Q001) What is Creo Parametric?

Creo is a CAD software used to create 3D models and 2D drawings. Also, Creo is the first-ever feature-based solid modeling CAD software in the market.

______________________________________________________________

Q002) How do you configure Creo Parametric?

We configure Creo parametric by entering appropriate values in the configuration editor, config.pro

For example, by changing the value of "pro_unit_length" to "unit_mm", we can set the default unit of length of any new object to mm. By default, the unit of length measurement in Creo parametric will be an inch.

______________________________________________________________

Q003) What is a working directory in Creo Parametric?

The working directory is a folder designated to store Creo parametric files.

For example, suppose you are designing a chassis of a car. In that case, it s always a good practice to store all files related to the chassis in a specific folder. So, In Creo Parametric, we can designate the working directory by clicking on File, Options, Environment and then Browse the working directory, then Select Working Directory.

Q004) How do you set the working directory in Creo Parametric?

In Creo Parametric, we can designate the working directory by clicking on File, Options, Environment, Browse the working directory, and then Select Working Directory.

______________________________________________________________

Q005) What is a Trail File in Creo parametric?

A Trail file is an editable text file.

______________________________________________________________

Q006) What's the function of Trail File in Creo Parametric?

A Trail file records all the menu choices, dialog-box choices, selections, and keyboard entries of a working session

______________________________________________________________

Q007) What's the use of Trail File in Creo Parametric?

A Trail file helps the user to reconstruct a previous Creo Parametric session, especially when the Creo Parametric session unexpectedly terminates.

______________________________________________________________

Q008) What's "unexpected termination" in Creo Parametric?

If the Creo Parametric window closes abruptly, without giving an option for the user to save the data, it's called unexpected termination.

______________________________________________________________

Q009) Where do you find the Trail File?

The Trail file will be stored in the "Working Directory."

______________________________________________________________

Q010) How to run a Trail File?

It's always better to make a copy of the trail file and then rename the trail file using windows explorer. Also, we need to remove the version number.

To run the Trail file, click on “File,” “Manage Session,” and then “Play Trail File.” Next, select the Trail File and then click Open.

Q011) How do you retrieve the data if the Creo Parametric window closes abruptly?

We can retrieve the data by running the Trail File.

______________________________________________________________

Q012) What is a "version number" in Creo Parametric?

To understand the version number, let's take an example of a user working on a part model with the name "plate."

When you save the plate. The plate gets saved with the name: “plate.prt.1”

If you save the plate again, a new version of the plate is created with the name: “plate.prt.2”

If you save the plate again, a new version of the plate is created with the name: “plate.prt.3”

To summarize, a new version of the file is created whenever you save a Creo Parametric File.

This .1, .2, .3 extensions are called version numbers

______________________________________________________________

Q013) how do you display the version number of a file in Creo Parametric?

Displaying the version number of a Creo Parametric file can be done only from Windows Explorer.

On the Windows Explorer window, click on the "View" tab and then click on "Options," and then select "Change Folder and Search Options." Then under the "View" tab, uncheck the "Hide extensions for known file types."

______________________________________________________________

Q014) What are the file extension of a part assembly and drawing files in Creo Parametric?

.prt is the file extension of a part file

.asm is the file extension of an assembly file.

.drw is the file extension of a drawing file

______________________________________________________________

Q015) What is an External Reference?

A feature on one part referencing a feature in another part is called an external reference. External references are created while editing a part in an assembly mode. It is not advised to create external references in the final model; However, external references can be used to capture design intent while designing. External references can be deleted once the design is finalized.

______________________________________________________________

Q016) What is a Quilt?

A quilt is a “patchwork” of connected non-solid surfaces.

______________________________________________________________

Q017) What is a Freeform Surface?

The freeform surface is a command used to create or modify a surface using control curves in 2 directions.

The advantage of the freeform surface command is that the surface can be modified interactively in real time by dragging the grid points formed by the intersecting control curves in 2 directions. The freeform surface changes its shape based on the position of the grid points in real-time.

______________________________________________________________

Q018) How to enable a Freefrom Surface?

To enable a Freeform surface, set the value of “enable_obsoleted_features” to “yes” in config.pro

______________________________________________________________

Q019) Give some examples of engineering features.

Holes, Rounds, Chamfers, Drafts, Shell, Ribs, and Cosmetic threads are a few examples of engineering features.

______________________________________________________________

Q020) Give some examples of datum features.

Datum planes, Datum Axes, Datum Points, Datum Curves, and Coordinate systems are a few examples of datum features.
