You want to export your drawings from PDMS to dxf format?
If yes, then there are already some threads on this forum about it...
Draft isn't a very easy module, so you should consider applying for a training course.
Do a search in the forum and I'm sure you will find what you need.
Why do you always need to export to 'DXF'....? Why dont you use 'Autodraft? this way you convert draft drawings directly to autocad and edit them as well.
I setup everything nicely in draf admin, from symbol, representation, style and label.
I already put PDMSfont and Autodraft into my autocad 2014. But when i convert from draft to drwg, the result is ugly. All my symbol is not appear in my drwg. All the leader line for tagging not shown. all text have box arround. And line weight is not same. Simply say, the drwg created in draft are not same in Autocad output. Any tips how to solve this problem?
