10 Wires, Circles, Arcs, Rectangles, and Text<br />

Wires, circles, arcs, rectangles, and text are created with the WIRE,<br />

CIRCLE, ARC, RECTANGLE and TEXT commands. On one hand these<br />

objects serve as pure drawing elements for symbols, packages, frames etc.,<br />

and on the other hand they can perform special functions, such as the definition<br />

of restricted areas.<br />

First a new schematic file is to be created. Close all of the editor windows<br />

and select<br />

⇒ File/New/Schematic<br />

from the Control Panel.<br />

A new file with the name untitled.sch is now created. Normally you should<br />

diagonal and orthogonal modes you will find some to draw 90°-arcs and<br />

free definable arcs.<br />

However, in the Schematic Editor the arc modes can be selected only in<br />

the parameter toolbar, not with the right mouse button.<br />

Keeping the Shift key pressed while clicking the right mouse button will<br />

change the selection order. Pressing the Ctrl key toggles between corresponding<br />

wire bends.<br />

When the connection is displayed in a square angle, press the left hand button<br />
