polylines broken into lines and arcs (part of circle)

[rcook]

I am working on a drawing and do not know what happened.  I had arcs and straight lines (all polylines) that were attached and are now broken into seperate lines and arcs (that show to be part of a circle).  I can only munipulate the arc as circle/elipse (it shows the part of the circle that is not drawn in addition to the arc that is drawn.  now some of my arcs do not connect/line up with my lines that they were previously connected to.  I also noticed that my text with multileaders are now single line texts separate from the leaders.  Not sure what happened, but it obvioulsy screwed things up.  It appears to have exploded all entities or something.  Not sure if there is a way to repair the damage done but has anyone seen this and is there a fix?

Looks like something has ended up doing an EXPLODE ALL.

Unless you are still in a session (where you could undo your way back out of trouble), the save after that inadvertent action will have saved the file, and if saved again after that will kave lost the BAK file as well.

About the only way would be if you have a backup system that would allow you to recover it from a from the previously saved version, you will have to re-join the elements back into polylines.

As to how it happened, it could be a mistyped command, or a custom/standard routine that has been aborted and left things in the state you find them, rather than rolling back out to the state before it was run.

is there a chance you have a .bak file saved any where from before this event?

It was a couple of hours bfore I noticed it.  At one point I had to close the file to work on another, hence, original backup was lost.  Could go to the previous day backup but would lose some 7-8 hours of work.  Such is life. live and learn.  Just wish I could pin point what happened.  I have never seen an arc change to part of a circle before where I lost my ability to manipulate it as an arc.  could only manipulate it as one would a circle or elipse. Someday I will run into it again.  Thanks.

Hello Robert;

Something I used to do when I was a drafter (and have seen orther drafters post about recently) is doing a Save As every hour or two, naming the file something like <filename>-a, -b or -1, -2 all during the day in case I did something wrong, or had some kind of system issue, etc.

That saved my bacon a couple of times, and doesn't take long in the greater scheme of things. I started doing this when I lost a file that I had been working on for 2 days. My network admin said no backup for either of those days because the backup server was down and was awaiting parts. I had to completely re-draw 2 entire days of work, so I feel your pain.

I understand that this doesn't help solve your current problem, but might help keep it from happening again, especially if your system is having issues.

Another thing I typically recommend is exporting your AutoCAD settings to a file and uploading them to, say, an A360 account so you can get them back if there is a cataclysmic event that takes down your entire system.

A donut is a polyline with 2 segments with bulges.  It probably was drawn to hard code a lineweight, like for a callout key.  Once you explode, all widths are gone, leaving you with arcs.

It's redraw time.  Be thankful you only lost 8 hours.

PEDIT command can put back an exploded Pline back together. MPEDIT command, if you installed Express Tools, can work on more than one broken Pline at once too.

Steve,

I save about every hour or so and about half the time I do save as another file but sometimes it is just hit the save as everything looks okay. Go figure. Thanks.

Guess there is probably no real solution to the issue & have not backup, just curious what I did and how to repair the arcs without having to redraw them all.  Thanks to all.

Chances are that somewhere along the line there was an inadvertent explode all.

If you are using both hands, then mistyping a command can do this. For example, the standard alias for explode is X, and the standard alias for stretch is S. If you are not careful, you can inadvertently press X instead of S and get things wrong. Not saying this is what happened, just one possibility. It could even be a routine (standard or custom) that has not undone correctly and left things like this.

Without a backup, the only way around it is to use PEDIT and  join the arcs and lines back to their respective polylines. You can gather a large number of elements together quite easily by windowing them, being careful where two segments might share the same end point, but be for different polylines.

Things like this happen. It's a bit like when I worked for a company that had an old NEC APC (around 1985) with two 8" floppy drives (no hard drive) and the only way to reformat a floppy was with a large powerful electro-magnet. One of the guys decided to "reformat" some disks only he used the electro-magnet right above the top drawer of the desk where all the floppy disks with data on them were kept. Well, the magnet destroyed the data on quite a number of the disks in the drawer and he had to re-create the data files he destroyed.
