Rhino mesh into AutoCAD but latter doesn't support meshes

I am astonished that AutoCAD doesnt support meshes, it has been around longer than Rhino.
I have sent someone who runs just AutoCAD a mesh to work to in the same manner as I will in Rhino, someone who is yet to even make a cube, using projection and old school methods of drawing up plans, 9h for construction lines etc ! try to encourage him to use photogrammetry rather than a day drawing and measuring one item when I have taken a few hundred pics and done ten…and find that his AutoCAD cant even show a mesh.
I read of AutoCAD gizmos converting obj to dwg, not sure thats a step fwd though.



It does. See for example AutoCAD 2019 Help | About Creating 3D Meshes | Autodesk

As this is an Autocad topic, not Rhino, you should probably take it to an Autocad forum…

It would not hurt to reiterate it here for any new users … using a mesh in AutoCAD is very inefficient and should be avoided, although technically its not impossible.

Additionally, a mesh format in many applications is almost useless to use as a basis for a dimensioned drawings for a number of reasons.


It may be possible to convert your mesh with color texture from photogrammetry to a colored point cloud.
The point cloud may be more easily used in AutoCAD, assuming one is using a relatively recent version within the past 5 or 6 years.

Can you share the mesh? … if you can’t share it here can you PM me … I think we have exchanged files previously.

I think posting this AutoCAD issue should encourage newcomers to consider Rhino !

it (2019) talks of creating meshes, but when I google import meshes all I get is buy this addon etc.

Perhaps there is a totally different AutoCAD for working in solids and meshes.
he is purely 2D and everything drawn in a traditional 1940s way.

Exporting cloud points is not suitable as I want him to do what I do…
After a rhino struggle to see what I am doing when orienting the mesh, (other thread on grey mass of triangles obliterating view) I work successfully with meshes in creating accurate drawn solids and plans.
making sections, tracing outlines etc, placing details using ortho., tasks that would take a day to do on site.

Are you saying that wouldnt be posible in AutoCAD ? either accuracy or displaying as I do ‘SetObjectDisplayMode’ rendered whilst in shaded mode ?

I see mention of addons, purchased or otherwise for AutoCAD. he may well cry shy of such.

I just wish Rhino was natively at ease with meshes, (must post example to Halo)

Cdordoni, I cant share the example as its done with permission for our eyes only.
I have others I could share, let me have a look and hI can PM you with it. I would need to transfer it with wetransfer so need your email address, can I get that via a PM, will try.


Unfortunately that is a tough point for a lot of CAD apps. I know its possible to create vector lines and curves from a mesh in Geomagic using sectioning tools but it does not give you the drawing functions like you would get in Rhino or another CAD app. So then you would have to export the section to use in Rhino.

As far as free apps are concerned, I believe Cloud Compare can export the vectors from sections that could be be imported into Rhino. Its been a while since I have tried this in CC so I would have to do it again to give some instruction.

I dont section in another prog, I import mesh into rhino, then use section tools, project lines, and so on to get sections and then refine and average them to get the ‘original’ shape.
I want him to do likewise.

point cloud would deny that.

but will autocad 2019 import a mesh and render it with the jpg created with the obj export ?
Just as I do in Rhino rendered mode as explained prior.

talk of turn obj into dwg, is that the solution to see a mesh object with texture on it, so as to then do sections, trace it, project lines at it etc ?


Unfortunately its not possible to import a textured mesh into AutoCAD, thats why I mentioned a colored point cloud as a possible alternative.
Small details in the texture probably would not be visible when it is converted to colored points.
