- 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 version 0.21
- Use New Face Finder Algorithm: If checked, the new face finder algorithm will be used instead of the original one. introduced in version 0.21
- Auto Correct Dimension Refs: If checked, an attempt is made to update dimension references when the model changes. introduced in version 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
- Allow Crazy Edges: Includes edges with unexpected geometry in results, e.g. zero lengths
- Debug Section: Dumps intermediate results during a Section view processing
- 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 version 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.
