Difficulty Adding Holes to the Inside of a Curved Surface

[cody_williams1290]

Hi Everyone,

I'm having difficulty adding holes to the inside of this curved surface. No error messages show up, I just get a black fill where the hole should be. I have no issues adding them to the outside.

I want to add a couple of holes with a counterbore to house some 5mm LEDs so that the LEDs themselves are pointing outward.

• Material thickness: 5.0 mm
• Hole depth: through
• Hole diameter: 5.01 mm
• Counterbore depth: 4.80 mm
• Counterbore diameter: 6.01 mm

How could I add holes to the inside? 

Any help would be greatly appreciated.

That's really odd to get a black hole.  The technique in this screencast also works for compound curved surfaces.  For compound curved surfaces, you need to create a plane tangent to the point where you want the hole, then create a plane using offset plane inside the component.  You can also use Plane at angle to create the inner plane.  Once you have the inner plane, create a sketch and place a point (or a circle) at the axis point of the counterbore hole.

Another way to create the point at the counterbore location is to use Project to surface and select the inner face of the component.  You may still need to create a tangent plane or a plane at angle as the Hole command doesn't have any way to change the axis angle (other than 90 degrees).
