Hi! This is blog. Here, I'm posting interesting things, feature announcements, and whatever about Lattice.

Lattice2 was ported to support Python3. Thanks to @loooo and @wwmayer for their help!

I called it Subsequencing. Say we have a link to an element in an array (compound). Subsequencing it means extracting all the elements like the one selected, from all children of the array.
For example, we have a sketch with a few polylines. Subsequencing Vertex1 will yield starting vertex of every wire (because Vertex1 of compound happens to be Vertex1 of first child, and every Vertex1 of each child form the subsequence).
Currently, subsequencing is implemented for SubLink tool and for Attached Placement. This is happening in a separate branch, MultiSublink. As soon as I'm happy with the code, I will merge the branch into master Lattice.
There is a plan to make a derivative of ParaSeries, built around subsequencing.

Recently, Attached Placement feature of Lattice was broken, because attachment was ported to use the new Extension architecture. Today, I fixed it, so Attached Placement now works in both old and new FC v0.17. However, the files made with FC older than v0.17.9177 won't work in v0.17.9177+. So, I strongly advise you to update to most recent v0.17, if you are using one already.
Lattice in FC v0.16 should not be affected, since Attached Placement feature doesn't work there at all.
PS. Merry christmas, and Happy New Year!

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".

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.
