Rhino OBJ to Adobe Dimension issues: any alternative to the Photoshop import/export workflow?

[FoolOfACook]

We have an obj made in Rhino that when imported into Adobe Dimension, breaks up into triangular faces and is generally unusable. Similar to the problem in this post: https://community.adobe.com/t5/dimension-discussions/export-import-issues-from-rhino-to-adobe-dimens...

We tried the export settings here but weren't successful.

On this forum the generally accepted solution seems to be to import the obj into Photoshop and export it again. I wanted to know if there's an alternative to this since it's an added step to a workflow that is very time-consuming?

Is there anything particular we should take a look at in the Rhino model, regarding the faces, UV meshes (although we are not applying any material in Rhino), or polygons? Or not necessarily Rhino, any 3D software that exports OBJ for dimension. Would appreciate any help!

step 1 = share the obj file Rhino spat out... its normally as simple as converting it to wavefront obj instead of whatever random junk

Blender, SketchUp, Iclone [3dexchange] or even just the default 3D tools in Windows 10 are normally finefor fixing a workflow but avoid outdated junk like Maya unless you MUST run software on old Mac systems

i wont be able to share the file in question unfortunately due to it belonging to a client, but can you explain what you mean by "converting it to wavefront obj"? as far as i can tell, rhino is already exporting an obj file. 

how can we ensure rhino exports an obj file that imports correctly in Adobe Dimension?

[Ussnorway]

in simple talk there is more than 1 kind of Obj file... wavefront is the standard [or at least one of them] but what Rhino tipically spits out is not a standard Obj

so you have to work out what [kind of Obj] file you have and then convert it to one of the standard Obj, Fbx Glb etc files that Adobe Dimension can read without errors... back before Adobe dropped 3D from there lineup Photoshop was a good option but now days you have to find another software that can do this step

I see, so a sole Rhino->Dimension direct workflow is impossible.

I'll attempt to import it into Blender (because its free) and then export as an OBJ for Dimension.

[Ussnorway]

blender should be fine or SketchUp... both of which are free yes

assuming you don't get anywhere then the next idea is to make another Obj file in Rhino with the same export settings as the clients file i.e, a different model witch you could then share for tests

Solved.

Here's what I did in the end that worked. 

Used Rhino 7 instead of 6. Used the attached export settings. Made sure to not include any curves in my export selection.

Adobe Dimension also has an opaque ground plane so if the objects aren't visible, see if they can be moved upwords in the z-direction.
