![]() ![]() The simplest polynomial connecting 2 points is a line ( A ∗ x 1 + B. Bézier curves provide this feature.īézier curves are polynomials to describe the connection between 2 points. So a curve with which you can connect two points tangentially to a reference point can be very useful for constructions. Option 3: you could save some more volume if the connection between the 2 points is a curve that begins tangentially at (0, 20) and ends tangentially at (80, 40):.But at the bottom you don't need immediate support. To save volume, the arc should end tangentially in point (80,40). Option 2: you can connect the two points with an arc of a circle.However this solution needs a lot of volume, thus weight and material. Option 1: you could add a line from point (20, 0) to point (80, 40):.Therefore you need to add a support directly to your part. Outer support structures might not be an option. The FreeCAD Sketcher Workbench is used to create 2D Sketches intended for use in the PartDesign Workbench, Arch Workbench, and other workbenches. You have to print the part in direction of the sketch's bottom to the top. Let's assume you want to design a part that should be produced with a 3D printer. If you know already about B-splines and their application, you can directly continue with section B-splines in FreeCAD. It gives also background information what B-splines are and for what applications they are useful. I had some previous AutoCAD experience which helped.This page describes how to use B-splines in FreeCAD. Of course it does mean learning how to use another program. You may wish to consider a dedicated software program for technical drafting instead, such as LibreCAD or QCad."įollowing this official advice I have found LibreCAD to be a nice enough 2D CAD package for my modest needs. The Draft workbench would be an alternative but even the FreeCAD wiki says: "If your primary goal is the production of complex 2D drawings and DXF files, and you don't need 3D modelling, FreeCAD may not be the right choice for you. Many common tools are missing plus it will choke if there are too many elements/constraints.Įspecially if your design contains many repeating/patterned features, Sketcher will NOT be happy about it. As the name already implies it's just not a full drawing program. But for more ambitious 2D work you will find the Sketcher lacking. The approach as described will probably work for very simple designs.
