CATIA V5- QUESTIONS & ANSWERS from Caddskills Vol 1
Computer
Aided Three Dimensional Interactive Application.
2. What
is the save extension of sketcher file?
CAT
Part
3. Does
CATIA V5 work on UNIX Platform?
Yes
4. Is
it possible to increase the size of plane boundary representation &
how?
Yes,
go for Tools-Options- Infrastructure-Part structure-Display
5. Is
It Possible to directly enter in to Sketcher Workbench?
No, it is not possible to enter in to sketcher workbench directly. We
have to go for any
workbench
&form there we can enter the sketcher workbench..
6. Which
is the tool used to exit from sketcher workbench to part design Workbench?
Exit
Sketcher.
7. What
is use of construction elements?
Construction
elements assist in sketching the required profile in sketcher.
8. What
are the default units of LMT (Length, Mass and Time)
mm,
Kg, Second.
9. What
is SKETCH TOOLS in sketcher work bench & Explain the Importantance of
it?
SKETCH TOOLS in
sketcher workbench are the commands, which find very use in creating
sketches. SKETCH TOOLS are namely geometric and dimensional constraints,
construction elements/standard elements and Grid option. They play very
important role in sketching, whenever we want to constrain a sketch we use
these options and if we want to convert any element into a construction
element once again these options come into picture.
|
Yes,
with help of F3 button, but the option in Tools command must be checked to
allow
this.
11. What
is SHOW/HIDE option?
Show
mode enable us to see all the components presently opened and in Hide mode we
can hide the desired elements from the view for time being.
12. What
is the use of Cut Part by Sketch Plane?
This task shows how to make some edges visible. In other words, we are
going to
simplify
the sketch plane by hiding the portion of the material that is not needed for
sketching.
13. How
do you measure arc length?
We
can measure arc length by using MEASURE ITEM command. Sometimes we need to customize
the option for arc length if it is not checked earlier using customization in MEASURE
ITEM command.
14.What
is the meaning of true dimension?
True dimension is the dimension desired after the machining. In other
words, this is the
value
that should be attained after the machining.
15. What
do you mean by ISO-Constraints?
If
all of the degrees of freedom of geometry have been takes up by a consistent
combination of dimensions & fixed geometry,. That geometry is said to be
ISO-CONSTRAINED. Geometry that still has some degrees of freedom is said to be
UNDER constrained.
15 (b). Mention the color code of
ISO-constrained, under, and over con strained elements?
The
color code for these elements is Green, White and Magenta respectively.
16.What
for animated constraint command is used?
This
task shows how constrained sketched element reacts when we decide to vary one
constraint.
17.How
many dimensions are required to constrain the ellipse?
Three
dimensions are required namely major axis, minor axis and the distance from the
origin.
18.What
are different conic sections?
Ellipse, Hyperbola and Parabola
19.What
is RHO
value for ellipse, Parabola and hyperbola?
Parabola
has RHO values of 0.5, Ellipse has RHO value between 0 & 0.5 and Hyperbola has RHO value b/w 0.5 &
1.0.
20.What
is NURBS?
Nurbs
are the type of curves
21. How
many types of Co-ordinate systems are there?
Three
namely Cartesian, Polar and Spherical co-ordinate system.
22. What
are project 3D silhouette edges?
Project 3D silhouette edges in sketcher will shows how to create
silhouette edges to be used in as geometry or reference elements.
23. What
is use of sketch analysis?
To check whether the sketch is fully closed or not so that the sketch
can be used or not so that the sketch can be used for further operations in
part design.
24. Where
do we use axis?
Axis
is used in creating shaft (revolved) feature.
25. Can
we redefine the sketches?
Yes.
26. Can
axis be converted into line or vice versa?
We
can convert line into axis but axis cannot convert into line.
