You can modify the package outline in an complexe editor or in the simple package editor with some basic handlings:

Here is an top area with width and height for the package outline, you have an helpfull search button and can rount/cuts the corner for the package definition.

Below you find an list with all pin definitions, each has an Geometry type like rectangle, circle or polygon with the size and the pin position X/Y.

On the right side there is an preview with simple transform options (move pin or body).

And some buttons e.g. for rotate, add/remove pins and "Make IPC Conform" to switch the definition in an library standard orientation.

Edit multy selection, renumber the pins and change outline and pitch values.

In the graphics area you can measure, zoom switch mouse tools and change view:
