This command allows to modify the sketch behavior by sewing or not profiles together, by verifying or cleaning automatically the sketch, by managing the splines extension of the editing sketch.

 

Creation stages / Use:

 

Select the 3D sketch > Options... command from the drop-down menu.

 

 

Allows to specify the accuracy of the curve projection on surface. The more the value is small, the more the result is accurate. This option is only used by the command Spline on Shape.

 

Allows to set the size of the planes that could be created selecting a point of a 3D sketch by right click.

 

The Large radius value is a step at which a circle will be deformed differently during its resolution by the solver.

Below this threshold, for a rather short radius, it will not be able to change the sign of curvature and will always remain on the same side of the chord. This curvature sign change can be seen using the deformation command.

Otherwise, if the radius becomes to large, it could cross its chord and reverse its curvature.

 

 

  • The large radius option has only to be use for uncommon cases like a radius of several kilometers for railway rails.

  • The default threshold is set to R = 1m which correspond to a diameter of 2m. We highly recommend that you do not change this numerical threshold.
