Looking for a solution of equipment and 3D software for 3D layout on vertical curved surfaces, not just typical flat horizontal surfaces.

I.e.?ÿ Something that scans the 3D curved surface, design / project points and/or line work back to that same 3D curved surface using localized control points.?ÿ Drone LiDAR??ÿ or a stationary ground solution?

Seems the current solutions are mostly horizontal or basic slow 1 point at a time vertical layout.?ÿ I.e. robotic total station with laser pointer / small precise prism layout.

Have a look at the object oriented setup in Trimble Acces 2022.00?ÿ That may give you what you need.

How are the setout points projected back onto the curved surface?

How are the setout points projected back onto the curved surface?

I would be curious about this as well. If the setout points are calculated off the model in the project coordinate system, any total station should be capable of doing the layout.

This might be less about equipment and more about how to set up the project system/control and properly position the models within it.

?ÿ

But starting from scratch? If it's a large area, a standard terrestrial scanner plus total station-defined control network for georeferencing is probably best.

If the project is not too massive in size, a scanning TS like SX12/MS60 could work. Set control and scan at the same time, resolve scans and build models directly in the project system, then calc stakeout points and send back to field.

As @christ-lambrecht said, Access can work with BIM/IFC models and even stake to them, although cylinders can be a bit tricky.

?ÿ

(Edit to add: Access does let you stake vertical lines as well, if you can extract those out of the model/cloud.)
