Pro Engineer PTC Software | Interview , viva, Oral Question and Answers
1. What is the difference between object reference and geometric associativity?
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. What are the file extensions given to parts? assemblies? drawings? sketches?
Parts: .prt – Assemblies: .asm – Drawings: .drw – Sketches: .sec
3. How should you create a new part or assembly? Why?
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. What is the config.pro file used for?
The config.pro file contains configuration options which control the behavior of pro/engineer. This file also contains user macros which are called mapkeys
5. What is a trail file?
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. What does ‘store back’ mean?
‘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. What is the difference between File, Erase and File, Delete?
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. What is the difference between File, Save and File, Backup?
. 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, what is the current object?
After performing a file save as command the current object is not a new object it is the old object
10. If I use Window, Close without saving my model, have I lost my work?
11. If I use File, Erase without saving my model, have I lost my work?
12. What is a feature?
A feature is a geometric definition of part of the model.
13. (True or False) All features have parents. Explain.
True, with the exception of the three default datum planes. All features reference other features for their definition thus creating parent/child relationships
14. (True or False) All features have children. Explain.
False. Example, rounds and chamfers should not have children.
15. (True or False) Parent child relationships are bad. Explain
. False. Parent/child relationships are bad if you are not aware of how they are created.
16. Can parent child relationships be broken?
Yes, using Redefine or Reroute.
17. What is the mouse button sequence to query select an object that is under another object?
Right, left to pick, right as many times as you need to to get the thing you want, middle to except the thing you want, middle again for done select.
18. What is a reference plane? What does #Default do?
The reference plane gives the sketching plane it’s orientation. Using default, the system picks the reference plane for you and does not create a parent/child relationship.
19. What does a sketch point do?
A sketch point is used as a construction entity to help constrain a sketch.
20. What do a construction circle and a sketch centerline do?
A construction circle and a sketched center line are used to help define your design intent.
21. Name six common assumptions the sketcher will make.
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. What is the difference between #One Side and #Both Sides?
One-side extrudes only one specified direction from the sketching plane. Both sides extrudes both sides of the sketching planes.
23. How do you change dimensions of a feature?
Modify, pick the feature, pick the dimension, enter the new value, pick regenerate.
25. 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.
26. What is different about 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.
27. List five uses for datum planes.
Sketching plane, reference plane, dimension and alignment references, geometric tolerancing, creating cross sections.
28. List three uses for datum axes.
Dimension and alignment references, centerlines on drawings, geometric tolerancing, coaxial hole.
29. List two uses for a datum coordinate system.
When exporting to iges and stl.
30. Name a feature that can both add and remove material.
. Rounds and chamfers
