Hi there, I use Rhino a lot for manipulating surfaces. Often, it involves moving control points in the Z axis. However, depending on the resolution of the surface or mesh, the jaggedness needs custom smoothing to make a natural surface. Is it possible to manipulate control points so that there’s …

there is _softTransform [image] https://docs.mcneel.com/rhino/7/help/en-us/index.htm#commands/softtransform.htm?Highlight=softtransform there is also _softMove for point-wise movements - not sure if this helps https://docs.mcneel.com/rhino/7/help/en-us/index.htm#commands/softmove.htm …

Hi Tom, thanks for your reply I think SoftMove is the applicable command, but it’s not efficient for what I’m doing. I have used lasso or brush to select defined set of control points, and I want a customisable falloff range for that selection. Options for falloff could include: Falloff profile:…

[image] Jdelavaulx: I want a customisable falloff range sounds like a custom brush in z-brush to me or mesh sculpting in blender one workflow that might be interesting in rhino: set up a material with a displacement map. set up mapping etc until the displacement is doing the desired trans…

It does sound like a z-brush like in blender. Perhaps something similar could be implemented in rhino? Or a rudimentary version perhaps -Jeremy

‘Customplay Golf’ (2005) I used many years ago to design golf courses had the type of feature I’m really looking for in Rhino. It’s dealing with a mesh, but has custom falloff types and distance. You can see it in this short video I just made. -Jeremy

[image] This screenshot explains the idea pretty clearly :slight_smile: Would something similar be difficult to integrate into the transform capabilities of Rhino? -Jeremy

did you play with _softTransform enable it shape = smooth set the radius… combine it with gumball or even _setPt the interface is less accessible and the smooth shape is not as balanced as your example. your wish would be: a more visual Interface for softtransform a custom fall off shape w…

Hi Tom, thanks for the help :slight_smile: I just played around with soft transform, but yes, I feel that it could be more visual/intuitive. Setting the radius of the effect in model units is less intuitive than seeing the effect like in the example I provided. After a preliminary test, there are…

I would use SelBrushPoints, SoftTransform, and Gumball.

Hi Tom, I apologise if my answer was a bit much. Regardless of the other control point transform ideas, perhaps the current softtransform might be better if it had two changes. Some visualisation of the falloff so that when you change falloff distance, you can see what it affects. Also, the gumbal…

Hi, can you take a look at the new SoftTransform work in the WIP and let us know if this helps?
