Create Dimensional/Geometrical Constraints
To create dimensional/geometrical constraint use the Constraint command.
Click Constraint in the Constraint toolbar (Constraint sub-toolbar).
Select the circle.
The circle diameter constraint is displayed.

Select the line.
The relation between the two elements is reconsidered. In other words, the circle diameter constraint is no longer displayed.

Click Constraint .
Right-click the line and select Line.xxx object > Fix to prevent the line from moving.
The line is fixed and the anchor, that is the fix symbol, is displayed.

To unfix the line, you can use the Line.xxx object > Unfix contextual command.

Another Geometrical Element
You can apply constraint between the conic and another geometrical element using the Constraint command.
For instance, create
a conic and
