Lines Too Short
Unfortunately it is not possible to have detail lines as fine and as small as 0.1mm or 1/256inches in Revit.
Such fine and precise tolerances are far better detailed using Inventor.
Inventor is far better suited to this type of design detailing.

Couldn't agree with you more.
Let me explain the situation:
It's an isometric view of floor sheathing on wood joists. It's a detail, so we want it to be "revit-ized" for future changes and whatnot. First, I tried exploding the cad import so that the objects were all lines that could be easily manipulated, unfortunately, this got rid of all of my nail symbols because the arcs that made up these components became too short for REVIT to use. Then, I tried, as you suggest, to create the same nail symbols using a detail component. But obviously, there is a minimum size that needed to make them. Essentially, my compliant is that now all of my nails look like really big holes instead of nice neat little round dots (See the image below). Not the end of the world, but just wanted to get the thought out there in case something can be done about it.
Accepted solution
I understand your fustration, however Revit is behaving as designed, however I can recommend submitting an enhancement request.
There are currently two online forms for customers to submit enhancement requests.

I think the limit is around 0.8 mm.

Please mention Revit version, especially when uploading Revit files.
I can only speculate....
I think it has to do with the internal calculations and memory. The more extremer the numbers (large or small) the more memory you will need to store them and the more calculations you have to do. To keep the program run (relatively) smoothly they might have decide to set limits.
Also take into account that the first Revit release was around 1997 or so. Computers were much slower then. Because this part is the core of the program making modifications to it is a difficult process without breaking backward compatibility.
Something similar is happening with the larger numbers. Revit used to have a maximum radius of 2 miles. Later they managed to increase this to 20 miles.
If you start to work around these maximums you will start to see odd behaviour.
But maybe something form Autodesk can chime in.

Maybe should have used the term forward compatibility. What I mean is that this touches the core of the program. Modifying this code will take a big effort, certainly while being able to open older files.
While computers have 'evolved' it still remains true that when values get more extremer it requires more memory and more processing power to handle this.
It is correct you can create lines smaller than 0.8 mm (in a family).
-Start a new family
-Draw a line of 10 mm.
-Use the scale tool and scale it 1/200th. Now you have a line of 0.5 mm and Revit does not complain.
-Now try to copy this line. Now you will get a line too short error.
So yes, you can create lines shorter than 0.8 mm in a family. However I would not use this 'trick' as it is uncertain for me if this will not cause issues in a project or in future Revit versions.
