Importing .obj into ArcGIS Pro

StevenFernandez — Thu, 06 Sep 2018 18:35:44 GMT

Hello,

I've have been at it for 2 years now and I can't for the life of me import a 3D model generated from different modeling applications. I've tried straight from Geomagic, which always has axis issues, no matter what rotation I apply. I've tried from mesh lab, same issue and I loose the texture in that process. Anyone have usable import instructions for .obj or 3ds?

Thank you,

Steve

In ArcGIS Pro 2.2.x, there's the Import 3D Files geoprocessing tool that supports *.3ds and *.obj files for import. It comes with the 3D Analyst extension.

Thanks Robert,

I'm way past that point. When I import the models, they are never in the right orientation. Sideways, upside down, inside out. I've tried to reorient, translate and change the axes on them in the various modeling applications, but no change. If there was a flip or rotate around the x or y axis, I'd be set.

Gotcha - thx for the update. Have you contacted anyone on the 3D Support Services Team about this issue. May be the next step to take.

Hi Robert,

So ArcGIS Pro rotate tool does let you rotate around the x and y axes. For me, it doesn't show the tools options until I pan around a bit.

However, the tool didn't work like it should. I'm going to post a new thread based off this problem.

How do I contact 3D Support Services?

Thanks,

Steven

Steven - when you call Esri Support Services, describe the issue and ask to speak with the 3D Support Team. They should route you correctly to a 3D analyst. All the best!

Hi Robert,

I wish. ESRI only allows one authorized caller for our entire site and it's not me. I've been trying since 2010. I'm left to solve all my problems on these forums. I get 1 in 5 solved. Usually move on to another software.

Thanks,

Steven

Has any progress been made here? I have a georefrenced .obj and when I use the Import 3D Feature tool (with the correct coordinate system) it displays in the wrong location, as well as being upside down. Any thoughts?

Hi Zach,

I had to rotate the model in Sketchup, then bring it back to ArcGIS. I have had the upside down issue as well. One that was inside out! I think the rotate tool is new and has not been perfected. If you don't have Sketchup, you can rotate in Mesh Lab too. And it's free.

Hope this helps.

As for the location, that depends what coordinates the model has going in. Does it have the same coordinate values going in? Or do you have it in a WGS UTM or something like that, then trying to project it on the fly? That doesn't work. Either way, you can move, scale, etc with the 3D editor.

Thanks for your response. Its inside out too! I use Pix4D to process the data and it puts it on a state plane coordinate system, so it should at least be accurately georefrenced. I want to try to avoid using the 3D editor tool to manually move the mesh around, so I don't loose accuracy.

Thanks again!

Hello Zach,

If you are using Pix4D to process the data you should be able to output it in the OGC I3S format. Which is one of the output formats available along with obj, fbx, ply and osbg. I3S slpk format is read naively in ArcGIS Pro, ArcGIS Earth and can be published directly to an Enterprise or ArcGIS Online organization account.

Hey William. That worked great!! The only thing I did notice is that my mesh is a WGS 84, while my map is in state plane. It all matches up perfectly, so I'm just assuming there some kind of on the fly projection going on?

Thanks again.

Re: Importing .obj into ArcGIS Pro

WilliamMorrish — Fri, 19 Oct 2018 18:40:30 GMT

Your welcome Zach

Yes the default I3S SLPK output configuration is to publish in WGS 84. As most scene layers are published and viewed in the ArcGIS Online web scene viewer or in ArcGIS Earth.

In ArcGIS Pro there is on the fly projection being implemented. in the the web scene viewer though. All of your layers will need to be in the same coordinate space.

It is possible to chose the output coordinates of your I3S SLPK in the preferences in Pix4D. If you dig a little deeper you will find there are a myriad of ways to customise and optimise your Mesh output.

Okay, so when exporting as a SLPK, the mesh, by default, is converted to WGS 84, got it.

Also, I am trying to view the .SLPK online so I upload the it to my online account and try to publish it as a hosted layer from there, but keep getting a message "There was an error publishing the service." Thoughts? Could It be because I am in a ArcPro trial?

Thanks again!

Try using the Export to 3D Web Scene tool in the 3D Analyst/City Engine Tool Box.

The Export to 3D Web Scene tool seems to only be in ArcMap, not ArcPro.

Depending on the level you have in your online account your publishing rights may be limited. Are you part of an organizational account or have your own personal account with limited publishing privileges?

My Issue was the title of my SLPK had "()" in it, so iwas able to upload it, but not publish it. Silly mistake

You mentioned that when exported from Pix4D to an SLPK it is converted to a WGS 84, but when I try to add it to Arc Scene online, I get "Scene Layer has an unsupported vertical coordinate system. The vertical units of the layer must match the horizontal units (meters)."

So only the XY is converted, but not the Z coordinate system? Is this something that needs to be edited in Pix4?

Hi! I have a question regarding the 3D obj import to ArcGIS Pro. I tried to import using 3D analyst tool and I can see the layer in the contents, but it is invisible.Do you know what might be the reason? Thanks.
