CATIA Drawing CATScript Features

Scripting Drafting features

One area I have to admit I have neglected to write about in these posts and articles is how to write CATScripts for drafting and 2D drawings. I have not used this workbench myself as extensively as some of the others (like GSD) but I will share any information or tips as I pick up on them. Here we go.

CATIA’s drafting workbench features two basic types of grouping all 2D features: Generative Drafting takes the 3D CATIA objects and represents them in 2D views within a drawing while InteractiveDrafting represents 2D features directly created in the 2D views with no 3D data associated with it.

Scripting Drafting features Overview

Listed below are some of the key features used in macros for CATIA drawings.
  • DrawingSheets and DrawingViews
  • Main View and Background view.
  • ActiveSheet.
  • ActiveView.
  • The Front View and the others
  • Generative Views
  • Interactive Views
  •  Filling the Title block
  • Extract Dimensions

DrawingSheets and DrawingViews

The DrawingDocument object aggregates a DrawingSheets collection. Each DrawingSheet of this collection aggregates a DrawingViews collection.

Main View and Background view.

A drawing contains at least two views: the background view and the Main View, that is the view in which you can draw just after creating a drawing. The ActiveSheet: The active sheet can be found in the DrawingSheets collection. The ActiveView can be found in the DrawingViews collection

CATIA Drawing viewer: The Front View and the others

A DrawingView can be the “Front View” or another view relative to the “Front View”.DrawingViewGenerativeBehavior can define both behavior: DefineFrontView() defines the “Front View” and its direction. DefineProjectionView() defines another view relative to the “Front View”
Other methods allow creating other types of views such as Section Views, Detail Views, etc. Generative Views - DrawingViewowns a “document” property that allows you to specify the associated 3D document from which the “generative view” is created.

Interactive Views - DrawingViewowns a “Factory2D” property that allows you to create 2D features.This kind of view is called an “Interactive View”.

Filling the Title block - The Texts collection allows you to create 2D texts in the drawing

Extract Dimensions - A DrawingSheet has the method called GenerateDimension() that generates dimensions automatically in all the views from the 3D geometry.
