Mesh/Form modeling Help

Anonymous — Fri, 11 Dec 2020 00:04:23 GMT

Hello again, I recently asked for help in getting rid of a spline error which was resolved in that my arc from of the spline was too concave. I understand that is the reason for the error but not why? Or as to what to what a work around for this dilemma would be. I'm trying to use an organic form body with a sharp face that transitions to a smooth curve. not a dead stop like a crease but something gradual. Is this Possible? My uploaded file I hope illustrates what I'm trying to accomplish. My best effort has smoothed most of the transition except for the flat face portion. The last sketch represents the continuation of the curve I'm looking for up to the flat face. I hope this makes sense and any and all help is much appreciated.

You mean like this ?

See attached model and inspect hjow the edge loops flow. I removed that horrible creasing. Lern to model without it.

@TrippyLighting Thanks for your model as a reference to Mesh Modeling my desired contour. Also I appreciate your constructive criticism about creases. lol. Could you elaborate on why you don't like creases and maybe a screencast of your workflow?

I don't have time for a screencast right this moment. The problem with creasing is that I have seen a good number of models here on the forum where the user applied a crease and then continued to model with the crease applied.

After a while, the internal tangent handles of the. Model go so "out of whack" that the only way to
"fix" the T-Spline was to export ant the control cage as a .obj and then reimport and convert yo a T-Spline.

In other words, there is a bug somewhere and no workaround other than what I just posted.
