manipulating angles between two bodies

      Hello,


      I was wondering if there was a way to input an exact angle between two bodies as indicated below

      Here is how you could do that in DesignModeler.


        


      The attached file is an ANSYS 18.2 archive.

      Unfortunately since I have version 17, I could not open the file.  So the gist of it was that you drew a sketch of the body outline?

      Yes, but I added some symmetry constraints so the points would stay on the planes. Do you have 17.2?

       I have version 17.0.  It should still work the same there, right?

      Here is my video recorded using 17.2

      In SC, when you use an annotation dimension (forced to be in a plane) accessed in the Detail tab, you can dimension between the cones:


       


      A Pull of geometry (here the vertex at the apex of one of the cones) can change the geometry directly (offset or in a direction by some amount):


       


      Or by linking the pull to an existing annotation dimension with the spark that shows up:


       


      Allowing the Linear Pull to be driven by the Angular annotation dimension.


      This can be stored as a reusable Group (Ctrl-G):


       


      And perhaps more interestingly, can also be used to drive Pull and Move amounts to solve some desired Mass Property (here Volume drives the linear Pull):


       


      The trick there is to make sure to select the desired mass property while the pull dimension is active.
