I want to Thank you for posting these videos. Your teaching style is exactly what I needed to get back into cad work. I’m going to post another cam video next week about your UA-cam and my experience along with sharing your Patreon
*Creating a Twisted Part in FreeCAD: A Comprehensive Guide to Multi-Section Lofting* * *0:04** Introduction to the Twisted Part Challenge:* The video introduces a common CAD challenge: creating a twisted part. It focuses on using the multi-section loft feature in FreeCAD. * *0:35** Analyzing the Technical Drawing:* The part is broken down into three sections: two identical sections (1 and 3) and a complex twisted middle section (2). * *0:57** Determining Operations:* Based on the analysis, a pad operation will be used for sections 1 and 3, and a multi-section loft for section 2. * *2:27** Connecting Sections:* The transition between sections will share the same profile, allowing the use of a face from one operation as the starting profile for the next. * *3:25** Starting the Modeling Process:* The process begins in the Part Design workbench with the creation of a new body and sketch for section 1. * *6:02** Padding and Symmetry:* Section 1 is padded symmetrically to the plane to ensure the center of rotation for subsequent operations is correctly positioned. * *6:55** Creating the First Loft Profile:* A new sketch is created on a face of the pad, and external geometry is referenced without locking it down via coincident constraints. * *8:14** Avoiding Deformation:* Using equal constraints instead of coincident constraints prevents deformation when the sketch is rotated during the loft operation. * *10:43** Creating Additional Profiles:* The video demonstrates using the "carbon copy" and "duplicate" tools to create additional profiles for the loft, each with different properties and use cases. * *12:51** Duplicating Sketches:* Duplicating a sketch allows for independent modification of the copied sketch's data and constraints. * *13:23** Copy and Paste:* Copying and pasting a sketch allows for multiple instances of the sketch to be created and placed within the model. * *14:33** Creating the Loft:* The loft is created using the face of the pad as the first profile and the subsequent sketches as additional sections. * *15:59** Duplicating Section 3:* Section 3 is created by duplicating section 1, and various methods are discussed, including carbon copy and using a datum plane. * *17:25** Carbon Copy vs. Datum:* A carbon copy creates a linked copy of a sketch, while a datum allows for independent modification. * *19:27** Completing the Model:* The final section is padded and positioned, and the visibility of construction elements is toggled off. * *20:09** Adjusting Transitions:* The video shows how to adjust the transition between the pad and the loft by modifying the position of the sketches used in the loft. * *21:26** Conclusion:* The video concludes with a summary of the process and an invitation for viewers to donate and subscribe.

Thanks! I wanted something similar so used "additive pipe". One question, by moving sketches you control bspline, but this way you never sure that you made it "tangent" is there something I can do to be sure it is?
Good Tutorial! I'm a bit sad, that FreeCAD doesn't give you the option to terminate the guiding b spline as normal towards the starting profile. It's in Fusion and it makes Lofts so much easier to blend into your designs. Here you always have to add another profile right in front of the ends to kinda control the end and that doesn't really work for parts where you don't have consistent cross sections througout the loft... Is there a solution for this? Cheers!
Thank you for these Freecad 1.0 tutorials.👍 I'm almost a beginner and I have a general maybe dumby question to orient myself on CAD, on the very general philosophy of CAD. I tried Plasticity, and the shape you made (twisted part) could be made in much less time than this video lasts, very fast. Obviously without the possibility of parametrizing the object inside that software. But apparently it would be absolutely perfect, and among other things, all in nurbs. Do all professional CADs have this workflow based on modeling via numerical coefficient? In Freecad it is not possible to '''create parameters directly on the mesh'', visually?...I don't know if I'm explaining myself. And if this is not possible, wouldn't it be possible to create for example the object you made in the video in a faster software and then add the precise measurements in Freecad, or modify it in Freecad? I would be happy if you could tell me, eventually, that there is no way around this problem, and the ''extra TIME'' spent to model such a simple shape, but getting precision and other things, is time well spent, and that is what all engineers do.
Another outstanding video! But I have a question: when duplicating (carbon copy) the left end and moving it to the right, you just gave it a 102mm offset. Why don't you need to attach it to the face at the right end of the loft?

Thank you Darren, specially AdditiveLoft part
You great again,
My best regards.
really great workflow!
amazing how you explain everything.
thanks and have a Very Mary Christmas
With a couple of extra varset parameters this becomes a pretty versatile widget.
*Creating a Twisted Part in FreeCAD: A Comprehensive Guide to Multi-Section Lofting*
* *0:04** Introduction to the Twisted Part Challenge:* The video introduces a common CAD challenge: creating a twisted part. It focuses on using the multi-section loft feature in FreeCAD.
* *0:35** Analyzing the Technical Drawing:* The part is broken down into three sections: two identical sections (1 and 3) and a complex twisted middle section (2).
* *0:57** Determining Operations:* Based on the analysis, a pad operation will be used for sections 1 and 3, and a multi-section loft for section 2.
* *2:27** Connecting Sections:* The transition between sections will share the same profile, allowing the use of a face from one operation as the starting profile for the next.
* *3:25** Starting the Modeling Process:* The process begins in the Part Design workbench with the creation of a new body and sketch for section 1.
* *6:02** Padding and Symmetry:* Section 1 is padded symmetrically to the plane to ensure the center of rotation for subsequent operations is correctly positioned.
* *6:55** Creating the First Loft Profile:* A new sketch is created on a face of the pad, and external geometry is referenced without locking it down via coincident constraints.
* *8:14** Avoiding Deformation:* Using equal constraints instead of coincident constraints prevents deformation when the sketch is rotated during the loft operation.
* *10:43** Creating Additional Profiles:* The video demonstrates using the "carbon copy" and "duplicate" tools to create additional profiles for the loft, each with different properties and use cases.
* *12:51** Duplicating Sketches:* Duplicating a sketch allows for independent modification of the copied sketch's data and constraints.
* *13:23** Copy and Paste:* Copying and pasting a sketch allows for multiple instances of the sketch to be created and placed within the model.
* *14:33** Creating the Loft:* The loft is created using the face of the pad as the first profile and the subsequent sketches as additional sections.
* *15:59** Duplicating Section 3:* Section 3 is created by duplicating section 1, and various methods are discussed, including carbon copy and using a datum plane.
* *17:25** Carbon Copy vs. Datum:* A carbon copy creates a linked copy of a sketch, while a datum allows for independent modification.
* *19:27** Completing the Model:* The final section is padded and positioned, and the visibility of construction elements is toggled off.
* *20:09** Adjusting Transitions:* The video shows how to adjust the transition between the pad and the loft by modifying the position of the sketches used in the loft.
* *21:26** Conclusion:* The video concludes with a summary of the process and an invitation for viewers to donate and subscribe.

Thanks for sharing and Merry Christmas to you and your family 😊

Great video
Is it possible to publish the workflow chart you use at the beginning of the video?
Do you have a link to the chart?

I think it would be good practice to name your sketches and other features.
