which phrase best describes what a “parameter” is in Creo?

a variable

which phrase best describes what a “relation” is in Creo?

an equation

If there are two pre-existing parameters, “HEIGHT” and “WIDTH” and a new parameter “LEGNTH” is two times the sum of HEIGHT and WIDTH, what is the proper syntax to be used in the relations definition box?

LEGNTH=(HEIGHT+WIDTH)*2

Which of the following describes what a “trajectory” is in a sweep feature?

the path that sweep follows

which of the following describes what a “profile” is in a sweep feature

the path that defines the sweeps cross section

Which of the following is a valid selection for a sweep trajectory?

all of the above

Sweep profiles can be made as a section internal to the feature or an external sketch

false

while selecting multiple segments of an edge chain to use a single trajectory for a sweep, the _____ key should be held

shift

to select multiple chains for a multi-trajectory (variable section) sweep, the ____ key should be held

control

what type of blend is this?

rotational blend

what type of blend is this?

swept blend

what type of blend is this?

blend

profiles for blend sections must be created as internal features

false

If blend profiles have different numbers of vertices what can be done to ensure blend feature success

• add rounds to smooth out the sharp corners

• observe which section has the highest number of vertices and divide all the other sections so that their vertex count matches that observed max count

• delete extra vertices from the profile sketches

• in the sections with fewer vertices, designate one (or more) vertex as a “blend vertex” so that multiple points from neighboring sections will blend into this single point

• observe which section has the highest number of vertices and divide all the other sections so that their vertex count matches that observed max count

• in the sections with fewer vertices, designate one (or more) vertex as a “blend vertex” so that multiple points from neighboring sections will blend into this single point

For internal section sketches in a blend, what should be done to change the start point of a section?

Edit the section sketch> left click desired start point vertex> long right click> feature tools> start point

For external section sketches in a blend, what should be done to change the start point of a section?

In the blend feature, select the section, locate the white circular handle for the start point, and click+drag to the desired location.

Surface modeling techniques are capable of producing the same geometry that solid modeling techniques can create

true

which of the following commands turn surface bodies into solid bodies?

• merge

• thicken

• solidify

• fill

thicken

solidify

a solidify feature can be created from multiple different quilts that intersect each other

false
