No need to be so defensive, but...
Well it was advertised as this:
No bloat, no gimmicks, just all the tools you need, implemented how you always dreamed. Affinity Designer is a stripped back, pro-end workhorse that will always get your job done, As complex as you like, workhorse that will always get your job done, Switch between full featured vector, Rock solid vector tools, Comprehensive vector toolset, Advanced file support.
Along with all the statements I did about, it being a great AI alternative...
Now advertising as we all know it can be a funny gimmicky thing i guess..sometimes folding us in some instances. as it did me... I guess like in the fine print, and clever adverts, it did not have to mention DXF specifically, while it made you think it would.. as it did for me.
While i am new to design really knew, and not really knowing i might need it down the road like I need now, I bought it lol...
