What is the difference between " Move" and "Move Text" ? 100. Name the four types of tolerance formats available in Pro/Engineer? 101. Which of the tolerance formats should you not use? 102. What is a drawing symbol? 103. Can a drawing reference more than one assembly? 104. Can a Pro/Engineer drawing be opened in AutoCAD? 105. Can the units of a part be changed without changing the size of the part?

Answers: 1. Object reference is a data management term that has to do with the way one object references another. Geometric associativity has to do with how a parts geometry can be changed from the part or drawing. 2. Sketches - .sec, Parts- .prt, Assemblies- .asm, Drawings- .drw 3. You should always create a new part or assembly using the copy from option in the new dialog box and copy a start part. This ensures the proper layer setup, saved views, datum planes, parameters, etc. 4. The config.pro file contains configuration options which control the behavior of Pro/ENGINEER. This file also contains user macros which are called map keys. 5. The trail file is a record of every menu pick and screen pick and keyboard input during an entire session of pro/engineer. This file can be retrieved and edited and replayed to retrieve work lost during an unexpected failure of a session. 6. 'Store back' refers to the behavior in which an object is stored back to the directory from where it was opened not necessarily the current working directory. 7. File erase removes the object from the ram of the computer and file delete removes the object from the disk or hard drive of the computer. 8. File save stores the object in the directory where it was opened from and file backup copies the object to the specified directory using the same name. 9. After performing a file save as command the current object is not a new object it is the old object. 10. No. 21. 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. 22. One-side extrudes only one specified direction from the sketching plane. Both sides extrudes both sides of the sketching planes. 23. Modify > pick the feature > pick the dimension > enter the new value > select regenerate. 24. The model tree is a graphical representation of the features and/or components in the model. 25. 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. 26. 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. 27. Five uses of datam plane are as follows - Sketching plane, reference plane, dimension and alignment references, geometric tolerancing, creating cross sections. 28. Three uses of datum axes are as follow - Dimension and alignment references, centerlines on drawings, geometric tolerancing, coaxial hole. 29. Datum coordinate systme is used While exporting to iges and stl. 30. Rounds and chamfers are the features which can both add or remove the material.

91. When the feature regenerates. 92. A constraint relation is used to put limits on parameters (usually dimensions) based design intent and/or manufacturing limitations. 93. Integer, real number, string, yes_no. 94. Logic statements are a series of relations that test parameter values and performs actions based on the results of the test. 95. You should comment relations so that other users can understand what you are trying to accomplish with the relations. 96. Sorts the relations in case of circular references within the relations. 97. Yes. 98. Use ampersand and then the parameter name (&material). 99. Move allows you to move the selected item anywhere. Move text allows you to move the selected item only parallel to the elbow. 100. Nominal (no tolerance shown), plus/minus, plus/minus symmetric, limits. 101. Plus/minus (because manufacturing people want the model at the mean size not the nominal size). 102. A symbol is a collection of draft entities that are stored together for reuse on other drawings. 103. Yes. 104. No. (Yes, but only after translation to dxf or iges or dwg). 105. Yes.
