How can a blind hole be created in a solid?

Answer

In RFEM, it is possible to create a blind hole in a solid via a solid intersection.


For the conversion, two valid solids have to be available. One solid represents the component to be drilled and the other solid represents a simplified drill. The simplified drill solid should consist of a cylindrical shank with an applied conical tip. The diameter of the shank is to be modeled with the blind hole diameter and the length of the shank longer than the blind hole depth.

For intersection, place the drilling solid in relation to the solid to be drilled on the position of the planned blind hole. It is important that the drilling solid protrudes slightly above the basic volume. Then mark both solids and select the solid option "New Compound Solid" in the shortcut menu. By specifying which solid B (drilling solid) should be subtracted from which volume A (solid to be drilled) and activating the option "Solid B as Cavity", the program deactivates the two initial solids and creates a new combined solid. This solid represents the blind hole and depends intelligently on the geometric specifications of the two initial solids.
