Strange Multileader Behaviour

[pmcmahon71]

Morning all.



I would be very grateful if you could please look at the attached drawing and advise on how my trouble has come about so I can avoid it in the future.



Attached is a drawing that i have started to produce and am adding to this drawing a number of multileaders. All was fine when I was working on it yesterday, when I opened it this morning it is behaving strangely.



The multileader on the drawing has a custom arrow head, created by myself. The first multi leader (bottom of drawing) was drawn from scratch and the other 15 were copied and edited. The Annotative scale was 1:50 when the leader was created.



This morning with the scale set to 1:50 they all appear to be stacked on top of each other. Change the scale to anything else and they appear in the correct place, but still at the size you would expect at 1:50, they don't get larger or smaller. Change back to 1:50 and the all appear stacked again. If you select one with cycle selection on, it lists all 16. Set at 1:50 you can't appear to change the scale in properties.



Now I can put this right by doing the following



Set Annotative scale to anything but 1:50
select all the Multileaders
Set Annotative to No in properties.
Set annotative back to yes in properties ( the scale changes to the new scale)
Add 1:50 as a new scale in annotative scale in properties and delete the current scale
In the model turn scale back to 1:50
Arrow head and text size need setting back to correct height.

All now appear fine.



I hope this all makes sense.



Very puzzled as to why this has happened and would like to avoid it happening again.



Anybody have any ideas as to why this happened and what I may have done wrong, I suspect it is either a glitch or something to do with the copying of a multileader with a custom arrow head.



Thanks all, your time and help would very much appreciated.

You've not mentioned which ACad version. If I open your file in 2012 I only see one of the leaders while in 1:50. In 1:20 I see them all, but when selected they disappear and only their grip points show.

Doing an ObjectScale command on them gives the following error:

So for some reason it seems that the 1:50 scale has been added twice to the objects. All I can think which happened is some sort of addon did this (perhaps a lisp), otherwise it must have been some file corruption. It would be impossible to attach a scale twice to any one object manually.

Actually, it seems you can "fix" it using the command line version of the ObjectScale command (prefix with dash or minus, whatever you call it). First add one of the other scales, then remove the 1:50, then add it back and remove the other scale.

Still doesn't explain why the 1:50 was attached twice though!

Thanks for the reply.

I am currently using ACAD 2013 and have also opened the drawing on LT2103. both display the same error.

I can fix the error as detailed in my original post, but was looking for a cause so I can avoid the same error appearing again. I suspect and will test my theroy, that it may be due to the custom arrow head in the multi leader and then copying the multileader. I only think this because this is a new custom Leader, this is the first time I have used it. I have copied multi leders plenty of times previously with no errors at all. It was suggested to me on the ACAD Discussions that I should avoid copying multi leaders and create new ones each time. It could of course as you suggest be some sort of file corruption. I use a couple of lisp routines, but this drawing was created without the use of them.

If I get round this I will be sure to post back.
