Why is it that once an arc is placed I can't drag the radius...

Dave Klimas Jul 30, 2012 8:02 PM

Instead it moves my arc. Or maybe it's changing the radius AND moving the endpoints?

Is there a trick to dragging the arc radius without moving the endpoints of the arc and not giving it a radius dimension or fixing the endpoints?

It works as expected when first creating the 3-point arc. But when I try to edit it, dragging moves it instead.

It would be nice if the endpoints didn't move unless I pick them and drag. Something doesn't seem right.

Are you dragging the center point or the arc itself? It should be that dragging the center moves the arc and dragging the arc changes the radius. Atleast that's how mine works.

  I'm grabbing the arc itself.
  
  Oh, I forgot to mention that the arc was mirrored about a centerline and that's when it started to act different.

    Could you please upload a screenshot?

      The single arc on top can be dragged as expected. End points don't move.
      
      The arcs on bottom are mirrored. Left is a mirror of the right. I can't drag the radius (of either) like I can with the top arc.
      Maybe it's dragging the radius, but on a much larger scale if that makes sense. So the arc length remains, but the radius is changing about the center.

Ok, I figured it out.

Because I can't get constraints to display I didn't realize it was giving a symmetrical relation to the centers as well when I mirror it. Once I delete the center symmetrical relation I can drag it as expected. Also, highlighting the sketched arc doesn't reveal the center symmetrical relation, it only shows the symmetrical relation of the arc. This is why I wasn't catching it.

  When mirror is used there is nearly always (more likely always) a symmetric relation added to some point of reference. these are good most of the time but need deleting other times depending on what you are trying to do. glad you figured it out.

  Issue 1. The only way I can get relations to display is to select a sketch entity.
  
  Issue 2. It doesn't show all the relations associated with that same entity. I have to select the center of the arc to know it's there. Annoying bug I haven't been able to fix with any graphics driver so far.

    Seems odd that the arc and center relations are treated separately when I highlight the arc.

    If you go to View>Sketch Relations make sure that it is highlighted (selected on) see if that helps.

      Thanks for the replies my friend.
      
      Yep, sometimes if I toggle that on and off it will fix it. Sometimes not.
