Yes, sure that is possible. The minimum possible size is one databaseunit. The databaseunits are stored with a GDS and be be set between 1e-99m and 1e99m. By default for new GDS it is set to 1µm. In your case I would recommend a setting of 5E-10m. ![Screenshot_20220723_090243.png](/api/img.php?thread=20220723-1302&file=Screenshot20220723090243.png) But always remember when changing the databaseunits, it will change the maximal design size as well. GDS is 32 bit and with a databaseunits of 1nm the maximal design space is about +-2m, with 0.5nm +-1m and so on.
