Draft Shape2DView

Description
The tool produces a 2D projection from a selected 3D solid object such as those created with the, , and  Workbenches.

The resulting projection is a Draft object and is placed in the 3D view. This object can be displayed on a Workbench page, using the TechDraw NewDraft tool. Alternatively, TechDraw has its own tools to create projected views, the and  tools; however, these tools are meant for preparing technical drawings, so they create the views only in the drawing page, and not in the 3D view.



Usage

 * 1) Rotate the view so it reflects the direction of the desired projection. For example, a top view will project the object on the XY plane.
 * 2) Select a 3D object.
 * 3) Press the  button. If no object is selected, you will be invited to select one.

The projected object will be created below the selected object, lying on the XY plane. It's position can be changed by changing its properties. The projection direction can also be changed after creation with the property editor.

Note: If the selected object is an, the projection will use the contents and direction of that Section plane; in this case, the "Projection" property will be ignored.

Options
There are no options for this tool. Either it works with the selected object or not.

Properties

 * : specifies the direction of the projection as a vector. For example, (0,0,1) is a projection looking through the Z axis, which would be projected on the XY plane; (1,0,0) is a projection looking through the X axis, which would be projected on the YZ plane; (0,1,0) is a projection looking through the Y axis, which would be projected on the XZ plane. The values can also be negative, in which case the direction of projection is inverted.
 * : it can be "Solid", "Individual Faces", "Cutlines", and "Cutfaces".
 * The default projection is "Solid", which projects the entire selected shape.
 * If only some faces of the base object are selected, the "Individual Faces" mode will project only those faces.
 * If the selected object is an Arch SectionPlane, the "Cutlines" mode will project only the edges being cut by the section plane.
 * If the selected object is an Arch SectionPlane, the "Cutfaces" mode will display the cut areas of solids as faces.
 * : if it is, together with "Cutlines" or "Cutfaces" modes, the resulting projection will appear co-planar with the Arch SectionPlane.
 * : if it is it will show the hidden lines of the projection.
 * : if it is it will perform tessellation of ellipses and splines, that is, it will represent curves with very fine line segments.
 * this may be computationally intensive if is very small.


 * : specifies the size in millimeters of linear segments if is.
 * set a larger value first, and then change it to a smaller value to get better resolution.


 * : if it is the projection will be recomputed only if it is visible.

Scripting

The Draft Shape2DView tool can be used in macros and from the Python console by using the following function:


 * Creates as a projection of the given.
 * If is given, it is a list of face numbers to be considered for the projection.
 * If a is given, it is used; otherwise the default projection is along the Z axis.

The attribute needs to be overwritten with the desired mode, which can be, , , or.
