Hi! This is blog. Here, I'm posting interesting things, feature announcements, and whatever about Lattice.
August 22, 2016.
Array tools just got a new capability. Now it is possible to align an array on an edge it various manners. Plus, I added a few presets as dropdown toolbar button "LinearArray".

August 22, 2016.
Now, by default, shallow copies of shapes being arrayed are made. As a result, speed of creation of populate features, as well as the arrays themseves, was significantly improved.
But. To notice the improved speed, you need to work with large arrays. And you also should disable selection highlighting/prehighlighting in FreeCAD preferences, as highlighting the newly created array takes much longer than creation of the array.
These changes will have an experimental state for a while. If you notice something strange, you can try switching back to old deep copy by changing 'Copying' property of Populate features. Then, if shallow copy proves reliable, I plan to remove 'Copying' property.
I hoped it would decrease project file sizes. But it doesn't. Unfortunately.
