TechDraw "Штриховка"
Описание
У 
верстака TechDraw есть два инструмента штриховки:
Штриховка плоскости с использованием файла изображения (плиткой)
Назначением плоскости геометрической штриховки (с помощью линий)
Использование
- Выберите грань
- Исходя из необходимости, нажмите иконку TechDraw Hatch или TechDraw GeometricHatch.
Результат: Грань будет заштрихована в начале с использованием значений по умолчанию. Примечание: Редактируйте параметры штриховки для получения нужного рисунка.
Hatch Face using Image File
Hatch Face using Image File utilizes SVG or bitmap based tiles to cover the selected Face.
SVG tiles are typically 64x64 pixel images. Some examples are available on GitHub.
Any bitmap file can be used (png, jpeg, etc...) as a fill. Note: Results are best with many small repeated images rather than fewer larger images.
Default Hatch fills can be specified in TechDraw Preferences.
Geometric Hatch
Apply Geometric Hatch to Face forms a pattern of lines based on a specification read from a file. This file is generally compatible with the widely used AutoDesk® PAT format. A small selection of patterns is included in the FCPAT.pat file:
; standard PAT patterns
*Diamond, 45 diagonals L & R, Solid, 1.0 mm separation
45,0,0,0,1.0
-45,0,0,0,1.0
*Diamond2, 45 diagonals L & R, Solid, 2.0 mm separation
45,0,0,0,2.0
-45,0,0,0,2.0
*Diamond4, 45 diagonals L & R, Solid, 4.0 mm separation
45,0,0,0,4.0
-45,0,0,0,4.0
*Diagonal4, 45 diagonal R, Solid, 4.0 mm separation
45,0,0,0,4.0
*Square, square grid, Solid, 5.0 mm separation
90,1,1,0,5.0
0,0,0,1,5.0
*Horizontal5, horizontal lines, Solid 5.0 separation
0,0,0,0,5.0
*Vertical5, vertical lines, Solid, 5.0 separation
90,0,0,0,5.0
You can add your own patterns if you have write permission to FCPAT.pat, or you can create your own *.pat file and point to it in TechDraw Preferences.
