Converting a line into a Bezier curve

If required, a line may be converted into a curve. In other words, 1D members defined as straight may be afterwards transformed into curved (shaped) ones. This function can treat only one entity at a time.

The procedure for the conversion of a straight line into a Bezier curve

1. Open function Convert line to Bezier:

   1. either click button [Geometrical manipulations with curves] > [Convert line to Bezier] ( >) on toolbar Geometrical manipulations,

   2. or use menu function Modify > Curves edit > Convert line Bezier.

2. Select the entity (just one) that should be converted.

3. Define two control points of Bezier curve.

4. The conversion is done.

Note: If just one entity is selected prior to calling this function, the function itself does not require making of any other selection. The function is applied on the selection made beforehand. On the other hand, if several entities are selected prior to calling this function, the function clears stores the selection, clears it, asks the user to select a single entity for the manipulation, performs the action and restores back the original selection.
