TechDraw Preferences/ru

Введение
Экран настроек модуля TechDraw находится в общем окне настроек.

All preferences settings with italic labels are default values for new drawing objects. They have no effect on existing objects.

Drawing Update

 * Update With 3D: Whether or not pages are updated every time the 3D model is changed. This is a global policy setting.
 * Allow Page Override: Whether or not a page's Keep Update property can override the global Update With 3D parameter. This is a global policy setting.
 * Keep Page Up To Date: Keeps drawing pages in sync with changes of the 3D model in real time. This can slow down the response time.
 * Auto-distribute Secondary Views: Automatically distributes secondary views for projection groups.

Labels

 * Label Font: The name of the font for labels. The font is also used for new dimensions, changing it has no effect on existing dimensions.
 * Label Size: Default size for labels.

Conventions

 * Projection Group Angle: If projection groups will use either first- or third-angle projection. See multiview projection for an explanation.
 * Hidden Line Style: The style to be used for hidden lines.

Files

 * Default Template: Default template file for new pages.
 * Template Directory: Starting directory for toolbar button.
 * Hatch Pattern File: Default SVG or bitmap file for hatches.
 * Line Group File: Alternate file for personal line group definitions.

 * Pattern Name: Name of the default PAT pattern.

Scale

 * Page Scale: Default scale for new pages.
 * View Scale Type: Default scale for new views.
 * View Custom Scale: Default scale for views if View Scale Type is Custom.

Size Adjustments

 * Vertex Scale: Scale of vertex dots. Multiplier of line width.
 * Center Mark Scale: Size of center marks. Multiplier of vertex size.
 * Template Edit Mark: Size of template field click handles in mm (green dots).
 * Welding Symbol Scale: Multiplier for size of welding symbols.

Dimensions

 * Standard and Style: The standard to be used for dimensional values. The difference between the standards are shown in the image: TechDraw_Dimension_standardization.png
 * - drawn according to the standard ISO 129-1, text is rotated to be parallel with the dimension line tangent.
 * - drawn in compliance with ISO 129-1, text is always horizontal, above the shortest possible reference line.
 * - drawn according to the standard ASME Y14.5M, text is horizontal, inserted in a break within the dimension line or arc.
 * - drawn in compliance with ASME Y14.5M, text is horizontal, short reference line is attached to one side's vertical center.


 * Use Global Decimals: Use number of decimals from the general preferences.
 * Show Units: Appends the unit (mm, in, etc.) to dimension values.
 * Alternate Decimals: Number of decimals if Use Global Decimals is not used.
 * Default Format: Custom format for dimension text. Uses the printf format specifier.
 * Font Size: Font size for dimension text.
 * Tolerance Text Scale: Tolerance font size adjustment. Multiplier of dimension Font Size.
 * Diameter Symbol: Character used to indicate diameter dimensions.
 * Arrow Style: Arrowhead style for dimensions.
 * Arrow Size: Arrowhead size of dimensions.

Annotation



 * Section Line Standard: Standard to be used to draw section lines in section views.
 * Section Line Style: Style for section lines.
 * Section Cut Surface: Style for section cut surface. The options are:
 * Hide: There is no visible surface.
 * Solid Color: The surface gets the color set for Section Face
 * SVG Hatch: The surface is hatched.
 * PAT Hatch: The surface is geometrically hatched.
 * Line Width Group: A LineGroup to set the default line widths.
 * Detail View Outline Shape: Outline shape for detail views.
 * Detail Highlight Style: Line style of the outline shape for detail views.
 * Center Line Style: Default style for centerlines.
 * Balloon Shape: Shape of balloon annotations.
 * Balloon Leader End: Default style for balloon leader line ends.
 * Balloon Leader Kink Length: Length of balloon leader line kink.
 * Balloon Orthogonal Triangle: If Balloon Leader End is Filled Triangle, the triangle can only get a vertical or horizontal direction when the balloon is moved.
 * Leader Line Auto Horizontal: Forces last leader line segment to be horizontal.
 * Show Center Marks: Show arc center marks in views.
 * Print Center Marks: Show arc centers in printed output.

Colors


Setup of the default colors for new pages:


 * Normal: Normal line color.
 * Preselected: Preselection color. The color that is used to highlight objects when hovering with the mouse over them.
 * Selected: Color for selected objects.
 * Background: Background color around pages.
 * Dimension: Color of dimension lines and text.
 * Centerline: Color for centerlines.
 * Detail Highlight: Line color for the outline shape of detail views.
 * Transparent Faces: If checked, object faces will be transparent. Otherwise the set color will be used for faces.
 * Hidden Line: Hidden line color. This color will be used for all kinds of hidden lines.
 * Section Face: Color of the section view cut surface. Only used if the setting Section Cut Surface is set to Solid Color.
 * Section Line: Color of the section view cut line.
 * Hatch: Hatch image color.
 * Geometric Hatch: Geometric hatch pattern color.
 * Vertex: Color of the selectable vertices in views.
 * Leaderline: Color for new leaderlines.

HLR


HLR stands for hidden line removal.


 * Use Polygon Approximation: Uses an approximation to find hidden lines. This is fast, but the result is a collection of short straight lines.
 * Show Hard Lines: Shows hard and outline edges (visible lines always shown)
 * Show Smooth Lines: Shows smooth lines. A smooth line is a line indicating a change between tangent surfaces, as in the transition from a flat surface to a fillet.
 * Show Seam Lines: Show seam lines. A seam line is a boundary between faces.
 * Show UV ISO Lines: Shows ISO lines. ISO stands for isoparametric. Here is a description what isoparametric lines (in fact curves) are.
 * ISO Count: The number of ISO lines per face edge.

Advanced



 * Detect Faces: If checked, 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.
 * Show Section Edges: Highlights the border of the section cut in section views.
 * Debug Section: Dumps intermediate results during a Section view processing
 * Debug Detail: Dumps intermediate results during a Detail view processing
 * Allow Crazy Edges: Includes edges with unexpected geometry in results, e.g. zero lengths
 * Fuse Before Section: Performs a fuse operation on the input shape(s) before Section view processing
 * Show Loose 2D Geom: Includes 2D Objects in projections, e.g. loose sketches
 * Edge Fuzz: Size of selection area around edges. The fuzz unit is approximately 0.1 mm, depending on your current zoom.
 * Mark Fuzz: Selection area around center marks. The fuzz unit is approximately 0.1 mm, depending on your current zoom.
 * Line End Cap Shape: Setting of the line end cap shape. Explanation of the options: https://doc.qt.io/qt-5/qt.html#PenCapStyle-enum
 * Max SVG Hatch Tiles: The limit of SVG tiles with a size of 64x64 pixels used to hatch a single face. For large scalings one might get an error about to many SVG tiles, then one needs to increase the tile limit.
 * Max PAT Hatch Segments: The maximum hatch line segments used when hatching a face with a PAT pattern.
