Add a vertical distance constraint between the two endpoints of the horizontal construction line. A lot of the details are clearly more oriented towards products that have few but rather complex parts – not so much a woodworking project that mainly consists out of simple boards. When your model cannot be printed or milled directly by a machine, for example it is too big (a building) or it requires manual assembly after the pieces are ready, you will usually need to explain to another person how things fit together. Retr3d uses python and FreeCAD to 3D model printable parts for the construction of more 3D printers. To make sure the slot is lined up with the center, just draw a construction line from the center of the circle, constrain one endpoint to be. SketchUp is an Architectural Design Software developed with an Architect's needs in mind. Set that vertical distance constraint to a non-zero number.
Hi I am very new to FreeCad and having a little difficulty coming to terms with it. Freecad construction line Manipulating FreeCAD objects Let's start by creating a new empty document: doc = FreeCAD.
