The drawing of custom components

Draw your own Package in the PCB view, draw your own symbol in the Schematic view. Three general steps are needed:

FIRST: Start drawing the package!

Go to PCB view with [F3] and select an adequate grid, metric or imperial (recommended: 0,635 mm = 25,00 mil = 1/40 inch). Draw a package (= land pattern of the soldering pads including outline of the device) using the required functions from the Drawing tool . After having finished the drawing select all (Capture Window). Hover the cursor to the desired handle cross position and press keyboard key [x] for eXporting and saving it to the database VIDEO on package drawing

SECOND: Draw the symbol!

Draw a symbol (= showing the electrical function in the schematic) in the schematic view according to its data sheet. Leave the grid 0.635 mm = 25 mil = 1/40 inch. Use the required functions from the Drawing tool . After having finished select all, hover the cursor to the desired handle cross position and merge it by the use of keybord key [y] to a sYmbol. Remark: A component as a whole can be made of several symbols e.g. gates. That's why we need the [y] procedure first. Now select the symbol(s) by a Capture Window and eXport it by pressing keyboard key [x] to the database. VIDEO on symbol drawing

THIRD: Assign the package to the symbol and save!

When exporting the symbol to the data base assign a matching package to it. For example the one you had drawn in the first step. This is not a must. You can assign any package to it but it is a common way.

new project with schematic. You find yourself on an empty schematic page in pointer mode.
look at sidebar to the right in section "Settings": Release this button:
open the Component database by [F2] (in earlier versions the Library Browser opens)
click M2 on the image (symbol, package or 3D image) you like to change. A context menu opens.
use the option you desire to do changes.
only symbol elements:
- My symbol consists of several symbol-entities like several gates: Highlight one of them completely, hover the cursor to the position where its handle shall appear and press [y]. Then highlight the next gate and do the same and so on. At the end highlight them all for merging them to one symbol, press [x] and export the symbol to the data base.
- My symbol consists of only one symbol-entity like a capacitor or a resistor: Highlight it completely and hover the mouse to the place where the handle shall appear. Now press [x] in order to export it (no [y] neccessary).

For packages:

after all adjustments have been made, place the cursor at desired handle position
save to the data base by [x] and follow the dialog of the data base dialog.

The package and symbol assistant is meant for packages and symbols having a higher number of pins/pads.

open the Symbol assistant in Menu Components or the Package assistant in Menu Packages
edit any element by the use of a script and save it again
