Removing an Expression
Access: To remove parametric relations/expressions:
Display the Edit Parameters dialog or the Sketcher Dimension dialog.
Pick the dimension whose value is to be an expression.
From the dialog displayed in step 1, press the Create Relation button
to enter expression
mode.
When defining expressions in
the Edit
Parameters dialog or the Sketcher
Dimension dialog, you can cancel the expression by pressing
the Create Relation toggle button
. This collapses
the dialog and displays
a numeric value in the dimension field. The numeric value displayed, depends
on whether you are cancelling a new expression (an expression still being
created) or an existing expression.
Note: While this operation can be performed from the Edit Parameters dialog or the Sketcher Dimension dialog, the examples below use the Edit Parameters dialog.
To cancel a new expression:
Press the Create Relation toggle button
in the Edit Parameters dialog. This collapses
the Edit Parameters dialog
and displays the original numeric dimension value in the dimension
field.
To cancel an existing expression:
Select the dimension to display the Edit Parameters dialog in expression mode.
Press the Create Relation toggle button
in the Edit Parameters dialog. This collapses
the Edit Parameters dialog
and displays the numeric value of the expression in the dimension
field.
This action may be used to break a cyclic loop.
Pressing the button
again (during the same or an other session), restores the last available
expression.
