Example and Tips
• Copy selected components from the
palette on the first slide.
• Nudge into place and add connectors as
needed. All components should have
end-points that lie on the default grid
For intersection nodes, doubleclick on the line, select “Colors
and Lines” tab, and change
“End-Style”. (Note, this also
works for resistors)

For simple labels use
“Symbol…” for special
characters like μ and Ω
For more complex labels,
use equation editor, e.g.:
