Drawing Update

• Update with 3D (global policy): Whether or not pages are updated every time the 3D model is changed.
• Allow page override (global policy): Whether or not a page's Keep Updated property can override the global Update with 3D parameter.
• 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-angle (European) projection or third-angle (American) projection. See multiview projection for an explanation.
• Section line convention: Standard for section lines that controls the position of arrows and symbol (introduced in 1.0). The options are:
  • ANSI
  • ISO

Files

• Default template: Default template file for new pages.
• Template directory: Starting directory for toolbar button New Page From Template.
• Hatch pattern file: Default SVG or bitmap file for hatches.
• Line group file: Alternate file for personal line group definitions.
• Welding directory: Default directory for toolbar button Weld Symbol.
• PAT file: Default PAT pattern definition file for geometric hatches.
• Pattern name: Name of the default PAT pattern.
• Symbol directory: Alternate directory to search for SVG symbol files.

Selection

• Enable multi-selection mode: If enabled, clicking without Ctrl does not clear the existing selection. introduced in 1.0

View Defaults

• Use 3D camera direction: If checked, the 3D camera direction (or normal of a selected face) will be used as the view direction. If not checked, Views will be created as Front Views. introduced in 1.0

• Standard and style: The standard to be used for dimensional values. The differences between the standards are shown in the image:

  

ISO oriented - drawn according to the standard ISO 129-1, text is rotated to be parallel with the dimension line tangent.

ISO referencing - drawn in compliance with ISO 129-1, text is always horizontal, above the shortest possible reference line.

ASME inlined - drawn according to the standard ASME Y14.5M, text is horizontal, inserted in a break within the dimension line or arc.

ASME referencing - 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 selected and Dimension Format not specified.
• Dimension format: Custom format for dimension text. Uses the printf format specifier.
• Font size: Font size for dimension text.

• Arrow style: Arrowhead style for dimensions.
• Arrow size: Arrowhead size of dimensions.

• Extension gap factor - ASME: Gap between dimension point and start of extension lines for ASME dimensions. introduced in 0.21
• Line spacing - ISO: Spacing between the dimension line and dimension text for ISO dimensions. introduced in 0.21

• Line standard: Standard to be used to draw section lines in section views.
• Line width group: A LineGroup to set the default line widths.
• Hidden line style: Style of hidden lines. introduced in 1.0
• Section line style: Style for section lines.
• Detail highlight style: Line style of the outline shape for detail views.
• Center line style: Default style for centerlines.
• Break line style: Default style for lines used to indicate BrokenViews. introduced in 1.0
• Line end cap shape: The default (round) should almost always be the right choice. Flat or square caps are useful if you are planning to use a drawing as a 1:1 cutting guide.

• 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.
• Grid color: Color for all page grids.
• Template underline: Color for the underline that marks editable texts in templates. introduced in 1.0
• 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.
• Leader line: Color for new leaderlines.
• Transparent faces: If checked, object faces will be transparent. Otherwise the set color will be used for faces.
• Light on dark: If checked text and lines will have a light color. To be used if the Page color is dark. Transparent or light colored faces are recommended with this option. introduced in 0.21
• Monochrome: If checked, the set color will be used for all text and lines. introduced in 0.21
• Page color: The background color of the page. introduced in 0.21

• 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.
• Report progress: Issue progress messages while building View geometry. introduced in 0.21
• Use new face finder algorithm: If checked, the new face finder algorithm will be used instead of the original one. introduced in 0.21
• Auto-correct dimension references: If checked, an attempt is made to update dimension references when the model changes. introduced in 0.21
• Show section edges: Highlights the border of the section cut in section views.
• Fuse before section: Performs a fuse operation on the input shape(s) before Section view processing.
• Switch workbench on click: If checked, double-clicking on a page in the tree will automatically switch to TechDraw and the page will be made visible. introduced in 1.1
• Allow crazy edges: Includes edges with unexpected geometry in results, e.g. zero lengths.
• validate shapes: If checked, input shapes will be checked for errors before use and invalid shapes will be skipped. It can be slower but may prevent crashes. introduced in 1.1
• Debug section: Dumps intermediate results during a Section view processing.
• Debug bad shape: If checked, shapes that failed validation will be saved as B-rep files for later analysis. introduced in 1.1
• Debug detail: Dumps intermediate results during a Detail view processing.
• Overlap edges scrub passes: The number of attempts to remove overlapping edges returned by the Hidden Line Removal algorithm. A value of 0 indicates no scrubbing. Values above 2 are generally not productive. Each attempt adds to the time required to produce the drawing. introduced in 0.21
• Edge fuzz: Size of selection area around edges. The fuzz unit is approximately 0.1 mm, depending on your current zoom. The default is 10. Values in the 20-30 range will make it noticeably easier to select edges. Large numbers will cause overlaps with other drawing elements.
• Mark Fuzz: Selection area around center marks. The fuzz unit is approximately 0.1 mm, depending on your current zoom.
• 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.
• Balloon drag: Modifier key for balloon drag can be changed from the default here to avoid conflicts with OS or navigation style key bindings. introduced in 1.0
