Purging A Tree Ghost- an unselectable entity?

[mattwaddington]

I have drawing that contains some sort of unselectable entity that I can't delete or purge, which I believe came from a tree symbol I downloaded years ago (thus the tree shape), and now seems to be in any drawing that contains that symbol, and if I copy even a single object (say a line) from a file with this odd entity in it to another clean file, it comes with it.  I cannot get rid of it once its in a file, even if the symbol is deleted and purged.

I am attaching a file with this entity, and I have stripped the file down to a single layer (0), which is unfrozen and unlocked, and has no defpoint layer, and includes only a circle object with a radius of 1.  I have purged and audited it a ton of times, and done everything I could think of, but the "tree" remains. The tree shape has a size, is visible in a view port in paperspace, and is a "real thing" - not a issue with my graphics card. I am using Autocad LT 2024.

I have some large site plans that have this in it, and I don't want to send them to any of my consultants with this ghost.  The usual strategy of copying all the objects to a clean file doesn't work. For example, if one copies the circle below into a clean file, without "selecting" (which you can't anyways) the "tree", the tree comes with the circle into the new file. Its like some weird ghost thing, or worse. I suspect the original tree symbol was made in a program other than Autocad, and is associated with that, but I have no idea really.

Any help or suggestions would be very much appreciated! 

Here is a screen shot. Circle has a 1 unit radius. Tree is unselectable.

If I zoom in on the lines of the "tree" the dots remain at their spacing, but if I regen, it tightens up- here's a zoomed in view of the line after a regen.

Thanks!

Thanks for looking- that surprised me!

But the tree is still there I think-  I just rechecked, and you don't see it when you open the file,  what one has to do is select the circle (or any object if there were others), and the tree will appear. Try that and see if it appears, I think it will.

I also just noticed that a  linetype comes with this entity called "ACAD_DYNDIM_LINETYPE", which is not one I created or use.  But maybe its a clue. I can delete the linetype, but as soon as one regens, the linetype comes back. Its really weird.

Let me know if you see the tree when you select the circle. You'll also see that if you copy the circle only to a clean DWG, the tree comes with it.  What's going on?

Thanks for taking the time to look at this Pendean.

I can't explain what happened- as I had already purged that wayward line type multiple times,  seen it no longer listed in the loaded linetype list, then regenned and had it come back.in the list, and as an entity. Like it was a viral thing somehow, permanently in the drawing, and attached to every object in that drawing. And found that they stayed even when I closed and reopened the file.

However, I closed Autocad, and now in reopening the  test files, the entity has gone. I can't replicate it. So- I guess the problem solved,- but it required closing down AutoCAD (I think?) to do it? Doesn't matter, just odd.

I think your diagrams also noted that there is an update I should do to 2024- which I will do (I only downloaded 2024 recently). Thanks again for the time spent-

@mattwaddington Restarting your computer remains the #1 problem solver for the last 30+years for most programs and operating systems. This should always be the first thing you do to address an issue moving forward before you expend any effort trying to "fix it".

Software updates are always important. Always.
