Cut-out on a curved surface 2

[tinamstevens2004]

Help from the experts, please???? I am new to NX, only about 6 months of experience. I am currently using NX7.5 migrating from years of use with Inventor.I am trying to create a sketch on a curved surface that when I extrude it will have a uniform depth of .04 in. I have tried projecting the sketch to the surface which works but when I try to subtract it I get various issues that result in failure no matter how I try to do it. Though I don't need step by step instructions bear in mind I am still learning NX. Suggestions would be greatly appreciated!

To get the curve onto the curved surface:
- create sketching plane (datum) tangential to the surface
- sketch the curve on this plane
- Insert-->Curve from Curves-->Wrap/Unwrap Curve (select the curve, the surface, then the plane

That gets you the sketch curve on the surface. Now it depends if the profile of the slot is regular or changes for how you proceed next.

Hi,
Here is a video you may find useful (sorry the video quality may not be that good as i recorded it in a jiffy).It is a mp4 file.It is only one option of achieving the result.

Thanks deedub777. The problem is not the sketch. The problem comes after I wrap the sketch on the surface and try to subtract the resulting cutout. It must be a uniform depth of .04in. No matter how I have tried to subtract the cutout I get errors or the wrong results. Suggestions on how you would proceed after the sketch & wrap??

Hi tinamstevens2004,
You can use divide face and then use Synchronous Tech (offset region) as shown in my video attached earlier.

yes, as kapmnit123 says, divide the face then offset is the simplest way

Thanks kapmnit123! The video was awesome! It worked great and I now have a completed model with the cam cut to the perfect depth all the way around! You guys are great. Thanks to both of you for your advice! Here is the finished (or nearly finished) part. Thanks again!!!
