Insert isoparametrics (non associative)

Menu access: Shape | Toolbox | Insert isoparametrics (non associative)

Description:

Allows to add new isoparametric curves along U and V on a b-spline surface.

The associativity of the shape is broken after the insertion.

Inserting new isoparametric curves on a face will allows you to modify more locally the geometry of the face.

Principle:

The function works as follow:

- The selected surface is copied on the current layer.

- The isoparametric curves are added on the copy of the surface.

- The original surface is then replaced by the copy and the shape is basified (associativity is broken)

General philosophy:

1. Select the surface to modify.

2. Choose the isoparametric curve you want to add (according to U, V or both).

3. Click on the surface where you want to add the isoparametric curve or give the ratio value to position it (value between 0 and 1).

4. Validate with  OK  .

Available option(s):

The drop-sown list   allows you to choose the elements you want to visualize while inserting new isoparametric curves.

The option  Continuity = YES  or  NO  allows you to choose if the surface must have a continuity constraint on the isoparametric curve created. This will have an effect on the surface geometry when the control points will be moved (by using the function  "Control points modification").

Example(s):

Specific point(s):

The number of control points depends on the number and density of isoparametric curves on the surface. However, the control points are not always superposed with the isoparametric curves
