![]() The sketch will be hidden, so you will need to select it and press the space bar to make it visible again. Then you can use the Undo button to undo the Extrude or just delete it in the tree view. It will give you the area of the face and some other information, too. ![]() You can install this macro using the addon manager in the Tools menu. Then select the top face and run the SimpleProperties macro. Overall: I have used FreeCAD as an hobbyist who has no availability for payed cad softwares, to produce models that I later 3D print.The biggest pro of this software is the number of features implemented and totally free, which makes it the best unrestrained free option for who requires a CAD or a FEM software but cannot pay for it, but unlike another 3D software, Blender, that despite being. There is a good pdf on using the sketcher here:Īs to how to get the square area one way to do it is to temporarily extrude it with the Part workbench extrude tool. They might do some unexpected things, but I promise you they will always be 90 degrees. You could, for example, constrain the angles to be 90 degrees, then they will not change from that no matter what else you do. You can constrain your sketch with the sketcher to be like you want, and if you get it fully constrained, then modifying a value, such as distance to door will cause the rest of the sketch to conform to that new dimension. You should probably use the sketcher instead of draft tools. How would the dimension follow that line if I decide to move one or both points of that line? How would I attach the dimensions to the actual corner points? I tried an empty document, draw a line in Draft, added dimensions to that line while holding down CTRL. Or maybe I decide just the left wall is 3m from now on, that would lead to non-90° angels. Drawing creation: FreeCAD includes tools for creating 2D technical drawings of 3D models, such as dimensioning, annotations, and views. Like if I decide the width from door to window is not 2m, but 3m, I would ideally just change one value and the rest of the drawing (the corners) would just follow. Now my idea to actually fix the dimensions later on would be to set some sort of constraints. How would I fix the location of the points that represent the wire? I supposes here and there I have to say: the lines leading to that point have an angle of 90°. If there is indeed some snapping, it is very weak. The example says the mouse would snap to the corners, which would result in an exact drawing of 90° angles. Then draw a wire to get the two walls on each side. If I understand the kitchen example correctly, the way to achieve the initial structure is to draw a bunch of rectangles and lines. FreeCAD Step by Step: Learn how to easily create 3D objects, assemblies, and technical drawings with FreeCAD (FreeCAD 2D/3D CAD for beginners & advanced. how can I set constraints in a 2D drawing, like the simple kitchen example in the Wiki? can FreeCAD actually calculate the area size of a polygon (a room), if so how would I do that? The goal is (still) a 2D drawing of rooms with two-digit number of corners, see my posting history for an example file from July 2018. Guess I need helping hands, so please bear with me. I have a hard time following the 2D tutorial, and achieve the very same results as shown in the Wiki.
