I’m looking for a construction plane option that is circular, IE, when you move it moves the object along a circular plane or in an arch. Maybe Y axis can be fixed & X can deviate or vice versa, I am currently working on a circular floor plan so i need to move across the arch and pin to the center bisector line.
I have asked for a circular grid in the past but nothing came of it. Rhino doesn’t have a circular grid, though Rhino can accept polar coordinates.
As a work around you could make a bunch of concentric circles with emanating line work.
Then use intersect snap and end snap to snap to the grid. Or array circular points and use snap to point.
Grasshopper, I think using paneling tools has a polar grid but you might have to fool with it for it to output something useful for yourself. Attached is a quick image I made, I double clicked on the Gh canvas and typed in grid then chose polar.

I’ll use the Grid as the tile, I guess that’s a plus.
That’s a nice looking grid!
Maybe you know just thought I’d throw it out there;
Since all your objects are circular and align to the circular shape of your grid you can easily rotate them or copy and rotate using your grid center point.
If the center of your grid is not at cplane center 0,0,0 or world center w0,0,0
You can use evaluate point to get the grid center point information.
- Open the macro editor
- Add the rotate command maybe with a pause pause enter to allow for selecting objects
- Copy paste the point info from evaluate point into the macro editor or use 0,0,0 or W0,0,0 if that point is one of them.*
This will allow you to rotate/copy those objects easily by running the macro when you need it and Rhino will remember that macro when you reopen rhino if you don’t change it.
Also you can use near snap to slide your objects along your grid if they fall outside of the grid emanating lines intersections or locations.

Hey @3dsynergy; I’ve never setup a macro, but it’s been a challenge working on the polar grid. I thought Rhino, being such a powerful mathematics program, it should have a world that is a polar grid. Your first idea was promising, but I am novice at Grasshopper. Thank you.
Myself and others have wished for this for a number of Rhino versions and even wanted grids that work on arbitrary solid shapes. McNeel hasn’t done anything with grids since V2, see my thread somewhere from the past about Grid Rhino’s underdeveloped son, or something like that.
I would open Grasshopper and try the component shown. It’s pretty straight forward. Also go through a few basic tuts or watch them on Youtube. Then create a new thread in the Grasshopper category referencing this thread with what you are trying to do and your definition file and geo.
You won’t be sorry learning basic Gh skills, I’m a novice using GH but it’s helped me many times.
