# Spline Creation

Splines are 2-dimensional objects created by combining multiple nodes defined by the user with curved lines. Splines can be open shapes. However, if they undergo a transformation, they close automatically, by joining the first point and the last point. It will be sufficient to click the last point on the first point to make a Closed Spline. Splines can be created using Spline-> Case Transform from splines. Splines can be extended into 3-dimensional objects.

Not

Splines cannot be used for space transformations.

To create a spline;

• Click the Draw / Spline line.

• You will see a dialog with Spline Point Number and Spline Degree lines with Undo and Finish buttons .

• Spline Point Number determines the clarity of the line between two joints. It can be at least 2 and at most 50. 8 is the most appropriate value that this variable can take. (Splines are curved lines formed by the combination of straight lines. If you have defined a spline with two nodes and the Spline Point Number is 8, 8 points will be placed between these two nodes and a curved line will be created by combining these points with lines.) .

• Spline Degree determines the slope of the lines. It can be a minimum of 1 and a maximum of 6. 2 is the best fit for this variable.

• After clicking your First Point, a straight line will start moving relative to the mouse.

• After clicking your second point, the first line will slope relative to the second point.

• After drawing a suitable polygon, you can create a Spline by clicking the Finish button in the dialog on the screen .

• If you notice that a point is wrong, you can click the Undo button to delete the points starting from the end in order of their occurrence.

Transformations:

Although splines are created, they do not have any use.

• You can convert a polygon to a vault using Spline-> Case Transform .

• You can make the polygon 3-dimensional using the stretch command.

• Splines cannot be used for space transformations.

To make changes to an existing spline;

• Click on the spline. The spline will turn green and the nodes will become active as red boxes.

• The cursor shape will change when you hover over the node points. In this case, you can click the nodes and move them.

• You can delete a spline by pressing the Del / Delete key on the keyboard .
