SetWorldOrigin is a new command in Rhino 9 WIP which changes the world coordinate system. One use of this command is to revise the world coordinate system to remedy “far from world origin” situations. I’ll be using it to revise the world coordinate system of models when my understanding changes of what the base coordinate system should be.
SetWorldOrigin does more than merely change the world origin. It also allows for redefining the world x, y and z directions and scaling the entire model. It has options to update Model Views, Named Views, Detail Views and CPlanes to the new world coordinate system.
So far SetWorldOrigin has been almost invisible with no annnouncement on this forum. It isn’t documented in Help yet, and the only two mentions I can find are:
The question I have is, once you use the command and change the world origin, what happens when you need to import another geo-referenced file to match the first one? (for example a neighboring tile from a DEM download site)
… or what is the export procedure like if I want to export with the original position of the model?
I really like the potential of this, as it has been really cumbersome to adjust the location of a far-from-origin model. And work together with other AEC fields in sharing geometry.
please describe the logic in more detail. i need something like model point origin which has relationship to world origin so that geoemtry is calculated in respect to model point origin (to avoid ffo problems) but rhino shows and exports and imports geometry with large world coordinates. is this tool something like this or completely different? @davidcockey
