I. Introduction

Advanced Assembly techniques allow the engineer to better utilize the Pro/ENGINEER tool when designing large and complex assemblies. In this tutorial, you will learn how to create and use layers, simplified reps, and component display functionality’s in order to optimize how your parts and assemblies are shown in a design environment. All three of these techniques can be used to aid the engineer in working more efficiently when the assemblies being used are large. Mastering the basic concepts introduced in the first few FroTime Advanced Assembly Tutorials is very important when moving on to the more complex functionality that is covered in the later tutorials.

II. Tutorial Lesson – Creating and Displaying Layers

** Layers in Pro/Engineer provide you with the ability to organize model objects into groups so that you can perform specific operations on them collectively. ** Terms to Know Blanked Layers – Layers that are removed from the screen. Shown Layers – Layers that are present on the screen. Isolated Layers – Layers that remain on the screen while all other layers are removed. ** To begin, open the existing part called “gear_ft”. ** • FILE menu: #File, #Open, Name:<gear_ft.prt>, #Open ** Turn on all datum planes, axes and coordinate systems by using the side menu bar or in the environmental settings. Datums can be turned on either by selecting the datum icons on the menu display or going into the Environment from the Utilities menu. **


AA1_WF_01 Page: 6

** The display should be something similar to the image below. **

** We will now create a layer to capture some of the datum planes that we can isolate and black from view. ** • Show menu: #Layer Tree…


AA1_WF_01 Page: 7

** The layers window should appear similar to the following image. **

** Create a layer called “teeth_dtm”. ** • EDIT menu: #New Layer… ** When you create a new layer the Layer Properties dialog will open. This will allow you to give a name for the layer and add items to it as well. **

Layers are now located within the Model Tree dialog


AA1_WF_01 Page: 8

** We will now add all datum planes to the layer “teeth_dtm” that was just created. ** • RULES menu: #Edit Rules… ** Now fill out the search criteria as shown in the following image. This will select all the datum planes for the component and add it to the layer that is being created. Then click on the Add New button to add these search criteria as a rule. **


AA1_WF_01 Page: 9

** Click on the Find Now button to search the component for all the datum planes. This will return all the datum planes and display them at the bottom of the Search Tool. **


AA1_WF_01 Page: 10

** To accept all these objects select the OK button. Once you are done the rule criteria will be displayed in the layer properties window. Select OK when you are done. **

** We will now blank the “teeth_dtm” layer, which in turn will blank all the datum planes that were captured within that layer. ** ** Make sure that the “teeth_dtm” layer that was just created is the only layer that is highlighted. **


AA1_WF_01 Page: 11

** Right click on the “teeth_dtm” layer and select Blank Layer from the fly out menu. Then repaint the screen to see the result. It should appear as the following image. **

** We will now remove the default datum planes of the “teeth_dtm” layer so that they will remain visible while the remaining datum planes are blanked. ** ** Make sure that “teeth_dtm” is highlighted. Right click on the layer and select the Layer Properties button. Now when the dialog box appears select the option labeled Exclude… from the bottom of the dialog box. Then select the first three datum planes as shown in the following image. **


AA1_WF_01 Page: 12

** Now select OK and the three default datum planes should now appear in the model window. The final part display should have the default datum planes visible as shown below. **

III. Tutorial Lesson – Creating Simplified Reps ** A Simplified Representation (simplified rep) is a tool that is used to manage large assemblies in Pro/ENGINEER. Simplified reps control which objects of a users assembly are retrieved into a Pro/ENGINEER session and displayed. Multiple simplified reps for a single assembly or part can be created. Each simplified rep can correspond to a specific area of the assembly that needs to be worked on. Using simplified reps decreases regeneration, retrieval, and repaint times and makes working with large assemblies much more efficient. ** Terms To Know Master Representation – The Master Representation (Master Rep) contains the entire detailed model. It is the basis for all simplified reps. All assembly functions are applied to the Master Rep and are reflected in all other simplified reps. Open Rep – Instructs the system to load into memory and display only the components in the specified rep. Set – Sets the representation that is specified by the user as the current representation. Graphics Rep – Represents all geometry as “wireframe” only, allowing for fast retrieval times. This will open up the model but it cannot be referenced by any other part of the assembly (cannot be assembled to). Geometry Rep – Represents accurately all geometry as solid, requiring for slower retrieval times as well as memory. Will load all geometry and allow the surfaces and edges to be used as references. ** To begin, we will open an existing assembly called “motor_assy”. ** • File menu: #File, #Open, Name:<motor_assy.asm>, #Open ** Make sure to turn off all datum planes so that the assembly model will be easier to see. The motor assembly should look like the following image. **


