MATE CONCAVE AND CONVEX MODELS

Robert D. Feb 5, 2015 12:02 PM

Has anyone figured a good way to get this type of models to go together? I have tried all mates but I can't seem to get the faces to move relative to each other. When I click mate and select the concave and convex surface of each model of same Radii it does not follow the path of the shape of the models. Any help would greatly be appreciated., Thanks

Robert,

A true concave and convex can be mated with the concentric mate

or

You could add an axis in the center of the shape and mate that with the coincident mate

  I am having trouble figuring out this mating situation..
  I am trying to mate the L bracket to the casting. I keep on getting a distance can not mate when we have drawn it over the top to match the holes.
  can someone please advise what we are missing that this will not mate? I have also thrown the screws in with it.
  
  Thanks for the help

    You had asked this question in another post - pick the vertical face of the bracket and the front plane and choose between - parallel, perpendicular or angular

      I am not understanding the vertical face? this is to line up the L bracket for the screws to be in place?

    Distance between holes in bracket is 0.30452301in
    Distance between holes in housing is 0.30621724in
    Make the distance match and you will be able to mate the other temp axes.
    
    EDIT: The holes in the housing and bracket are not constrained in any direction ... nor is much of the other sketch geometry.

      Are you able to make the changes to the L bracket and upload again?

        Yes I am, but what would you learn from that? Aside from that, I don't know where the holes are supposed to be to accurately align the bracket.
        
        While it isn't always absolutely necessary to constrain every sketch, it is good practice to do so, and in this case the hole locations do need to be properly located & constrained in both parts.
