Loft not created correctly

Hi! I'm the OC from this post, thank you all for your help with the last problem, now I encountered another problem when making a new body with different dimensions, I tried to replicate the same steps @TrippyLighting did, but the loft at the nose section doesn't look alright. Thank you!

Examine the Attached file.

Thank you, but I expected it to look something like the first body I made, I used surface loft there.

@nectarietotan

I don't see this geometry in the file that you attached.

This is from a previous file I made using @TrippyLighting instructions from my previous post, and everything went ok, but now with other geometries and dimensions it doesn't work the same.

@nectarietotan

It is not clear to me what you expect to see at this point?

I expected a shape similar to the one I mentioned, with a round contour flat surface at the top, like a 7mm radius all over the contour, I don't know how to explain...

@nectarietotan

But you have a sharp corner?

If you want it rounded - then you will have to trim the surface.

...and, you will also have to trim this surface (or create without the point to begin with).

on the first model I didn't have to do it, when selecting Keep Tangent Edges, the line would connect itself correctly to the edge of the body, as shown in the photo, where I will draw a black line to show how I expected the contour to be.

@nectarietotan

What is the name of this "first model" that you reference?

Are you referring to the model in picture of another model?

Did you Attach that file here for reference?

These are different geometries.

I saw one attachment, not the other for comparison.

Clearly there is a sharp point in one that is not in the other.

I went to the other discussion thread linked in your problem description and did not see this geometry in that thread.

But I did see a bunch of unconstrained sketches (did you turn off history in that file at some point).

Yes, I usually work with the history off, so I can't be bothered when returning to a sketch or something.., here's the file, I think I did the same lofts but it ended nicer as in the photo....., the body named "0" is the untampered version of the body.

@nectarietotan

Good luck with that - I can't be bothered by wasting my time without a history.

I am surprised that you do not see the obvious difference in the geometry, but without the history I can't explain much about it.
