<h2><span class="mw-headline" id="Description">Description</span></h2>
<p>The View tool adds a representation of one or more objects to a Drawing page. This is the basic building block of the TechDraw module. Most other Views are derived in some way from NewView.

<p>(1) these properties are common to all View types.

<h2><span class="mw-headline" id="Scripting">Scripting</span></h2>
<p>Views can be added to Pages using Python.
</p>
<pre>view = FreeCAD.ActiveDocument.addObject('TechDraw::DrawViewPart','View')
rc = page.addView(view)
FreeCAD.ActiveDocument.View.Source = [App.ActiveDocument.Box]
FreeCAD.ActiveDocument.View.Direction = (0.0,0.0,1.0) </pre>
<h2><span class="mw-headline" id="Notes">Notes</span></h2>
<ul><li> View will draw anything with a Shape property. You can select Draft objects or Bodies also. View will also extract any shapes from objects within an App::Part container or a DocumentObject Group.</li>
<li> Projection Direction property: This vector controls the direction from which you are viewing the object. +X is right, -X is left, +Y is rear, -Y is front (looking into the screen), +Z is up and -Z is down. So a Front view is (0,-1,0) and an isometric view is (1,-1,1). </li>
<li> CoarseView can be much faster for complex models. The quality of the drawing is reduced, since every curve is approximated as a series of short line segments. Vertices are not displayed in CoarseView since each short segment would result in two new Vertices and the display becomes cluttered. Linear Dimensions can be added to a CoarseView, but are unlikely to be useful.</li>
<li> Note that CoarseView is affected by an upstream bug in OCCT (<a rel="nofollow" class="external text" href="https://www.freecadweb.org/tracker/view.php?id=3332">#3332</a>) which causes the View's position on the Page to be slightly off from the specified X,Y values.</li></ul>
