2. Confirmation of Component Shape
This confirmation should be made to look for similar-shaped compo-
nents in the standard component library.
Confirm to which component shape the selected component has.
When a component shape is specified at the time of new creation, data
can be created easily.
2.1 Check Procedure
(1) Confirm whether or not leads are attached to the components.
2. Confirmation of Component Shape

Components
All edges of a component
should be formed by straight
lines without any convex
and concave parts.
Or, three corners can be
recognized.
At least 2 edges can be
recognized.
Is the
outside of the
component enclosed
by four straight lines which
are crossed at an angle
of 90 with each
other?
