Q1. How can I select all dimension in a creo drawing view and how can I change all dimensions properties?
Q2. I changed the option of tol_display in drawing properties from no to yes but I haven’t seen the tolerance display with each dimension. Infact I had to select every single dimension and then I changed its tolerance display from nominal to symmetric. It’s very time consuming.
Q1:
Q2:
I think that option only applies to newly created dimensions, not to existing ones or to model dimensions. Also, if you chagned your drawing setup file (*.dtl) on disk that has no effect on existing drawings. When a drawing is created, the settings in the *.dtl file are loaded into the drawing and it becomes independant of the *.dtl file. You then need to either reload the *.dtl file or change the settings in the drawing itself.
Try this too.
(Menu from WF5/Creo)
File->Drawing Options
Scroll down to Tol_display (in the These Options Control Dimension Tolerances section)
Set to yes and then apply.
This should set the current drawing, but you'll need to change the config.pro for it to be in new drawings going forward.
