How to use the Additive Pipe Tool in FreeCAD's Part Design Workbench

This video shows you how to use FreeCAD's Additive Pipe Tool which is part of the Part Design workbench. The Additive Pipe Tool to create a pipe from one or more sketches along a specified path in a model. This video shows you how to use the command and demonstrates the limitations in the tool.
The version of FreeCAD used in this video is 0.19.1 22576 built on 11-March-2021. The Linux version of FreeCAD is being used and the environment is Kubuntu Linux 20.04 LTS.

Thanks, multisection (03:03) was just what I needed for my current project. 👍

[@SKpetter]

Thank you for selflessly sharing your knowledge!

[@GlassonDesignStudio]

Thank you for your kind words

[@radekvamowski8092]

old video but exactly what i needed, very good tutorial. btw the hollow pipe is something i needed for designing a part i can 3d print. so very useful for that ;)

[@GlassonDesignStudio]

Thanks for your kind words. I'm glad that you found it useful

[@bassam.2023]

Thanks for this video!

I saw one guy used Frenet in creating spiral thread with a helix in the Sweep tool rather than the specific Helix tool which is now also available. I you don't apply Frenet in rotating a triangle (for example) along a helical thread path, then the triangle twists as it is rotated around the helix and does not make the triangular thread. Soon as you apply Frenet then the Triangle maintains its orientation all the way along the path. The Helical Additive or Subtractive Tool does not have Frenet and does not have the problem of a rotating profile along the helical path. If you want to make a free Helix pathway one goes to the Part WB and chooses the Primitive tool. In the tool one can select a helix and set up its radius, pitch etc. Then return to the Part Design WB. It appears a longer way with pitfalls but there are quite a few other pathways available in the primitives that can be created as well.

Thanks for your feedback. I haven't actually tried any of that so I will take your word for it and try it out at some point. My main use case for FreeCAD is to design furniture and it's rare that we need to design threads but I appreciate you explaining it to me.

please show creation of path to follow along , please.

[@Enjoymentboy]

I'm sorry to ask what is likely an extremely basic and elementary question that I should probably already know the answer to...but how did you create the path line? I'm able to follow along as I watch and the steps make sense, however as I try to do this in FreeCAD I'm getting stuck as I'm unable to create the curved 90° line as you have here in the first example. I am certain I have missed something VERY critical early on in my FreeCAD journey if I can't even figure this out. 🤔

[@GlassonDesignStudio]

Thanks for your question mate. The paths are created as sketches using the Sketcher workbench. You could create the path using the Line and Arc tools in the Sketcher, or you could use the Polyline tool.

[@cyanwaters]

You must be aware of which "plane" to create the path sketch. It's not going to be on the same plane as the profile sketch. Most likely it will be on a plane orthogonal to the profile sketch, but it doesn't necessarily have to be orthogonal.

Nice informative video but the music detracts.

Thanks for the feedback
