Invisible import

[user1144]

I’m trying to import an AutoCAD file in Rhino, but while the layers DO appear, there’s simply nothing visible, even though all the layers are tagged as visible. For a brief moment I thought that maybe the imported file just was super tiny and had to zoom in, but when I tried selecting everything (you know, with the mouse), nothing was selected. Any help please?

please post a file if possible.
please post the AutoCad File you want to import as well.
If you created the AutoCad File, you can also create a dummy minimal version that shows the error.

I don’t know how to do any of those thngs. Or what exactly you mean by “post a file”. Post it where? And what’s a “dummy minimal version”?

post a file

you can just drag and drop a file here in the edit window. post it / share it / upload it.

dummy minimal version

if you do not want to share sensitive data or if you have a huge file that can not be uploaded - draw some useless minimal (“dummy”) version of rectangles zickzacks etc… just some few objects that show the same problem as your original data.

the amazing answers by chat gpt:

When someone in a forum asks you to “please post a file if possible,” they are likely requesting you to upload and share the specific 3D model file or project file you are working on. This helps others better understand your issue or question by allowing them to directly examine the file in the 3D modeling program.

This request is asking for the following:

1. Post the AutoCAD File:

• Share the specific .dwg or .dxf file that you’re trying to import into another program or working with when encountering an issue. This file will let others see exactly what you’re working with and understand what might be causing the problem.

2. If You Created the AutoCAD File:

• If you made the file yourself (rather than receiving it from someone else), they suggest creating a “dummy” version—a simplified version of your file. This version should include only the minimal elements necessary to reproduce the error or issue you are facing.

Why Create a Dummy File?

A dummy file helps to:

• Reduce complexity, making it easier for others to identify the problem.
• Protect sensitive or proprietary information in your original file by sharing only what’s necessary for debugging.
• Save time for both you and the helper by isolating the error without distractions from unrelated elements in the file.

How to Create a Dummy Minimal Version:

• Open your AutoCAD file.
• Delete all unnecessary layers, objects, or details unrelated to the issue.
• Keep only the components that result in the error.
• Save this simplified file under a new name (e.g., DummyFile.dwg).
• Test the dummy file yourself to confirm it reproduces the error before sharing it.

This approach makes it easier for others to diagnose and help resolve the issue efficiently.

Let’s give it a shot… OK, I didn’t make the AutoCAD file. Here it is.
Synthesi II_plot.dwg (558.2 KB)

And this is the Rhino file after the import attempt.
plot import attempt.3dm (1.9 MB)

Amazing indeed. May I ask what exactly (more or less) did you type into ChatGPT to get it to produce those answers?

my prompts:

in a forum for discussing the usage of a 3d modelling programm, i got the answer:
“please post a file if possible.” what is meant by this ?

and what is meant by:
please post the AutoCad File you want to import as well.
If you created the AutoCad File, you can also create a dummy minimal version that shows the error.

_zoom _Extents

will show the imported data:

but be careful - the data is far from origin - this might cause problems.
it is recommended to work closer to the origin.
the lower left of the data is
x = 617972.55
y = 385199.60

hope this helps - kind regards -tom

And now I feel like an idiot. Thanks! I thought something had gone catastrophically wrong again.
