I've had this problem before with mtext plotting out thicker than others (true type fonts only), as have many others, and solutions have been posted - eg move it to z=1, then bring it back to z=0 and the dview solution.
They've always worked - until now. Attached is a real hardcore example (I've deleted everything except the mtexts). Tried both methods, audited the file, purged, etc. but still the problem persists.
One method I came up with was to explode the mtext to dtext, then do the z=1, z=0 trick, & it works. However I'm left with a bunch of single line text & that's not acceptable.
Please, all you ACAD professors, have a look & see if you can come up with a solution.
Thank you.
