Creating a sloped groove

[rickduley]

As you will see from the drawing, the groove is 22mm deep viewed parallel to the slope.  The exercise required the groove to be 22mm deep on the vertical (not 22.78 as shown).

How can I do that?

The groove is indeed 22mm deep exactly like the extrusion depth. The measurement of 22.776mm is on the face not perpendicular to the extrusion profile plane. Either you need to make the face perpendicular to the exutrusion profile plane or you need to change your extrusion profile plane. You cannot have both.

Thanks!

See attached example.

Be sure to reproduce it on you own so that you can figure out exactly how it was done.

Remember the discussion on the BORN Technique?

If you are creating workplanes on beginner objects like this - you are almost certainly doing too much work.

On a robust part - all, or nearly all, of the features can be deleted without the sketches going sick.

Hi

There are a few ways of doing it, using your existing method, I would create some workplanes and the use the "Extrude - TO" option.

My preferred solution would be to create a sketch on the part midplane and cut the desired profile symetrically by 13mm

Reg,

I don't believe your 22 dim is correct.

I was just analysing the OP's question of:

"The exercise required the groove to be 22mm deep on the vertical (not 22.78 as shown)."

Using my method, I have answered the question.

I did forget to show the parallel constraint in my view though.

The original ACAD drawing was absolutely correct?

Well, actually it is 22.776075969 mm

I don't understand your image related to the problem?

[rhasell]

Fair enough.

I did not open the file in AutoCAD, The file automatically opened in inventor (From the download link), and was surprised to find that it was an Inventor drawing and not an AutoCAD drawing.

I have made the assumption that the OP created the drawing and discovered that the dimensions did not match to the original exercise.

[JDMather]

I didn't realize that the dwg was an Inventor dwg, but in any case - I am sure the dimensions are correct for a beginner problem like this.  Out on the machine shop floor the only dimension that could be reliably be held is 22 as the parallel slot depth.

Thanks to you both. I didn't think of working from the XY Plane.
