If you accidentally click the wrong object, Freecad will complain and either do nothing, or do the wrong thing. Each tool has a certain number of geometric objects of a particular type, that it will ONLY work on. I will state that sometimes using the Freecad geometry tools can be incredibly frustrating. Unfortunately it seems this tool's behaviour is still unreliable in the development 0.17 version of Freecad. If you rotate or resize the first hexagon, the second one changes immediately. I wanted to show you the Clone tool rather than the copy tool, as this would create a copy that is dynamically linked to the original geometry. Place the copy to the right and below the original hexagon. Now choose the Copy Geometry tool from the copy tools, A new line shows up in the sketch, which represents in what direction and how far the copy will be placed away from the original copy. All of the geometry should turn light green. Use your mouse to select the entire hexagon, including the blue construction circle. Don’t worry about its size or arrangement, because as stated above, we will use constraints to jam it into place.

Choose the Regular Polygon tool from the sketch tools, and use it to draw a hexagon in the sketch.

You have to be careful not to over-constrain the geometry, because Freecad will throw an error message if you do, and refuse to update the geometry. Then use constraints to force that geometry into its final form.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. But you are only ever scaling the 'view' of the 3d model, you do not scale the 3d model itself.The following is a tutorial for making a hexagonal grid in Freecad, that is parametrically controlled and suitable for 3d printing. You move and scale those views on the TechDraw page so they suit your real world requirements and then print the page. If you want to print technical drawings in today's FreeCAD, you first create the real size 3d model, then you push views of that 3d model onto a 2d page using TechDraw workbench (note, TechDraw not the older now deprecated Drawing WB.).

#Freecad scale series#

Modern CAD like FreeCAD actually creates a 'real' model of the object not just a series of line drawings showing a view from different directions. Those drawings are just that, just a drawing, with enough information so that you can interpret what is intended to be shown. The scaling that the original poster was talking about is an old out of date concept, like drawing a technical drawing but in a computer rather than paper. Normally you set the scale to 1:100 and go from there, or as with Sketchup, you enter the dimension you want and then blow it up to work on it.Ī seven year old topic! FreeCAD has evolved beyond all recognition over that time.Īs the others said, modern CAD, you model your object in real size.you then zoom the 'view' of it so that it fits on your screen, but the object remains in its real size.

#Freecad scale full size#

Hi ickby, I too am just starting with Freecad, but cannot see how you can draw a fish tank 4,000 mm long by 1250 mm wide full size and then scale it down.

I'm not overly familiar with draft workbench, but I would say: you don't set the scale! You draw everything the real size and when you put it on a drawing (drawing workbench) you can set the scale to fit it on a standart paper size.
