The Import/Export page controls how FeatureCAM imports or exports files. It contains the following options:
Always replace object on import — Select this option to overwrite objects of the same name when you import. Deselected prompts for every replacement. You can’t have two objects with the same name.
Smooth EZ-MILL curves — Select this option to improve EZ-MILL curves on import because FeatureCAM has a higher resolution curve format.
Keep IGES import log file — Select this option to keep a log of the import process for later review or troubleshooting.
IGES log file name — Enter the path and filename for saving a record of the import process.
Import IGES entity of type:
Logically dependent — can exist by itself but is also referenced by another entity (case of groups or grouping situation).
Physically dependent — generally, you should deselect this option to indicate you do not want physically dependent entities to be imported. But if you are having trouble with your IGES file and it is not importing properly, try selecting this option and re-importing. Entities in an IGES file are marked to be either physically dependent or not. Those that are marked to be physically dependent are entities that are used in the construction of other entities. For example, a trimming loop is physically dependent upon the trimmed surface that uses it. The trimming loop is not important all by itself, but is instead a building block of something else. The trimmed surface is in turn marked physically dependent to indicate that it is a building block of a parent entity, a solid. By selecting Physically dependent, you cause FeatureCAM to show everything in the IGES file - not just the top-level entities that are usually shown, but also all of the lower-level building blocks. This is generally not what you want. Generally you want only the top-level entity, for example the solid.
Both physically and logically dependent — meets both logically and physically dependent criteria (is referenced by at least two other entities — the parent for the logical link cannot be the parent for the physical as well).
Center stock automatically — Select this option to automatically size and position the stock so that it covers the imported data.
Number of decimal places in IGES export — determines how finely data is exported to the IGES format.
