Internal Error

[Anonymous]

2014 ACAD mech. Get this internal error trying to open some drawings. Can open them on another computer so something must not be loaded on the one I am using. See attachment:. Internal Error: Class' AcAmgDimStd' parent named 'AcmSymbolStd' not found. What needs to be loaded ?? .. I have imported my own profile. Not sure if I should delete it and make a new one or if something else is missing.

I did not see any attachment to your forum post.  However, it appears that there could be an issue with your current profile (I have reviewed your other forum post from 4/15).  One suggestion I have is to make sure that the default <<ACADMPP>> profile is current and then open the drawing(s) in question.  If you do not receive the same error message, I would then make a copy of the default profile and build your customization up that.

Regards,
