I am a user of this beautiful software from Moho 4, and I am very happy to have upgraded it to all his versions.
Now I have bought the AS 7 pro and I have made some importing vector eps drawing tests:
original from Lineform
imported in AS
original from EazyDraw
imported in AS
original from Illustrator (CS3)
imported in AS
the unique way for importing well a vector draw is to use the old Illustrator 8 file (but I don't have made tests with complicate draws)
OK, the eps file import is too bad, please consider to add a full svg import support.
Some people prefer to use an external program for make his draws and this limited import support is an old Moho-AS issue.
All the best
Paolo
