Creating Splines

Select two or more points where the spline is to be created.
An updated spline is visualized each time a point is selected. You can edit the spline by first selecting a point and then doing either of the following:
- Click to add a line at the end of the list in the table.
- Click to insert a line before the selected line in the table.
- Click to insert a line after the selected line in the table.
- Click to remove all the lines.
Select Geometry on support and then select a support (a plane or a surface), if you want the spline to be projected onto a support surface.
It is better when the tangent directions belong to the support, that is when a projection is possible. In this case, select a surface or plane.
Optional: Select the Close Spline check box to create a closed curve, provided the geometric configuration allows it.
To specify tangency conditions onto any point of the spline, select the point and click Tangent Direction in the table.
To set a curvature constraint at any point of the spline, once a tangency constraint is set, indicate a curvature direction and enter a radius value.
Click OK to create the spline.

Important: You cannot create a spline of which points have a distance lower than the resolution.
