    If you have the menus active you can toggle off the 3D coordinate indicator from the menu View>Sketch Display>Current Coordinate System Indicator. Then you should be able to select the origin when you start the sketch. Sadly it's not available in the View ribbon.
    Great video!

      Oh, man! Another piece of invaluable information from the Master!!! Thanks Harold!
      P.S. For anyone who doesn't know, you can open the menus by hitting the Alt key.

    It's agreat video K. I think I've watched it 5 or 6 times now. You make it look so easy. I need much more practice 3D sketching guide cruves for lofting and for sure properly constaining the guidelines and lofting faces. Best, Kelly

      Hey Kelly, I am glad you like it. I'm happy that you've learned something from it but I think you're being too modest. The parts you are designing in Alibre and then casting in actual Aluminium are mechanical, automotive, fluid art. Not too many people would be able to do it. Any of it.
      I'm sorry I didn't respond in your forum posts. I am not on it these days. Will be back soon though, I hope. I saw that Harold's got your back there so you're in good hands, indeed!

      ​@@ExMachinaEngineering One of the things you mention in the video is the possibility of 3D sketching on surfaces. I'm particualry interested in this because in my case, I'd like the guidline to be coincident on the parting line, which is centered in the tubular shape, and that parting line surface is usually just simple geometry like and an extruded 2D profile from one of the three principal planes. If there was a way to get points for 3D splines and curves to snap to a surface in a 3D sketch, that would be a very powerful tool for me as it would guarentt the parting line always passes through the center of the tube. I started another thread on the Alibre forum just to prove I still can't make 3D guide curves...🙂 Best, Kelly

    • @ExMachinaEngineering
      @ExMachinaEngineering  5 місяців тому

      I'm not sure I said that. I think I said you can dimension off of surfaces. If you want a sketch on a surface you need Joseph Surface method which you already know.
      I think that with your newly gained skills you'll be able to work with that without the issues you had before

      ​@@ExMachinaEngineering I must have misunderstood. No such thing as a reference surface huh? 🙂I do use and like Joseph's method, but, I've found that just because two surfaces can be perdendicularly constrained to a lofting face, doesn't mean their intersection will be. So great for driving sweeps along surfaces but there's usually still another degree of freedom to nail down to meet the lofting guide line requirements. Easy enough to create a plane normal to the 3D spline after it exists, but for me the size and position of the lofting faces are always established first by engine geometry and the guide line follows. Getting the guideline properly defined is no guarentee that it will actually loft depending upon the inside/outside radius of curvature of the tube......and even after I get by that, no guarentee it will shell. I've had to resort to an internal loft cut in those instances. That's why it's frustrating not to be able to copy a 3D spline.......to drive other shapes/function along the same path. I have to resort to backing up and creating the spline from scratch so I have another guideline available. C'est la vie. Best, Kelly

      Hmmm. I think I see what you mean. But could you not project a previous 3D sketch into a new one? Of course that will create it in the same location.
      Joseph has another video about 3D sketching, the one where he makes bicycle handlebars. He shows there how you can use straight lines as references to drive non-planar splines, and that's another good practice for the parts you usually make. I'll edit this reply in a bit with a link:

    Fantastic video. 3D sketching is just beyond me right now but it gives me a target to learn. Keep them coming.

    • @ExMachinaEngineering
      @ExMachinaEngineering  6 місяців тому

      Yeah, Gary. 3D sketching is one of those things that unless you have a project that you need it for, so that you can apply what you learned, it's really hard to grasp. Maybe because it's so different to 2D sketching and everything else in Parametric modelling.
      But I'm glad you liked the video and I am sure that when you decide to revisit this video, you'll get 3D sketching pretty easily.

      Thanks man! I'm glad you liked it and I'm glad I'm helping you find new tricks in Alibre.

    I'm relatively new to Alibre and curently have Alibre Pro.. Before I invest my time watching this video I would like to know if the Pro version of Alibre has some of the features mentioned in this video such as "cycle planes" which I can't find with my version?
    Thanks, Peter

    • @peterandrade4313

      Disregard my comment above, I was sketching in 2D and not 3D view, my bad...

      Hey, no worries. I hope you find this video helpful and thanks for reaching out even if you did figure it out by yourself!

    so, if i were to ask you if Alibre Atom3d is worth the price the answer would be a definite yes?

    • @stub8453
      @stub8453 6 місяців тому +1

      Alibre Atom3d is definitely worth the price as are it's bigger siblings however check it has the features you want, it's perfect for the 3d printing hobbyist but may be too limited for professional use depending on the application. There is a free trial. This video was made with Alibre Expert and some of the features may not be in Atom.

    • @yibberrino3002
      @yibberrino3002 6 місяців тому +1

      yeah im mostly looking for something not too frustrating and/or time consuming to get started on relatively simple objects @@stub8453

    • @ExMachinaEngineering
      @ExMachinaEngineering  6 місяців тому +1

      Alibre Atom is worth the price. Actually, to be honest, I'm not really sure why it's priced so low.
      I am currently working on an assembly and video of a Cabinet that will be driven off of an Excel Spreadsheet and will be able to generate any size cabinet and as many equally spaced shelves in it as you want.
      And that is all doable in Alibre Atom!!! Plus, Atom is not a hobby licence. It's a full commercial licence. Unlike Fusion, Solidedge, or SOLIDWORKS where there is a cheaper/free hobby version but it is against the EULA to use it to make money... Although, what you see in this video is not available in Atom 3D. I have a playlist on my channel title "Works in Alibre Atom 3D". Everything you see there... well... works in Alibre Atom 3D.
