Std DlgParameter

Description
The Std DlgParameter command opens the Parameter Editor. In the Parameter Editor the parameters that control the behavior of FreeCAD and its workbenches can be inspected and optionally removed, added or changed. The parameters are stored in a file called 'user.cfg', the location of this file depends on your OS.

Working with the Parameter Editor requires some experience. For the most common parameters you can also use the more convenient Preferences Editor.

By default the groups in each tree level in the left panel are sorted alphabetically, and the parameters in the right panel are sorted alphabetically as well. But the order in each panel can be reversed by clicking the 'Group' or 'Name' header respectively.

Quick search
Typing a (partial) string in this input box will fully expand the tree in the left panel and highlight all groups with names that match the entered value. If no matches are found the background of the input box will turn red.

Find

 * 1) In the left panel select the group where you want to start your search. The search direction is down. The search is not restricted to the group and its sub-groups, but rather the selected group and everything listed below it in the tree will be searched.
