Modifying Constraint Icons
Parametric Design constraint icons are simply text elements whose contents and location are managed by the software. While there is nothing to prevent you from modifying the location, text attributes, or contents of the icons with Creo Elements/Direct Drafting, doing so has several implications that you should be aware of:
• Each constraint icon string is derived from the constraint and from the applicable icon viewing commands (e.g., SHOW and CLEAR). Modifying the contents of the string, or deleting the string altogether, doesn't alter the underlying constraint in any way.
• Copying an icon string or placing the leader line on a different element doesn't copy the constraints to that element. In fact, a copy of an icon string is not recognized by Parametric Design and becomes just another text element that can be added to the zone and constrained!
• Any change in the attributes of an icon string, such as slant, will be forgotten when the entire icon string is cleared from the screen. The next time the icon string is constructed it will use the default settings for new text elements.
• The constraint icon characters are part of the hp_symbols font. These characters are inserted into locations 65-96 of hp_symbols when Parametric Design is enabled. You should not attempt to use these locations either before or after Parametric Design is enabled. Unpredictable results can occur.
