Pro/ENGINEER Interview Questions with Answers # 6

1. Name six common assumptions the sketcher will make.

Ans: Six common assupmption the sketcher will make are as follows - Horizontal and vertical, equal length lines, equal radius or diameter, co-linearity, 90 and 180 degree arcs, points on the same horizontal or vertical, points on other entities, tangency, symmetry, parallel and perpendicular lines.

2. What is the difference between One Side and Both Sides in extrusion?

Ans: One-side extrudes only one specified direction from the sketching plane. Both sides extrudes both sides of the sketching planes.

3. How do you change dimensions of a feature?

Ans: Modify > pick the feature > pick the dimension > enter the new value > select regenerate.

4. What is the model tree?

Ans: The model tree is a graphical representation of the features and/or components in the model.

5. Define "Parametric Feature Based Modeling" ?

Ans: Parametric means driven by parameters. Feature based means you define a series of instructions (features) to tell the system your design intent. Modeling means creating computer images coupled with geometric information defining a part or assembly.

6. What is datum planes created ‘on the fly’?

Ans: The datum plane created on the fly means it was created when you were in the middle of creating something else and it goes away after the thing you really wanted was created. These are created using the 'make datum' command.

7. List five uses of datum planes.

Ans:  Five uses of datam plane are as follows - Sketching plane, reference plane, dimension and alignment references, geometric tolerancing, creating cross sections.

8. List three uses of datum axes.

Ans: Three uses of datum axes are as follow - Dimension and alignment references, centerlines on drawings, geometric tolerancing, coaxial hole.

9. List two uses of a datum coordinate system.

Ans: Datum coordinate systme is used While exporting to iges and stl.

10. Name a feature that can both add and remove material.

Ans: Rounds and chamfers are the features which can both add or remove the material.

Pro/ENGINEER Interview Questions with Answers # 5

26 Where does Pro/ENGINEER save part files that are assembled from a directory different than the current working directory?

Ans : By default, Pro/ENGINEER will store objects that are assembled from other directories back to the directory of origin. If the user does not have write access to the directory, Pro/ENGINEER will not store the objects in the current working directory, unless specific config.pro options have been set. The config.pro options "override_store_back" and "save_object_in_current" allow greater control over this type of situation.

27 What happens during storage of an assembly if its dependent part files are located in a write-protected directory?

Ans : By default, Pro/ENGINEER will only store modified objects and will always store objects back to the directory from which they were retrieved. Therefore, if a part from a write protected directory has been modified and File, Save is selected, Pro/ENGINEER will not be able to save the object unless the config.pro options "override_store_back" and "save_object_in_current" are utilized.

28 Why can't an assembly be retrieved after clearing it from memory or after starting a new session of Pro/ENGINEER?

During assembly creation, it is possible to add components to the assembly that are located in directories other than the current working directory. When the assembly is saved, the assembly file is saved to the current working directory while modified components are saved back to the directories of origin. If the assembly is cleared from workstation memory by either exiting Pro/ENGINEER or by selecting File, Erase, and selecting all the objects in the ERASE dialog box and then retrieved, it is possible that Pro/ENGINEER will not be able to locate certain components. The config.pro option "search_path" can be used to specify directories which Pro/ENGINEER will search for objects. The config.pro file must contain a separate "search_path" option for each directory to be searched. Refer to the Configuration Options section of the Pro/HELP for details.

29 How does File, Save As function in Assembly mode?

In Assembly mode, the File, Save As functionality allows any or all members of the assembly to be copied.

By default, after selecting File, Save As, a dialog box will appear with the name of the assembly to be copied specified next to Model Name. The new assembly name is specified on the next line (New Name). After selecting OK, a check mark can then be placed next to each assembly component to be copied or Include all subcomponents can be selected to copy all assembly components.

If a check mark is placed next to any of the components or if Include all subcomponents is selected, Pro/TABLE will be displayed where new component names can be specified in the cell adjacent to the original.

If OK is selected without selecting a component or Include all subcomponents, Pro/ENGINEER will create only a copy of the assembly which references the original components.

The config.pro option "model_rename_template" is used to create a user defined renaming scheme.

Refer to the Configuration Options section of the Pro/HELP for further information.

30 Why do parts intersected by assembly features require renaming before they can be stored?

Ans : Assembly features which intersect assembly components alter the geometrical intent of the original object. When the assembly is in session, the component exists in memory in two different states. When Pro/ENGINEER tries to save the assembly, it is unclear which state of the component is to be saved. Pro/ENGINEER will prompt the user to save the object with a new name. This will create a copy of the object containing the geometric result of the assembly feature.

31 What does the config.pro option "override_store_back" do?

If the config.pro option "override_store_back" is set to "yes", Pro/ENGINEER will save objects retrieved from other directories to the current working directory;

If "override_store_back" is set to "no", which is the default, objects will be saved in the directory of origin. If the option is set to "no" and the user does not have write access to the directory of origin, Pro/ENGINEER utilizes the config.pro option "save_object_in_current".

32 What does the config.pro option "save_object_in_current" do?

When the config.pro option "save_object_in_current" is set to "yes", Pro/ENGINEER will save objects to the current working directory if the user does not have write access to the directory from which the object was originally retrieved. If the option is set to "no", Pro/ENGINEER will not save the object at all. This option should be used in conjunction with the config.pro option "override_store_back".

33 What is the preferred method to make a copy of an assembly?

The File, Save As functionality is the best way of copying assemblies.

34 What is the preferred method to rename assembly components?

The following procedure should be used to rename assembly components:

Retrieve the assembly which contains the components to be renamed

In a sub-window retrieve the component to be renamed

With the component active, select File, Rename and enter the new component name

Select Window, Activate and pick in the window containing the assembly

Regenerate the assembly

Select File, Save to save the assembly which contains a reference to the new component name.

35 what is the preferred method to rename a drawing?

The File, Rename functionality should be utilized to rename a drawing
