Commonly asked Pro-e Interview questions...Part 3

1. Name six common assumptions the sketcher will make ?                                                                Six common assumption 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, tang-ency  symmetry, parallel and perpendicular lines. 
2. What is the difference between One Side and Both Sides in extrusion?                                                          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?                                                                                Modify > pick the feature > pick the dimension > enter the new value > select regenerate. 
4. What is the model tree?                                                                                                                        The model tree is a graphical representation of the features and/or components in the model. 
5. Define "Parametric Feature Based Modeling" ?                                                                      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’?                                                                                             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 ?                                                                                                            Five uses of datum plane are as follows -                                                                                                Sketching plane                                                                                                                                       reference plane                                                                                                                                             dimension and alignment references                                                                                                     geometric tolerancing                                                                                                                                    creating cross sections. 
8. List three uses of datum axes ?                                                                                                                 Three uses of datum axes are as follow -                                                                                 Dimension and alignment references,                                                                                              center lines on drawings,                                                                                                                     geometric tolerancing and coaxial hole.  
9. List two uses of a datum coordinate system ?                                                                                      Datum coordinate system is used While exporting to IGES, STL and STP files  
10. Name a feature that can both add and remove material?                                                                       Rounds and champers are the features which can both add or remove the material.
