Sharing dimensions

Continuing my adventures in FreeCAD, I now had to design a top to my Raspberry Pi enclosure. The FreeCAD people were friendly and told me to checkout spreadsheets.

However, since I already started down another path, I decided to name my constraints. Something I picked up from a random YouTube tutorial I cannot seem to find again.

Having done so, I can then refer to the name in a formula and thus, reuse the old value.

Now, let’s see how the lid will fit. :-)
