Surface Polishing

[doganer20]

I am making a toy plane and I made some bad extrudes instead of deleting my mistakes. The inside of the plane looks like this and is there any way to smooth the surface? I cannot edit or delete the timeline because an error always occurs. I used loft to create the main body fyi.

I was watching a video today where the instructor was just selecting faces he didn't want and deleted them and the whole thing magically "healed" itself. I wonder if this might be possible in your case? Mind you, in the tutorial I was watching, it was specifically with an imported model that he was doing this, so I don't know if that's one of the requirements to get it to work. Here's the video and the stuff I'm referring to is almost right at the end. https://www.autodesk.com/autodesk-university/class/100-Things-Beginners-Should-Learn-Fusion-360-2020

Please attach an f3d file of your model.

it is possible that "delete with heal" can help here.  But, in your interest, it would be best to go back in the timeline and understand where these artifacts came from in the first place.  Likely, those reflect bad modeling practices along the way.

I agree with @jeff_strater  Fix the root cause, not the symptoms,

If you can share your design we can help you through the process and you'll learn how to avoid these things in the future.

Firstly thanks for all replies, here is f3d file

No file was attached!

Oh interesting it should be fine now

The rear many, many unnamed sketches in the top level sketch folder. Most  of them likely would be better located in the appropriate component. I'll refer you to Fusion 360 R.U.L.E # 1 & 2.

Almost all of your sketches are not fully constrained and dimensioned. That is just asking for  trouble! It is very easy to destroy a design just by accidentally dragging around on a sketch object even when not actively editing a sketch.

There is no need to use that man loft profiles for that simple geometry.

I'll keep looking through this...

You need to have a clear picture in your mind on how to construct this plane. All of those little extrudes of adding something then cutting it away later is bad practice. If you start over, you could probably accomplish the task in 1/10th as many operations. Also following rules 1 and 2 like @TrippyLighting mentions is a good idea.

Thank you very much. It was my first project and so much has been learned. Sadly deadline is coming so I cannot start over again. Rules 1 and 2 are life-saver. Notes taken!
