1. It does not obtain dimensions for all arc objects.

2. It does not obtain the dimensions of all polyline arc segments.

1. It does not obtain dimensions for all arc objects.

2. It does not obtain the dimensions of all polyline arc segments.

(command "_.dimradius" "_non" p1 "_non" p2 "")
        (command "_.dimarc" "_non" p1 "_non" p2 "") ;

 

 

 

Your code, ready.

I've disabled some lines of your code that weren't working and added some new lines of code.
I hope this helps.

@GLAVCVS It may not function correctly, possibly due to the direction(clockwise or counterclockwise) of the arc or because it does not meet the point on the arc.

The DIMRADIUS and DIMARC commands are very fickle. I've used them very little so far. But thanks to you, I'm a little more familiar with them now. 🤓
So I guess I owe you a favor for that. 🙃

Yes.
Part of the problem is with arcs whose initial angle (group 50 in the database) is greater than the final angle (group 51 in the database). But you also have to specify point p2 inside the arc so that it's drawn in the correct location. I had to spend a bit of time figuring this out.
