FreeCAD Surfacing - How to Sweep on 2 Rails |JOKO ENGINEERING|

[@JokoEngineeringhelp]

For those looking to make a solid out of this, go to the Part Workbench> Offset, check the fill offset box and use an offset value less than the minimum radius of curvature. You can also make a closed volume of surfaces and then convert the closed volume to a solid, demonstrated here: kzbin.info/www/bejne/g5rCo2ejnKd6m8k

Truly boggling how you figured this out. Thank you!

[@MrJackPR]

Cool! I am glad I could help you with something. Great video as always!

[@ringding1000]

Another good tutorial! Loved the zoom in on the command buttons for those commands that are new to this tutorial!

[@b.w.oostdam8875]

This is just wonderfull! I was looking for how to do this as I am working on a canopy that requires this!! Super ! Thank you so much!

[@waqar-tech-world]

Thank you so much! You're a life saver!!! ❤️

[@mecanizadosgrela7380]

Thanks for this video, It was useful to me.

[@benoittissier58]

One more excellent tutorial, thank you !

[@leonardochiruzzi7642]

I would like to try to create the bodywork of a car but I see it hard !! always very useful video. Thanks.

[@Kotaztrafee]

This video is for advanced users obviously. Beginners like me need to know each time an action is performed. Such as each time the close button is pressed.

My computer is still trying to create a NURBS from the point cloud. I guess my Bezzy curves were too much. I simplified the curves and got a more simple point cloud but I still get a double surface in one area. Is this Workbench compatible with Ver 0.21.1 ?

[@Miniellipse]

Great tutorial. Maybe you could end with converting the surface to a simple solid since many people want to 3d print after this type of step.

[@JokoEngineeringhelp]

Sure, Part>Offset, check the fill box and make sure the offset is less than the minimum radius of curvature

[@Miniellipse]

@@JokoEngineeringhelp 😀 Thanks!!

[@MrWatsuG]

Your tutorials are excellent! Easily the best there is for FreeCAD. However your microphone audio is quite poor, do you have any plans or ability to upgrade?

[@sergiopappalardo4641]

That was nice! Could you explain how to create thickness in order to get a solid, please? Specially when the part is twisted beyond 360°, I mean creating a thickness normal to the curve. Thanks!

[@JokoEngineeringhelp]

Part>Offset, check the fill offset box. The number one problem that happens is there is a minimum radius of curvature that is smaller than the desired thickness, so make sure that curvature is is large as possible!

[@simonmerrett]

@@JokoEngineeringhelp pin this tip!

[@JokoEngineeringhelp]

@@simonmerrett Done! Thanks

[@powil4ss]

Could you show how to make Reciprocating Grooved Drum?

[@Gassmaninov]

awsome! how would you procede to give this surface a thickness of 1 mm? I aim at 3d-printing of such complex shapes

[@JokoEngineeringhelp]

There is a button for it on the part workbench. You cannot thicken more than the minimum radius of curvature

[@Gassmaninov]

@@JokoEngineeringhelp I know this button. Works unfortunately only with simple solids

[@JokoEngineeringhelp]

@@Gassmaninov That hasn't been my experience, for example I was able to add thickness to the downloadable GrabCAD part in the description without issue. Are we talking about the same button? Utility to offset in 3d

[@Gassmaninov]

@@JokoEngineeringhelp yes, you're right. I was using the thickness button. The offset 3D button works using skin mode and fill option. Thanks!

[@JokoEngineeringhelp]

@@Gassmaninov Glad it's working for you

[@jimmihenry]

This was nice! Maybe i can design a proper propeller in the near future xD

[@3dprintwiz378]

I'm designing a car shell in freecad and when I do an offset to get some thickness in the surface, it does not work. Any suggestions?

[@JokoEngineeringhelp]

There could be a number of causes, the common culprit is there can be a small part of the surface that happens to have a very tight curve. If the curvature (radius) of any part of the surface is smaller than the thickness, surface will not thicken. For other errors, sometimes it helps to thicken less at a time (Break a fender into thickening the fender and fender flares as separate opreations for instance) or use more simple features to define the surface. Hope that helps

[@ladyleni8193]

Nice function, but where can I use this method. The curves cannot be handled or controlled.

[@ИванДмитриев-ф1в]

What do you mean that, cannot be controlled? We can define b-spline, what else do we need? Normal sweep operation, isn't it? Great step for Freecad's users as I think.

[@ladyleni8193]

@@ИванДмитриев-ф1в I used the normal sweep operation with b-spline (look here www.magentacloud.de/lnk/0PLhhd4m).

I am looking to emboss logo in sheet metal. Can that be use.

[@JokoEngineeringhelp]

Sure an easy emboss would be made easily with the new project command on the part workbench. If you want to flatten something, your only option is the sheet metal workbench. I dont think something embossed would flatten properly on sheet metal.

[@simpernchong]

Thanks for the awesome video. However, for FreeCAD to be taken as a serious surfacing tool, the workflow needs to be more streamlined and the result need to be more precise. Just my rambling.

[@henrymach]

And how do we turn that into a closed solid?

[@JokoEngineeringhelp]

You can close it up like here: kzbin.info/www/bejne/g5rCo2ejnKd6m8k Or part>offset and check the fill offset box and use an offset value less than the minimum radius of curvature

[@jwatkins672012]

Why not just use boundary surface command in FreeCAD Surface workbench and skip all these steps? In SWX, not in FreeCAD boundary command yet I believe as on phone at the moment, when using the boundary you can also define the continuity to the edge, especially handy for using suraces to control continuity at the boundary "rails".

[@bobanppvc]

Joko i wait for backhoe design

[@malcolmcolindixon]

Didn't work for me! Crashed FreeCAD too. Possibly too many points in B-spline. Will attempt again tomorrow. Thanks for video though, another tool in the tool belt.
