Dimensions in drawing cause hidden lines to be visible. What!?

[jonesy4000]

I posted earlier about strange problems I'm having with hidden lines being visible in certain viewports and not others. I've found a wrinkle that makes it even more interesting. Anybody ever come across this:

 

I've dimensioned my drawings in model space, which I prefer, and put the dimensions on a separate layer. However, including that layer in the viewport causes the hidden lines to be visible when plotted. If I turn that layer off, everything works great.

 

I have dimensions for the same object in plan view that I'm showing in a different viewport that works just great, but in the front elevation viewport it gets all screwy.

 

I can dimension in paper space just fine and that may have to be the solution, but I really don't like doing that. I prefer to dimension in model space whenever possible.

 

Any ideas?

Are you able to post the file?

I can't post the full file because my company won't let me. But, I made a sample file that has the same issues. Thanks a lot.DimensionHiddenLineProblem.dwg

3 out of 4 dimension and the Mtext in the upper viewport were created on a plane 5357.9695 units below the node that attaches the dimension to the model. I didn't know this would necessarily cause a problem, but I expect that's not really where you want the dimensions to be anyway. I was able to resolve the issue by recreating those 4 objects (shown in red) on the same plane as the other dimension (shown in black)

Weird. I was able to actually grab and move the dimension into the correct plane and that worked just fine. I've noticed that sometimes it places the dimensions on a plane well behind the object, but I've never really thought much of it as long as the dimensions are visible. I don't know why it happens and it seems pretty random to me. Is there someway I can get get the dimensions to be in the correct plane without physically moving them after they're created?

 

I appreciate your help on this.

Dimensions are always created on the current XY plane, so I'd guess something like UCS > View, which is non-specific about defining the origin for the UCS could cause this to happen?

 

If I need to dimension in 3D, I usually create a different named UCS for each view that needs dimensioned, but there are certainly times when you don't want the dimension on the same plane as the objects. I probably never noticed this because I rarely plot hidden visual styles. I learned something new

[jonesy4000]

I've never actually tried to mess with my UCS before. Never really saw the need. Maybe this will give me the opportunity to experiment.

 

Thanks for your help!
