Duct.gif

Version compatibility

This exercise was carried out with version 27.0 (Vertex 2021).



Table of Contents




In this exercise you will learn to

  • How to use a jig to model sheet metal parts.

  • How to copy a face from another part.

  • How to create a sheet metal part from a surface chain.

  • How parts are positioned using coincidence constraints.

Functions to be used:

  • New > Part

  • Faces > Copy Face > To volume.

  • Add Flange.

  • Operation:

  • In the assembly: Clipboard> Copy / Paste.

  • In the assembly: Coincidence constraint between surfaces and Coincidence constraint between lines.


Main stages

  • Create a new part in the assembly.

  • Copy the surface chain of the Jigi part into a volume model.

  • Add flanges.

  • Copy parts.

  • Use constraints to locate the parts.





Starting point

In the past, an assembly has been created in which the jig has been modeled.

  • Continue doing this exercise in the previous exercise model.

  • If you have not yet modeled a jig, see the instructions from the previous exercise.

  • You can also download a model from the end of the previous exercise.

Create a new part in the assembly

  • Right-click function: New > Part.

    • Enter the label (which is also the name of the model and by default will be the name of the drawing).

    • Enter the archive information by clicking Arc.Data.

    • Accept (or create a new) project, where the model will be saved.

    • OK.

Copy the surface of the jig into a sheet metal part.

  • Right-click function: Faces > Copy Face.

  • Select TAN in the upper left corner of the desktop, ie the selection of the tangential surface chain. 

  • Click a face.The program searches for tangential surfaces.

  • OK2.png

    • Dialog Copy Surface opens.

  • Leave the value: 0 (the surface is copied exactly to the location of the old surface), shown in the figure.

  • Click: Out, shown in the figure 1).

  • Select: To Volume, shown in the figure 2).

  • OK, shown in the figure 3).Dialog Tangential Offset opens.

  • Enter the sheet metal thickness value: 2, shown in the figure 4).

  • Click: Out, shown in the figure 5).The sheet metal comes out of the surface.

  • Select: Change to sheet metal part, shown in the figure 6).This changes the properties of the part to sheet metal.

  • OK, shown in the figure 7).

Add flanges (mounting edges) to the part

  • Click to the two lines on the outside edge of the sheet metal.

  • Right-click function: Add Flange.

  • Enter the value:

    • Radius: 2

    • Angle: 90 or 100 (The value 100 found by experiment).

    • Length: 40

The program suggests an angle of 90. You can accept it to see if the part looks valid.

  • Turn the projection in the direction: Left View.

  • If necessary, edit the Flange feature (for example, by double-clicking it on the feature tree) and try other values.

Return from part to the assembly:

  • OK2.png (This function saves the part automatically.)




Create another sheet metal part in the same way

  • Right-click function: New > Part.

  • Right-click function: Faces > Copy Face.

  • Right-click function: Add Flange.In this part, the angle 96.4° angle looked good.


Return from part to the assembly:

  • OK2.png (This function saves the part automatically.)

Complete the assembly by copying the parts

  • Click a part.

  • Right-click function: Clipboard > Copy.

  • Right-click function: Clipboard > Paste.

  • Before positioning, turn the part 90 ° twice around the blue axis.

Use the Conincident constraint to locate the parts

Add three Conincident constraint between each part and the jig.

  • Two pairs of faces.

  • One pair of lines.

Hide the jig

You should create a new configuration in the assembly where the JIGI part is visible and hide it in the O: Defauld configuration.

  • Click Configurations. (From the feature tree)

  • Right-click function: Add Configurations.

  • Select this new configuration: 1: Configuration 1.

  • Right-click function: Properties.

    • Enter a new name: Eg Jig.

    • OK.


  • Activate the configuration: 0: Default (Either double-click or Right-click function).

  • Click the JIG part.

  • Right-click function: Hiding > Hide.

  • Click the configuration: 1: Jig.

  • Right-click function: Update Hiding State.

Create drawings for parts

  • Take each part in turn for editing.

  • Enter or select a raw material for the parts (See exercise 2: Box) 

  • Create a drawing.

    • Click the Drawings in the feature tree.

    • Right-click function: New Drawing.

    • Select scale (1: 5 to fit geometry on A3 form).

    • Select projections: Front, top, left and Flatten sheet.


Save the dawing

  • File > Save or click Disketti.png or press Näppäin_Ctrl.png Nappain_S.png

  • Remove the drawing from the desktop.

  • Return from part to the assembly

    • OK2.png

Create a drawing for the assembly model

  • Click the Drawings in the feature tree.

  • Right-click function: New Drawing.

  • Select projections, such as front, top, left, and ISO, -45 front right.

  • Select scale (1:5 to fit geometry on A3 sheet).

  • Add part numbers: Drawing> Machanical > Parts list> Part number.

    • Number > Number

    • Exit the dialog.

    • OK.

    • Click the part (1 and 2) and the location of the part number ball.
