HI Everyone... Is it possible to extract or copy a surface from a STEP file in Inventor 2013 ?
If your STEP contains a number of surfaces and you want to keep only one surface. On the 'Open' dialog box click the 'Options' button near the bottom.
In the 'STEP Import Options' dialog make sure that 'Create Surfaces As' pull down is set to 'Multiple Composite Features' so that Inventor will not merge all surfaces into a single composite feature.
Once the import is successful then you will have a collection of surface features where you can then remove any that you do not wish to keep
