connecting things to things
tolerance
used to give a range for error
why
It is too hard to get the exact measurements consistently without error
types
Bilateral Tolerance
Unilateral Tolerance
Limit Tolerance
uni: one
only one side is allowed to have an error
one side has its margin for error
the other side has its own margin for error
both sides share a margin for error
Bi: two
tolerance=upper limit-lower limit
assemble model
how to add tolerance into drawings
create the model
create the drawings
double click the dimension
save work
joints that we used today
revolute joint
spin in one point
rigid joint
connected pieces cant move
explode the model
animation manual explosion
dont overlap too much
Draw using animation
place the image
save draft
add bubbles
add table
Finish
Clearance Fit
Interference Fit
allows parts to move
hard to move parts
to see parts cost and what materials to use
dimensioning
parallel
most of the dimensions are taken from one side
superimposed running
simplified parallel
chain
maximum shaft is smaller than minimum hole
maximum hole is smaller than minimum shaft
like parallel but everything is side by side
combined
parallel and chain together
small features
arrows on the outside
use manual transform
remember the lines
multiple features
N*Dimension
radius
R(number)
