Thank you for a reply Dave.
As it seems you are unwilling to devote time to writing an importer, will you at any time be opening developer up to third party plugins? perhaps there is someone else willing to devote the time, if you allow them the opportunity. As you clearly point out, in 5 years time it may no longer be relevant, Photoplus and Drawplus nothing more than an unsupported distant memory by then?
"especially if the hope of an importer was truly the only advantage Affinity has for you over Corel Draw".
Not sure where you got the truly from, no Corel Draw has a whole host of advantages over Affinity, but I do understand great things take time to construct, so, being a loyal Serif customer for years now I decided to go the Serif route. Corel Draw 3 was the program I was trained on some 20 years ago, so It's got a few years on Affinity, I was prepared to give Affinity time, as I had hoped all my old work in Drawplus could be imported, but as it now looks like that will not be the case and I am being forced to start again, this time I'm going to count my losses and go the Corel route.
Best wishes Dave and once again thank you for clearing up Serif's position on this matter.
