Reply To: How to open and modify a gds?

Hello yw3a14,

This tutorial will be helpful.
Basically, create a new cell, load the gds with load_gds().put() and create and put pins with nd.Pin().put(). You can also flatten the gds in your new cell using instantiate=False:

import nazca as nd

with nd.Cell(name='cellname') as C:
    nd.load_gds(
        filename='<filename>',
        cellname='<cellname>',
        instantiate=False, 
    ).put(0) # puts (0, 0) in the gds at (0, 0) of cell C.

    # Add Pins
    nd.Pin('<name>', width=<width>, xs=...).put(<x>, <y>, <angle>) 
    ...

C.put(0)
