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)
