FreeCAD Curves Workbench: Freehand BSpline | Quick Guide

How to use FreeCAD Curves WB tool the freehand bspline. We will learn about the different modes, properties and manipulating the b-spline in Free CAD. We will explore.
- How to create a curve.
- How to add control points.
- How to delete a control point that has been inserted.
- What are segment lines and how to use them.
- Aligning parts of the curve with the view (tangent)
- Aligning parts of the curve with the segment line (Linear interpolation)
- Aligning segments in line.
- Snapping the control points to vertex, edge and face.
- Preselecting geometry to snap the control points to.
- Creating support objects.
- Using the properties.

Looks like mastering BSpline will need more than quick guide. Always wondered how those 3D curves work in FreeCAD. Thanks for the vid.

Great video! Can't wait for FreeCAD 1.0 and all the tutorials that will follow from you.

Wow! This tool is so powerful. Thanks for this guide!

Thanks Again Darren, I was a bit lost using this tool but this video has explained many of its functions.

Oh Master! I should know all of this yesterday when I was modelling gordon surface of my mouse... yhhhh :):):)

[davidrandall]

Ok, got a chance to play with this a bit and I have to say that this made making curves easier. Thank you

Hi Darren, thanks for this tutorial revealing the mysteries of the curves. This way we can draw/modeling more organic shapes. Thank you very much indeed. Greetings from Portugal

Very detailed tutorial!
This is a vital bit of knowledge needed for being able to run wiring for my RC Tugboat project. I have a motor, motor ESC controller, servo, and a battery. These components are all on either the XY or YZ planes and all are on the different "Z" elevations. For example when running the wire(x3) from the motor it comes up and out from the motor and then a short RH 90° turn to a short run then a LH 90° towards the stern and the ESC controller... My point is I simple cure was to create various 3 wire horizontal and vertical 90's then transform tool to align with the various straight sections.
Then select and union the sections. I always knew someday I will get good enough to run the various wire path more from a isometric view and curves is the WB (more efficient).
I also then need to get good at aligning the profile to the end (vertex) of the path. I feel by selecting the profile then right click to "attachment editor" and under "selecting" choose the vertex where the sweep is to start, I think is where is where I need to go next😊? Together with what I added to my toolbox from this video should accomplish my desired results. Sidenote: For the 3 wires together I did create 3 circles of desired "X" dia and overlap the wires a little so that when trimmed gave me my 3 wire look from 1 profile, (you prolly showed me this) so that when different colors are required FreeCAD will let you even though it is 1 profile...
Please advise any changes to my routine that is wrong or there is a better way!
Thanks

Fantastic video. The snap to face is a great, hidden feature. Thanks!!

[nathaliecreuset]

This video is nearly perfect.
But with some feature, displaying into a corner of the screen what is the key, and-or mouse button you are pressing on, that would then be really perfect.

Thank you for the great explantation 🙂

I can see this being used as a path to create things like vehicle break lines.

[DaltoeMusic]

Thanks for the tutorials. Is it possible to connect the two end points of a BSpline to form a closed loop? Have I missed something? Thanks.

[aaronking]

Im having trouble getting the points to move in the table. I follow the exact method shown here, but its hit or miss if the points actually move, or my changes in the table simply are ignored. Ive tried it several different ways, nothing so far has been successful 100% of the time. Im on 1.0.0. Any thoughts on that?

[AerialLensVideo]

How on Earth can a bspline line be copied - or duplicated - in a different area of the same or any other construction plane? Is that even possible?
I have created a scroll line (for an ornamental iron gate project) and cannot duplicate it (or even offset it) at all. I see some sketcher tools that may work(?) in the dropdown, but those are entirely grayed out. Using FreeCAD 1.0.
THANKS for your excellent videos!

Can I use this B-Spline to sweep a path along it for additive pipes in Part Design?

[mdombroski]

Is the curve workbench a new feature? I can't find it.
