In Freecad sketches, the workflow is like this: There are other toolbars, but these are the important three. In the sketch view, you have three main toolbars, one containing all your sketch tools (To the left in the second row in my setup), one containing all your constraint tools (To the right in the second row) and finally one containing your copy tools (to the left on the bottom row). How to use the Part tools to do an Extrusion and a Boolean Cut.How to use the Array Draft tool in Freecad to make regular repeating patterns, and finally,.How to use the Draft Workbench in Freecad to make measurements, including a trick to link those measurements to the actual geometry, enabling measurements to be adjusted as you change your model.How to link geometry between different sketches (so you can ensure that two parts are the correct distance between each other).

How to use constraints in Freecad sketches.Parametric modelling using Freecad spreadsheets.The reason I’m presenting it this way, is because this tutorial will demonstrate the following advanced Freecad features: If you just wanted to make a single hexagonal grid, you could do it faster than the method outlined below. What we want is a Freecad file that allows us to type in one measurement for the size of the hexagonal voids, and the thickness of the walls between the two hexagons, and Freecad will calculate the final mesh for us automatically. The following is a tutorial for making a hexagonal grid in Freecad, that is parametrically controlled and suitable for 3d printing.
