How to resize a symbol
in the drawing
A symbol can be resized by dragging its handles with your mouse. Handles in the corners resize the symbol while maintaining the width / height ratio. The other handles resize the symbol only in the appropriate direction.
The size of a symbol can also be changed in the Properties panel, by entering values of the "scale" property for X and Y axis.
It is possible to set the initial scale of the newly inserted symbols to the drawing. This option can be entered in the program settings (F12) - Symbols - field "initial scale of the symbols".
If you increase the size of a symbol and you will feel that their lines are too thin, you can set a ratio by which the thickness of the lines and wires is multiplied.
For example, if you specify the ratio 1.5, the line thickness will change from 0.2 mm to 0.3 mm (1.5 x 0.2 = 0.3). This setting can be entered in the program settings (F12) - Paths - field "Symbols and wires line thickness ratio.
in the editor
In the symbols editor, it is possible to change the size of a symbol using the menu command Object - Resize a Symbol. A dialog box appears where you can set a new size using the slider.
This feature is intended for the case when you have created a symbol and later realized that it should have a different size.
