TechDraw Preferences

The preferences screens of the TechDraw module are found in the Preferences window (Menu Edit -> Preferences).

Your preference screens may look slightly different depending on platform or formatting scheme.



General

 * Projection Angle - ProjectionGroups will use either First or Third angle projection. (see multiview projection)
 * Hidden Line - the style (solid, dashed, etc) to be used for hidden lines.
 * Detect Faces - if ticked, TechDraw will attempt to build faces using the line segments returned by the hidden line removal algorithm. Faces must be detected in order to use hatching, but there can be a performance penalty in complex models.
 * ShowSectionEdges - highlight the border of the section cut in section views. Usually only for debugging.
 * KeepPagesUpToDate - keeping the drawing pages in sync with the 3D model in real time can slow response times. In complex models, unticking this box will allow for quicker responses.  Use the "KeepUpdated" property of Page to selectively update a single Page.
 * Template Dot Size - Controls the size of the small green dot used for selecting editable text in a Template.
