I have the same problem. In my drawing my dimension has a square instead of diameter symbol and my GTol has 2 squares instead of diameter and MMC symbol. These both look perfect in the part. Using Creo 4 M020
It's strange because all my other dimensions are fine. The only difference on this one was I followed PTC's video on how to add the C datum feature symbol to the datum reference frame.
I have the same issue. Last week on Creo 3 the angle and direction arrow was there. This week on Creo 4 I create a new sheetmetal part and I get 2 squares where the angle symbol and the direction arrow are supposed to be.
I have attached 2 pdf files that show the differences.
I got an answer back from PTC Help. Below is the response that I got and it seems to work.
This issue has been reported to R&D as SPR 7267986, however you can try the following work around.
Change option from “Symbol_font ASME” to “Symbol_font Legacy “
