To be changed into other distance value different from a specified value when editing Crosshatch Distance. This happens only if trying to edit the crosshatch manually created. Therefore, it doesn't happen for automatically created Crosshatch such as Section View.
Since it doesn't depend on the data, can be easily reproduced with the simple model.
Steps to reproduce: 1. Open a new part > create a simple body like a box solid. 2. Go to Drafting > create View Break such as below picture.( make sure to create the view with a scale other than 1:1 because in case of 1:1 does not happen the issue. Ex, 1:2, 1:5 or etc...) Distance = 5mm Scale = 1/5 3. Insert > Annotation > Crosshatch and select 5mm as Distance > OK. 4. Select the crosshatch > MB3 > Edit. *** You can find a different value comparing to the put one.( It will be 25mm, not 5mm.)
Both of the crosshatch distance for Base View and Section View is 5mm as below. Both of the crosshatch distance for Break Views is 25mm as below even though it's specified with 5mm and put it.
Solution
View Scale factor is ignored. And by an actual distance in modeling environment, the crosshatch is put. So 5mm in drawing is expressed by 25mm if the view scale is 1/5(=0.2). It's the expected result.
Workarounds: one of following The issue can be worked around by specifying a value (of expected distance value/view scale factor) as Distance. Ex. if you would like 5mm in Drawing then put 25(5/0.2=25) as Distance value. or suppressing View Break node in PNT > edit the value to your expected one > unsurprising View Break back.
Notes and References
In the case of crosshatch in views with breaks and a scale that is not 1:1 the distance of the hatch is updated to maintain the visual appearance of the hatch on the drawing. It means the crosshatch is made view dependent and is no longer on the sheet. So, the view scale is applied to the hatch. The phenomenon is as expected for Break View.
The phenomenon has occurred since nx11 or before. ( It means also occurring in all the Continuous Release.)
