Drawing API example/fr

Introduction
Le flux de travail de l'interface utilisateur graphique pour l' atelier Drawing est limité. Utiliser un script pour l'interface est plus intéressante.

Exemple simple
Vous devez en premier lieu charger les modules Pièce (Part) et Mise en plan (Drawing):

Créez une petite pièce.

Projection directe. G0 veut dire arête vive, G1 est une tangente continue.

Tout est projeté sur le plan Z:

Un autre vecteur de projection

Projeter en format SVG

Exemple paramétrique
Créer le corps

Insérer un objet Page et assigner un modèle.

Créer une vue de votre objet "Shape", définir la position et l'assigner à une page.

Créer une seconde vue de l'objet, le but ici est de faire une rotation de 90 degrés.

Créer une troisième vue de votre objet ici une vue isométrique. Nous activons les lignes cachées.

Changer quelque chose et mise à jour. La mise à jour modifie les vues et la page.

Accéder aux objets et détails
Obtenir des fragments SVG d'une vue.

Get the whole result page (it's a file in the document's temporary directory, only read permission)

Important: free the file!

Insert a view with your own content:

That leads to the following result:



General dimensioning and tolerancing
Drawing Dimensioning Addon

Drawing dimensions an tolerances are still under development but you can get some basic functionality with a bit of work.

First you need to get the gdtsvg python module from here (WARNING: This could be broken at any time!):

https://github.com/jcc242/FreeCAD

To get a feature control frame, try out the following:

Here is a good breakdown of the contents of a feature control frame: http://www.cadblog.net/adding-geometric-tolerances.htm

The parameters to pass to control frame are:
 * 1) X-coordinate in SVG-coordinate system (type string)
 * 2) Y-coordinate in SVG-coordinate system (type string)
 * 3) The desired geometric characteristic symbol (tuple, svg string as first, width of symbol as second, height of symbol as third)
 * 4) The tolerance (type string)
 * 5) (optional) The diameter symbol (tuple, svg string as first, width of symbol as second, height of symbol as third)
 * 6) (optional) The condition modifying material (tuple, svg string as first, width of symbol as second, height of symbol as third)
 * 7) (optional) The first datum (type string)
 * 8) (optional) The first datum's modifying condition (tuple, svg string as first, width of symbol as second, height of symbol as third)
 * 9) (optional) The second datum (type string)
 * 10) (optional) The second datum's modifying condition (tuple, svg string as first, width of symbol as second, height of symbol as third)
 * 11) (optional) The third datum (type string)
 * 12) (optional) The third datum's material condition (tuple, svg string as first, width of symbol as second, height of symbol as third)

The ControlFrame function returns a type containing (svg string, overall width of control frame, overall height of control frame)'''

To get a dimension, try out the following:

Inputs for linear dimension are:
 * 1) point1, an (x,y) tuple with svg-coordinates, this is one of the points you would like to dimension between
 * 2) point2, an (x,y) tuple with svg-coordinates, this is the second point you would like to dimension between
 * 3) textpoint, an (x,y) tuple of svg-coordinates, this is where the text of your dimension will be
 * 4) dimensiontext, a string containing the text you want the dimension to say
 * 5) linestyle, a string containing svg (i.e. css) styles, using the getStyle function to retrieve a preset string, for styling the how the lines look
 * 6) arrowstyle, a string containing svg (i.e. css) styles, using the getStyle function to retrieve a preset string, for styling how the arrows look
 * 7) textstyle, a string containing svg (i.e. css) styles, using the getStyle function to retrieve a preset string, for styling how the text looks

With those two, you can proceed as above for displaying them on the drawing page. This module is very buggy and can be broken at any given moment, bug reports are welcome on the github page for now, or contact jcc242 on the forums if you post a bug somewhere else.
