CAD Flashcards
KEY WORDS FOR EXTRUDE COMMAND?
on highlighted profile extrude (ADD OR SUBRTACT) Xmm
STEPS FOR REVOLVE COMMAND?
Sketch the profile with all dimensions
Identify the centre axis
Revolve the profile 360° around the centre axis
STEPS FOR LOFT COMMAND?
Sketch the first profile with all dimensions
Offset a work-plane parallel to the original profile by __mm
Sketch the second profile with all dimensions
Use the loft command
STEPS FOR HILUX COMMAND?
Sketch a profile with all dimensions and a centre axis.
Use the helix command and set the pitch and the number of revolutions.
STEPS FOR EXTRUDE ALONG A PATH?
Sketch the profile with all dimensions.
On a perpendicular plane sketch the path with all dimensions.
Use the extrude along a path tool and select the profile and path.
HOW WOULD YOU CREATE ROUNDED CORNERS?
FILLET
HOW WOULD YOU HOLLOW OUT A SHAPE LEAVING A HOLD ON ONE SIDE?
SHELL
HOW WOULD YOU CREATE SLOPED EDGES?
CHAMFER
NAME ALL THE CONSTRAINT TYPES?
MATE, ALIGN, OFFSET, TANGENT, ORIENTATE, CENTER AXIS
WHAT CONSTRAINT WOULD BE USED TO STICK TO SURFACES TOGETHER?
MATE
WHAT KIND OF ARRAY WOULD BE USED TO CREATE A SQUARE PATTERN OF HOLES AS SHOWN BELOW
0000
0000
0000
BOX ARRAY
WHAT IS A MODDELING TREE?
A modelling tree is a hierarchal list that shows how you have created your CAD model. It is useful because it allows designers to edit sketches, dimensions or other aspects of their model without having to start again.
WHAT IS TOP DOWN MODELLING?
Top down methods allow a designer to control the design in situ - within one assembly document
BOTTOM-UP MODELLING?
This modelling process is where components are modelled individually then assembled together using constraints.
NAME THE THREE TYPES OF ARRAY?
LINEAR, BOX, RADIAL.
WHAT FILES TYPES CAN BE USED FOR CAD MODELS?
STEP
WHAT IS THE PURPOSE OF A DXF FILE TYPE?
VECTOR GRAPHIC, GOOD FOR 2D DRAWINGS.
WHAT ARE THE BENEFITS TO A CAD LIBRARY?
ALL PARTS ARE EXACTLY THE SAME SIZE, QUICKER THAN REMAKING EVERY TIME
ADVANTAGES TO CAD ILLUSTRATION?
BETTER COMMUNICATES DESIGNS TO NON GRAPHICS SPECIALISTS
EASIER TO MAKE THAN TRADITIONAL ILLUSTRATION METHODS
ADVANTAGES OF CADD ILLUSTRATION WHEN PRESENTING TO CLIENTS
Creates photo realistic images of how products or buildings will look.
Creates a realistic representation of materials used in the product.
Product or building can be shown in its proposed environment.
Realistic representations of different lighting conditions, for example daytime and nighttime.
