Show and Clear
To assign and free constraints efficiently, it is important to know what constraints are currently assigned. Show and Clear work with the limit-options and constraint-type settings to selectively display and hide the icons and parameter labels of constraints currently on the part. Neither function affects the constraints themselves, just the display of their icons. Icons and parameter labels are displayed in the current show color (PD_PREVIEW_COLOR) and size. Parameter labels will use each dimension's text font for dimensional constraints and the current text font for geometric constraints.
Show and Clear operate identically. To use either:
1. In Generate Constraints, click the Show or Clear radio button.
2. Select an option to limit the function's effect, if desired.
3. Select the Types to show/clear.
Show options are additive; subsequent calls to Show do not erase the icons that are already on the screen, allowing you to build up the display. From time to time, as the display gets crowded, you can erase some or all of the icons with Clear.
Some Show examples:
Show all constraints:
Show, All Types
Show constraints set by Complete:
Show, System, All Types
Show reference elements set by the user:
Show, User, Refelem
Show angle and distance constraints:
Show, Angle, Show, Distance
Erase all constraint icons:
Clear, All Types
