5. What is a trail file?

6. What is the meaning of "store back"?

7. What is the difference between File -> Erase and File -> Delete?

9. After performing a File, Save As, what is the current object?

10. If I use Window in Pro/Engineer and Close without saving my model, have I lost my work?

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...
