Hidden dimstyle or override problem

[Gouda12]

I have several drawings that encouter a problem with the dimstyle.

A dimstyle name STANDARD$0 is added by a mysterious reason, however it is hidden.

When i open dimension style I get a dimstyle name Standard and the dimstyle STANDARD$0, with both having different properties.

The problem is that when I make an annotation while selecting the dimstyle Standard I will make a new annotation with the properties of STANDARD$0.

The dimstyle STANDARD$0 can not be selected when I annotate, so the dimstyle is probably hidden.

I tried the command DIMOVERRIDE, but this didn't work. It failed already when I typed the dimstyle to override: STANDARD$0.

I tried to rename STANDARD$0 tot STANDARDtest and this worked. The properties of Standard where used in stead of STANDARD$0.

However, I can not select STANDARDtest from the annotation menu.

Is this a Hidden dimstyle or something? And how does this enter the dimension style. Can this occur while copying from other drawings?

Looks like you or someone decided to bind an XREF in that file: you probably also have layers with those characters in them too. correct?

[Gouda12]

No I don't see anything strange at the layers.

I think that might be the problem. But how do these dimstyles get attached?

Post the DWG file, let's all have a look.
