Draft Shape2DView/pt-br

Descrição
The Draft Shape2DView command creates 2D projections from selected objects, usually 3D solids or Arch SectionPlanes. The projections are placed in the 3D view.

Draft Shape2DView projections can be displayed on a TechDraw Workbench page using the TechDraw DraftView command. Alternatively the TechDraw Workbench offer its own projection commands. But these create projections that are only displayed on the drawing page and not in the 3D view.



Utilização

 * 1) Optionally rotate the 3D view. The camera direction in the 3D view determines the projection vector. For example, a top view will project onto the XY plane. The projection vector is ignore for projections created from Arch SectionPlanes.
 * 2) Optionally select one or more objects.
 * 3) There are several ways to invoke the command:
 * 4) * Press the button.
 * 5) * Select the option from the menu.
 * 6) If you have not yet selected an object: select an object in the 3D view.
 * 7) The projected objects are created on the XY plane.

How to produce plans and sections with different linewidths


Drawings with different linewidths for viewed and cut lines can easily be produced by using two shape2Dview objects from a same Arch SectionPlane. One of the shape2Dview objects has its projection mode set to Solid, which renders the viewed lines, and another set to Cut lines or Cut faces to render the cut lines. The two shape2Dviews are then placed at the same location, one on top of the other.

Propriedades

A Draft Shape2DView object is derived from a Part Part2DObject and inherits all its properties. It also has the following additional properties:

Data

 * : specifies if the projection should be automatically recomputed if the object changes. Selecting  can be useful if there are many Draft Shape2DViews in a document or if they are complex. If set to  the Std Refresh command must be used to update the projection.
 * : specifies the object to be projected.
 * : specifies the indices of the faces to be projected. Only works if is.
 * : specifies if Arch objects of the same type and material are fused or not.
 * : specifies if hidden lines are shown or not.
 * : only works if the selected object is an Arch SectionPlane, and is  or, specifies if the projection will appear co-planar with the section plane.
 * : specifies the direction of the projection. Ignored if is an Arch SectionPlane.
 * : specifies the projection mode. The following modes are available:
 * : projects the entire selected object.
 * : only projects the faces in the list.
 * : only works if the selected object is an Arch SectionPlane, projects only the edges cut by the section plane.
 * : only works if the selected object is an Arch SectionPlane, projects the areas cut through solids by the section plane as faces.
 * : projects the entire selected object by cutting faces one by one. Can be used if the mode gives wrong results.
 * : specifies the size in millimeters of linear segments if is.
 * : specifies if tessellation should be performed. Tessellation means that curves are replaced by sequences of line segments. This can be computationally intensive if the is too short.
 * : specifies if the projection should only be recomputed if it is visible.
 * : A list of exclusion points. Any edge passing through any of those points will not be drawn.
 * : A list of object names. Any viewed or cut child object with a name in that list will not be drawn.

Vista

 * : not used.

Scripting

To create a 2D projection use the method  of the Draft module. This method replaces the deprecated method.


 * is the object to be projected.
 * is the projection vector. If not supplied the Z axis is used.
 * is a list of face numbers (0-based). If supplied only these faces are considered.
 * is returned with the created 2D projection.
