Removal of portion of object froma curved surface.

Anonymous — Fri, 06 Sep 2019 10:38:12 GMT

Good day hive mind,

I am trying to find some help on a small matter that I just can not seem to find a work around for. I have a curved surface into which is embedded a cylinder. what I am trying to do is remove the inner portion of the cylinder so the surface is once again smooth and curved.

So far, I have tried the following:

1. Push/Pull the outer circumference of the inner cylinder but it effects the whole cylinder (inner & outer).

2. Push/Pull the inner surface of the curved piece but it only buries the inner portion of the cylinder (and makes the curve to deep).

3. trying to create a sketch that follows the inside surface of the curve using a line from the existing sketch used to create the curve and then using the extrude to 'cut' the offending portion but I cant seem to select that original sketch line?

I am far from an expert with Fusion 360 (only to day I learnt how to copy a sketch thanks to this forum), but I am not sure which direction I should be heading in? Picture attached for reference but any advice is most gratefully appreciated.

Giles

Could you share your file so we don't have to make the effort of recreating everything you have?

As well as wath seth said. Please don't attach pictures. There's an option Photos on the editor toolbar to embed them, please use this option.

Thanks.

I am going to show you two methods.

First, use a new feature operation to cut off the inside of the cylinder. I show modifying the sketch of the curve, and using Extrude to cut of everything on the inside of it. But you could instead make a new sketch for this purpose, or Extrude the cylinder again, only up to the curved face.

Second, and I think a better idea, is to just model it correctly in the first place. Only extrude the cylinder FROM where you want and TO where you want. I show editing the original extrude feature and correcting the settings. I believe this is a better idea because you don't end up with extra steps/clutter in the timeline.
