Recess part of component

[marsheng]

Sketch 1 is the outline
Sketch 2 is thinning the bottom part by -2 mm - Tried various options but can't get this to work.
Sketch 3 is a test and it works fine.

Stumped !!!

Once this is right, Is there a quick way to duplicate sketch 2 on the other side ?

The part is 10 mm thick with the bottom 6 mm, with 2mm removed off each side.

Thanks Wallace

Extrusion 2 is sitting on the XY plane and because it is a cut, it goes backwards.
Extrusion 3 is sitting on the front face and cutting backwards into the object.

Right click on Extrusion 2 and choose Edit, then move the model around so you can see the cut preview and you will understand.

Use 'project to sketch' and project the previous sketch.

If your original extrusion had been 'mid-plane', using feature mirror across XY plane from your recess cut might have been an option.

For your recess cut - just un-check the 'reverse' option.

Thanks - Rookie mistake.

I completed the part and then started renaming the operations. When I changed Sketch 6 to hole, I got an error. I deleted the hole and then recreated it. I get the same message.

Update.

I opened my saved file (Ver3 before renaming) and all looked good. Then I went back to Ver 4, the faulty one (was still open and file as attached) and now I can do the hole without an issue.!
Confused.
