I am converting dft drawings to dxf and it doesnt convert hole callouts for example it doesnt recognize M8 hole, it just puts (diameter mark) 6,65.
Also the drawing number and name changes their font size and location. I have tried changing some options that SE gives you before you save dxf, but it doesnt change anything.
Conversion to DXF and subsequent conversion into another program is tricky in regards to text and symbols due to font mapping. For instance, every font has a different design of the characters and different spacing. Some fonts display symbol characters instead of text characters. This being said, when you save out a DXF, it has certain fonts assigned to the characters however when you read it into another application, it may not have access to those fonts (different PC) which means it substitutes a different font, and it may as a matter of fact substitute it's own fonts as standard practice. This is especially true when using annotation in SE such as Feature Control frames and the GD&T symbols. Often they translate into AutoCAD as letters as it substitutes the font and all it knows is the ASCII character number, but does not know the graphic that represents that character...
You can take measurements from the converted drawing... Why can't you? Conversions are never perfect. What should be accurate is geometry, beyond that you will have to play with font mapping to get the rest correct and might have to provide Solid Edge fonts to whomever is receiving the ACAD file to be able to view it correctly.
