Cnc And Cad Print Reading And Drafting

CNC And CAD - Print Reading And Drafting
When I​ went through college I​ learned how to​ read prints and draft .​
We had a​ bag of​ physical tools that we purchased and hauled around campus .​
T-Squares, French Curves, compasses, pencils and erasers filled this bag .​
Then you had a​ pad of​ drafting paper and a​ drafting desk .​
You would pin or​ tape the paper down and begin drawing or​ drafting.
Drafting paper has a​ grid to​ help keep you aligned as​ you began you design .​
In CAD, there is​ a​ grid you snap to, or​ guides to​ keep you straight .​
We had hard plastic templates to​ draw curves .​
CAD has numerous tools to​ draw curves and lines .​
We had calculators to​ figure out distances and ratios .​
CAD does this automatically.
Overall, you can view CAD as​ replacing Drafting .​
CAD moved the same type of​ process into a​ more flexible and efficient environment .​
CAD has also helped out with networking of​ designs .​
Different designers and engineers can work on the same assembly in​ different parts at​ the same time .​
This team effort really moves the overall process along much faster.
However, as​ far as​ print reading goes, that is​ about the same as​ it​ was before .​
Drafting outputs prints and CAD outputs prints .​
a​ human still needs to​ be able to​ read them and make sense of​ them .​
a​ plus with CAD is​ that it​ is​ much more standardized and clear .​
Many times before, prints were unique to​ their maker .​
Similar to​ handwriting, you could not always figure out what the engineer wanted to​ convey to​ you .​
CAD cleans all that up.
CAD is​ the way we work today .​
I​ would be very surprised if​ you could come across a​ shop that has hand drawn prints .​
It just isn't practical .​
Precision and accurate prints are the way manufacturing increases efficiency.
