Extrude a 3D sketch

[ysnyder]

Hey, 

 I am trying to extrude this 3D sketch into the solid to cut out 0.2mm of material. I am new to using 3D sketches in Inventor. Can someone please show me what I am doing wrong? Thank you for your time.

I am not at my Inventor 2022 machine at the moment, but can you use the sketch to Split the face and then Thicken/Offset (Cut or Add) the split face?

It looks like there are some anomalies Left to Right (not symmetrical about XZ plane).

Can't open this part anyway. 'version9' is missing.

I'm assuming this is a derived part?

You need to either break or suppress the link, or include version9 as well. 

[SharkDesign]

I returned to my computer and it had loaded, but is unresolved. 

You have gaps in your sketch, so that's not a good start. Where has the 3D sketch come from? Is that projected from the part that is missing?

[SharkDesign]

This is not connected either.

Once your sketch is fixed so it's a complete loop, you can use ruled surface to extrude the loop. 

Depending on what you want to do next, you can split the part. cut the part, thicken the surface and cut that, turn the surface into a solid and cut the lot out. It's up to you. 

I used the UCS Y Axis as the vector.

P.S. in ruled surface you need the third option down on the left as shown in the image above.

[SharkDesign]

OK, to get the 2mm cut you want. 

I had to use two ruled surfaces, one in each direction because your 3D sketch is not quite in the right place.

Use the ruled surface to split the face (once with each ruled surface).

If you turn off the visibility of the surfaces, you should now have this:

Then try thicken/offset

Is this the shape you want?

You'll need to clean up your geometry first for this to work properly.

Alternatively, if this is a socket and another part is fitting into it, a much easier way is to use this method:

Depending on where that sketch is coming from, you could just put it on an offset plane as 2d and extrude it into the part as a surface, split and thicken. Then you don't even need a 3d sketch.

Why is this sketch not centered?

Why is the sketch plane not parallel to the XY Plane?

[ysnyder]

This 3D sketch originated from this part. 

[ysnyder]

That was not intentional. I am not sure how that happened this part was derived and it should have been on center. Is there a way to move the part to the center position?

The file is here.

What diameter is the circle in Sketch3 in this file?

[ysnyder]

Thank you for your input, it was very helpful. How did you get the thicken command to work? My geometry is fixed and I used the ruled surface command. I also split the surface, but my thicken command keeps failing... Any advice?  

[SharkDesign]

Is it pointing in the right direction and is it set to cut as shown in my
image?

[ysnyder]

Sorry for the delayed response. Yes, I did what you showed. By any chance do you have the part file that you used in your example? That way I can check if there is anything I missed. 

[SharkDesign]

Maybe, I can't check until tomorrow night though 

[ysnyder]

Thank you for all your help so far. 

[SharkDesign]

Here it is. Bare in mind that I did this to demonstrate how to do it. I butchered your sketches to get them working so it won't be the exact shape you were after.
