davidwd Posted May 8, 2020 Share Posted May 8, 2020 A simple question but one I cannot fine documentation for . In VW 2020 can I loft two profiles across two rail objects . ie - I have profile at outset of loft and profile at end - between these two edge control rail objects . This must be feasable to control and form but I cannot find the working process . I know I can do this in other software eg "Rhino" but this does not seem to exist in Vectorworks modelling _ or am I mistaken . ?? DD Quote Link to comment
Pat Stanford Posted May 8, 2020 Share Posted May 8, 2020 3D Tool Set, Loft Surface tool. Choose the 3rd mode of the tool, click on the two rails and then the profile. Quote Link to comment
davidwd Posted May 8, 2020 Author Share Posted May 8, 2020 Thanks Pat , But what I am trying to get to- is when I have a defined Profile for outset - ie beginning (one end ) of rail travel , and also a defined (different scale ) nurbs profile for exit of rail travel . Two rails and two profiles . 1st profile and 2nd profile - travel dependant on choice rotation . Does this exist in Vectorworks ? DD Quote Link to comment
davidwd Posted May 8, 2020 Author Share Posted May 8, 2020 or am I missing something simple here ? Quote Link to comment
Pat Stanford Posted May 8, 2020 Share Posted May 8, 2020 I don't think that exists. The closest we have is the first mode of the Loft tool (Loft with no Rail) where you just specify the profile curves. Quote Link to comment
Guest Wes Gardner Posted May 8, 2020 Share Posted May 8, 2020 @davidwd...If I'm understanding you correctly, are you talking about something like Sweep 2 or Curve Network in Rhino? If so, then no, in Vectorworks you're limited to just one profile curve if you choose the Bi-Rail mode, or as Pat suggests, but then you loose the ability to have two rails...

Benson Shaw Posted May 9, 2020 Share Posted May 9, 2020 (edited) Loft >One Rail can have start and end profiles. It has its place, but this is not usually helpful, to me at least. The profiles connect/loft directly to each other, except close to the rail, where a fin is created. Intermediate profiles can be added which gives more control. But then you may as well just use Loft No Rail. The Loft No Rail will produce similar to request if one or more intermediate profiles can be determined and positioned. eg if the two rails exist already, place a new profile connecting all the corresponding inflection points. Profiles need same direction. Then in the Loft tool, click each profile in turn. -B Edited May 9, 2020 by Benson Shaw loft no rail 2 Quote Link to comment
