![]() ![]() So this should fully constrain the arc, and as chrisb had pointed out, the issue is caused by partial constraint redundancy, and not lack of constraints. The whole arc is created as external geometry in the 2nd sketch, and the normal arc is created using the external center and 2 points. The arc in the master sketch is defined through center + 2 points (a center with 2 points define exactly an arc, actually 2 complementary arcs). You need here to refer to the center and one end of the 1st arc. It allows you to automatize it with scripts, create custom modules, and embed FreeCAD into your own application.You cannot copy an arc with 3 points : an arc is 5 Degrees of Freedom (dof) and 3 points are 6 dof. Multiple FreeCAD reviews prove that this tool is easy to use.It allows you to import and export files in different formats. FreeCAD program for Mac includes a drawing sheets module that generates 2D schematics of the 3D models.It has an OpenCasCade-based geometry kernel that allows running complicated 3D operations on complex types of forms and maintains natively concepts, such as brep, nurbs, boolean operations, or fillets.FreeCAD for Mac provides access from a built-in Python interpreter, macros or external scripts to different components of this 3D modeler, including geometry creation and transformation, the scenegraph, or even FreeCAD's user interface.FreedCAD allows you to modify your design more easily by stepping back into your model history and changing the needed parameters. ![]() Its extensive toolset can be extremely helpful for mechanical engineering experts, architects, and product designers. ![]() FreeCAD software for Mac is an easy-to-use and highly customizable parametric 3D modeler for CAx, CAE, CAD, MCAD, and PLM created primarily to design real-life objects of any size. ![]()
