Duplication of objects in a block

[jchoppen]

I have noticed that some objects (polylines, leaders, inserted standard non dynamic blocks) have become duplicated in a dynamic block and I do not know the reason for this. I noticed it when I switched on selection cycling. 

If I look at a backup of the file (a stored .dwg not a .bak) from a few days ago there are not duplicated items in the block and the only changes I have made is to rename some layers and adjust some leaders in the dynamic block.

I'd be interested if anyone else has seen this, and possibly know a reason. 

I am using AutoCAD2020 , Windows 10 Enterprise, and a Dell Precision 44560 32GB RAM

Thanks

In older versions, older than 2022.1.2, like your 2020 is a bug between BEDIT and ISAVEPERCENT,

you should set ISAVEPERCENT to 0

to avoid further duplication.

Many thanks CADffm.

Are there any downsides to setting the variable to 0, apart from 'all save operations are full saves' (taken from ACAD help) ?.

I also see that from the Help that '..automatic saves are incremental, temporarily overriding the value of ISAVEPERCENT with a value of 90.'   Do yuo know if this means that  during an automatic save it will be set to 90 and duplication of objects could still occur ?

Hi,

>>"Are there any downsides to setting the variable to 0"

No, the only thing is - it takes more time. (if you working with big files, much edits and a really slow save-location, you will recognise it)

>>"Do yuo know if this means that  during an automatic save it will be set to 90 and >>"duplication of objects could still occur ?"

Sure! But

1. the issue doesn't appear by saving, it appears by using audit or recover such a file - Usual open command without a recover will not create duplicates.

2. for usual you don't work with "automatic saved files", for usual you are working with .dwg files which you saved - and in this case acad is using your setting (0, not 90)

Many thanks (and also a thanks for the thoroughness in you other Post that you included a link to). I haven't fully 'processed' your answer yet (I am relatively new to AutoCAD), and I was going to do some bench testing but can see that now in your other post.

I can't thank you enough for this insight!
