Question

problem regarding dimensions witness lines in Creo drawing

I am using Creo Parametric Release 4.0 and DatecodeM150

I am facing some problem regarding dimensions witness lines in Creo drawing. Every time I regenerate, or check-in check-out part, dimension witness line gets disturbed (elongated in/out of view). Problem seen specifically for Parametric dimensions which are converted to ordinate dimension.

Ah, so I see now that your text color is also magenta. That color has been long associated "failed dimensions", which is why that was my initial conclusion.

When dimensions don't correspond to the model upon first opening, I can think of a few reasons:

1.. the config setting for save_display is set to yes that saves a "snapshot" of how the drawing looked but this sometimes shows incorrectly and needs a drawing regen to get the drawing to show correctly. Usually the display is based on a prior model iteration, the model changed and then when the drawing was opened, the  "saved display" showed the old "snapshot"

2. The config option auto_regen_views is set to no, I think this could also be associated with #1. I use this option to help with large assy drawing speed.

3.  the drawing was changed/saved/checked in to windchill but the part/assy model was not checked in. Some detail items, even though they are done in the drawing, are actually saved in the model and require the model to be checked in also.

 

Hopefully these help???

Thak you for your reply. 

I tried all settings you suggested in point 1, but it didn't solve the problem. 

 

I tried to fix witness lines with snaplines, this solve problem for dimension without jogs. But for dimension with jogs gets U like shape as position of jogs cannot fix by snaplines. 

 

Please let me know if you can suggest any alternate solution to this problem. If I get any further solution, will post it here.

Thank you.
