TechDraw NewProjGroup/ro

Descrierea
Instrumentul ProjectionGroup creează proiecții ortografice multiple (https://en.wikipedia.org/wiki/Multiview_orthographic_projection) of one or more 3D objects (Body or Part). Optionally, isometric views of the 4 front corners can be included.



Note that if you only want to produce a single View, there is no advantage in using ProjectionGroup to do so, and in fact creating the View in Projection Group may take considerably longer than the equivalent basic View.

The ProjectionGroup tool creates multiple orthographic projections of one or more 3D objects. Isometric views of the 4 front corners can be included.

If you only want to produce a single view, there is no advantage in using ProjectionGroup; you should use TechDraw NewView instead. If you do not wish to use the traditional First/Third Angle view layout, you should use multiple TechDraw NewView instead of ProjectionGroup.



Cum se utilizează

 * 1) Select one or more Body and/or Part objects in the 3D window or tree.
 * 2) If you have multiple drawing pages in your document, you will also need to select the desired page in the tree.
 * 3) Press the  button
 * 4) A dialog will open in which you can select which views should appear in the group, the group's scale and other parameters.
 * 5) You can move the group as a whole by dragging the central view.  You can also move individual views by dragging.

Proprietăți

 * : The central view in the group. Normally the Front view.
 * : "First Angle" or Third Angle".
 * : If true, space out individual views automatically. Use false to position manually.
 * : Horizontal space between views when automatically positioned.
 * : Vertical space between views when automatically positioned.

 * : Horizontal space between views when automatically positioned. Note that Scale and the size of other views in the group also influence the spacing.
 * : Vertical space between views when automatically positioned.

Notă: The ProjectionGroup as a whole inherits X,Y,ScaleType,Scale and Rotation from the basic View. Note: Individual Views within the group inherit all part view properties, but the ProjectionGroup object controls the scale of all its member Views.

Individual Views within the group inherit all part view properties, but the ProjectionGroup object controls the scale of all its member Views.

Note that the central box displays the current projection direction of the primary view. It cannot be used to change the direction.

Script
PojGroups pot fi adăugate la Pages utilizând Python.

TechDraw API and FreeCAD Scripting Basics.

The NewProjGroup tool can be used in macros and from the Python console. A full script is available in the Source distribution in "source-dir/src/Mod/TechDraw/TDTest/DProjGroupTest.py".

Programming note: The Projection Group should always be added to the Page (ex. page.addView(group) before adding projections to the Group. This allows the Projection Group to use default parameter values derived from the parent page.
