Revolve Question 2

[cygnas]

I made a simple 2d contour sketch (front plane) and tried to revolve around the centerline contained in the same sketch. Usually as soon as I choose revolve, it automatically picks the contour and gives me a preview. This time it did not. I actually had to place my arrow over the "inside" of the sketch and it highlighted and I was able to make the revolve. For some reason SW also changed my sketch to a 3D sketch from 2D.

Why does this happen?

Thanks

Did you create half the contour of the part or the whole contour around the CL?

The part has a hole through the center, therefor I created the top half of the part (closed contour) offset from the C/L half the diameter of the thru hole.

I'm in the habbit of picking my axis for the revolve before I go thorugh the action. I have no clue why it converted it to a 3D sketch.

I just created a revolve as you said you did and no problem. Can you send a pic of what yours looks like?

Yes I can, is there a way to include a screen shot with my reply? I tried "print screen" paste into MS Paint, copy and paste into my reply but will not attach.

You have to place the image into a website & use the following code to retrieve into a post:-

If you have more than one construction line in your sketch, you either need to have the revolve line selected when you select the revolve command, or need to select it later. (SWX needs you to tell it WHICH line to revolve about.)

As for the 3D sketch part...no idea. Are you sure you began as a 2D sketch?

 

[cygnas]

Here is an attempt at including a picture of the sketch.

I don't see a Centreline! Did you include one in the sketch?

1) As Arlin pointed out, only one centreline can be selected.
2) You cannot have multiple lines.
3) The sketch must be closed ... no gaps, overlaps or crossed lines.

Get the sketch in Edit mode, go to Tools > Sketch Tools > Check sketch for feature ... to see if a problem exists. Only one problem per analysis is shown, so multiple checks may be in order. More details on this can be found in the Help files under Sketch tools, diagnostics

& all the best.

I would like to see the entire screen shot because seeing that might help determine the problem.

From what I see, the sketch looks correct. As others said, check to make sure there are no extra lines/gaps/overlaying lines. Only one CL selected.

Here is the screen shot with FMT. I did try the following:

I would remove the revolve feature, because you selected the contour in the bottom of the tree while making the feature. You don't need to do this. You should only have to pick the centerline.

If you did the check sketch for feature, did it show you and error or give an error? or is that what you mean at the end of your statement? "No errors found"

"No Errors Found" is what the response was when I did the check sketch for feature.

 

[SBaugh]

Then what is your step by step method of what your doing to revolve this sketch?

1. Front Plane, insert new sketch.
2. Create C/L originating from the Origin.
3. Complete closed profile.
4. Dimension sketch profile 1/2 the Ø from the C/L.
5. Make C/L active and choose Insert, Boss/Base, Revolve.
6. At this point it would not automatically choose the closed profile until I placed my cursor over the closed profile. When I did this the closed profile became a different color and allowed the selection.

 

[cygnas]

I can email the file to anyone who would like to tear it apart to try and determine how it changed from a 2d sketch to a 3d sketch automatically.

 

[SBaugh]

Email it to me. The reason it changes color is because it asking for a contour selection and that's the icon under your feature after you OK'ed it.
