Change to Polyline 
You can find this function in the Object menu or by clicking the 
Change to Polyline button in the Edit Functions Toolbar.
This function is available when a line, area or line text object is selected.
Choose this function to change a line into a polyline. A polyline is an angular line, this means all Bezier vertices are replaced with regular vertices.
Define the Smooth tolerance in the menu Options - OCAD Preferences - category Drawing and Editing.
Change to Bezier Curve 
You can find this function in the Object menu or by clicking the 
Change to Bezier Curve button in the Edit Functions Toolbar.
This opens a dialog and is available when a line, area or line text object is selected.
Choose this command to convert the selected polylines to Bezier curves. The quality of the Bezier curve depends on the number of vertices of the original polylines and the tangent length factor. If the polyline has only a few vertices the distance from the Bezier curve to the original polyline between the vertices can be much bigger than the tolerance value. The closer the tangent length factor gets to zero, the more points are left and the curve looks more like the polyline.
Polyline
Tangent length factor = 1
Tangent length factor = 0.5
Polyline | Curve | Curve with option Convert by keeping straight parts
The Convert polyline to curve dialog is not shown if the Shift key is pressed while clicking Change to Bezier Curve button in the toolbar.- If a hole inside an area object is selected, only the border of the hole is converted.
Define the Change to Bezier curve tolerance in the menu Options - OCAD Preferences - category Drawing and Editing.
