| A layout or a subcell of it can be saved to either GDS2 or OASIS. |
| To save a layout, choose "Save As" from the "File" menu. To save just a cell, select the cell in |
| the cell tree (it does not need to be the currently shown one) and select "Save Current Cell As" from |
| the context menu (right mouse button) of the cell tree. |
| </p><p> |
| A file dialog will pop up to select the file name to which to write the cell or layout. |
| After a file has been selected, an option dialog will be shown to specify further options. |
| In this dialog, it is possible to constrain saving to a subset of layers, i.e. just visible ones. |
| Also, the database unit can be changed or the layout can be scaled by a given factor. |
| </p><p> |
| For OASIS, a compression level can be specified. At a level of 0, no particular attempt is made to |
| compress shapes. At higher levels, shapes are classified and array compression is tried. The higher |
| the level, the more attempts are made to compress shapes into arrays. In particular for flat layouts, |
| compression of shapes requires some memory and slows down OASIS writing considerably. |
