[Request] Quick & Dirty lay flat

Scripting
1

If someone is interested, can you make this one (in Python):

  • Call the script via macro or keystroke
  • if object wasn’t pre-selected, an option to select the object
  • click on a planar face of the object
  • that face lays flat on world plane

that’s it

whatever orientation that face happens to be in space is how it plops to Z=0
(as in, there’s no describing the plane using something like Orient3pt)

for example, say you select a surface with Auto CPlane turned on. Whatever that chooses for X,Y,Z can just keep X,Y point the same and just remaps to the regular cplane with Z being at zero.

just looking for a one-click deal to get an object laying flat with desired surface facing downwards.

thanks

Do you want to just move the bottom face or do you want to reorient the entire object such that the bottom face is z= 0

Hello,
It can be run in ScriptEditor in Rhino8.
I made it so easy that it might work weird…

Hi @11159 – How would I possibly make this work for meshes?

Thanks for posting!

Hi, @Alan_Farkas

I have not touched Mesh much, so I don’t know how to find the proper normals for a pentagonal or larger mesh,

so I tried to run it for triangular and quadrilateral mesh faces.

If I need more than pentagons, I will try to figure out how to do it.
