Hello everyone. Could somebody help me in one question? I need to set coordinate axes for my 3d scan. And continue to work with it in Rhino. I tried to set xyz coordinate, but it is not working. I’d be very grateful for your help!
Hi Petr -
I’m afraid I don’t know what that means.

Hello Wim. I need to orient a 3 d scan in space. How I can do it in Rhino? Thanks!
If you already importedd the file, one way is with the Gumball.
In addition to that, there are a few useful Align commands.
What software did you use for the post processing of the scan?
Another way is to use the Rotate command.
-wim
If you’re looking for the typical commands usually used inside scanner software,
orient
or
orient3pt
should do the trick.
Hello Martin. Thanks you for your reply! I’ve used CrealityScan program. Then exported stl file to Rhino for making a solid body for late editing. But I couldn’t orient the mesh by axes coordinate. I’ve tried set XYZ coordinate it didn’t work. The program asked me to set a point on the mesh, but it is a mesh I couldn’t set a point. I didn’t find any video to helping in this problem, decided to ask on the forum. Later I did it in Mesh Mixer program, after found out one video. But it is pity that Rhino can’t do this simple step!
I’m working with scans on a daily basis in Artec Studio and Rhino 8. I align whatever possible in Artec Studio but Rhino can certainly also be used to align a mesh…
If you cannot snap to the mesh, maybe you have Osnaps disabled. Can you post a screenshot or screen recording of what’s not working?
Rhino can align a scan, but perhaps not using the exact same method you have used in other software. I routinely import and align large scans.
Rhino does not have a “setXYZ” command. Do you mean SetPt? If so it has a different function and is not used to move or align an object.
Move is the Rhino command to move an object to a desired location.
You can select mesh vertices and ponts on mesh faces.
To select a mesh vertice make sure the Vertex Osnap is turned on. The select the desired vertex.
To select a point on a mesh face use the Mesh one time Osnap.
Hi David. You are not right, there is a set XYZ coordinates command in Transform bookmark. That is only one piece of advice given online. Thank you for helping me. It would be perfect if someone make rev engineering video for Rhino (step by step). I didn’t find one. Maybe this program can’t do this, or Mcneel team don’t interested it.
Cool Martin, I wish I could do it too. But I can’t find any info about rev engineering in Rhino. I gave up Fusion in favor of Rhino, but I regret in these cases. I wanted do it ,but don’t know how and can’t find any info helping me. Thank you Martin!
The first step would be proper alignment.
And then about reverse engineering. If you’re looking at a tool which let’s you set creases and fillets and what not, you might have to look at Geomagic or so…
If you don’t need the 100 % equal and wish to maybe also redesign or improve some of the details, Rhino is certainly capable. Look into Shrinkwrap, Isopod and QuadRemesh.
“Set XYZ Coordinates” in the Transform drop-down menu is not the name of a Rhino command. It is a short description of what clicking on it will do.
Click on “Set XYZ Coordinates” and the SetPt command will start, which can be seen by looking at the command line.
SetPt is not what you want to use. If you use setPt so set one coordinate value you will transform your object into a planar object at the specified coordinate value. Use SetPt to set two coodinate values and line type object will result. Uset SetPt to set three coordinate values and your object will collapse to a point.
@Petr_Tikhonov This is not true. Rhino can orient imported point clouds and meshes from scans. Use the Rotate, Move, Orient and Orient3Pt commands. Learn how Osnaps including one-shot Osnaps work and use them.

Yes, Martin I’d tried Shrinkwrap and QuadRewmesh, then Subd and converted it to NURBS, but result was far away from the original. But from the beginning I have encountered a problem orientation the mesh. That’s why i asked a help. I’ve understood that this program is completely unsuitable for 100% copying. I recently bought a scanner and was already dreaming about scanning and postprocessing in Rhino. A terrible disappointment awaited me! Geomagic costs over 20k, which is not for me. Maybe you can advice me something. Thank you Martin so much!!!
Why don’t you share at least a screenshot of your scan?
That’s only true if your goal is exact reconstruction of nurbs with fillets.
As soon as you’re dealing with complex freeforms and parts which are going to be 3D printed, it is a whole different story as fillets become less and less relevant.
Thank you David, I’ve oriented it handly. Thanks again!
Are you going to CNC machine the tooling?
There are two reverse engineering apps that are in the “reasonable” price range, although significantly more than the the Rhino license.
Take a look at Cyclops3D and Mesh2Surface.
I haven’t used them myself but they have some functionality that is similar to Geomagic at about 1/10th the cost
Maybe there are users here that are familiar with these apps and can offer some insight.
