    2014 Arc Slot Issue

    Roy Hughes

      When trying to create a 10mm diameter arc slot, I wanted to make the arc 0.5 degrees on a 316mm radius.  I chose to use the Centerpoint Arc Slot where you pick the center, first point of the arc, second point of the arc (roughly setting your arc length) and then pull off from the center to roughly define the diameter.  Upon first trial, I picked the existing center line (in this case the origin), I picked one point and then only moved it a short distance (roughly 0.5 degrees) and clicked the mouse.  This caused the slot command to cancel from all points I just established and return to the start of the Centerpoint Arc Slot where you pick the center.  After the second time of attempting the same steps, I made the arc length about 10 degrees and it allowed me to complete the placement of the arc slot. 


      I then tried to reduce the arc from 10 degrees down to 0.5 degrees by grabbing one end of the arc and moving it manually towards the other end and the arc slot froze and SolidWorks gave me an error, "Invalid Solution Found."  At this point, the entire slot features shown on the menu were frozen.  I deleted this entry and tried again.


      This time I asked a co-worker to watch what was happening when trying to define the arc slot I wanted, repeating the issues above.  He then went to his computer to make sure it wasn't a problem with only my computer.  His computer did the same things I described above.  He then tried to reduce the arc which would take a manual entry of 1.5 degrees without a problem.  He learned by trial and error that if you reduced the arc in small increments, you could eventually get to 0.5 degrees (for example, input 1.25 degrees, 1.0 degrees, and so on).  However, when he got to less than 1.0 degree, it wouldn't respond to his input of, ".5."  So, he tried inputting, "0.50" degrees and it worked. 


      On my computer, I had to reduce the arc in smaller increments to get it to the desired 0.5 degrees. 


      Anyone have any idea on what is going on here?  In 2013, this was not an issue.


      We are running 2014, SP03.

          I think the problem that was happening when you tried to drag the end in was that it was snapping the end to the centerpoint of the arc, and that's why it couldn't find a valid solution. If you zoom in a lot you should find that you can drag the end in to around .5 degrees just fine.


          As far as inputting the angle into the box under slot parameters not working, I think that is definitely a bug and you should report it to your VAR.

              I've seen the same problem that Roy is describing while snaps are turned off so I don't think that's the cause.


              While sizing an arc slot, either by dragging or dimensioning, Solidworks throws a fit if you resize the arc angle to a small value. The only workaround I know of is gradually reducing the arc angle in increments (which is very time consuming). If anyone else has a solution, I'd love to hear it.

                  Dragging works fine for me if I disable snaps, or if I zoom in. The one thing that does mess it up even if snaps are disabled is if I drag the endpoint of the arc all the way onto the centerpoint, then it gets stuck and I have to undo and try again.