AA1_WF_01 Page: 14

** We will now create a Simplified Rep called “no_cover” that will display the assembly without the front and back covers. ** • VIEW menu: #View Manager


AA1_WF_01 Page: 15

** To add components to be removed select Edit -> Redefine, by default the Exclude components is used, which means any component you select will be removed from the assembly. If you click on Include it would only show the selected objects and all others would be automatically excluded. **

** Select both motor covers and the mounting screws that holds them to the motor housing using the model tree or by selecting directly from the graphics screen, or by selecting from the model tree. All objects that will be excluded with show as such in the added column in the model tree as shown. **

View Manager is a new addition, here you can

find: • Simplified Reps • Explode • View Orientation • Component Display

(Style)


AA1_WF_01 Page: 16

** To preview the model you can do so by selecting the button then select the button. The results should look like the following image. **


AA1_WF_01 Page: 17

** Notice that all the selected items have been removed from the assembly model. Even though the items are not displayed, they are still a part of the assembly as you can see by selecting the items in the model tree and highlighting the models on the screen. **


AA1_WF_01 Page: 18

** We will now create a Simplified Rep named “graphics_motor” which will contain a Graphics Rep of all the components with the exception of the motor housing. ** • View menu: #View Manager… ** Before you create a new simplified rep be sure to set the current rep to the Master Rep. Do this by selecting the Master Rep and right click on it selecting the Set option. Now select the New option and enter in the name of ”graphics_motor”. ** ** Select Edit -> Redefine then click on the Include tab. Choose the Graphics Rep option then select the first cover.prt from the model tree hold the shift key and select the core.prt, this will select all components but the motor.prt. Select the check the check mark to finish. **


AA1_WF_01 Page: 19

** The results should look like what is shown below. **

** Now that we have made a few Simplified Reps, we can now switch between the created reps and Master Rep by using the “Open Rep” and “Set” commands. ** ** Save the assembly motor_assy.asm and close the window. ** ** Open the “motor_assy” assembly in the “no_cover” representation. ** • FILE menu: #Open, Name: <motor_assy.asm>, #Open Rep


AA1_WF_01 Page: 20

• Open Rep menu: Name: <NO_COVER>, #OK ** This should take you back to the”no_cover” representation. ** ** Now we will switch between the “graphics_motor” and “master” representations. ** • VIEW menu: #View Manager…, right click <GRAPHICS_MOTOR>, #Set,

#Close. • VIEW menu: #View Manager…, right click <Master Rep>, #Set, #Close. ** Go ahead and practice creating more simplified reps using the techniques described above. **


AA1_WF_01 Page: 21

IV. Tutorial Lesson – Component Display ** Component Display allows for the components within the assembly to be displayed in various visual stages in order to provide for a more clear representation when viewing the assembly model. ** Terms To Know Set– Sets the display settings that are specified by the user as the current display. Blank – The component is removed from the display. Wireframe – The component is displayed only in the wireframe form. Hidden line – The component is displayed only in the hidden line form. ** To begin, we will open an existing assembly called “motor_assy”. ** • FILE menu: #File, #Open, Name:<motor_assy.asm>, #Open ** Make sure to turn off all datum planes so that the assembly model will be easier to see. The motor assembly should look like the image below. **


AA1_WF_01 Page: 22

** We will now create a display called “wire_motor” which will show some of the components in different display settings. ** • VIEW menu: #View Manager…, select Style tab. ** The component display is not integrated into the View Manager and can be manipulated in the same ways as the simplified reps are. ** • STYLE tab: #New, Name: <wire_motor>, #Edit,

#Redefine. • BLANK tab: #Blank ** Select the front motor cover. ** • SHOW tab: #Wireframe ** Select the gear. ** • SHOW tab: #Hidden Line ** Select the motor housing. ** • VIEW MANAGER dialog: select green check mark, #Close ** The resultant display should look similar to the following image. **


AA1_WF_01 Page: 23

** Now that a display rep has been created, it is possible to switch between the master rep and the created rep. ** ** Go ahead and practice creating more display reps using the techniques described above. ** ** One thing to notice is when you have a component display set, go ahead and switch between your default views using the display icons. **

** Notice that the components that have a component display stay the same no mater what your display icon is set to. **
