Now that the new updates at MyHeritage have taken effect, things have changed a little bit.
There are two ways to create your family tree online. One is to create a family tree in Family Tree Builder and then publish it to your family website. The other way is to create your family tree directly online.
If you have created a family tree in FTB and published it in the past, then you will have the option to download the tree - just as Sassafrass so rightly indicated.
If you created a family tree directly online, without using the Family Tree Builder program, then you will not be able to download it at this time.
This option is yet to be implemented on the site.
We are currently working on collaboration between online trees and FTB trees. It is a major issue here that will be available in the near future.
The main features of the new version 4.0 are the following: Maps
Using our maps, you can explore your family's origins, gain a better knowledge of your family, and enjoy all the benefits below: · Fix place names according to smart suggestions we provide and improve your data · Map your entire family tree, or any portion of it, or just one individual · Map birth places, places of residence, other particular facts, or all facts · See all people, events and photos associated with any particular country or place · See all places of importance in any person's life, and trace immigration patterns · Find any place in any language on the map Photo albums
Organize your photos in albums for your convenience. When you publish your family tree to the web, the album structure is preserved in your family site.
This makes it much more convenient to manage very large photo collections. Inside albums, use drag & drop to change the order of photos. Also use drag & drop to copy or move photos between albums. You can even drag photos from Windows into Family Tree Builder in the new version. Slide shows and screen saver
You can also view slide shows of any photo album that you create or for all photos. In addition, Family Tree Builder now comes with a Screen Saver that shows this slide show for any or all of these albums. And there are many other smaller but nevertheless important improvements in version 4.0. For example, it can now restore a family tree you published to your family site, including its photos! So publishing your tree now fully means backing it up. FTB 5.0 is planned to be released with synchronization technology. You will be able to edit the tree both from FTB and from your site, download changes made on your site to your FTB tree, accept/reject changes to the tree made by your site members and more.
If your online version is the most current, you could try downloading it off your website by going to Family Tree>Summary>Download, then opening it in Family Tree Builder. That seems to have worked for me before. I've found though that it's best to only edit from Family Tree Builder program, and then publish your updates every time because (as of right now) there's no way to synchronize both versions without copying over the other version . . . at least not that I know of.
