The Designer General’s WARNING:
The tools we use today for designing and drawing,
principally AutoCAD and other software programs,
make the process faster, more efficient and make
coordination between drawings easier.
There is an unfortunate side effect of AutoCAD
which is the hard-line style makes all drawings
look more finished, more thought out than they
may actually be.
This often leads people to incorrectly conclude that
concepts and ideas shown at the early stages of a
design process are finished designs.
Let us assure you: this is not the case.
