CAD/Tech Flashcards
Instead of extrude or revolve you must say…
Subtraction
What are the two joint and constraint terms
allign and mate
Three reasons why a 3D model is better than physical
Easier to share, no material waste, easier to edit
A/F means what
Across flat -
what’s the little circle and square symbol together mean that has a centre line through it horizontally
3rd angle projection
the CAD control names to create the basic shapes
rectangle, circle, arc, chamfer, fillet, line
whats chamfer used for
curves corners
the constraint mate connects what?
wall faces like a book closing
the constraint align connects what?
the roofs side by side like brick formation
the constraint center axis connects what
the inside wall parts like the ring wall of top of Lego piece
what is the cad drawing tool for cutting something in half?
trim
what is the cad tool for enlarging something?
scale
why would icons be used on mobile apps instead of writing?
universally understood
eye catching
familiar to users
not specific to a language
how would remote working reduce the environmental impact?
reduces the need to travel
advantage of 3D printing when creating a new product?
Digital models can be made physical
to test various aspects (how it looks,
how it feels, etc).
Provides a tactile, physical product
what is the cad buttons for making an object have the shiny?
Stage 2 – Material added
Stage 3 – Lights added
what is the cad button command for making an object have a tint?
add white
circle and oval command
circle and elipsis
make a line longer command
extend
have one object and make copies go in one circle
radial array
have one object and make copies go vertical
linear array
have an object and make other go in box shape
box array
make a component bigger or smaller and to turn something around command
zoom/scale
rotate
remember the offset and mirror command
…
What is cloud based computing and its pros
an online server to store data.
enifits:Lots of people can work on the same files the same time
People are able to access files anywhere in the world
We can use online software to edit files out with the office
What is cloud storage?
Place to store and access online files and data
Allows employees the flexibility to work from home, example of a cloud storage is one drive
What is the digital rights management?
Allows creators (graphic designers) to prevent the unauthorised use of their content
Helps companies control access to confidential info
Top down modelling and its benifits
Method of creating and designing the geometry within an assembly
Everything is created in the context of an assembly
-
dimensions can be projected to ensue there’s an exact fir between components
change one components and it will dynamically change the other ones
Bottom up modelling
Different parts of a system are designed and developed separately then are all connected to create a single unit
Modelling tree/hierarchy
Tree structure or diagram or model used to represent the hierarchy nature of a structure in a graphical form
Modelling plan
Clear, precise, well illustrated modelling plan
Benefits of using 3D CAD model for manufacturing
3D models can be used to directly manufacturing
Can be used to show how complex items are assembled
Benefits of using 3D CAD model for advertising
Gives realistic representation of what final product looks like
3D models can be animated
Two benefits of using the CAD library
Includes common objects needed when designing housing and office buildings
Has good quality objects easily accessible that’s easy to use, saves time
Explain the term sub‑assembly
group of components that are part of a larger assembly, but which can be installed or removed separately
Two apps used for graph comm
Auto desk inventor
Photoshop
Why can a 2D CAD drawing be produced more quickly than a 3D model of the control panel?
Cheaper
More simple to create animations
what are the benifits of a 3D model over a 2D drawing?
shows depth and sizes compared to each other
what is the difference between the major and minor axis of an ellipse?
major axis is the widest part of an ellipse
-minor is the thinnest part
flatbed scanner and what its used for?
used to scan images into JPEGs
advantages and disadvantages of using stock images
positive:
no purchase cost of buying stock images
will show quality of their own work
can get the exact photos they need
-
negative:
wont get the exact photo that you need
-cost of purchasing the rights to the photo
disadvantage of cloud based computing
risk of being hacked
no signal or internet means no access
What does the command suppress do
When using a pattern like array opif you do not want the whole part to be copied and arrayed, suppress stops particular parts from being copied
In DTP what is the handle
The small corner bit you press to move objects in DTP
What’s the chunk of writing on a magazine called (not referring to placement)
Extended text
Client requested an outdoor workshop is constructed. Why would designer use the CAD library when creating the drawings
library would contain all commonly used symbols meaning they would be standardised or commonly understood
The library can be used by all CAD technicians in the company meaning consistency across all drawings
What’s the effect of placeholder text
Speeds up the process of creating layouts as the graphic artist does not need to manually type the text required
Allows the graphic artist to consider placement of text without being distracted by the readable content of a page
example is lorum ipsum
