Description

Cette macro crée une face et un sketch avec les éléments sélectionnés d'un fichier DXF.

Utilisation

• Importez un fichier DXF
• Sélectionnez les éléments à convertir
• Lancez la macro, les éléments sélectionnés sont analysés et convertis en faces et en sketch (pour obtenir une face le fil doit être fermé).

Options

• Modifiez create_face=True ou create_sketch=True en False pour généré un seul objet

Script

Macro DXF to Face and Sketch.FCMacro

##    Select the items to be processed
##    Launch the macro, all selected objects are analyzed and transformed into faces and sketches.
##    change create_face=True or create_sketch=True to False to generate only one item
## todo: fix closed curves for bsplines method
