I’ve tried… with scale 2D, 1D and it doesn’t work as I thought.
The point is that scaling/shrinking should be from 0 at the start line to -1mm at the tip of shape.
As I did a hell of manual corrections to get final shape, I would like to avoid the same work from the begining (first shape was SurfaceFromNetwork and later manual corrections).
So I’m looking forward to any ideas to try.
Finally it should be shrinked similar to red line below from all directions.
This is good riddle! The obvious, but time-consuming solution is to shrink every slice of the control points separately by different ratio. Pascal is not shrinking the cross-sections - he only makes the nose shorter, so he shrinks the distance between the cross-sections.
I tried scale it similar to presented footage - the point is I want to preserve lenght and change diameters smoothly from 0 to -1 (more or less).
Tapper is a good hint, I hope it might be the way - I can’t only keep the shape with it.
It tends to flatten curved edges. Please have a look below.
I tried to play with parameters - honestly don’t underestand all of them fully, so maybe there is one which could help to maintain shape?
Finally I struggled with CageEdit. Results are promissing and again not all parametr are clear to me. One of them is falloff distance. By blind trials I see a difference but … I don’t get it.
What is falloff distance? And I’m sorry from below manual it is too hard to underestand to me
Apparently you want to accelerate the shrinkage at the tip of the nose (on the right side of your sketch). Taper cannot do that, but CageEdit can. If you want to try it out, make box-shaped cage that has rows of three control points in the axial direction. (Make box first using Box command, then adjust number of control points with Rebuild command or RebuildUV command.) Shrink the control points of the cage in two cross sections: at the tip of the nose and in the middle. (You can shrink the control points with the Gumball/Shift, or with Scale2D command, or with Scale command.)
my 2 eurocents:
Cut along the line “start of shrinking”, then use blendsurface or sweep to construct the surface exactly as you need.
It’s just too much of a hassle to try to manipulate the control points.
