Tangent

Menu access: Shape | Other shapes | Tangent

Description:

Allows you to create a surface tangent to an existing surface relatively to a curve or isoparametric of this surface.

General philosophy:

  1. Select the reference surface.

  2. Select the origin of the tangent surface (ISO or CURVE).

  3. Give the length of the tangent surface and valid with  OK .

Available option(s):

There is two type of origin to build the tangent surface:

  ISO

You need to indicate the parameter (between 0 and 1) that define the position of the isoparametric on the surface depending on the U or V chosen direction.

Choose if you want to build it  PERPENDICULAR TO CURVE  or along  ISOPARAMETRIC

 CURVE

You can select in the drop down list along which element you want to build the tangent surface.

You need then to select the reference curve.

It's possible to invert the created surface direction by using the  INVERT DIRECTION  button.

Example(s):

Tangent surface (yellow) using an ISO :

  1. parameter 0,5,

  2. parameter 1.

Tangent surface (yellow) using a CURVE (red) relatively to an isoparametric (blue).

 

Specific point(s):

The selected isoparametric is displayed on the reference surface.

The choice of the isoparametric has a great influence when using the curve option.

The tangent surface is computed on the untrimmed surface.
