I want to implement a functionality where user will select several hole features and I want to cut all the material from part considering outer boundary of selected features. Can this be done? Which API I am supposed to use?

For e.g. User selects 4 holes which are as follows

Then the cutout should look like -

So red part shows material which will be removed from part. So this looks like a custom cut based on the sketch. Can I create this sketch based on input features? Can anyone guide me?

Thanks
