Did something change in 2008 regarding line relationships?

Steven Mack Mar 25, 2008 3:28 PM

Hello,
I am at my supplier's computer trying to show him our model. They have 2008 on their machine and I'm working with 2007 on ours. His version opened my part just fine, but when I went to show him a sketch of a feature, it showed all my lines as being underdefined, which I was sure they weren't. Long story short... after experimenting a little I determined that "horizontal" and "vertical" seem to no longer have an application with lines in 2008??? Is this right? A bug or something different?

Here's what I did:

Open new part. New sketch. Draw a line. Add horizontal (or vertical) relationship... does nothing. Still shows as underdefined. Physically move the line and now its "over defined" because of the horizontal relationship.

What's up?

They use AutoCAD here almost exclusively so they aren't that familiar and they just got 2008. So do they have a bad install, is there a bug we should know about, or is there a different/better way of defining a horizontal line?

I know I can just fix the lines, but that seems awkward to me. Thanks.

- Steven

Turn Automatic relations back on.

  I'm not quite sure how automatic vs. explicit makes a difference... the relationship is there, its just not defining it!
  
  Anyway, just in case... I looked at the options and that one is checked.
  
  I must not have explained the issue correctly. I have no problem defining a line as being horizontal. "horizontal" shows up in the relationship list and the appropriate icon is on the sketch. However, the line is still blue and "under defined" and I can still rotate it as though "horizontal" means nothing. The same applies for "vertical".
  
  Step by step:
  
  1) Open new part. Start a sketch
  2) Click line tool. Position at the origin and draw a line (so it is coincident with origin)
  3) in the relationship box, choose horizontal.
  
  Line stays blue. Stays underdefined. But it is (should be) now fully defined and should be black and immovable.

    Sorry, I wasn't specific enough...
    
    This "bug" (if it is) only applies to center (construction) lines of infinite length. See attached screenshot. In my 2007, infinate or not, I could certainly declare it as horizontal and it would be black (at least if properly anchored as shown) and immovable.

      It works correctly in my SW2008 x64 sp3.0. Do you know what service pack they were on?

      Steven, Try adding a midpoint or endpoint relation to the construction line. A line can be coincident to the origin and horizontal and still not be fully defined.
      
      Edit: I take that back. I just tried it in 2007 and it was fully defined.

Being that this is SolidWorks and not AutoCAD, I have never used them, but a quick test shows the infinite length construction lines are working fine on my SW2008-SP3.0 install.

I'm curious though, why are you using them? Are you creating infinitely long parts?

  Just simple guides for lining things up. Since they are imaginary lines, there's no reason to define a length to them, is there? When you have no idea at the outset what the geometry of the part is going to look like, but you know its going to be 15 degrees off horizontal then its handy to have a line going off to nowhere in that direction.
  
  Anyway, he says they've never installed a service pack. That could be the issue. Thank you for confirming that on 3.00 it works.
  
  Other than that, 2008 looks pretty cool! Is it worth the upgrade? Or is it more or less just cosmetic?

    I am using SW 8 sp 0.0
    
    I created a sketch with just horizontal and coincident to origin relationships.
    
    Mine shows up as fully defined. see attached.
    
    As I was creating the line it showed as under defined. I deselected the line and reselected it and it showed up as fully defined.

    edit...Sorry I attached the wrong file initially. Attachment should be "fully defined.jpg"

      is your line infinite length though?

Are you sure that it isn't just the ingenious new coloring scheme in 2008? Selected things are now blue.

    Steven,
    
    Your right, I forgot to click the infinite length box. But if I click the fix icon, it becomes fully defined.
    
    I would call it a bug that the horizontal relationship does not force the line to be horizontal. Vertical works correctly, this is weird.

      Steven,
      Perhaps it has something to do with the fact that Infinity itself has never really been fully defined.

      "fix" doesn't mean "repair", it means "fix it in place and don't let it move" so yeah - it would be fully defined then.
      
      I think its a bug too, but aparantly one that has been fixed (repaired) in the service releases.
