 * 2) There are several ways to invoke the tool:
 * 3) * Press the button.
 * 4) * Select the option from the menu.
 * 5) A task panel will open which will help calculate the various properties. Reasonable values for the view Direction are calculated, but these can be changed.

Properties Base View
A Section view inherits all applicable properties of the view specified as. In the properties of this view you can change the appearance of the section line:


 * : The section line color.
 * : The section line style.

The default settings for these parameters are set via the settings Section Line and Section Line Style in the TechDraw preferences.

Примечания

 * Section Line Format: two section line formats are supported (as depicted above) and controlled by the Preference setting "Section Line Standard" on the Annotation tab. The option uses "pulling arrows" (known as the "traditional format" in some areas) and the  option uses "pushing arrows" (also known as the "reference arrow format").
 * Fuse Before Cut: the section operation sometimes fails to cut the source shapes. If Fuse Before Cut is true, the source shapes are merged into a single shape before the section operation is attempted. If you encounter problems with the section operation, try flipping this value.
 * Trim After Cut: the section cut operation sometimes leaves behind a portion of the source shape. If Trim After Cut is true, an additional cut operation is performed on the result of the first cut which should remove any unwanted pieces.
 * Cut Surface Display: the cut surface can be hidden, painted in a solid color, hatched using an Svg pattern (default) or hatched using a PAT pattern. See Hatching.
