You can create 5-axis Hole features from simple circles in space. You do not need to use solids, Feature Recognition, or surfaces.
The following 5-axis part example was created with only geometry and curves:
To create a 5-axis Hole feature on the drafted corner side area, you just need a circle in the correct position, in this example parallel with the drafted face.
This circle lies at a different vector orientation to the Z-axis Setup. You can create a Hole feature that is normal to the selected circle.
To create a Hole feature from a circle:
The New Feature wizard is displayed, with Hole in the From Dimensions section selected:
The New Feature - Dimensions page is displayed. FeatureCAM uses the Diameter from the circle by default.
The direction of the Hole is based on how the geometry was created, and may be created in the wrong direction, for example:
