383 forum posts 71 photos | Not being familiar with MOI, I could understand what you were doing it it was done! I don't know if I could replicate that in DesignSpark or SolidEdge. Very elegant. |

10668 forum posts 2415 photos | Nice! The twist capability shown at the end is super. Next time I fire up Solid Edge I'll look for an equivalent. Off-hand, I don't think it has one. Dave |

474 forum posts 103 photos | You can use either a lofted extrusion or a profile swept along a path, with the twist sub-option enabled to achieve the same result in Solid Edge. In either case, you would put the twist in from the start, not make the part then twist it. |

2147 forum posts 222 photos | Very interesting Eddie. I think I could do most of that in SE and (to my mind) some aspects of using SE seem easier than how you did it using MOI (from a UI perspective) but as always with CAD, I believe that "you like what you know". The operation I haven't tried to do in SE was the 'twisting' at the end. I'm pretty sure SE can do something similar but is let down by its User's current level of expertise (or lack thereof) As an aside, I started playing with variable tables in SE yesterday and found that I could set up simple objects that were somewhat like Open SCAD models, where you just change key named variables and the whole model is updated immediately. I don't have an immediate use for them but did enjoy exploring the basics... I've put the knowledge in my "May Come in Useful Later " box for now Regards,

10668 forum posts 2415 photos | This is Solid Edge. The twist, which I expected to be the hard part, is easy. Rounding is usually trivial in SE but not this example! I can't get the tool to follow the edges all the way round. Might be doing it wrong - there's a bunch of settings I haven't tried, and don't understand. Dave

25215 forum posts 3105 photos 1 articles | Gary and Dave look to have taken the easy route with a straight ctr section rather than the dogbone that Martin and I have done with the 125mm radius which did need quite a bit more work in Alibre than MOI to get it to twist than a straight section would Edited By JasonB on 28/04/2023 18:39:07 |

1885 forum posts 111 photos | Pleasantly surprised to see others joining in. Did anyone use the Loft or Sweep tools to do this, instead of Twist?

25215 forum posts 3105 photos 1 articles | I used loft as could not seem to do the dogbone shape with anything else, that was the long winded bit as I needed to loft 4 rectangles and pick up their lengths from a 2D sketch. My Ends are 10mm dia and you can see from these sketches that I had to use various sizes to form the rectangles to loft, the 5mm thickness is constant

441 forum posts 29 photos | The CAD twist function is fantastic, but why would you need to manufacture this item with a twist - would that be stronger than simply designing it so the shaft with the single eye was kept straight but attached to the U piece 90° further round ? .......I'll get my coat. |

You're right, nobody would machine a part all over and then twist it for the other end.
But a link that only needs a drilled hole at each end at 90° makes perfect sense made from a length of twisted bar. Which would be modelled like these were. I must have a go when I've finished my roof-bar ladder clamps. And done the welding on the Metro. |

25215 forum posts 3105 photos 1 articles | Really, I've twisted several parts for models, no doubt the blacksmith who made the full size many years ago would have done the same. How would you model the lower arm on this part? As for the clevis just because the twist was put in at the design stage does not mean it needs to be done as part of making it. Could be lost wax cast or metal printed or maybe it is for an injection moulded plastic part. Edited By JasonB on 29/04/2023 10:21:54 |

It's a fair cop guv'. The easy route is also possible in FreeCAD. I haven't tried to twist a dog-bone yet. MOI seems particularly good at twist operations. I can see why blowlamp likes it. For my purposes Assembly is more useful than twisting, despite Chubby Checker... Dave

307 forum posts 150 photos | Another method in Alibre, is to Loft using two rectangles and four 3D Guide curves (straight lines in this case). These guide curves connect each corner (Vertex ?) of the first rectangle, to the corresponding twisted corner on the second rectangle. Note that this may not work in versions earlier than V25.

Have you done that in Alibre Atom 3D Nick? |

6137 forum posts 893 photos | Looks like 3D sketch which is in the expert and pro versions If they'd put that into Atom 3D it would have been CAD bargain of the year Edited By Ady1 on 29/04/2023 12:00:56 |
