a partial flange from quick bar

Make the flange 27.00 mm long




In-Place-Activate into the housing

Now it's time to go into the part to continue modeling

Switch to Part Priority (CTRL + Spacebar) and double left click the part to edit in place.




Edit the Partial Flange

Zoom in on the flange and add 40.00 mm PMI Smart Dimension for the width and lock it

Add 27.00 mm dimension from the edge




Locking Keyway

Display the sketch "Lock Slot"

Add an 8.00 mm diameter hole centered on the midpoint of the sketch




Add Slot

Add 4.00 mm Slot in the flange using the sketch




Add Rounds and Gussets

Break the corners on the partial flange

Use Face selection and make the radius 5.00 mm

To strengthen the flange we will add two gusset features to the bend

Fit 2 gussets on the bend




Mirror the Flange and Features

Fence select the flange and mirror about the Front plane




Add Mounting Dimple

Show the Mounting Dimple sketch

Add the dimple using these parameters

4.00 deep

45° Taper angle

All rounding 1.00 mm




Add Mounting Hole

Select the Hole command and set to a simple 5.00 mm diameter through hole

Touch the edge of the dimple to locate on its center




Mirror Mounting Features

Mirror the dimple and hole about the Front plane

Mirror the two mounting features about the Right plane




Bottom Vent

Show the Bottom Vent sketch

Create a 5.00 mm wide Flat ended slot on the center horizontal line in the sketch




Bottom Vent

Create a Fill Pattern of the Slot feature using the region of the sketch

Accept the region

Change spacing along x to 10.00 mm and the spacing along y to 55.00 mm

DO NOT ACCEPT YET……




Bottom Vent

Click the Suppress Instance button from the Fill Pattern Quick Bar

Enable the option for the instances to touch the boundary

Accept and the option (green checkmark)

Accept to finish (green checkmark)




Air Flow Hole Pattern

Display the Air Flow Patterns sketch

We will b adding clearance holes for the mounting bolts for the fans as well as add vent holes for the fans for air flow





Run the hole command to place 10 simple 4.00 mm diameter thru holes on the centers of the sketch circles





Select a hole in the center of the large circle and run the Fill pattern command again and pick the region create by the large circle

Set the spacing to 6.00 x 6.00

Accept





Click the Fill Pattern edit handle to edit the instances of the pattern

Click the Suppress Instance button from the Fill Pattern Quick Bar

Suppress the 4 instances shown by clicking their green dots





Repeat this procedure to create the vent holes for the other fan




Louver Pattern

Rotate the model to the opposite side and display the Louver Pattern sketch

Create a Formed-end Louver

Place the Louver somewhere inside the upper left corner of the sketch




Louver Pattern

Create another Fill Pattern using the sketch region

12.00 spacing along Z and 70.00 along X




Wire Clearance Slots

Show the Wire Slots sketch

Create a Slot feature using the sketch

Select the slot and copy it 45.00 mm along Y




Lid Mounting Holes

On the View tab, select the option to toggle the "Previous Level" or click CTRL+Q

Click the checkbox next to the last part in the PathFinder to display the lid part




Lid Mounting Holes

Click the Project to Sketch command

Lock the plane to the side face of the part by clicking F3 while hovering on the face

Select the inside or outside circle of the hole in the lid to project onto the face




Lid Mounting Holes

Select the region created by the sketch and cut through all




Lid Mounting Holes

Hide the Lid by unchecking the box in PathFinder

Break the 2 corners shown on both sides

8.00 mm Radius




Lid Clearance

We need to add some clearance to remove interference when opening the lid

Select the thickness face of the back edge

Disable Live rules (U)

Drag the back edge face down 16.00 mm

Click CTRL+Q to hide the background parts




Flatten the Housing

On the Tools tab click the Flat Pattern radio button

Click the bottom face as the "face to be oriented upward"

Click and Edge to define the X-Axis




Add Bend Table

Click the Synchronous node to return to the bent state




Add Bend Table

Add a Bend Table




Add Bend Table

Reorder Bend 3 to Bend 1

Click "Move Up" after selecting Bend 3

Note the Balloons also update

Click OK to dismiss




Create a Drawing

Save the file

Click Start button > New > Create Drawing

Run the Drawing View Creation Wizard

Use the option to place the Flat Pattern




Create a Drawing

Place as a Top view

Click Finish




Create a Drawing

Add an isometric view

Run the View Wizard

Click OK to the first screen and Next on the second screen to place the Designed Part

Select iso and Finish to place the isometric view on the sheet

Change the scale to 1:2 and the display to shaded with Edges

Place next to the title block




Create a Drawing

Now let's add the Bend Table to the Flat Pattern

On the Columns Tab in the Bend Table Properties, remove the Feature and Included Angle columns




Create a Drawing

Add the Bend table to the drawing sheet

Save and close the draft file




Modify the Lid

Click CTRL+Q to show the background parts

Show the Lid again by checking the box in PathFinder

Double left mouse click the Part name in PathFinder to in-place-activate into the lid part




Modify the Lid

We have a design change where we want the pivot tabs to be on the inside of the housing instead of on the outside

Select the outside face of the nearest tab

Restore the default Live Rules!

We want to offset the steering wheel from the face to create a clearance between the outside of the tab and the inside face of the housing

Press the Shift key and select the Arrow of the steering wheel and offset it 1.00 mm off of the face




Modify the Lid

Drag the face in to a keypoint on the inside edge of the housing




Modify the Lid

The Symmetric Live Rule adjusts the tab on the opposite side of the lid the same distance




Add Beads

To strengthen the lid we will add a bead feature

Select the Bead command and change the options as shown

Add the bead to the "X" sketch




Add Beads

To create a "handle" in the lid we will add another bead feature of another type

Select the Bead command and change the options as shown

Add the bead to the remaining sketch




Assembling

Close and Return to the top level assembly

Select the lid part and in the relationships pane, delete the ground relationship

Run the Assemble command and create an alignment between the hole in the lid and the hole in the housing

Delete this Ground relationship




Show Motion

Select the Drag Component command

Accept the default options and click OK

Use the free form drag option and click on the lid and drag to show it opening and closing

Don’t click – Press Reset when finished dragging to return to its original position




FINISHED DESIGN
