Closed Nurbs

Image/idearchitectural00090000.gif Click Draw/Primitives/Curve/Closed NURBS.

Image/idearchitectural00090000.gif Determine as many points as you want on the drawing area by left-clicking.

Image/idearchitectural00090000.gif As you determine the points, the closed NURBS curve will take form according to the location of the points.

Image/idearchitectural00090000.gif Double-click to complete curve drawing.

If you want to make any modification on the form of the curve after drawing the curve:

Image/idearchitectural00090000.gif Select the curve that you want to change its form by left-clicking.

Image/idearchitectural00090000.gif Bring the cursor on the nodes on the selected curve. Left-click when the cursor is transformed to OK sign. (The transformation of the cursor to OK sign means that the cursor catches the exactly the related node. To be able to catch nodes the Snap To Nodes mode should be active. If it is not active click Tools/Snap/Snap To Nodes to open it.)

Image/idearchitectural00090000.gif Slide the mouse cursor. The node will move together with the cursor. Complete the process by left-clicking when you come on the point you want.
