<p class="Paragraph"><help:help-text value="visible">Here you can make various settings to modify the geometric structure of an object.</help:help-text> The <span style="font-weight:bold;">Geometry</span> icon opens the corresponding area of the window.</p>
<p class="Paragraph">In this area, you'll find the options for changing the geometry of an object.</p>
<p class="Paragraph">An extrusion object is created by dragging a front surface into the third dimension on a path that is vertical to the front surface and whose length is indicated by the <span class="T1">depth</span> value. The back area becomes larger or smaller than the front area by a <span class="T1">scaled depth</span> value that differs from 100%.</p>
<p class="Paragraph"><help:key-word value="rotation object" tag="kw65709_2" xmlns:help="http://openoffice.org/2000/help"/>A rotation object is created when a 2D area is rotated on an axis positioned on the layer of this area. The area will be rotated on a circular path into the third dimension. Rotation objects do not have any <span class="T1">depth</span> values; however, they can show <span class="T1">scaled depth</span> values. If the value for the end angle is exactly 360 degrees, the front area covers the back area of the rotation object.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help"> You can define the degree of curvature for the object's rounded corners in this spin box. </help:help-text> The default 3-D objects (the cube for example) can not be altered. You must first draw a 2-D square, then select the <span class="T1">Convert to 3-D</span> button to create a 3-D cube. Now you are able to round the edges of your object.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">This value describes the scale between the front and back area of a 3-D object. The front area will be increased or decreased according to the percentages given.</help:help-text></p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">This spin box defines the angles of a 3-D object, as long as the object has been created through rotation.</help:help-text> Enter here the value for a circle less than 360 degrees. The result will show a (more or less) open object.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">In this spin box, you can specify the spacial depth of the object in inches. </help:help-text> The settings are applied if , for example, a 3-D object has been created by selecting the <span class="T1">Convert to 3-D</span> button with a 2-D object.</p>
<p class="Head2">Segments</p>
<p class="Paragraph">Enter the number of segments you want to use to compose a 3D body. For example, to convert a torus to a three-dimensional triangle, set the number of horizontal segments to 3.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">Specify the number of horizontal segments in this spin box.</help:help-text></p>

<p class="Paragraph">This area provides additional buttons to change the geometry of the selected object.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">This option represent the object in a manner that is its own: for example, a circle-like object and round area of an object through a circle-like projection, a square-like object and flat area through a flat projection.</help:help-text></p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">Click this button to portray curves as small areas (polygons).</help:help-text> If you want to simultaneously use the "Flat" mode from the display tab page, you must remember that in this case the flat geometry will be applied to the current object.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">Select this option for a spherical object portrayal.</help:help-text></p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">Click here to reverse the illumination ratio of the object so that it lit from the "inside" instead of from the outside. You can see this effect only in open 3-D objects.</help:help-text></p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">For open objects, you can specify identical <text:s text:c="" xmlns:text="http://openoffice.org/2000/text"/>inner and outer illumination. If you've simultaneously activated the Normal reverse option, the object will be illuminated only with the light from its surroundings.</help:help-text></p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">If this button is applied, the 3-D object will be displayed as a closed body also when extended. </help:help-text>This option can be applied to 3-D objects which have been created with an extrusion from a filled freehand line (in which the line crosses itself). The crossing of the 2-D lines will form several single 3-D object parts during the extrution. If the function is assigned as <span class="T1">Show Front/Back</span>, all 3-D object parts will contain complete top, bottom, and side areas. If the function is not selected, only the first object part will be completely closed, the other parts will remain partly open.</p>
